1

00:00:02,010 --> 00:00:07,710

So now we want to improve our calendar, we want it to when we were looking at a given month, if there



2

00:00:07,710 --> 00:00:13,860

is a block, if the owner is closed, the room for, say, these three dates for the generals quarters



3

00:00:13,860 --> 00:00:20,160

for the seventh, eighth and ninth of December, these should show up checked.



4

00:00:20,700 --> 00:00:25,530

And if there's a reservation, say, on the second and third, we shouldn't see checkboxes at all.



5

00:00:25,530 --> 00:00:30,360

We should see some indication that there is a reservation for those dates and clicking on it should



6

00:00:30,360 --> 00:00:31,610

take us to that reservation.



7

00:00:32,160 --> 00:00:32,910

So let's get started.



8

00:00:33,840 --> 00:00:41,030

So right now in our handler over here, let's find our handlers right here.



9

00:00:41,670 --> 00:00:46,920

So I'm inside the handlers file looking at the admin reservations calendar method or function.



10

00:00:47,520 --> 00:00:49,140

And right now I have the rooms.



11

00:00:49,590 --> 00:00:52,350

I have the room stored in this variable rooms.



12

00:00:52,890 --> 00:01:01,590

And what I want to do is to somehow store information about the current blocks and the current reservations



13

00:01:02,370 --> 00:01:08,190

in a data structure that I can pass to my template so I can use that to determine how to render the



14

00:01:08,190 --> 00:01:08,690

calendar.



15

00:01:09,090 --> 00:01:12,270

So if you look back at the calendar, there's a couple of ways you might do this.



16

00:01:12,450 --> 00:01:18,990

You could say write a function and add it to our render package that says every time you're about to



17

00:01:18,990 --> 00:01:24,670

render this particular cell, say, call a function to say, is there a reservation for this date?



18

00:01:24,780 --> 00:01:26,040

If so, do something.



19

00:01:26,250 --> 00:01:32,070

And then if there's not called another function to say, is there a block for this date and if so,



20

00:01:32,070 --> 00:01:35,430

do something, and if not, just display an empty checkbox.



21

00:01:36,270 --> 00:01:43,080

But if you think that through, that would mean since there are 31 days in this month and two rooms,



22

00:01:43,260 --> 00:01:48,360

that's a total of 62 dates to check and two function calls on each of those dates.



23

00:01:48,510 --> 00:01:52,110

So that be two times, 31 times two, which is a big number.



24

00:01:52,110 --> 00:01:54,840

That's an awful lot of database queries to perform.



25

00:01:55,290 --> 00:01:56,930

And it's really not that efficient.



26

00:01:57,540 --> 00:02:03,180

It might be much more useful if we could get all of that information and stored in some data structure,



27

00:02:03,180 --> 00:02:09,750

say, a map, for example, and use that to determine how to render a given cell for a given date,



28

00:02:09,750 --> 00:02:10,590

for a given room.



29

00:02:10,980 --> 00:02:12,920

And I think that's a far more efficient method.



30

00:02:13,200 --> 00:02:14,660

So let's get started doing that.



31

00:02:15,210 --> 00:02:21,090

I'm going to go back here and I'm going to range through this room's variable that I have.



32

00:02:21,090 --> 00:02:25,260

So for and I'm going to ignore the index and just call the variable.



33

00:02:25,260 --> 00:02:28,590

I'm going to look at X range rooms.



34

00:02:29,790 --> 00:02:32,640

And inside of that I'm going to create two maps.



35

00:02:32,640 --> 00:02:40,020

And the very first map I'm going to create is for reservations and the next one will be for the actual



36

00:02:41,970 --> 00:02:42,480

blocks.



37

00:02:42,930 --> 00:02:46,170

So let's create two maps, create maps.



38

00:02:46,500 --> 00:02:55,380

The first one is going to be called reservation map and it will be assigned the value of make map string.



39

00:02:55,380 --> 00:03:00,780

And that's how we'll look it up and I'll just store in there and it and let's duplicate this line and



40

00:03:00,780 --> 00:03:02,220

create a block map.



41

00:03:05,660 --> 00:03:13,190

OK, so now that I have these created, how am I going to get the information for you in this map useful?



42

00:03:13,220 --> 00:03:18,110

Well, the first thing I need to do is make sure that there's one entry for every single day in the



43

00:03:18,110 --> 00:03:22,350

current month in both the reservation map and the block map.



44

00:03:22,370 --> 00:03:26,150

That means I need to somehow loop over all the days of the month.



45

00:03:26,180 --> 00:03:28,910

Well, if you recall, we already know what the first day of the month is.



46

00:03:28,910 --> 00:03:31,280

We have it here and we know what the last day of the month is.



47

00:03:31,280 --> 00:03:32,000

We have it here.



48

00:03:32,450 --> 00:03:38,900

So let's just do a for loop and we'll do this, not looping through INTs, but instead looping through



49

00:03:38,930 --> 00:03:40,600

dates, which we haven't done yet.



50

00:03:40,640 --> 00:03:41,440

But isn't that hurt?



51

00:03:42,170 --> 00:03:46,760

So for my variable will be called D, and that's going to be equal to the first of the month.



52

00:03:48,080 --> 00:03:52,330

And I want to go until I'm not after the last day of the month.



53

00:03:52,940 --> 00:04:00,380

So since it's a date, I can just say dot after and I can use my variable last of month if that's equal



54

00:04:00,380 --> 00:04:00,980

defaults.



55

00:04:01,370 --> 00:04:05,330

While that's while we're not after the last day of the month, keep going.



56

00:04:05,760 --> 00:04:10,100

And every time you iterate through the through the loop, add one to the current day.



57

00:04:11,120 --> 00:04:12,170

Didn't add date.



58

00:04:14,310 --> 00:04:21,780

Zero years, zero months and one day and what I'm going through, this just put a default value in in



59

00:04:21,780 --> 00:04:27,270

both the reservation map, reservation map for the current day.



60

00:04:27,270 --> 00:04:28,860

And I'm going to use this as a string.



61

00:04:28,890 --> 00:04:30,180

This is how we're going to look things up.



62

00:04:30,180 --> 00:04:38,100

So current is D format and my format string will be a four digit year, a two digit month and a one



63

00:04:38,100 --> 00:04:39,360

or two digit day.



64

00:04:39,780 --> 00:04:44,190

And that's going to be equal to zero, which will say this room is available and don't do the same thing



65

00:04:44,670 --> 00:04:45,570

for the block map.



66

00:04:47,580 --> 00:04:54,840

OK, so now I've initialized both of these reservation maps, each of these maps has an entry for every



67

00:04:54,840 --> 00:05:00,930

day of the current month and the value is zero and the lookup is a string.



68

00:05:00,930 --> 00:05:05,280

That would be the four digit year, followed by a hyphen, followed by a two digit month, followed



69

00:05:05,280 --> 00:05:09,050

by a hyphen followed by a one or two digit day.



70

00:05:09,990 --> 00:05:14,910

So that will be how we look things up, which is extremely convenient, because on this calendar, I



71

00:05:14,910 --> 00:05:16,530

know what the current year is.



72

00:05:16,530 --> 00:05:21,060

I have a value that I'm storing in the string map called current year, and I have another one for the



73

00:05:21,060 --> 00:05:27,660

current month so I can actually build the date as I'm iterating through my range.



74

00:05:27,660 --> 00:05:29,630

That gives me this table in the first place.



75

00:05:30,300 --> 00:05:31,680

So that's how we're going to look things up.



76

00:05:32,220 --> 00:05:40,710

Now that we have this done, we need next to get all the restrictions for the current ramp and that



77

00:05:40,710 --> 00:05:46,110

means we need a database function to do that and we don't have one that does that yet, but we can do



78

00:05:46,110 --> 00:05:47,430

it really, really easily.



79

00:05:48,480 --> 00:05:50,610

So let's go over to our postgrads Dongo.



80

00:05:51,270 --> 00:05:57,210

And at the very bottom of this file, I will create a new function, which I will call func.



81

00:05:57,210 --> 00:06:00,450

It'll have the receiver of Postgres DB Repo.



82

00:06:02,910 --> 00:06:11,390

And I'll call it get restrictions for room by day, and it will have to have three parameters.



83

00:06:11,400 --> 00:06:13,970

First of all, what room are we dealing with the remedy?



84

00:06:13,980 --> 00:06:19,740

And that's an end and then the start date we want to look at and the end date we want to look at, both



85

00:06:19,740 --> 00:06:21,720

of those will be of type time, time.



86

00:06:21,960 --> 00:06:26,490

And I'm going to return a slice of model's room restriction.



87

00:06:28,020 --> 00:06:29,190

And potentially an error.



88

00:06:30,260 --> 00:06:36,900

OK, so as I always do, I'm going to copy the context code so I don't have to retype it pasted in here.



89

00:06:37,410 --> 00:06:38,720

And now we need to write the query.



90

00:06:38,970 --> 00:06:41,010

Well, we need some to store the information first.



91

00:06:41,010 --> 00:06:47,810

So let's create a variable called restrictions of type slice models, dot room restriction.



92

00:06:49,050 --> 00:06:50,210

And now let's write our query.



93

00:06:50,220 --> 00:06:51,780

And this is a really easy query.



94

00:06:51,810 --> 00:06:59,040

It's pretty much the same syntax that we've used for other lookups or queries that deal with the reservations



95

00:06:59,040 --> 00:07:01,760

and blocks and so forth, availability queries, in other words.



96

00:07:02,340 --> 00:07:07,500

So I'm going to select I will select ID and then I need the reservation ID.



97

00:07:10,330 --> 00:07:16,080

If it exists and it might be null and I'm going to talk about that in a moment, and we need the restriction



98

00:07:16,090 --> 00:07:24,280

ID and we need the remedy and we need the start date and we need the end date and we're going to get



99

00:07:24,280 --> 00:07:27,250

all of that from room restrictions.



100

00:07:29,640 --> 00:07:37,710

Where and this is the same logic we used before, so our start date is less than the end date and our



101

00:07:37,860 --> 00:07:41,280

end date is greater than or equal to the start date.



102

00:07:44,560 --> 00:07:48,800

And the remedy is equal to whatever we're passing it.



103

00:07:48,850 --> 00:07:49,600

So that's our query.



104

00:07:50,380 --> 00:07:53,770

OK, now let's get our Rose.



105

00:07:53,890 --> 00:08:04,840

Rose Air is a sign the value of IMDB dot query context handed the context and did our query, handed



106

00:08:04,840 --> 00:08:08,170

our start, handed our end and our remedy.



107

00:08:10,480 --> 00:08:18,350

If error is not equal to nil, then just return nil and the error otherwise answer it.



108

00:08:19,030 --> 00:08:20,770

So we've got to defer our rose close here.



109

00:08:25,910 --> 00:08:28,130

And for Rose next.



110

00:08:30,020 --> 00:08:36,680

We create an empty variable to hold the restrictions of our hour is of type models, room restriction.



111

00:08:38,970 --> 00:08:46,980

And scan error is a sign the value of rose dot scan and will scan into that variable we just created



112

00:08:47,430 --> 00:08:53,490

and we're going to put in to the variable error ID and I'll just duplicate this a few times, as I usually



113

00:08:53,490 --> 00:08:53,840

do.



114

00:08:54,540 --> 00:08:56,740

And our second value was the reservation ID.



115

00:08:56,760 --> 00:08:59,690

Now that might be a problem and I'll talk about that in a moment.



116

00:09:01,200 --> 00:09:05,790

And the restriction ID and the remedy.



117

00:09:07,600 --> 00:09:11,320

And the start date and the Endi.



118

00:09:14,020 --> 00:09:22,330

OK, so here's the problem, if you think about what's in the room restrictions table, we don't always



119

00:09:22,330 --> 00:09:23,860

have a value for reservation.



120

00:09:24,700 --> 00:09:28,980

So let me go look at post code and show you what I'm talking about.



121

00:09:28,990 --> 00:09:33,940

So make sure I'm on the right database, go to bookings, look at room restrictions.



122

00:09:34,420 --> 00:09:38,200

And here we have room restrictions.



123

00:09:41,330 --> 00:09:42,170

It's not the right one.



124

00:09:43,100 --> 00:09:50,450

Yes, it is reservation, if you look at this, all of these ones have a null for a value and they should



125

00:09:50,450 --> 00:09:53,050

because they're blocks, they're not actual reservations.



126

00:09:53,090 --> 00:09:59,690

Those are dates and rooms where the property owner has decided not to rent the room for that particular



127

00:09:59,690 --> 00:10:00,310

date range.



128

00:10:00,500 --> 00:10:08,240

So they're all null it back here in my query when I try to get reservation ID, if it's in.



129

00:10:08,240 --> 00:10:14,570

No, I'm trying to store a null value into this very this field of this variable reservation ID of the



130

00:10:14,570 --> 00:10:19,970

variable hour, which is of type models, room restriction and go will not let you do that because a



131

00:10:19,970 --> 00:10:22,940

null is not an int and it wants an int.



132

00:10:23,930 --> 00:10:29,240

So I need to make some determination as to what to do with that null value.



133

00:10:29,270 --> 00:10:30,760

Unfortunately it's really, really easy.



134

00:10:30,770 --> 00:10:32,060

There's a couple of ways of doing it.



135

00:10:32,330 --> 00:10:38,330

Go has a null int type that I can use, but I find that a real pain and tend to avoid it whenever I



136

00:10:38,330 --> 00:10:39,150

possibly can.



137

00:10:39,290 --> 00:10:41,210

I find this approach works really well.



138

00:10:41,510 --> 00:10:44,270

I use one of the built-In features that's available in sequel.



139

00:10:44,270 --> 00:10:45,260

It's called Coalesce.



140

00:10:47,350 --> 00:10:48,370

And what I'm going to do.



141

00:10:50,180 --> 00:10:53,290

Is change my query as follows?



142

00:10:56,560 --> 00:11:03,900

I say, if reservation ID has a value and that value is not null, use it, otherwise use zero.



143

00:11:04,210 --> 00:11:09,430

And that's perfect for my purposes because I can store zero, which is an entry down here.



144

00:11:09,430 --> 00:11:10,110

No problem.



145

00:11:10,540 --> 00:11:12,700

And if it has, he actually has a reservation.



146

00:11:12,700 --> 00:11:17,000

I'll store the ID for that reservation instead and that solves my problem.



147

00:11:17,680 --> 00:11:18,150

All right.



148

00:11:18,160 --> 00:11:19,500

So let's check for an error.



149

00:11:20,100 --> 00:11:23,380

I'll just copy this if areacode paste it here.



150

00:11:23,560 --> 00:11:27,850

If there is no error, I will take, which is are not error.



151

00:11:32,230 --> 00:11:40,150

If I get past that, there's no air, so I can just say restrictions equals append restrictions and



152

00:11:40,150 --> 00:11:40,390

earn.



153

00:11:42,090 --> 00:11:46,830

And that will take care of that and then, of course, as I always do, I'll check to make sure one



154

00:11:46,830 --> 00:11:49,620

last time if error is equal to.



155

00:11:50,990 --> 00:11:53,390

If error equals Rove's error.



156

00:11:55,910 --> 00:11:57,820

And air is not equal to nil.



157

00:11:58,370 --> 00:12:06,950

Then something went wrong, so I'll just return nil and error, otherwise return the data that we just



158

00:12:06,950 --> 00:12:10,700

got, return restrictions and nil.



159

00:12:11,480 --> 00:12:13,420

OK, so I've created this.



160

00:12:13,430 --> 00:12:18,200

Let's give it its comment as it should have, and then add it to the repository and added to our DNA



161

00:12:18,800 --> 00:12:25,940

testing be rebuilt returns, restrictions



162

00:12:28,790 --> 00:12:31,400

for a room by date range.



163

00:12:32,900 --> 00:12:34,190

And let's copy the whole thing.



164

00:12:37,230 --> 00:12:38,730

And open up our test repo.



165

00:12:41,740 --> 00:12:44,220

And paste it in here and make it as simple as possible.



166

00:12:48,580 --> 00:12:50,350

So our application will compile.



167

00:12:53,030 --> 00:12:54,290

Give it the correct receiver.



168

00:12:56,860 --> 00:13:01,090

And now add this entire string to a repository.



169

00:13:02,920 --> 00:13:03,940

Right here.



170

00:13:05,070 --> 00:13:10,600

OK, let's make sure the application compiles so we don't have any typos anywhere and we have X to clear



171

00:13:10,600 --> 00:13:11,350

but not used.



172

00:13:11,380 --> 00:13:17,320

OK, so that's to be expected because we haven't actually done anything with that X yet.



173

00:13:17,320 --> 00:13:20,200

So let's get our restrictions.



174

00:13:20,470 --> 00:13:30,070

Restrictions and potentially an error are equal to IMDB dot get restrictions for room by date are variable



175

00:13:30,070 --> 00:13:32,350

called X, so we get a remedy from X.



176

00:13:32,950 --> 00:13:39,400

We want all the restrictions for this room for the current month so we can use our first month as our



177

00:13:39,400 --> 00:13:42,220

start and our last month as the end.



178

00:13:42,250 --> 00:13:47,950

And that will get me all of the restrictions for this room for the current month, which is exactly



179

00:13:47,950 --> 00:13:48,920

what I need.



180

00:13:49,480 --> 00:13:50,590

So we've got a check for an error.



181

00:13:50,590 --> 00:13:57,760

If error is not equal to nil, we'll just say helper's dot server error W and the error and return.



182

00:13:58,090 --> 00:14:00,950

Otherwise we can now do something with our restrictions.



183

00:14:01,660 --> 00:14:07,750

So what we're going to do is loop through those restrictions one at a time and determine whether it's



184

00:14:07,750 --> 00:14:09,820

a reservation or it's a block.



185

00:14:09,820 --> 00:14:15,070

If it's a reservation, we'll put the appropriate entry in our reservation map if it's a block will



186

00:14:15,070 --> 00:14:17,160

put the appropriate entry in our block map.



187

00:14:18,070 --> 00:14:23,470

So this is pretty straightforward for underscore or ignore the index and I'll use Y, which is a variable



188

00:14:23,470 --> 00:14:26,980

I've not used yet that's going to range through restrictions.



189

00:14:29,390 --> 00:14:32,250

And we just checked to see is it a reservation?



190

00:14:32,330 --> 00:14:33,850

How do I know it's a reservation?



191

00:14:34,100 --> 00:14:39,430

If reservation ID is greater than zero than it's a reservation, otherwise it's a block.



192

00:14:39,620 --> 00:14:45,860

So if we got DOT reservation, it is greater than zero.



193

00:14:47,060 --> 00:14:50,420

It's a reservation otherwise.



194

00:14:52,570 --> 00:15:00,220

It's a block, so reservations can be one day long or they can be ninety nine days long, so we need



195

00:15:00,220 --> 00:15:07,120

to actually loop through the dates for the current reservation and put one entry for each of the dates



196

00:15:07,630 --> 00:15:09,070

into our reservation map.



197

00:15:09,090 --> 00:15:10,280

Unfortunately, that's pretty easy.



198

00:15:10,300 --> 00:15:18,970

We can use exactly the same logic we did up here for D is assigned the value of and the the first index



199

00:15:18,970 --> 00:15:20,770

will be the reservation start date.



200

00:15:21,550 --> 00:15:26,440

So we're going to start at the start date and we want to go until we're not after.



201

00:15:26,920 --> 00:15:34,900

It's not D it's a yes it is after until we're after the end date for the reservation that has to be



202

00:15:34,900 --> 00:15:37,000

equal to faults in order to keep going through the loop.



203

00:15:37,270 --> 00:15:39,370

And we need to add one to the date.



204

00:15:39,370 --> 00:15:42,160

D is equal to dot add date.



205

00:15:43,540 --> 00:15:48,190

No years, no months one day and we're going to loop through that.



206

00:15:48,370 --> 00:15:50,200

So get our parentheses in there.



207

00:15:50,680 --> 00:15:53,650

And what we're going to do is put a value in the reservation map.



208

00:15:53,650 --> 00:16:01,810

So reservation map and here we need to actually build the string appropriately and we're just going



209

00:16:01,810 --> 00:16:04,150

to use the same format we did up here.



210

00:16:04,480 --> 00:16:11,260

DOT format and the layout will be a four digit year, a two digit month and a one or two digit digit



211

00:16:11,260 --> 00:16:11,680

day.



212

00:16:12,490 --> 00:16:15,280

And we don't want that to be equal to zero or one.



213

00:16:15,280 --> 00:16:21,160

We need it to be equal to the reservation ID, reservation ID.



214

00:16:21,610 --> 00:16:28,990

So now our map will have for all of the days of the current reservation and entry that is equal to the



215

00:16:28,990 --> 00:16:32,790

date that the rise that we're dealing with and the reservation ID.



216

00:16:32,830 --> 00:16:35,900

And we can use that to build a link to the reservation in our map.



217

00:16:37,450 --> 00:16:39,970

Now if it's a block, it's even easier.



218

00:16:40,060 --> 00:16:43,510

We just need to put because all blocks are one day long, we can just say block map.



219

00:16:46,260 --> 00:16:49,590

Not or why not start date?



220

00:16:52,330 --> 00:17:00,370

That format and used the same syntax, zero, one two, and that will be equal to and we'll put in the



221

00:17:00,370 --> 00:17:01,120

restriction in.



222

00:17:05,640 --> 00:17:12,210

So that gives me the actual restriction ID itself, the one that I can use to link to the restriction



223

00:17:12,210 --> 00:17:14,260

that I need to close, and that's pretty straightforward.



224

00:17:14,670 --> 00:17:21,150

So as long as it's not zero and it won't be zero, this will be a restriction, a block for that current



225

00:17:21,150 --> 00:17:21,420

date.



226

00:17:22,650 --> 00:17:25,760

So now I have these things built after this for loop is finished.



227

00:17:25,770 --> 00:17:26,910

What am I going to do with them?



228

00:17:26,940 --> 00:17:32,190

Well, I need to put them somewhere so I can pull them out in the template and use them as I need to.



229

00:17:32,200 --> 00:17:33,190

And that's pretty straightforward.



230

00:17:33,390 --> 00:17:39,600

We use our data variable data and I'll give it a look up and I want to be able to look it up for an



231

00:17:39,600 --> 00:17:43,620

individual room, both the reservation map and the block map.



232

00:17:43,620 --> 00:17:47,580

So I'll just give it a meaningful name using format dot as print f.



233

00:17:50,630 --> 00:17:57,830

And I'll call it reservation map, underscore, map, underscore and present deals, and I'll replace



234

00:17:57,830 --> 00:17:59,890

that with the idea of the room.



235

00:18:00,740 --> 00:18:02,920

So that will be Eckstut ID.



236

00:18:04,890 --> 00:18:11,430

And that's going to be equal to my reservation man, and I'll duplicate this and change this to block.



237

00:18:15,220 --> 00:18:23,140

And then I'll store the block map in there, so that gives me one reservation map for every room and



238

00:18:23,140 --> 00:18:30,850

one block map for every room, and the reservation map will have an empty default values of zero if



239

00:18:30,850 --> 00:18:36,970

there is no reservation for for a given day or will have the ID of the reservation for a given day if



240

00:18:36,970 --> 00:18:37,660

one exists.



241

00:18:37,660 --> 00:18:43,500

And the same thing with a block map zero if there's no block and the ID of the block if it does exist.



242

00:18:43,900 --> 00:18:45,520

Now, there's one other thing I'm going to do here.



243

00:18:45,700 --> 00:18:52,160

I'm actually going to store the block map for this room in this session and I'm going to do that for



244

00:18:52,160 --> 00:18:54,130

a reason which may not be immediately apparent.



245

00:18:54,130 --> 00:18:56,140

But let's get it in there and then I'll tell you why I'm doing it.



246

00:18:56,830 --> 00:18:59,320

Amde App Session put.



247

00:19:01,260 --> 00:19:12,180

Our context and I will call this format formatter, sprint f block, underscore, map, underscore D



248

00:19:13,800 --> 00:19:19,500

ID for the substitution and I'm going to store in the block map the current block map for the current



249

00:19:19,500 --> 00:19:19,760

round.



250

00:19:19,770 --> 00:19:24,780

So there will be one entry put in the session for every room that I'm dealing with.



251

00:19:24,780 --> 00:19:27,290

So there'll be two to put in here every time I come through.



252

00:19:27,840 --> 00:19:32,750

And this is important and the reason it's important is not immediately apparent, but will be shortly.



253

00:19:32,760 --> 00:19:35,220

Let me give you the the short version of it.



254

00:19:36,810 --> 00:19:45,180

When the map is when the calendar is first rendered to the screen, I need to store the block map as



255

00:19:45,180 --> 00:19:51,510

it existed at the moment it was rendered and before the user does anything to the reservation calendar.



256

00:19:51,870 --> 00:19:58,350

And the reason is once they post that, my post handler will pull this map out of the session and use



257

00:19:58,350 --> 00:20:02,340

that to compare what we currently have with what we used to have.



258

00:20:02,670 --> 00:20:08,070

So I'll be able to determine things like which blocks am I getting rid of and which ones are new.



259

00:20:08,070 --> 00:20:10,680

And I need to have this information in order to do that.



260

00:20:10,950 --> 00:20:17,310

And the other thing to bear in mind is I just put a map of type string int into the session, but I



261

00:20:17,310 --> 00:20:21,470

haven't actually told my application that I'm going to be storing things like that in the session.



262

00:20:21,690 --> 00:20:28,320

So let's open our mango and do that ghab register right here in the run function on mango.



263

00:20:28,500 --> 00:20:33,930

I need to register a type of map string.



264

00:20:36,150 --> 00:20:36,570

Int.



265

00:20:39,490 --> 00:20:45,760

There, so I've now got this information, let's make sure everything renders the way our runs the way



266

00:20:45,760 --> 00:20:46,130

it should.



267

00:20:46,150 --> 00:20:48,100

So let's try compiling the application.



268

00:20:50,800 --> 00:20:56,170

Let's go back to our screen here and make sure everything works, so look at new reservations and now



269

00:20:56,170 --> 00:20:57,490

look at our reservation calendar.



270

00:20:57,490 --> 00:20:57,990

Perfect.



271

00:20:58,530 --> 00:21:06,040

So at this moment, I have everything I need a pass to my template in one form or another in order to



272

00:21:06,040 --> 00:21:09,250

be able to render the dates appropriately.



273

00:21:09,970 --> 00:21:10,470

I think I do.



274

00:21:10,480 --> 00:21:11,450

Anyway, let's go make sure.



275

00:21:11,740 --> 00:21:13,330

So back in my template.



276

00:21:15,630 --> 00:21:19,500

I'm going to look and make sure that I'm pulling everything out of there, I have the current date,



277

00:21:19,650 --> 00:21:22,470

I have the current rims, I know the days in the month.



278

00:21:22,860 --> 00:21:26,660

Now, there's two other pieces of information that I stored that I need to get here as well.



279

00:21:26,670 --> 00:21:30,210

So let's go back to our handlers and have a look here.



280

00:21:30,960 --> 00:21:34,020

So I stored at some point in the string.



281

00:21:34,020 --> 00:21:40,740

Yes, here I have this month and this year, which I need to be able to have access to in the next lecture.



282

00:21:40,740 --> 00:21:42,360

So let's grab that information right now.



283

00:21:42,550 --> 00:21:45,030

So let's go back here and say.



284

00:21:47,430 --> 00:21:52,150

Per month is a sign the value of index dot, string map.



285

00:21:52,590 --> 00:21:54,600

And what did I call it back in my handlers?



286

00:21:55,500 --> 00:21:57,000

I called it this month.



287

00:22:00,050 --> 00:22:08,510

And then I'll duplicate this line year and Curre year and let's make sure that that still renders appropriately



288

00:22:08,540 --> 00:22:09,510

reservation calendar.



289

00:22:09,530 --> 00:22:10,160

Yes, it does.



290

00:22:10,490 --> 00:22:15,590

OK, so at this point, I know that I have everything I need pass to this template.



291

00:22:15,800 --> 00:22:22,340

I have a total of four maps with respect to restrictions, a block map for generals quarters, a block



292

00:22:22,340 --> 00:22:23,480

map for major suite.



293

00:22:23,690 --> 00:22:28,220

I have a reservation map for generals quarters and a reservation map for four major suite.



294

00:22:28,490 --> 00:22:31,140

And I know the current month and I know the current year.



295

00:22:31,550 --> 00:22:36,860

So this is all the information I need in order to render the information on the screen.



296

00:22:36,860 --> 00:22:39,470

And that's what we'll take care of in the next lecture.
