1 00:00:01,650 --> 00:00:08,070 So now we want to make the world we built on this button, which goes to Bucaram and then pass some 2 00:00:08,070 --> 00:00:12,390 parameters, it passes the RIM ID, the start date and the end date. 3 00:00:12,690 --> 00:00:19,140 We need to set up a handler that takes that and then creates a special variable for a reservation stores 4 00:00:19,140 --> 00:00:22,440 that in the session and then takes us to the reservation page. 5 00:00:22,450 --> 00:00:23,240 And that's really easy. 6 00:00:23,250 --> 00:00:23,930 Let's do it now. 7 00:00:25,260 --> 00:00:31,980 So let's go over to our roots and create a room and we'll call this room. 8 00:00:32,160 --> 00:00:34,820 It'll be a get request or I'll just duplicate the previous line. 9 00:00:35,370 --> 00:00:38,970 It will be a get request to book Dasch room. 10 00:00:38,970 --> 00:00:44,100 And it's going to take us to a handler called Book Room, which doesn't exist yet, but we can go create 11 00:00:44,100 --> 00:00:44,290 that. 12 00:00:45,480 --> 00:00:53,550 So here in my handlers, let's create a function which will take the repository as a receiver and we'll 13 00:00:53,550 --> 00:00:54,720 call it book room. 14 00:00:55,320 --> 00:01:02,160 And as is the case with every handler, it has to have a response writer, which is a response writer. 15 00:01:04,380 --> 00:01:05,760 And a pointer to a request. 16 00:01:10,780 --> 00:01:15,880 All right, so that should fix the error in our rights file, and it does and what are we going to get 17 00:01:15,880 --> 00:01:16,060 here? 18 00:01:16,090 --> 00:01:19,240 Well, we're going to have to grab the values from the euro. 19 00:01:19,250 --> 00:01:29,860 And I know those are stored in parameters called ID s and E, so let's get the ID is equal to ideate 20 00:01:29,860 --> 00:01:31,670 an error because I'm actually going to. 21 00:01:33,470 --> 00:01:38,360 I have to pass it from a string to an end, and again, I'm just going to ignore the air for now is 22 00:01:38,360 --> 00:01:45,440 equal to our URL query doGet and on the name of the parameter, which is Edet. 23 00:01:46,670 --> 00:01:49,800 And of course, I want to convert that from a string to an end. 24 00:01:49,820 --> 00:01:59,210 So Pesters Seo Astar Seo in the dot a twohy and we'll put the parameter, the parentheses where they 25 00:01:59,210 --> 00:02:10,730 belong and now have the ID and will say the start date is equal to our new URL dot query douget which 26 00:02:10,730 --> 00:02:12,890 allows me to get a parameter, a get parameter. 27 00:02:13,070 --> 00:02:14,320 And this one is called S. 28 00:02:16,510 --> 00:02:17,410 And ending. 29 00:02:20,370 --> 00:02:28,770 This is a sign the value of our UFO query does not get E for end, and I'm pretty sure that's what I 30 00:02:28,770 --> 00:02:29,150 called them. 31 00:02:29,160 --> 00:02:30,020 Let's go make sure. 32 00:02:30,030 --> 00:02:34,900 So it's in the general's page s e and ID. 33 00:02:34,920 --> 00:02:36,500 Yes, that's exactly what I've called them. 34 00:02:36,690 --> 00:02:43,440 Now, just to make sure this works, before we go any further, let's just log this log print line D, 35 00:02:43,800 --> 00:02:47,800 which is uppercase ID, start date and end date. 36 00:02:48,420 --> 00:02:49,530 Let's make sure that works. 37 00:02:49,530 --> 00:02:52,440 So I'm going to start my application. 38 00:02:53,640 --> 00:02:54,690 Run my application. 39 00:02:56,720 --> 00:03:03,440 And I expect to see printed out right here in the terminal those three parameters once I click on this 40 00:03:03,440 --> 00:03:07,070 link, which fortunately I left active, so I should be able to just click on it. 41 00:03:08,420 --> 00:03:12,420 Page not found book dash room ID. 42 00:03:12,860 --> 00:03:13,690 I got something wrong. 43 00:03:13,700 --> 00:03:14,930 Let's go find out what's in the roots. 44 00:03:16,340 --> 00:03:18,860 Sagbo might want to spell room. 45 00:03:18,860 --> 00:03:19,190 Right. 46 00:03:19,220 --> 00:03:20,270 So let's start that over. 47 00:03:24,800 --> 00:03:31,340 And come back here and I should be able to just hit this hit, click in here and hit return, and I 48 00:03:31,340 --> 00:03:32,840 got a blank screen that's promising. 49 00:03:33,600 --> 00:03:38,470 Let's go back to our terminal and there is the ID, the start date and the end date. 50 00:03:38,480 --> 00:03:38,810 Good. 51 00:03:38,820 --> 00:03:41,000 So I know that you are out now. 52 00:03:41,000 --> 00:03:41,470 Works. 53 00:03:41,480 --> 00:03:42,650 Now, what am I going to do with this? 54 00:03:43,190 --> 00:03:44,240 Well, think about what we do. 55 00:03:44,240 --> 00:03:51,670 Let's see when we after we choose a room, when we post book, when we post make a reservation. 56 00:03:51,770 --> 00:03:56,750 It's at this point just before we display the make reservation page, we need to have some information. 57 00:03:56,760 --> 00:03:58,000 So let's go in there and see what we have. 58 00:03:58,460 --> 00:04:02,310 We have to have a sessional variable that is a reservation. 59 00:04:02,330 --> 00:04:05,960 OK, so I'm going to want to create a reservation and put it in the session. 60 00:04:06,260 --> 00:04:09,180 And that has to have some information. 61 00:04:09,350 --> 00:04:16,730 It has to have the start date, the end date, the room ID and the room name so we can do that. 62 00:04:16,820 --> 00:04:17,480 That's not hard. 63 00:04:17,510 --> 00:04:20,120 So let's go down here and get our room. 64 00:04:21,200 --> 00:04:23,090 First of all, let's create a variable call. 65 00:04:23,090 --> 00:04:27,800 A ver rez is of type models, dot reservation. 66 00:04:28,390 --> 00:04:33,790 Now I have an empty reservation so I can assign some things there right away and I need to put in red 67 00:04:33,920 --> 00:04:35,660 dot remedy. 68 00:04:36,050 --> 00:04:36,800 I have that. 69 00:04:37,010 --> 00:04:41,270 That's just the ID, which maybe I'll call remedy, just make it more readable. 70 00:04:41,450 --> 00:04:45,770 Room ID is equal to remedy. 71 00:04:47,030 --> 00:04:48,920 Then I need to put it in the start date in the end date. 72 00:04:48,980 --> 00:04:54,380 But remember the start date in the end date are actually in the format of time dot time. 73 00:04:54,380 --> 00:04:58,550 And we have lots of examples up here where we did precisely that. 74 00:04:58,550 --> 00:05:07,740 So let's just copy these, copy these three lines and come down here and we'll do that right here. 75 00:05:08,420 --> 00:05:14,180 So this expects the spring to the string to be called SD, so I'll just rename this to rename this to 76 00:05:14,180 --> 00:05:14,660 Eddie. 77 00:05:14,660 --> 00:05:18,350 And now I have them in the correct format, which means I can go resort. 78 00:05:18,350 --> 00:05:25,250 Start date is equal to start date and end date is equal to ending. 79 00:05:26,120 --> 00:05:28,790 So I have the remedy, the start date and the end date. 80 00:05:28,970 --> 00:05:29,950 What else do I need? 81 00:05:29,960 --> 00:05:35,030 The last piece of information I need is the room name, which we did up here. 82 00:05:35,030 --> 00:05:38,840 So we can just find that where we did it and copy it, paste it and we'll be good to go. 83 00:05:39,350 --> 00:05:41,480 So let's see where we did it up here. 84 00:05:47,370 --> 00:05:48,570 Which is fine room name. 85 00:05:51,350 --> 00:05:55,040 Right here, so we can copy these lines. 86 00:05:57,250 --> 00:06:02,140 Try that again, kopi these lines and pasted them down here. 87 00:06:07,820 --> 00:06:16,310 So rez remedies should just be remedy that gives me my room and then rez room, the room name equals 88 00:06:16,310 --> 00:06:17,090 room room name. 89 00:06:17,120 --> 00:06:22,610 So at this point I've built up my variable, my special variable, the variable that's going to be put 90 00:06:22,610 --> 00:06:23,360 into the session. 91 00:06:23,390 --> 00:06:31,280 So let's just stick it in session m dot app, dot session dot put and it needs the context arg context, 92 00:06:32,780 --> 00:06:36,790 the name which needs to be reservation because that's what I'm expecting to pull out. 93 00:06:36,800 --> 00:06:39,170 Is it by that key and then there is. 94 00:06:40,160 --> 00:06:40,490 All right. 95 00:06:40,520 --> 00:06:41,720 So now we've got this done. 96 00:06:41,720 --> 00:06:42,960 What do we want to do next. 97 00:06:42,980 --> 00:06:48,380 We want to take them to the make reservation page HGP redirect. 98 00:06:49,910 --> 00:06:50,570 Try that again. 99 00:06:51,170 --> 00:06:57,830 Redirect and that expects to have w r make Dasch reservation. 100 00:07:00,400 --> 00:07:09,190 And the actual code, which will be HDB status, temporary redirect, no less of status will go with 101 00:07:09,190 --> 00:07:09,520 that one. 102 00:07:09,610 --> 00:07:10,630 OK, and that should be it. 103 00:07:10,880 --> 00:07:12,310 That's should be all I have to do. 104 00:07:12,310 --> 00:07:15,370 So I'll get rid of this comment because I'm not using it. 105 00:07:16,330 --> 00:07:18,850 And I'll give this the comment it should have. 106 00:07:20,350 --> 00:07:27,070 I probably have some other ones I have to comment to so I'm able to do that, takes your parameters, 107 00:07:29,680 --> 00:07:38,020 builds a sessional variable and takes user to make res screen. 108 00:07:38,870 --> 00:07:40,500 OK, so that one has its comment. 109 00:07:41,080 --> 00:07:42,180 This one needs a comment. 110 00:07:42,700 --> 00:07:43,990 What does Chew's room do. 111 00:07:45,880 --> 00:07:50,860 Displays list of available rooms. 112 00:07:51,430 --> 00:07:56,050 OK, reservation summary needs a comment because I'm getting sloppy in my old age. 113 00:07:57,010 --> 00:08:03,190 Display's the reservation summary page summary has to Ms. 114 00:08:05,280 --> 00:08:11,900 And reservation doesn't have an extra eye, and I think that should be it looks like the rest of them, 115 00:08:12,150 --> 00:08:13,490 that one doesn't need a comment. 116 00:08:14,160 --> 00:08:15,170 This one does the rest. 117 00:08:15,210 --> 00:08:15,390 Good. 118 00:08:15,420 --> 00:08:15,870 All right. 119 00:08:16,200 --> 00:08:17,610 So let's stop our application. 120 00:08:20,810 --> 00:08:26,260 Started go back to a Web browser and let's start over, so we'll start at localhost right from the beginning 121 00:08:27,860 --> 00:08:31,850 and I'll hide the JavaScript console because I'm pretty sure there's no JavaScript errors. 122 00:08:31,880 --> 00:08:33,890 Now, I want to go to the rooms page. 123 00:08:33,890 --> 00:08:35,810 The only one that set up is generals quarters. 124 00:08:35,810 --> 00:08:42,050 We'll have to do a major suite next and check availability and search for dates I know are available 125 00:08:42,050 --> 00:08:44,420 sometime in February, the ninth to the 10th. 126 00:08:44,940 --> 00:08:51,390 OK, room is available and hopefully this will take us to the reservation page and it does Generals' 127 00:08:51,410 --> 00:08:53,180 quarters, the ninth, the 10th. 128 00:08:53,180 --> 00:08:54,280 We're all set. 129 00:08:54,290 --> 00:08:59,360 And at this point I know that everything is right because otherwise this page wouldn't be displaying 130 00:08:59,360 --> 00:08:59,690 anything. 131 00:08:59,960 --> 00:09:01,510 So we should be good to go. 132 00:09:01,850 --> 00:09:09,710 So the last step at this point is to take the code that we've used for the generals quarters page and 133 00:09:09,710 --> 00:09:12,750 duplicate that functionality on the major sweep page. 134 00:09:13,250 --> 00:09:16,420 So really, that's just a copy and paste exercise. 135 00:09:16,430 --> 00:09:20,060 The one thing you have to remember to change is the remedy. 136 00:09:20,060 --> 00:09:24,010 And the remedy for major suite in my case is to. 137 00:09:24,320 --> 00:09:30,230 So I'll leave that as an exercise for you and then I'll go through I'll do it myself off camera and 138 00:09:30,500 --> 00:09:32,420 show you what I have in the next lecture. 139 00:09:32,420 --> 00:09:34,280 And then we're ready to move on to the next section.
