1 00:00:00,210 --> 00:00:01,770 Hello and welcome back. 2 00:00:02,160 --> 00:00:08,010 In this session, I will discuss about that Class-Based view, that means before we knew any peace, 3 00:00:08,010 --> 00:00:09,840 we use it by the function. 4 00:00:10,110 --> 00:00:12,570 So now you can also view it by the class. 5 00:00:12,570 --> 00:00:14,120 So how can do that work? 6 00:00:14,130 --> 00:00:17,430 In this video, I will show you that things with the live example. 7 00:00:17,760 --> 00:00:22,650 So for doing this, I want to do I want to open our first project where I have already discussed about 8 00:00:22,650 --> 00:00:26,250 how to create one of the court application with using that my skill. 9 00:00:26,490 --> 00:00:26,840 Right. 10 00:00:27,060 --> 00:00:33,510 So now better able to do and open out this project, not this one I just knew file open and now go to 11 00:00:33,510 --> 00:00:37,440 our project up in the exercise file into the exercise file. 12 00:00:37,440 --> 00:00:39,480 I have created one of the court application. 13 00:00:39,480 --> 00:00:42,840 We now are Jianguo back this right into the general practice. 14 00:00:42,840 --> 00:00:45,000 So that is all my first project to know. 15 00:00:45,000 --> 00:00:48,840 I want to open it so just simply because I select a folder. 16 00:00:49,890 --> 00:00:54,950 So that is our Fuseproject, and here I have already discussed about that with you, how can create 17 00:00:54,960 --> 00:00:57,380 under the court application with using the database? 18 00:00:57,780 --> 00:00:59,480 So right now we don't need this. 19 00:00:59,490 --> 00:01:01,560 I just simply remove everything from here. 20 00:01:02,050 --> 00:01:07,400 OK, the simply problem with everything and also here, we don't need this. 21 00:01:08,070 --> 00:01:10,820 So that is our second project right now. 22 00:01:10,830 --> 00:01:12,680 I just simply remove our second project. 23 00:01:12,900 --> 00:01:16,160 So for the first project, I have also created one of the database. 24 00:01:16,170 --> 00:01:16,600 Right. 25 00:01:16,650 --> 00:01:22,590 So if you go to PSU admin, make sure, first of all, you have to run your apogee and the my skill. 26 00:01:23,220 --> 00:01:28,320 So I have already done my Apache and the my skill and for the reason I say can actually access our database. 27 00:01:28,330 --> 00:01:31,740 So I have already created one of the database as my first Jianguo. 28 00:01:32,070 --> 00:01:37,130 Now if you run our server like that is our project as a fast project. 29 00:01:37,980 --> 00:01:45,390 So in particular that folder, that was my first project and here I ran our Sarovar as a pie and that 30 00:01:45,390 --> 00:01:48,410 man is not pie and then run server. 31 00:01:49,740 --> 00:01:57,000 So now that is actually our you are to say to simply copy it and go to our side and here I just run 32 00:01:57,000 --> 00:01:57,240 it. 33 00:01:58,500 --> 00:02:02,940 So very consistent, I have already discussed about that things with you from here, if you want to 34 00:02:02,940 --> 00:02:05,400 add any musician, you can add it. 35 00:02:05,400 --> 00:02:08,750 If you want to add any album, then you can add any album. 36 00:02:09,030 --> 00:02:12,960 And that is our album, all the data if you want to edit it right. 37 00:02:12,960 --> 00:02:15,270 If you want to read this data, you can edit it. 38 00:02:15,540 --> 00:02:19,020 And also if you want to direct this data, you can direct it from here. 39 00:02:19,530 --> 00:02:24,570 So we have done everything with you, seeing that our function in our view, like right now, I want 40 00:02:24,570 --> 00:02:27,230 to add some of the musicians. 41 00:02:28,380 --> 00:02:33,630 I just simply defend that name as the be for this purpose. 42 00:02:33,630 --> 00:02:34,940 Actually, this data will be needed. 43 00:02:34,950 --> 00:02:38,860 So for now, I just add some of the musicians because they were musicians. 44 00:02:39,240 --> 00:02:46,740 So here, if you want to add some of the album as a B and they name it as A and then I just defined 45 00:02:46,800 --> 00:02:51,720 on the date and also defined as a good click at the album. 46 00:02:51,990 --> 00:02:52,890 Now go here. 47 00:02:52,890 --> 00:02:54,020 You can see album is added. 48 00:02:54,450 --> 00:02:58,410 We have already done everything and every data is comes from our database. 49 00:02:58,410 --> 00:03:02,880 That means here I have already created of the database if you go to that musician. 50 00:03:04,680 --> 00:03:09,330 And you can see that is actually the new data is perfectly inserted in our database area, so now we 51 00:03:09,330 --> 00:03:12,770 will do the same things, we will do the same things with using that. 52 00:03:12,770 --> 00:03:16,850 Plus, like if you go to The View piece right now, we don't need this. 53 00:03:17,100 --> 00:03:22,970 If you go to that view here, you can see I have declared all that our function that is our index function. 54 00:03:22,980 --> 00:03:28,260 And here I have created another function of the album list and also I have created another function 55 00:03:28,260 --> 00:03:29,320 as a musician form. 56 00:03:29,760 --> 00:03:33,900 So now we will do the same things with using that our Class-Based view. 57 00:03:33,940 --> 00:03:35,230 So how can do that work? 58 00:03:35,250 --> 00:03:35,880 I'll show you. 59 00:03:35,880 --> 00:03:42,960 Like I know I want to do everything because before I remove I want to do I want to save all the data. 60 00:03:42,970 --> 00:03:48,720 Then it will be helpful to, you know, go to our exercise file and that is our general practice. 61 00:03:48,760 --> 00:03:50,660 I simply copy them here. 62 00:03:50,670 --> 00:03:52,050 I take one of the folder. 63 00:03:52,890 --> 00:04:02,970 So that is actually our my just name it as a backup backup file and into the backup file here I want 64 00:04:02,970 --> 00:04:05,490 to do and to define better. 65 00:04:05,490 --> 00:04:07,130 I just simply copy it fast. 66 00:04:07,650 --> 00:04:09,590 So that is our general practice here. 67 00:04:09,630 --> 00:04:12,840 I have created on the court application simply the backup. 68 00:04:12,840 --> 00:04:19,010 Finally, I just simply passed it and I just wanted to change that name and here and name it as a code. 69 00:04:21,420 --> 00:04:26,760 OK, that means there is a global application, so just name it as a code application. 70 00:04:27,360 --> 00:04:31,310 OK, so if you need this file then you can actually access it from here. 71 00:04:31,890 --> 00:04:32,330 Perfect. 72 00:04:32,610 --> 00:04:38,340 So now I wanted to change it like here right now I don't need any data, so I want to remove everything. 73 00:04:38,610 --> 00:04:40,740 I want to make things from fresh. 74 00:04:41,250 --> 00:04:42,540 Also, I don't need this. 75 00:04:42,540 --> 00:04:44,400 I want to do and remove it. 76 00:04:45,300 --> 00:04:47,700 So first of all, I want to compare both of these. 77 00:04:47,700 --> 00:04:50,940 That means I want to compare our with our function and the class. 78 00:04:50,940 --> 00:04:54,000 Then it'll be easy to understand you for doing this. 79 00:04:54,000 --> 00:05:01,740 First of all, here, I want to want to take our EDP response like there is a Django and into the Django 80 00:05:01,740 --> 00:05:04,280 that it is TDP that you already know about it. 81 00:05:04,650 --> 00:05:09,750 So here from here, I want to import as it is TDP response. 82 00:05:11,100 --> 00:05:11,460 Right. 83 00:05:11,460 --> 00:05:13,620 So I just simply added diversity principles. 84 00:05:13,920 --> 00:05:19,390 So before what exactly would be before we have created one of the function as an index function. 85 00:05:19,420 --> 00:05:21,480 So first of all, I want to work with this. 86 00:05:21,480 --> 00:05:23,880 Then I will make that thing with the class. 87 00:05:23,880 --> 00:05:29,680 Then it will be very much clear to you, like here I define as a request, right? 88 00:05:29,730 --> 00:05:34,320 So that is our request and the function of the we I just simply defined as the return. 89 00:05:34,950 --> 00:05:38,160 And then SCDP is TDP response. 90 00:05:38,160 --> 00:05:43,380 And here we pass some of the extreme data like the Hello the World. 91 00:05:44,490 --> 00:05:44,910 Right. 92 00:05:46,110 --> 00:05:49,020 And also for this, we have defined one of that. 93 00:05:49,110 --> 00:05:54,120 You want to like if you go here into this position, that means in our main you are Sadiya. 94 00:05:54,120 --> 00:05:57,420 We have already created one of the mapping into the application. 95 00:05:57,420 --> 00:05:59,040 I also created another dewatered. 96 00:05:59,320 --> 00:06:02,060 So, you know, many Warrell here are defined as a pathway. 97 00:06:02,100 --> 00:06:05,670 It will be as a home, then it will be redirected to our Fastweb. 98 00:06:05,670 --> 00:06:06,540 You are right. 99 00:06:06,810 --> 00:06:11,100 That means you will be elected to our this first application in the first application. 100 00:06:11,100 --> 00:06:11,770 That is all you are. 101 00:06:12,300 --> 00:06:13,860 So right now here, I don't need this. 102 00:06:13,860 --> 00:06:17,840 I just simply remove everything because I want to make the things from fresh. 103 00:06:18,180 --> 00:06:22,620 So here I have already added our input part and the final step. 104 00:06:22,620 --> 00:06:28,890 I have added the views and I have created one of the app as the app name, and I just defined that app 105 00:06:28,890 --> 00:06:30,150 name as a fast app. 106 00:06:30,150 --> 00:06:30,450 Right. 107 00:06:30,660 --> 00:06:32,850 And then that is our usual pattern. 108 00:06:33,270 --> 00:06:36,150 So now I want to do I want to actually load out these functions. 109 00:06:36,160 --> 00:06:39,990 So if you want to loaded this function, I think you already know about it. 110 00:06:39,990 --> 00:06:45,990 You have to define as a part and then view I we have defined as an index and I just name it as the index. 111 00:06:46,380 --> 00:06:49,110 So that is actually the way for our function view. 112 00:06:49,110 --> 00:06:50,640 So that is our function view. 113 00:06:50,640 --> 00:06:56,640 So if you want to visibly now, if you click to save all, I just click as to save all and now run our 114 00:06:56,640 --> 00:06:57,170 server. 115 00:06:57,810 --> 00:06:59,420 So Sara is now running. 116 00:06:59,430 --> 00:07:00,960 So now if you go to your home. 117 00:07:02,750 --> 00:07:05,510 Now you can is now returning as a hello world. 118 00:07:06,510 --> 00:07:10,940 So now, if you want to do the same things with the claspers view, how can do this work? 119 00:07:11,220 --> 00:07:16,770 So for doing this, we have to do we have to go through our view to the view so that in the view, that 120 00:07:16,770 --> 00:07:20,760 is actually our function of and I want to do an interview with the clouds, his view. 121 00:07:20,790 --> 00:07:26,130 So if you want to do that, well, first of all, here you have to do you have to add some of the class 122 00:07:26,580 --> 00:07:32,790 sizes and predefine of the farm and the Django sorry, into the jungle. 123 00:07:32,800 --> 00:07:41,370 They have also the views and the views that have all sort of the genetic, generic and the generic. 124 00:07:41,370 --> 00:07:42,590 Here we have to import. 125 00:07:42,840 --> 00:07:46,790 We have been put down one of the another class or the building class as a view. 126 00:07:47,130 --> 00:07:49,920 So I just simply added our this class as a view. 127 00:07:50,070 --> 00:07:53,870 And now I don't want to create another class, so I just name it as a class. 128 00:07:54,330 --> 00:07:59,610 And here I want to create the class name and I just name it as the index index view. 129 00:08:00,030 --> 00:08:02,090 This step of one of the class name I have defined. 130 00:08:02,100 --> 00:08:03,300 And now here we have to do. 131 00:08:03,300 --> 00:08:07,530 We have inherited our this class that we are building class. 132 00:08:07,530 --> 00:08:10,470 The views are just simply defend that view of a friend. 133 00:08:10,680 --> 00:08:15,420 And now into this class area we have to do we have to create one of the function so no one has to do 134 00:08:15,420 --> 00:08:19,920 and to create all the function as a dev and then the gate and here. 135 00:08:20,130 --> 00:08:24,930 And as I told you before, when you create any function into the class, then you have to define that 136 00:08:24,930 --> 00:08:26,010 things with the self. 137 00:08:26,010 --> 00:08:26,310 Right. 138 00:08:26,580 --> 00:08:30,330 So now I just simply defined as a self and then request. 139 00:08:31,230 --> 00:08:35,760 And then here I want to do and to pass on the return some of the text. 140 00:08:35,760 --> 00:08:40,200 So here I want to pass it with the study response and into the study response. 141 00:08:40,230 --> 00:08:44,460 Now I have to do and to show another message as a hello world. 142 00:08:45,930 --> 00:08:49,240 And that is and that is class based. 143 00:08:50,880 --> 00:08:52,590 OK, I understand that that is class. 144 00:08:52,590 --> 00:08:58,440 But so this testing, I want to pass it right now with our this class view so far, and I think you 145 00:08:58,440 --> 00:08:59,810 can well understand about it. 146 00:08:59,810 --> 00:09:05,490 So here I have the final of the class and I just named this class as an index view and the index view. 147 00:09:05,490 --> 00:09:08,150 I inherited our one of that building class. 148 00:09:08,150 --> 00:09:11,040 So we will be cast for our views and the generic. 149 00:09:11,280 --> 00:09:14,760 And from here I get our these building class as a view. 150 00:09:14,770 --> 00:09:16,410 So here I inherited it. 151 00:09:16,420 --> 00:09:22,020 OK, and after that, in this class area, I have to do I have to create one of the function and here 152 00:09:22,020 --> 00:09:25,290 I have to create the function as a gate and into this gate. 153 00:09:25,300 --> 00:09:30,180 As I told you, if you want to create any function into the class area, you have to pass one of the 154 00:09:30,180 --> 00:09:31,710 arguments to the self. 155 00:09:31,710 --> 00:09:32,100 Right. 156 00:09:32,310 --> 00:09:34,500 And then I just simply defined the request. 157 00:09:34,500 --> 00:09:36,270 And then I return our SCDP. 158 00:09:36,270 --> 00:09:37,790 One of the takes a hello world. 159 00:09:37,800 --> 00:09:38,970 That is the class based. 160 00:09:39,390 --> 00:09:41,670 So now we have to do we have to create one of that. 161 00:09:41,670 --> 00:09:42,870 You are for this one. 162 00:09:43,200 --> 00:09:48,500 But now if you want to create that, you are elenor our first application that you order and into the 163 00:09:48,510 --> 00:09:51,900 model area for the function we have defined as the views index. 164 00:09:51,900 --> 00:09:53,510 And I just name it as the index. 165 00:09:53,520 --> 00:09:53,790 Right. 166 00:09:53,820 --> 00:09:55,570 So before I have used that index. 167 00:09:55,570 --> 00:10:00,180 So now better I want to change it, then it shall be easy to understand you. 168 00:10:00,180 --> 00:10:01,440 I just name it as a test. 169 00:10:02,050 --> 00:10:07,140 OK, just name that function, name as a test to know what to do and to create another world for our 170 00:10:07,140 --> 00:10:07,940 claspers view. 171 00:10:07,950 --> 00:10:13,050 So if you want to display the class view you are old, then you have to do you have to define the views. 172 00:10:13,320 --> 00:10:16,500 And after this view we have to define your last name. 173 00:10:16,510 --> 00:10:20,970 So here I define the class name as index for you say just name it as the index view. 174 00:10:21,240 --> 00:10:27,310 And then after that, here you have to do you have to add your as under a score and that view. 175 00:10:27,870 --> 00:10:31,590 So here you have to add this as a as underscore view. 176 00:10:31,600 --> 00:10:34,890 OK, and then I just simply named this as an index. 177 00:10:34,890 --> 00:10:36,600 I just name it as the same name. 178 00:10:36,990 --> 00:10:38,180 So that is our part. 179 00:10:38,190 --> 00:10:40,040 So here I have defined that entity. 180 00:10:40,050 --> 00:10:43,350 That means there shall be our home popped right into the home. 181 00:10:43,350 --> 00:10:45,980 But I have defined that views in our index. 182 00:10:45,990 --> 00:10:48,240 That is the index view that is actually our class name. 183 00:10:48,240 --> 00:10:53,880 And here I define as as few as, which means it will be called our this class. 184 00:10:53,880 --> 00:10:55,620 That means this class as a view. 185 00:10:55,890 --> 00:10:58,770 So for the reasons here, you have to add that as a view. 186 00:10:58,770 --> 00:11:00,720 And then there is our name of the index. 187 00:11:00,900 --> 00:11:05,100 So that is the main basic difference between function and the class. 188 00:11:05,130 --> 00:11:12,210 So now if you run it like I just click and save all, so our server is now running and now if you refresh 189 00:11:12,210 --> 00:11:12,510 it. 190 00:11:13,260 --> 00:11:14,060 Yes. 191 00:11:14,070 --> 00:11:19,590 Now, considering now that is a lower class vis view and is now showing all this same data as a hello 192 00:11:19,590 --> 00:11:24,630 world, and that is that class space, I hope you get the little bit idea. 193 00:11:24,670 --> 00:11:28,430 What is the difference between our function based view and the clouds? 194 00:11:28,510 --> 00:11:28,950 His view. 195 00:11:28,950 --> 00:11:29,260 Right. 196 00:11:29,580 --> 00:11:35,040 So now if you want to add some of the templates before we have already defined s the template for our 197 00:11:35,040 --> 00:11:40,560 functions, if you want to add some of the template view into the clouds visible area, how can do that 198 00:11:40,560 --> 00:11:40,820 work? 199 00:11:40,830 --> 00:11:42,930 But I don't want to continue this process. 200 00:11:42,930 --> 00:11:45,920 In our next video, I will show that things with the live example. 201 00:11:46,500 --> 00:11:48,090 So thanks for watching. 202 00:11:48,090 --> 00:11:49,830 I will see you in the next video.
