WEBVTT 00:06.260 --> 00:07.620 Everyone wrote them back. 00:07.860 --> 00:14.940 So in the previous video we saw that we finished the classification and the registration of the API. 00:15.030 --> 00:20.430 So the final thing that we need to do is to do the refill of the API. 00:20.430 --> 00:21.080 OK. 00:21.210 --> 00:23.360 So we're going to go go back here. 00:23.370 --> 00:29.190 So we're going to come back here and then we're going to finally write the Rayfield class which we did 00:29.190 --> 00:32.770 it in a similar video before so it shouldn't be something new. 00:32.770 --> 00:33.040 Right. 00:33.040 --> 00:35.860 So we're going to go through it fairly quickly OK. 00:36.060 --> 00:37.550 So that's a good start. 00:37.680 --> 00:40.970 So the first thing is we need to write a class which is called refill. 00:40.980 --> 00:41.820 Right. 00:41.940 --> 00:49.890 As the resource and we inherit from the resource class and then we said we discussed that it's going 00:49.890 --> 00:51.350 to be a post right. 00:51.390 --> 00:54.460 So we're going to see a post of self. 00:55.260 --> 00:59.750 And then first of all the first step in post is usually to get the post to do us or we're going to say 00:59.750 --> 01:05.030 a posted up equal to a request not get Jaisalmer. 01:06.390 --> 01:13.080 Once we have the posted data then we need to get the username password and the amount that is to be 01:13.080 --> 01:21.660 added right and be careful that the password here is not the user's password but rather the administrators 01:21.690 --> 01:22.700 password right. 01:22.800 --> 01:33.150 So we're going to say a user name username is equal to the posted data and then username password is 01:33.150 --> 01:35.540 equal to posted data. 01:35.820 --> 01:40.860 And then inside of it we're going to call it admin underscore P.W. and password. 01:41.160 --> 01:45.790 And then finally the amount is equal to the posted data. 01:46.560 --> 01:49.190 At the same amount. 01:49.260 --> 01:52.150 OK so it's going to send it in the field amount. 01:52.590 --> 01:57.240 OK so we have the username password and amount so the first thing is we need to check that this user 01:57.240 --> 01:58.030 exists. 01:58.200 --> 02:01.690 So I'm going to say if not user exists. 02:01.890 --> 02:06.640 Ok so if this username doesn't exist then what do I do. 02:06.960 --> 02:11.090 Well I return an error as I say return. 02:11.160 --> 02:16.500 Jason if I and then we're going to use the function that we wrote generate return dictionaries and when 02:16.490 --> 02:18.260 I say return. 02:18.720 --> 02:25.050 So here generate return Dictionnaire gate and then the error code is going to be 301 because there is 02:25.050 --> 02:29.000 an invalid username and for the message it might tell the user. 02:29.010 --> 02:34.070 Well you know what invalid you don't want to see invalid username username. 02:34.170 --> 02:35.050 OK. 02:35.400 --> 02:36.110 And that's it. 02:36.120 --> 02:38.970 So that's for the existence of the user. 02:38.970 --> 02:42.510 We also said that the administrator password might be incorrect. 02:42.580 --> 02:48.470 I'm going to say the correct administrative password should be no ABC 1 2 3. 02:48.480 --> 02:52.560 Ok so maybe that's the administrative password that we choose. 02:52.560 --> 03:01.200 So I'm going to say if not password is equal to correct password then in that case I'm going to return 03:02.610 --> 03:04.770 3 0 2 which is an incorrect password. 03:04.770 --> 03:11.740 So I'm going to say return Jason if I generate or actually it should be I think three or four. 03:11.940 --> 03:12.230 Right. 03:12.240 --> 03:20.420 Because it's it's the invalid administrator password so it's invalid. 03:20.670 --> 03:26.200 Adman's traitor password might have misspelled it it's fine. 03:26.710 --> 03:27.360 OK. 03:27.480 --> 03:37.170 So once we have that then the next step is to update our users or our users database so that he has 03:37.170 --> 03:38.360 the new amount right. 03:38.400 --> 03:39.800 So how am I going to do that. 03:39.930 --> 03:43.330 Well I'm going to do users that update. 03:43.560 --> 03:44.330 OK. 03:44.700 --> 03:49.570 And then in here choose the user which has the corresponding user name. 03:50.340 --> 03:56.280 And what I'm going to update them is I'm going to set his number off tokens so I'm going to do a dollar 03:56.280 --> 04:02.710 set and then I'm going to have changed the number of tokens he has to the amount. 04:02.730 --> 04:03.310 OK. 04:03.360 --> 04:06.350 So the amount here is whatever I sent. 04:07.350 --> 04:08.400 And that's should be. 04:08.410 --> 04:11.550 So the final thing is to return a success to the user. 04:11.570 --> 04:18.690 So I don't say congratulations you have your AP You know you've added refilled the correct amount of 04:19.500 --> 04:19.940 stuff. 04:19.950 --> 04:27.680 So I'm going to see a return on I and then generate return dictionary inside of it. 04:27.690 --> 04:28.830 I'm gonna give 200. 04:28.830 --> 04:31.620 So it's a success and I'm going to give them a message. 04:31.630 --> 04:33.460 I want to refill. 04:33.660 --> 04:36.620 So refill maybe successfully. 04:37.100 --> 04:38.280 OK. 04:38.460 --> 04:39.440 All right. 04:39.480 --> 04:40.770 So now that should be it. 04:40.770 --> 04:43.280 So we're done with the refill. 04:43.290 --> 04:49.020 We're done with the classify glass and we're done with the registration. 04:49.100 --> 04:49.560 OK. 04:49.620 --> 04:51.800 So we're done with all of the resources. 04:51.810 --> 04:53.940 Now we need to add them to the API. 04:54.090 --> 04:54.510 So I do. 04:54.540 --> 04:59.080 AP I got to add resource and resource. 04:59.250 --> 05:00.250 And then I'm going to add. 05:00.270 --> 05:01.880 First of all register. 05:02.620 --> 05:09.180 And if you remember from the image we said or from the chart we said we're going to do it at slash register. 05:09.240 --> 05:10.140 Okay. 05:10.560 --> 05:20.020 And then we're going to do API to add resource Rumana at the classify glass and we're going to put it 05:20.050 --> 05:31.500 at slash classified slash classify finally resigned you add the last resource which is the real. 05:32.130 --> 05:34.070 And we're going to add it as Slash free. 05:34.110 --> 05:36.570 Great. 05:37.330 --> 05:44.390 Finally the last step is as usual if name is equal to main. 05:44.450 --> 05:52.040 So if it's main then we do at Dharan and then host is equal to and this is the most important piece 05:52.040 --> 05:52.970 of the code. 05:53.030 --> 05:55.290 Zero point zero point zero point zero. 05:55.320 --> 05:55.920 OK. 05:56.030 --> 05:59.770 So this is the host and readouts are done with the API. 05:59.780 --> 06:02.820 Just almost 150 lines of code. 06:03.010 --> 06:03.770 Not too big. 06:03.800 --> 06:04.370 OK. 06:05.860 --> 06:07.260 That can make it smaller. 06:07.260 --> 06:13.390 Probably you know for example these things like updates we can write a function that up these things 06:13.420 --> 06:17.340 automatically so it can take this just in one line of code. 06:17.650 --> 06:23.720 For example this update to you can change it in one line of code so you can do a lot of stuff here. 06:23.780 --> 06:29.190 Let's let us remove these two Tutu's because we're done with them to do it right. 06:29.230 --> 06:31.860 So yeah hopefully this wasn't too hard. 06:32.320 --> 06:40.390 It's just the main idea here is the classifying class and actually everything beyond this area here 06:40.510 --> 06:42.250 is actually pretty old. 06:42.280 --> 06:43.920 So we've discussed it before. 06:43.960 --> 06:49.870 So the only new area here I would say is the request get your elso we got that you are well from the 06:49.940 --> 06:55.170 requests we generated the result Jason or dictionary. 06:55.240 --> 07:02.710 And then we opened the image store that so we store the the image from their request that we got from 07:02.710 --> 07:07.590 their request and then we opened a new process and we ran in it. 07:07.600 --> 07:12.480 Lifeson classified image model directory in my file. 07:12.490 --> 07:17.910 Then I communicated with the process and I waited until the process subprocesses done. 07:18.010 --> 07:27.290 And finally this process year we changed it so that it writes text that DST file and that and it stores 07:27.310 --> 07:28.430 and dumps in it. 07:28.740 --> 07:30.890 The risk very turned up. 07:31.120 --> 07:38.930 So what I do here is to open it and retrieve the dictionary once I have that then I'm willing to return. 07:39.140 --> 07:41.360 Richard Jewson and that's about it. 07:41.360 --> 07:46.840 So we're going to stop here and the next video we're going to be testing the API just see how it works 07:47.110 --> 07:49.020 how we can interact with it. 07:49.150 --> 07:54.610 And you know see if it can work correctly classify a couple of images so let's give it a image of a 07:54.610 --> 07:58.520 zebra or a panda and see if it works or not. 07:58.570 --> 08:02.670 They're just up here and will pick up in the next minute or so until the next minute. 08:02.740 --> 08:03.490 Happy Cody.
