WEBVTT 00:05.200 --> 00:07.010 Hi everyone welcome back. 00:07.010 --> 00:11.380 So in this video we're going to do the final class which is to refill class. 00:11.390 --> 00:12.650 So let's get started. 00:12.890 --> 00:19.570 So the last feature we have here is a refill which basically allows the admin to refill for any user 00:19.790 --> 00:23.730 whatever amount of refills that he would like it. 00:23.780 --> 00:26.760 So we're going to write the class glass refill. 00:26.940 --> 00:27.330 OK. 00:27.330 --> 00:29.810 And then we're going to inherit from resource. 00:30.650 --> 00:35.450 And as we discuss it's also a post so as you can see here it's a post. 00:35.840 --> 00:40.690 So we to post and then self. 00:40.880 --> 00:45.120 OK so the first thing is as usual we want to get the posted data. 00:45.270 --> 00:52.670 We do posted data is equal to and then we want to get the user name and the password. 00:52.710 --> 00:53.200 OK. 00:53.310 --> 00:56.900 So we want to get a couple of things actually we want to get the user name. 00:57.020 --> 01:01.110 You want to get the admin password and we want to get the full amount. 01:01.440 --> 01:05.360 So when I get posted so that's OK. 01:05.400 --> 01:10.340 So the Post day that is the request that we get Jason. 01:10.590 --> 01:11.600 OK. 01:12.230 --> 01:26.240 So this should be done to get Gs on and then username is equal to posted data and then username and 01:26.310 --> 01:31.390 then we have the admin password so password is equal to posting data. 01:32.010 --> 01:35.650 And then we're going to access it at admen underscore piñon. 01:35.710 --> 01:36.320 Great. 01:36.570 --> 01:40.770 So it's a hidden field with not just password. 01:41.120 --> 01:41.890 OK. 01:42.090 --> 01:49.190 Then the last thing is refill amounts a refill is equal to the posted data. 01:49.560 --> 01:51.380 Or let's say a refill amount. 01:52.540 --> 01:56.860 Is equal to posted data and then refill. 01:56.930 --> 01:57.730 OK. 01:58.180 --> 02:03.730 So hopefully this meets us so we we are basically getting the user and the admin and refill amount from 02:03.730 --> 02:09.410 the posted to you that we've got at this you are out now. 02:09.520 --> 02:13.400 The next thing we want to do is we want to check for a three or one and 3 or. 02:13.440 --> 02:19.330 If you see here we have three old ones and three or four three and one is invalid use your name and 02:19.330 --> 02:21.930 three or four is invalid admin password. 02:21.970 --> 02:23.000 OK. 02:23.290 --> 02:24.570 So let's go back. 02:24.850 --> 02:29.390 So the first thing is how do we check for three or one and we've already done it before. 02:29.390 --> 02:29.870 So you're right. 02:29.890 --> 02:37.840 If not use or exist if this user doesn't exist with this username then we're going to return return 02:37.840 --> 02:42.850 Jason is equal to status 2 0 1 3 0 1. 02:43.060 --> 02:50.120 And the message I want to tell him something for example invalid Youzhny so sorry invalid. 02:50.860 --> 02:59.250 And then I'm just going to return on if I have returned Jason or the return map. 02:59.470 --> 03:02.530 OK so that's for the three to one year. 03:02.680 --> 03:06.350 Now what about the checking for the password right. 03:06.370 --> 03:11.750 So you want to make sure that the correct admin password is is the same. 03:11.800 --> 03:17.800 Now there are many ways you can do this we can also use hashing just like we use for the regular or 03:17.800 --> 03:22.470 the regular username password but for the sake we're just going a hard chordates are we going to see 03:22.470 --> 03:25.510 the correct password is equal to. 03:25.680 --> 03:26.180 I don't know. 03:26.230 --> 03:29.540 ABC 1 2 3 this is not the best practice. 03:29.550 --> 03:36.280 It's always better not to store any passwords in this app you file but instead store it in the database 03:36.280 --> 03:37.280 securely. 03:37.510 --> 03:42.790 But for now we can just hardcoded because we already know how to hash the function so there's no point 03:42.790 --> 03:44.530 in just making this longer. 03:44.530 --> 03:49.600 So for now we're just going to go with it but you should know that you should nost or any passwords 03:50.200 --> 03:57.160 inside this app QIC you should actually just store it in the database and always access the hashed version 03:57.160 --> 03:57.960 off it. 03:58.000 --> 04:03.850 So you should store the hash version of your correct password in the administrator for example and you 04:03.850 --> 04:09.490 make a new collection called Administration admin and then you would store the user name and the correct 04:09.520 --> 04:10.350 passwords here. 04:10.390 --> 04:11.030 OK. 04:11.170 --> 04:18.340 But for now we're just going to store the correct answer and then we're going to say if not password. 04:18.370 --> 04:25.420 So if the password that that it was signed that was sent is not equal to the correct password that in 04:25.420 --> 04:34.210 that case we want to tell the the the sender three or four sorry you sent an invalid admin password. 04:34.220 --> 04:34.840 OK. 04:35.060 --> 04:41.510 So I'm going to say return Jaisalmer is equal to status is three or four. 04:41.680 --> 04:49.690 And the message is let's say Invalid admin passwords so invalid admin password. 04:49.740 --> 04:57.390 Great and just return Jaison if I attorneys get. 04:57.740 --> 05:05.610 So really this wasn't too hard now once we have we have this sorry excuse me. 05:05.800 --> 05:12.100 So once we have this then we need to update the user to give him the new refill amounts. 05:12.100 --> 05:12.700 OK. 05:12.880 --> 05:17.200 So first thing we're going to do is we're going to see tokens. 05:17.390 --> 05:18.090 Right. 05:18.520 --> 05:23.190 Our current tokens is equal to you. 05:23.500 --> 05:30.730 And then we're going to say count tokens use the function that we wrote and then for this username and 05:30.730 --> 05:34.280 then we're going to say users update. 05:34.430 --> 05:38.660 So I'm going to update is this user OK. 05:39.540 --> 05:40.910 Yes. 05:41.210 --> 05:41.810 OK. 05:41.960 --> 05:49.630 So first of all I want to search for the user name as the one I have and for what I'm going to update 05:49.630 --> 05:51.730 hems and when I set. 05:51.760 --> 05:59.580 Right so I'm going to do another Giese in here for what I want to set of dollars. 06:00.210 --> 06:04.070 Then inside here I'm going to write tokens. 06:04.220 --> 06:11.870 I want to update his organs so that they are refill amount plus current tokens right. 06:11.900 --> 06:14.220 So I want to refill them for example hundred. 06:14.270 --> 06:17.930 And if he already has like five then I want him to have 105. 06:17.960 --> 06:18.660 OK. 06:20.620 --> 06:22.700 So that should be it to do it. 06:22.710 --> 06:23.990 The number of tokens. 06:24.100 --> 06:30.160 And then finally I want to prepare the theater and Jason to Dohme success or return James on to his 06:30.820 --> 06:37.630 status is 200 hundred and for the message is going to be. 06:37.630 --> 06:42.120 For example Rayfield successfully. 06:42.540 --> 06:45.040 So Greifeld this successfully. 06:45.260 --> 06:48.300 And then just returned G-ds on return. 06:48.310 --> 06:50.400 Jason ephi eternity's 06:53.660 --> 06:59.290 Imp's So we have now finished writing all of these 07:02.800 --> 07:09.480 functions and classes just a couple of things so for now I'm just going to remove this current tokens 07:09.480 --> 07:11.560 are not going to add screen tokens. 07:11.740 --> 07:15.910 So I'm going to make it overload the number of tokens that I have. 07:15.910 --> 07:20.770 So for example if the user has five and he refills them he loses these five. 07:20.770 --> 07:22.100 You only guess the new one. 07:22.150 --> 07:23.290 OK. 07:23.620 --> 07:27.720 You can you can leave it if you want but I just prefer you to leave it that way. 07:27.760 --> 07:28.580 OK. 07:29.050 --> 07:34.930 Now a couple of things that we have to do is to add a couple of things so AP to add resource we need 07:34.930 --> 07:42.940 to add all the resources that we wrote so add resource and then we want to add the register class at 07:43.870 --> 07:45.070 slash register. 07:45.070 --> 07:51.650 If you remember we have here the chart slash register slash the text slash ratio. 07:51.760 --> 07:52.330 OK. 07:52.660 --> 07:55.480 So we're going to add the register to slash register. 07:55.690 --> 08:04.670 We're going to add the resource on detect to slash detect. 08:05.470 --> 08:17.640 And I'm going to add the resource ratio OK to slash refill. 08:18.250 --> 08:27.710 Ok now I'm going to run the applications I want to see if name is equal to main. 08:28.110 --> 08:34.770 Right as we always do then the run host is equal to. 08:34.770 --> 08:37.070 Don't forget this one is very important. 08:37.090 --> 08:39.360 Zero point zero zero point zero OK. 08:39.600 --> 08:47.210 So this is the house where we're going to run everything on and that should be it for the API in general 08:47.210 --> 08:54.560 so we've written an API which measures the similarity of two codes using hundred seventy five lines 08:54.560 --> 08:58.260 of code with lots of empty lines in the middle. 08:58.490 --> 09:05.110 But we can actually make this you know a lot you know very very small. 09:05.210 --> 09:11.080 And the reason is that if you notice you're We always have this returned Jason equal to we generate 09:11.090 --> 09:16.880 this return to the center of that range and then just 25 it will actually we can call this as a function 09:16.880 --> 09:17.350 right. 09:17.510 --> 09:22.750 So we can actually make this as a function and then we just pass it the status quo. 09:22.820 --> 09:25.990 And the message and then it generates all of this. 09:26.090 --> 09:29.430 But for now we're just going to leave it in the most intuitive way. 09:29.470 --> 09:32.370 It doesn't have to be you know production line ready. 09:32.390 --> 09:37.220 Definitely not production line ready but at least for now we know that it works. 09:37.460 --> 09:43.100 And in the next video we're going to see how we can test it and just take it on a run try the registration 09:43.100 --> 09:46.380 detection refill see if there's any problems. 09:46.380 --> 09:50.970 And so we're going to stop here and I'm going to see you in the next video. 09:50.980 --> 09:53.000 So until a nice video happy Cody.
