WEBVTT 00:05.280 --> 00:08.860 I everyone welcome back because let me clear this first before we start. 00:09.080 --> 00:14.960 So in this video we're going to be finally showing the Abiah either worried that we just built a new 00:14.960 --> 00:21.260 world to see how different you know how we can use all its different features to do different things 00:21.260 --> 00:25.350 like We can simulate if we have a two bank accounts and so on. 00:25.400 --> 00:26.070 OK. 00:26.300 --> 00:28.010 So yeah let's get started. 00:28.010 --> 00:30.070 So first of all we want to build the project. 00:30.200 --> 00:35.990 Now I removed all the files from this bank API into the tutorial as I always do but this you should 00:35.990 --> 00:37.850 be fine if you're in A.P.. 00:37.910 --> 00:40.220 I'm going to go back loops. 00:40.290 --> 00:44.350 So I want to go back and I'm going to go into tutorial one gig. 00:44.530 --> 00:50.240 I'm going to do Sudhakar compose build lot to build this product. 00:51.050 --> 00:52.000 OK. 00:53.830 --> 01:02.260 And once it finishes downloading all of the stuff that is related to Python and flask and all the libraries 01:02.260 --> 01:10.600 that we need and we do then we once we have that then we're going to be able to implement or to test 01:10.600 --> 01:11.310 the API. 01:11.320 --> 01:16.680 Once we do Divakar compose up so it should be done now. 01:16.750 --> 01:25.120 And now we do so do Darger compose out and now it's running so you can see that it's running now localhost. 01:25.140 --> 01:30.620 So let's open up the postman's let's get rid of this year and this year. 01:30.800 --> 01:31.500 OK. 01:31.680 --> 01:34.760 So we got Does that localhost five townland. 01:34.890 --> 01:39.920 First of all let's register again to register and then I'm going to register. 01:39.960 --> 01:46.310 So I want to send the Gs on the first account that I want to register is actually the bank account right. 01:46.330 --> 01:51.900 This is the first account that is always made to the bank and is going to have a password Daas Let's 01:51.900 --> 01:54.250 see secure game. 01:54.780 --> 01:58.180 So as we usually choose a very very secure password. 01:58.610 --> 01:59.160 OK. 01:59.340 --> 02:06.790 So now if I try and I send it to the bank tell me you've successfully signed up for the API status is 02:06.790 --> 02:07.540 too hungry. 02:07.560 --> 02:11.520 OK great so now we have a status code. 02:11.560 --> 02:13.670 And we signed the bank. 02:13.720 --> 02:20.260 So if you want to check the balance of the bank so we can go back slash balance and then you can see 02:20.260 --> 02:27.360 that the bank doesn't own anything and doesn't have a debt against 0 0 caseless joint and maybe zoomin 02:27.370 --> 02:28.210 a bit. 02:28.530 --> 02:30.370 OK so now I'm going to do. 02:30.520 --> 02:32.160 I'm going to register another person. 02:32.190 --> 02:39.250 So when I register to persons I actually test one and test two and they're both going to have the same 02:39.280 --> 02:40.210 battery. 02:40.480 --> 02:46.800 So when I signed up test one I also got us test two. 02:46.970 --> 02:52.920 Now if I try to sign up to twice then I should get an ear that says Invalid use your name Suria Why. 02:52.980 --> 02:56.820 Because this user name is used already exists. 02:56.840 --> 03:00.030 Ok so now I have two people now let's say Bruce. 03:00.050 --> 03:00.800 Just one. 03:00.800 --> 03:06.900 So Burreson just one adds some money so I'm going to change that to add and he adds some amount less 03:06.920 --> 03:09.570 the amount is hundred bucks. 03:09.590 --> 03:10.120 OK. 03:10.190 --> 03:19.330 So he adds $100 and I click send so that tells me amount and successfully talk to a guy. 03:19.340 --> 03:25.650 So the user ended up going to the bank he paid $100 in cash and the bank added it to his account. 03:25.820 --> 03:32.460 So now if I check the balance of the test one then I'm going to see that he has. 03:32.510 --> 03:33.850 He owns ninety nine. 03:33.890 --> 03:37.170 Well why is it 9 9 because the banks don't remember. 03:37.170 --> 03:40.340 Don't forget the bank got one dollar right. 03:40.340 --> 03:41.920 The transaction fee. 03:41.990 --> 03:44.330 So the user only has $99. 03:44.350 --> 03:47.900 Right because for each transaction the bank takes $1. 03:47.900 --> 03:54.250 Now if I check the bank the balance of the bank it should be one right so he should own one. 03:54.290 --> 03:56.350 As you can see your own is one. 03:56.660 --> 03:57.510 OK. 03:57.860 --> 04:00.720 Now let's say So let's go. 04:00.740 --> 04:09.380 So let's say that just one example wants to transfer some money to just to get someone to add an extra 04:09.380 --> 04:14.030 field to and then I'm going to say this field is for example desk too. 04:14.390 --> 04:15.220 OK. 04:15.410 --> 04:17.160 So I want to send some. 04:17.180 --> 04:28.000 So money's let's say $20 from tests wanted us to someone to do slash transferred and then send it and 04:28.010 --> 04:31.100 then it will tell the amount as successfully to account. 04:31.100 --> 04:38.240 So if I check the balance of desk to select needs change this huge to test do I check the balance. 04:38.690 --> 04:47.050 Well that balance should be 19 because the bank took one dollar as a transaction fee. 04:47.160 --> 04:49.480 So it ends up being only 19. 04:49.650 --> 04:53.630 But if I check the bank balance off just one. 04:53.820 --> 04:54.640 OK. 04:54.930 --> 05:01.000 Then he should have 90 99 minus 20 which is 79 right as it's shown here. 05:01.320 --> 05:04.250 So yeah this is basically the guy you can also take a loan. 05:04.260 --> 05:06.660 Let's try and take a loss and take a loan. 05:07.010 --> 05:16.080 So let's say test tube wants to take a loan a $5 a game does not take a loan and he's added. 05:16.140 --> 05:17.160 So he's taken a loan. 05:17.160 --> 05:25.210 So let's check his bank balance now or her balance on you know either male or female. 05:25.350 --> 05:30.090 So he now he owns $24 and he has a debt of five. 05:30.210 --> 05:36.930 So now I'm going to take away from his money and pay for the debt so I'm going to do change to pay loan. 05:37.170 --> 05:37.950 OK. 05:38.160 --> 05:43.180 And then I want to see just do not pay five dollars to the loan. 05:43.260 --> 05:44.180 OK. 05:44.670 --> 05:46.240 And then says loan paid. 05:46.290 --> 05:52.790 So if I now check the balance of debt to then you can see that he has lower money. 05:53.200 --> 05:56.450 So this is basically the API and that were developed. 05:56.440 --> 06:02.130 So you feel free to play around with that if you find any problems in it or mistakes just let you know 06:02.120 --> 06:08.830 in the Q and A section and I'll let everyone else know that there was a problem and shouldn't be too 06:09.000 --> 06:10.740 you know too huge of a problem. 06:10.750 --> 06:14.700 Hopefully so yet we're going to stop here and we're not pick up in the next. 06:14.730 --> 06:16.810 And so until the next video become the.
