WEBVTT 00:01.920 --> 00:02.450 Okay. 00:02.460 --> 00:06.080 We have our own method here rate movie. 00:06.090 --> 00:09.360 So let's work a little bit more on this method now. 00:09.360 --> 00:17.040 So what we first need to do is we need to get some data for that rating. 00:17.040 --> 00:22.080 So we need to check if something has been passed in the request. 00:22.080 --> 00:26.460 So let's say if we we required a stars, for example. 00:26.460 --> 00:29.010 So if stars. 00:31.300 --> 00:37.480 In request data, then we can do this. 00:39.990 --> 00:44.520 And so we can output that only when we start in request data. 00:44.520 --> 00:50.250 And then else I can do, for example. 00:51.770 --> 00:53.030 Something like this. 00:53.030 --> 00:54.860 So I will have message. 00:56.870 --> 01:10.940 You need to provide stars like that and then status will be Http and then we can use something like 01:10.940 --> 01:12.830 a bad request here. 01:13.820 --> 01:17.420 So what I'm doing now, I will make more space here. 01:18.500 --> 01:24.770 So what I'm doing now is I'm checking if you have stars in the request data and I will show you what 01:24.770 --> 01:26.330 does it exactly mean. 01:26.330 --> 01:32.450 And then if you don't have it, then we'll put you need to provide stars with a bad request. 01:32.450 --> 01:34.070 If you have it, then it will be. 01:34.070 --> 01:34.640 It's working. 01:34.640 --> 01:35.990 So let's test it now. 01:36.350 --> 01:37.820 I will run it again. 01:39.740 --> 01:45.350 And come back to our postman and let's try to do the same method as we've done before. 01:45.830 --> 01:51.860 And you can see here message you need to provide stars and why we are seeing this. 01:52.490 --> 02:05.910 We set here if stars in request data request data is that body that we will send along with our request. 02:05.930 --> 02:10.260 So basically we need to provide stars like that. 02:10.280 --> 02:20.630 So at this point we don't validate this stars anyhow, so we can do whatever here. 02:22.850 --> 02:23.360 Whatever. 02:25.610 --> 02:28.970 Whatever here. 02:28.970 --> 02:34.290 And if I will now send it, you can see the message is working. 02:34.310 --> 02:40.340 The reason we see this message is because we passed the stars to our. 02:40.730 --> 02:43.370 So it's a part of the request data. 02:43.370 --> 02:50.200 So stars now are in the request data so we can output this. 02:50.210 --> 02:58.100 So basically you can see that how we can construct the logic inside our functions so we can decide what 02:58.100 --> 03:04.400 needs to be in the request data and then prohibit user to do something if it's not there. 03:04.400 --> 03:13.310 And also we can have another checks and logic so we can decide if the start is integer, if it's actually 03:13.670 --> 03:16.400 in between 1 and 5 and so on and so on. 03:16.400 --> 03:19.910 So everything can be validated here. 03:19.910 --> 03:25.470 We can do a lot of things with the data, but I will also show you another thing. 03:25.470 --> 03:31.980 So we will have our logic here, but I will try to print something, whatever we will try to use. 03:31.980 --> 03:38.310 You can see here, when we run the server, everything, what we ask the server, it's printed here, 03:38.310 --> 03:43.020 but we can send our own information to that console, to that terminal. 03:43.020 --> 03:44.700 So let's do it now. 03:44.700 --> 03:48.540 So I will do print and let's try to print that. 03:50.800 --> 03:51.550 Here. 03:51.850 --> 03:57.700 If I will print it now, I will go back to the postman and send it once again. 03:58.180 --> 03:59.530 You can see it's working. 03:59.530 --> 04:00.580 Nothing has been changed. 04:00.580 --> 04:01.590 It's 200. 04:01.600 --> 04:05.980 But if I come back here, you can see here that's printed one. 04:05.980 --> 04:09.940 It's the ID that has been passed with this method. 04:09.940 --> 04:14.890 So if I will come back here and remove it from there like that. 04:16.450 --> 04:18.400 It's not working. 04:18.400 --> 04:26.170 So that means this rate movie is, as I said before, it's only working for that specific movie. 04:26.170 --> 04:27.520 So it will be movie one. 04:27.520 --> 04:32.650 That's movie one, and then we will have an access to our pcq-pcc. 04:32.680 --> 04:33.640 It's a primary key. 04:33.850 --> 04:36.460 So basically that's our ID of the movie. 04:36.460 --> 04:41.560 So what we can do is we can select that movie from our database. 04:41.560 --> 04:45.460 So we said movie and then we can do movie. 04:47.650 --> 04:48.520 Objects. 04:51.840 --> 04:54.300 And then we can use get. 04:55.200 --> 05:05.520 So we will try to get the movie based on the PK so we know what is the primary key from that request 05:05.520 --> 05:08.850 because it's part of the URL, and then we select the movie. 05:08.850 --> 05:13.530 So what we have here is we'll have an access to that specific movie. 05:13.530 --> 05:15.750 So let's try to print something. 05:15.750 --> 05:21.180 Now I will print movie title that's just a static text. 05:21.180 --> 05:26.370 And here as a second argument, I will pass movie and then title like that. 05:26.370 --> 05:30.060 So we are selecting our movie from the database. 05:30.060 --> 05:37.560 Movie objects get based on the primary key, which is ID from the URL and then we will print the movie 05:37.590 --> 05:38.310 title. 05:39.210 --> 05:41.310 So let's come back here. 05:41.310 --> 05:42.420 That's been refreshed. 05:43.930 --> 05:46.360 Postman and I will send it again. 05:46.690 --> 05:47.440 This is. 05:47.440 --> 05:48.310 It's working. 05:48.310 --> 05:50.200 So we need to go here. 05:50.200 --> 05:53.230 And you can see here movie title Titanic. 05:53.380 --> 05:55.390 So this is printed. 05:55.660 --> 06:01.360 This is printed here because I have movie title and then movie title here, which is the ID. 06:02.400 --> 06:03.180 One. 06:03.180 --> 06:11.040 So if I will come back here and if I will change this to two to our second movie and send it again. 06:12.440 --> 06:13.280 In our. 06:14.810 --> 06:17.780 Control half movie title Avatar. 06:17.870 --> 06:26.030 So you can see how we can actually select something from our database and how we can manage this. 06:26.030 --> 06:34.010 So we have access to our stars now so we know what is the stars and how the stars will be passed. 06:34.010 --> 06:39.140 With the request data, we will check that first and otherwise you need to provide a stars. 06:39.140 --> 06:40.460 That's what we output. 06:40.700 --> 06:46.610 Next thing we check, what is the movie actual that we target? 06:46.610 --> 06:49.520 So we we have access to this movie. 06:49.550 --> 06:51.200 What else we can do? 06:51.230 --> 07:00.290 We need to also get the user data and I will show you how we can actually access the user data from 07:00.290 --> 07:05.240 the request in the next movie and we will finish that function.
