1 00:00:06,390 --> 00:00:07,530 Welcome back. 2 00:00:07,560 --> 00:00:12,680 In this video, let's see how we can update record Inside Mongoose. 3 00:00:12,690 --> 00:00:20,190 So let's go to the documentation and let's find the method called find by ID and update. 4 00:00:20,550 --> 00:00:27,210 You can see we have one method call find by one and update. 5 00:00:27,330 --> 00:00:37,320 So for this one we can use to find any document with any field, it can be named Title H or ID and we 6 00:00:37,320 --> 00:00:43,740 have one called find by ID and update is also work in the same way. 7 00:00:44,040 --> 00:00:50,580 So let's work with the find one and update and see how it's going to work. 8 00:00:50,580 --> 00:00:57,210 So let's click on find one and update or we can set it here as find one and update. 9 00:00:57,210 --> 00:00:58,710 So here we go. 10 00:00:59,010 --> 00:01:03,870 And it will see that for this one it is in couple of arguments. 11 00:01:04,410 --> 00:01:07,170 The first one going to be the query we want to find. 12 00:01:07,170 --> 00:01:12,270 It can be a title, it can be ID and then the doc and the additional option. 13 00:01:12,280 --> 00:01:13,020 I'll start. 14 00:01:13,020 --> 00:01:17,910 So let's see how we are going to implement it inside that. 15 00:01:18,150 --> 00:01:21,210 So it provides additional option as new. 16 00:01:21,210 --> 00:01:29,610 It simply means that we want to see the updated data on the fly as soon as is being saved without refreshing. 17 00:01:29,760 --> 00:01:36,810 So this option is really crucial or important and we see that default false and we change in version 18 00:01:36,810 --> 00:01:37,560 point oh. 19 00:01:37,800 --> 00:01:44,430 So I think with the new version, there is no need to provide the new because it should be updated and 20 00:01:44,430 --> 00:01:47,280 we are using version 6.5.3. 21 00:01:47,280 --> 00:01:50,850 So I think there's no need to provide a new argument. 22 00:01:50,850 --> 00:01:52,830 So let's see how you're going to achieve that. 23 00:01:53,040 --> 00:02:03,420 So back here, let me comment this one and let me bring this comment here and say update record. 24 00:02:04,080 --> 00:02:07,290 So let's see how we are going to update this one. 25 00:02:07,290 --> 00:02:10,800 So we bring in the student model on that. 26 00:02:10,800 --> 00:02:15,900 We are going to use find one and update as soon as I type in fine. 27 00:02:15,900 --> 00:02:24,750 I see all the method that I can use on that model and the one that I want is find one and update which 28 00:02:24,750 --> 00:02:31,020 is this one and next is you pass in the options or the configuration. 29 00:02:31,290 --> 00:02:33,360 The first one going to be the query. 30 00:02:33,630 --> 00:02:43,470 So let's find the student by name of John as that and a nest egg means pass in is a field that you want 31 00:02:43,470 --> 00:02:44,340 to update. 32 00:02:44,430 --> 00:02:48,600 So I want to update the age to 35. 33 00:02:49,020 --> 00:02:55,830 The NEST agreement going to be option like we saw in the documentation and then the first one going 34 00:02:55,830 --> 00:03:03,420 to be new to true meaning that we want to see the updated one on the fly as soon as we save it. 35 00:03:03,870 --> 00:03:12,330 So let's handle the premise then and then we have the student as the student, or you can make it as 36 00:03:12,360 --> 00:03:19,310 updated student and let me catch any error if there is going to be an error here also. 37 00:03:20,320 --> 00:03:22,460 All right, then. 38 00:03:22,460 --> 00:03:24,830 Let me move this one and let's see. 39 00:03:25,100 --> 00:03:27,320 So back to the terminal here. 40 00:03:27,620 --> 00:03:33,530 Let me clear the terminal and let me run the file again instead of 20 of the age. 41 00:03:33,530 --> 00:03:36,950 Now we have 30, meaning that it has been updated. 42 00:03:36,950 --> 00:03:43,550 Let's try to remove the new and let's see if you're going to see the updated one based on what we've 43 00:03:43,550 --> 00:03:44,150 learned. 44 00:03:44,660 --> 00:03:44,990 Okay. 45 00:03:45,050 --> 00:03:47,930 So now let me change the age to 40 years. 46 00:03:50,110 --> 00:03:50,770 Here we go. 47 00:03:50,770 --> 00:03:52,360 Back to the terminal here. 48 00:03:52,390 --> 00:03:55,570 Let me clear it and let me run it again. 49 00:03:55,840 --> 00:04:03,070 I could see that you couldn't get the updated one, but inside our DB, if you refresh it, we are going 50 00:04:03,070 --> 00:04:05,230 to see that it is 40. 51 00:04:05,960 --> 00:04:11,750 And you can see that we have it here, but we didn't see it as a response. 52 00:04:11,780 --> 00:04:15,270 That's why the new equipment is important. 53 00:04:15,290 --> 00:04:20,810 So let me bring back the new here and let me change this one to, let's say, 50 years. 54 00:04:20,959 --> 00:04:23,760 We also have another method for updating. 55 00:04:23,780 --> 00:04:28,820 So let me copy this one and comment it and the difference here. 56 00:04:28,820 --> 00:04:32,240 Can I be fine by ID and update? 57 00:04:32,390 --> 00:04:39,130 And this one finds only the ID, so find by I.D. and update. 58 00:04:39,140 --> 00:04:42,740 So here we pass in the ID as a student. 59 00:04:42,740 --> 00:04:46,480 So let's find the ID back to my campus here. 60 00:04:46,490 --> 00:04:52,370 I think I want to find a manual here so I'll copy the ID and back to my code. 61 00:04:52,370 --> 00:04:56,450 Here, let me replace it with that and then come on, separate it. 62 00:04:56,540 --> 00:04:58,220 Now back to the terminal. 63 00:05:00,080 --> 00:05:07,370 Let me run it again and let's see if I'm going to get Emanuel to be updated. 64 00:05:07,520 --> 00:05:11,330 And you can see that Emanuel Fair has been updated. 65 00:05:11,600 --> 00:05:12,170 All right. 66 00:05:12,170 --> 00:05:18,350 So these are the common methods you are going to use a lot find by ID and update more than the fine 67 00:05:18,350 --> 00:05:19,940 one and update.
