1 00:00:01,020 --> 00:00:08,240 And to complete our register functionality, let's learn about schema instant's methods in Mongo's, 2 00:00:08,610 --> 00:00:10,320 so I'm going to navigate to the docs. 3 00:00:10,320 --> 00:00:12,810 In this case, we're looking for schemas. 4 00:00:13,290 --> 00:00:20,250 And if we take a look at the list, we see this instance methods and essentially what happens. 5 00:00:20,640 --> 00:00:25,240 Every document we create, we can have functions on them. 6 00:00:25,740 --> 00:00:28,800 So these are going to be instances, of course, of our schema. 7 00:00:29,130 --> 00:00:29,610 Correct. 8 00:00:29,940 --> 00:00:36,990 And the way we set up those functions, we go with the scheme and then methods and then whatever function 9 00:00:36,990 --> 00:00:37,380 you want. 10 00:00:37,860 --> 00:00:45,060 So essentially, once I create that user over here in the register, that user will have a function 11 00:00:45,360 --> 00:00:50,870 and you can probably already guess that will create a function that just generates that token. 12 00:00:51,180 --> 00:00:57,510 And of course, in that function, we'll pretty much have the same code and therefore we won't have 13 00:00:57,510 --> 00:01:02,510 to bother with that in the actual controller, in the register controller. 14 00:01:02,860 --> 00:01:08,790 And let's start somewhat silly where I want to go back to my model, the user one, and let's just go 15 00:01:08,790 --> 00:01:10,130 with user schema. 16 00:01:10,890 --> 00:01:13,470 So of course, that is the name that stays the same. 17 00:01:13,720 --> 00:01:18,070 Then we go with methods and then we'll just say get name. 18 00:01:18,480 --> 00:01:23,640 So let's imagine that we're just lazy getting the user name and we have multiple options. 19 00:01:24,000 --> 00:01:28,620 We can set it up as a sink or we can just set it up as a regular function. 20 00:01:28,650 --> 00:01:31,350 So in this case, we'll just go with the regular function. 21 00:01:31,360 --> 00:01:32,910 So no async keyword. 22 00:01:33,220 --> 00:01:40,320 But again, we do want to use this function keyword, not a function, because that way this will always 23 00:01:40,680 --> 00:01:45,570 point to our document and we get name simply what do I want to do? 24 00:01:45,810 --> 00:01:49,080 I want to return this dot and name. 25 00:01:49,380 --> 00:01:55,680 And now of course, we just want to go back to auth jazz and where we have user that name, let's just 26 00:01:55,680 --> 00:02:01,100 invoke, let's say user and we're going to be looking for get a name. 27 00:02:01,250 --> 00:02:02,580 So invoke this one. 28 00:02:02,910 --> 00:02:06,820 And now let's go to the postman and let's try to send it. 29 00:02:07,230 --> 00:02:08,580 So now get back. 30 00:02:08,820 --> 00:02:09,750 I'll send it. 31 00:02:10,139 --> 00:02:14,880 And because I wasn't careful, of course I didn't pay attention to my email. 32 00:02:15,180 --> 00:02:18,780 So of course I need to change it to John for Gmail dot com. 33 00:02:19,020 --> 00:02:21,810 And I can clearly see that I still have the name. 34 00:02:22,020 --> 00:02:29,460 So if I'll change this one around on your I say Ana and maybe I'll go with and add Gmail that come, 35 00:02:30,030 --> 00:02:32,880 then I'll still be able to access the name. 36 00:02:33,030 --> 00:02:38,800 And what that means is that we can generate a token using the instance method instead. 37 00:02:38,940 --> 00:02:46,050 So again, we're trying to keep all our logic in one place where we have the user schema instead of 38 00:02:46,050 --> 00:02:49,140 scattered around our controllers. 39 00:02:49,440 --> 00:02:56,640 And let's just fix everything back and say user name will stay with that for the time being. 40 00:02:56,640 --> 00:03:02,970 Of course we can cut it out and I think retype one more time from scratch just so we can get comfortable 41 00:03:03,270 --> 00:03:04,810 with JWT. 42 00:03:04,830 --> 00:03:10,130 Now, am I going to need the import here for the token anymore so I can definitely cut it out? 43 00:03:10,350 --> 00:03:12,180 I have my user awesome. 44 00:03:12,180 --> 00:03:16,450 And eventually I'll invoke a method that will get me that token. 45 00:03:16,560 --> 00:03:20,040 So now let me save off Jass back in the user. 46 00:03:20,040 --> 00:03:22,740 Of course, the name is not going to be get name. 47 00:03:23,160 --> 00:03:26,010 And you know, I'll just set up everything from scratch. 48 00:03:26,280 --> 00:03:29,130 I'll say user schema Lanegan. 49 00:03:29,130 --> 00:03:33,750 The syntax is methods and then we're looking for the function name. 50 00:03:33,900 --> 00:03:37,350 And in this case I'll call this create JWT. 51 00:03:37,680 --> 00:03:40,350 And again, it's going to be a simple function here. 52 00:03:40,650 --> 00:03:43,770 And as far as the logic will just return right away. 53 00:03:43,770 --> 00:03:48,570 JWT sign and of course in here I need to get the library. 54 00:03:48,870 --> 00:03:54,330 So let's go at JWT at the top and then JWT signed. 55 00:03:54,540 --> 00:03:58,980 And again, remember in the function we can access the document. 56 00:03:58,980 --> 00:03:59,370 How. 57 00:03:59,580 --> 00:04:01,050 Well, by using this. 58 00:04:01,050 --> 00:04:01,500 Correct. 59 00:04:01,650 --> 00:04:08,220 And as far as the payload, again, I'm going to go with user I.D. then I'll set it equal to this and 60 00:04:08,220 --> 00:04:09,270 underscore already. 61 00:04:09,600 --> 00:04:16,140 So this points to the document and then we're going to go with comma name and then we'll just go with 62 00:04:16,320 --> 00:04:17,100 this, that name. 63 00:04:17,370 --> 00:04:24,960 And again, we'll just create a little bit where I say JWT secret and that as far as the expression 64 00:04:24,960 --> 00:04:31,860 again, we'll keep it at thirty days so expires and we'll set equal to thirty days. 65 00:04:32,100 --> 00:04:34,640 So now if I go back to all things. 66 00:04:34,690 --> 00:04:35,040 Yes. 67 00:04:35,340 --> 00:04:38,850 I simply want to call create JWT. 68 00:04:39,000 --> 00:04:39,490 That's it. 69 00:04:39,510 --> 00:04:40,710 That's all we have to do. 70 00:04:41,040 --> 00:04:48,030 So once we create the user of course we have that instant method and here I can just say token and I'm 71 00:04:48,030 --> 00:04:49,050 going to go user. 72 00:04:49,380 --> 00:04:54,720 And of course the name of the method is Create and JWT. 73 00:04:54,960 --> 00:04:59,490 We invoke it and now of course, we can go back to our postman. 74 00:05:00,090 --> 00:05:06,450 We already have one, Anna, and let's just change the name so we can see how that works, maybe with 75 00:05:06,450 --> 00:05:10,110 Peter and I'll set it here as Peter as well. 76 00:05:10,350 --> 00:05:15,630 And then once we send, of course, now I have the Peter as well as a token. 77 00:05:15,660 --> 00:05:19,710 And of course, that means that everything works successfully. 78 00:05:20,010 --> 00:05:22,890 We're done with our register controller. 79 00:05:23,100 --> 00:05:29,370 And in the process, we learned about hashing the passwords, setting up the mouse middleware, as well 80 00:05:29,370 --> 00:05:31,890 as the instance methods on a schema.
