1 00:00:00,300 --> 00:00:07,710 And once we have our scheme and model in place before we can start setting up any kind of functionality, 2 00:00:08,130 --> 00:00:09,450 of course we need to have data. 3 00:00:10,080 --> 00:00:16,890 Otherwise, how are you going to set up any kind of filtering if you have no product in a database? 4 00:00:17,280 --> 00:00:19,230 And effectively, we have two choices. 5 00:00:19,620 --> 00:00:28,440 You either can set up a postcard and then just manually add them, or a better approach is just to automate 6 00:00:28,440 --> 00:00:33,900 this and essentially just have some kind of list and pass it on to your database. 7 00:00:34,260 --> 00:00:40,710 Now, lucky for you, if you take a look at our project, you'll notice the product, Jason. 8 00:00:41,590 --> 00:00:48,350 And essentially, this is just a list of products just so we can start working on the filter functionality 9 00:00:48,760 --> 00:00:56,890 and the only thing we need to do is set up populated areas where we will dynamically add all of these 10 00:00:56,890 --> 00:00:58,770 values to our database. 11 00:00:59,050 --> 00:01:05,890 So instead of going the manual route where one by one we have them will right away just add them to 12 00:01:05,890 --> 00:01:09,990 our database by actually invoking the populate address. 13 00:01:10,420 --> 00:01:16,170 And the way it's going to look like we're going to go over here, will first grab our data entry. 14 00:01:16,450 --> 00:01:20,830 So let's say over here, dot envy, then we want to go with Canford. 15 00:01:21,220 --> 00:01:25,930 And then what's really interesting, that we need to have another connection. 16 00:01:26,170 --> 00:01:30,730 So, yes, we have one for objets, of course, that still stays the same. 17 00:01:30,730 --> 00:01:37,540 But since we want to connect to the database one more time, we'll have to grab that connect function 18 00:01:37,540 --> 00:01:38,170 as well. 19 00:01:38,680 --> 00:01:42,910 And here is going to go to connect the web. 20 00:01:43,060 --> 00:01:48,220 Of course, that is coming from where that is coming from our DB folder. 21 00:01:48,230 --> 00:01:48,630 Correct. 22 00:01:48,940 --> 00:01:53,740 So we go here with DB and then more specifically, connect, not the first thing we want to grab. 23 00:01:54,070 --> 00:01:57,100 Then we want to grab the model and you'll see why. 24 00:01:57,430 --> 00:02:00,450 And we just need to come up with a name and I'm going to go good product. 25 00:02:00,850 --> 00:02:08,259 And then of course, we are requiring that it is coming from the models and more specifically, product. 26 00:02:09,100 --> 00:02:15,070 And then lastly, I want those Jason products, because that's the data that I'm going to be passing 27 00:02:15,070 --> 00:02:16,060 on to the database. 28 00:02:16,450 --> 00:02:18,580 So here we need to come up with a name. 29 00:02:19,000 --> 00:02:24,630 In this case, I think I'm going to go get some products and we'll set it equal to require and where 30 00:02:24,670 --> 00:02:27,120 the file is actually sitting right next to us. 31 00:02:27,370 --> 00:02:32,700 So I'll just go with Forward Slash and then we're looking for product Gersen. 32 00:02:33,010 --> 00:02:39,190 And once we have all of this in place, we want to set up that start function one more time. 33 00:02:39,470 --> 00:02:42,460 Or in this case, of course, we're not going to be setting up that. 34 00:02:42,460 --> 00:02:50,350 Listen, we simply want to connect through the database and then use the model to automatically add 35 00:02:50,350 --> 00:02:55,690 those JSON products, the one that we have in file to our database. 36 00:02:56,050 --> 00:02:59,740 And the way it's going to look like we're going to go over here with Consed and start. 37 00:03:00,660 --> 00:03:07,160 And we'll set it equal to a sink in here, will set up another try catch so. 38 00:03:07,550 --> 00:03:11,840 So let's go try to catch and of course, eventually we'll invoke it here as well. 39 00:03:12,300 --> 00:03:15,630 And then I want to go with my white van. 40 00:03:15,640 --> 00:03:22,740 We want to pass in the corner, Debbie, and of course, inside of Debbie will pass in the process that 41 00:03:22,860 --> 00:03:25,160 the envy and of course, are variable. 42 00:03:25,170 --> 00:03:28,730 So mango and underscore you are right. 43 00:03:29,160 --> 00:03:35,780 And just because I want to see whether we're going to get some weird bugs, I'm also going to type in 44 00:03:35,790 --> 00:03:37,170 a catch a log. 45 00:03:38,070 --> 00:03:44,040 So go with Lugg and then we're going to be looking for the error and once we have all this in place, 46 00:03:44,310 --> 00:03:46,170 we can at least try the connection. 47 00:03:46,390 --> 00:03:48,300 Now, there's still some code that's missing. 48 00:03:49,080 --> 00:03:50,850 We'll get to it in another time. 49 00:03:51,130 --> 00:03:57,450 So, first of all, I want to do is stop the server over here and we just want to go. 50 00:03:57,690 --> 00:04:00,670 We have to start invoke it online. 51 00:04:00,700 --> 00:04:02,730 In this case, I'm not looking for an old man. 52 00:04:03,000 --> 00:04:04,980 I simply go with node. 53 00:04:05,220 --> 00:04:07,130 And then, of course, I'm looking for to find him. 54 00:04:07,500 --> 00:04:11,340 So since I'm already in a star, I just need to write populate. 55 00:04:11,790 --> 00:04:18,660 And then once we run it, if our connection again is successful, we shouldn't see any errors in a console. 56 00:04:19,050 --> 00:04:25,020 Now, if you want to help yourself out, of course, you can just type your log and let's just say success 57 00:04:25,020 --> 00:04:26,390 or something along those lines. 58 00:04:26,760 --> 00:04:31,350 So let's say here success and point. 59 00:04:31,560 --> 00:04:32,970 Let's say one more time again. 60 00:04:32,970 --> 00:04:33,720 Let's stop it. 61 00:04:33,990 --> 00:04:39,950 And if you remember from tutorial, in order to go back to the last command, we simply press arrow 62 00:04:39,960 --> 00:04:41,550 key up or down markers. 63 00:04:41,790 --> 00:04:43,940 We're going to press it down and check it out. 64 00:04:44,100 --> 00:04:48,880 Now, of course, we have success, so we successfully connected to the database. 65 00:04:48,900 --> 00:04:54,350 Now, if I want to check out the error or coming out of the data entry, stop the server one more time. 66 00:04:54,630 --> 00:04:57,240 Sorry about the detour, but these things are important. 67 00:04:57,480 --> 00:05:03,720 And then once we run out, of course, we're not successful connecting to the database because the you 68 00:05:03,720 --> 00:05:05,920 are our primer is not provided. 69 00:05:06,060 --> 00:05:06,510 Awesome. 70 00:05:06,600 --> 00:05:10,740 So let me comment on the data entry and clear everything. 71 00:05:11,040 --> 00:05:16,220 And once we have successfully connected to our database, there's two things that I want to do. 72 00:05:16,560 --> 00:05:24,150 First, I want to remove all the products that are currently there and then I want to use the create 73 00:05:24,420 --> 00:05:26,600 and just pass in the JSON product. 74 00:05:26,970 --> 00:05:33,270 So if you remember in a previous setup and I think I'm just going to go for final and let me look for 75 00:05:33,270 --> 00:05:39,210 controllers and tasks, notice here this create we passed here a object. 76 00:05:39,540 --> 00:05:41,760 Correct, when we were creating that task. 77 00:05:42,240 --> 00:05:45,640 Now what we can also do is pass in the array. 78 00:05:45,930 --> 00:05:53,220 So if you take a look at the product and I'm sorry this one products, Jason, you'll notice that this 79 00:05:53,220 --> 00:05:55,280 is an array at the end of the day. 80 00:05:55,680 --> 00:06:02,400 And since this is an array, what I can do, I can just pass this thing into the dot create. 81 00:06:02,730 --> 00:06:09,210 And by doing so, of course, I'll add all of these products to our database. 82 00:06:09,400 --> 00:06:10,290 So let's try it out. 83 00:06:10,680 --> 00:06:12,210 Let me navigate here. 84 00:06:12,210 --> 00:06:15,030 The populate one have the adjacent products. 85 00:06:15,370 --> 00:06:16,430 I'm in good shape. 86 00:06:16,650 --> 00:06:21,120 So now let me go below the weight board before the success. 87 00:06:21,540 --> 00:06:26,040 And in here I want to go with a weight now, not waiting for the actual response. 88 00:06:26,460 --> 00:06:33,590 And I want to go with my model because model has all those functions and then we want to go with delete 89 00:06:33,630 --> 00:06:34,050 many. 90 00:06:34,300 --> 00:06:37,530 So now I just want to remove all the products that are currently there. 91 00:06:37,800 --> 00:06:40,350 Of course, in our case there are no products. 92 00:06:41,100 --> 00:06:47,730 I'm just making sure that later, if you want to use it, then whatever gibberish you added or whatever 93 00:06:47,730 --> 00:06:51,950 data you currently have, you just remove it and then you start from scratch. 94 00:06:52,260 --> 00:06:53,640 This is technically optional. 95 00:06:53,760 --> 00:06:54,540 You don't want to do it. 96 00:06:54,750 --> 00:06:55,500 You don't have to. 97 00:06:55,500 --> 00:07:01,920 But my guess, I always like to start with scratch and the line we want to go with a wait and then product 98 00:07:02,580 --> 00:07:05,290 product and then I remember the function create. 99 00:07:05,610 --> 00:07:11,220 So now we're just dynamically creating a bunch of product by passing in adjacent products. 100 00:07:11,400 --> 00:07:14,520 So all we have to do here we go with Jason product. 101 00:07:15,340 --> 00:07:20,590 And now let's try it one more time and then, of course, we'll double check in our application zone 102 00:07:20,590 --> 00:07:26,680 here, going to go back to my console and then I want to go with Nold and populate. 103 00:07:26,890 --> 00:07:31,480 And if I see the success, then I know that I'm heading in the right direction. 104 00:07:31,720 --> 00:07:34,330 So now let me just go back to my Atlas one. 105 00:07:34,660 --> 00:07:35,890 Let me refresh. 106 00:07:36,220 --> 00:07:44,770 And now where I have my collections, I should have more values and effectively I have the story API. 107 00:07:44,830 --> 00:07:45,280 Awesome. 108 00:07:45,550 --> 00:07:50,600 And in here I have, of course, all the products and I'm not sure how many I set up. 109 00:07:50,770 --> 00:07:55,310 It really doesn't matter if you see these products added to your database. 110 00:07:55,540 --> 00:08:00,190 Now, of course, we can start finally setting up our filter functionality. 111 00:08:00,820 --> 00:08:06,980 And while we're still on topic, actually, no, there is a method by the name of it. 112 00:08:07,480 --> 00:08:10,060 Now, why that would be useful in our case because. 113 00:08:10,060 --> 00:08:11,380 Well, let's think about it. 114 00:08:11,860 --> 00:08:13,780 So we have our popular address. 115 00:08:14,200 --> 00:08:19,720 If we're successful, then we might as well just terminate the whole process, correct? 116 00:08:19,980 --> 00:08:22,780 I mean, we don't need this file to be running. 117 00:08:23,320 --> 00:08:26,140 And if there is an error, then again, we'll exit. 118 00:08:26,380 --> 00:08:28,630 But maybe we error code. 119 00:08:29,020 --> 00:08:34,840 And the way we set up the process that exit is simply by navigating through the start here. 120 00:08:35,110 --> 00:08:42,789 And then probably right after the success, we'll set up a process then that is that global variable 121 00:08:42,789 --> 00:08:43,809 that we have access to. 122 00:08:44,070 --> 00:08:47,100 Then we go with exit and that's the method name. 123 00:08:47,290 --> 00:08:54,520 And that if we pass in zero, that just means that everything went well and we just exiting the process. 124 00:08:54,840 --> 00:09:01,150 However, if I take the exit method and pass it in and of course in this case, since I'm running it 125 00:09:01,150 --> 00:09:07,920 in the cache, I want to pass in error code, I'll pass in one and then let's do it one more time. 126 00:09:07,930 --> 00:09:11,170 I'll clear everything and I'll not start out with an error. 127 00:09:11,410 --> 00:09:14,620 But let's just go here with node populate. 128 00:09:14,860 --> 00:09:20,460 And now you'll notice that once we're successful, we actually exit the process. 129 00:09:20,470 --> 00:09:20,750 Why? 130 00:09:20,750 --> 00:09:22,930 Well, because we have process, not exit. 131 00:09:23,100 --> 00:09:26,470 And of course, the code in this case that we passed in is zero. 132 00:09:26,630 --> 00:09:32,980 And if you want to double check your data, just navigate back to the atlas and you'll see that all 133 00:09:32,980 --> 00:09:35,770 your product data is still there.
