1 00:00:01,280 --> 00:00:02,656 ‫This video will be the first 2 00:00:02,656 --> 00:00:05,690 ‫of the four CRUD operation videos. 3 00:00:05,690 --> 00:00:09,363 ‫So this first one is about creating new documents. 4 00:00:10,720 --> 00:00:13,310 ‫But before we start creating new documents, 5 00:00:13,310 --> 00:00:16,730 ‫let me actually address a concern that you might be having. 6 00:00:16,730 --> 00:00:18,240 ‫So maybe you're wondering, 7 00:00:18,240 --> 00:00:21,540 ‫why are we actually doing all this stuff in a terminal? 8 00:00:21,540 --> 00:00:24,770 ‫And how does this relate to our Express application 9 00:00:24,770 --> 00:00:26,740 ‫that we built in the last section? 10 00:00:26,740 --> 00:00:29,100 ‫Well, the answer for that is that right now, 11 00:00:29,100 --> 00:00:32,383 ‫I want you to learn the absolute fundamentals of MongoDB, 12 00:00:32,383 --> 00:00:35,240 ‫without the context of any application. 13 00:00:35,240 --> 00:00:38,660 ‫So really, completely outside of Node.js. 14 00:00:38,660 --> 00:00:40,900 ‫Because in theory, we could us MongoDB 15 00:00:40,900 --> 00:00:43,730 ‫with any other language or any other framework. 16 00:00:43,730 --> 00:00:45,900 ‫It doesn't have to be with Node.js, 17 00:00:45,900 --> 00:00:48,020 ‫and so I think it's actually a good idea 18 00:00:48,020 --> 00:00:50,980 ‫to learn MongoDB standing completely on its own, 19 00:00:50,980 --> 00:00:53,640 ‫without the context of any other language. 20 00:00:53,640 --> 00:00:54,473 ‫Okay? 21 00:00:54,473 --> 00:00:56,590 ‫Later on, we will of course connect 22 00:00:56,590 --> 00:00:59,260 ‫a MongoDB database with our application, 23 00:00:59,260 --> 00:01:00,520 ‫so that in the next section, 24 00:01:00,520 --> 00:01:03,070 ‫we can then actually start working with databases 25 00:01:03,070 --> 00:01:05,350 ‫inside of our Express application. 26 00:01:05,350 --> 00:01:06,680 ‫And by then we will use 27 00:01:06,680 --> 00:01:09,610 ‫a MongoDB driver just for Node Express, 28 00:01:09,610 --> 00:01:11,720 ‫so that we can use our JavaScript language 29 00:01:11,720 --> 00:01:14,790 ‫to interact with our MongoDB database. 30 00:01:14,790 --> 00:01:15,623 ‫All right? 31 00:01:15,623 --> 00:01:18,830 ‫But for now, let's just learn MongoDB without any of that. 32 00:01:18,830 --> 00:01:19,780 ‫All right? 33 00:01:19,780 --> 00:01:22,380 ‫So in the last lecture, we created a new database. 34 00:01:22,380 --> 00:01:24,950 ‫A new collection inside, called tours, 35 00:01:24,950 --> 00:01:27,430 ‫and then one new document in there. 36 00:01:27,430 --> 00:01:28,263 ‫Right? 37 00:01:28,263 --> 00:01:29,360 ‫Remember that? 38 00:01:29,360 --> 00:01:31,730 ‫And to do that, we used insert 1. 39 00:01:31,730 --> 00:01:32,830 ‫Remember that? 40 00:01:32,830 --> 00:01:34,460 ‫But now, let's actually create 41 00:01:34,460 --> 00:01:36,980 ‫two documents at the same time. 42 00:01:36,980 --> 00:01:38,720 ‫So that works like this. 43 00:01:38,720 --> 00:01:43,720 ‫db, with just again, the current database, then .tours, 44 00:01:44,020 --> 00:01:45,700 ‫which is the collection where we want 45 00:01:45,700 --> 00:01:49,053 ‫to add our new documents, and then .insertMany. 46 00:01:51,640 --> 00:01:52,473 ‫Okay? 47 00:01:52,473 --> 00:01:56,003 ‫And insertMany is gonna accept an array of multiple objects. 48 00:01:56,900 --> 00:01:59,143 ‫So an array, and then close it. 49 00:02:00,210 --> 00:02:02,500 ‫So an empty object, and that may actually 50 00:02:02,500 --> 00:02:05,459 ‫put the second empty object here also already, 51 00:02:05,459 --> 00:02:08,883 ‫and so all we need to do is to fill up these objects. 52 00:02:10,030 --> 00:02:13,713 ‫So name, this one is called The Sea Explorer. 53 00:02:17,070 --> 00:02:21,140 ‫It has a price of 497, and a rating of 4.8. 54 00:02:27,030 --> 00:02:28,703 ‫And then the next object. 55 00:02:30,560 --> 00:02:35,560 ‫Let's give it a name of The Snow Adventurer. 56 00:02:38,210 --> 00:02:42,070 ‫Which is one of the other nine tours that we have. 57 00:02:42,070 --> 00:02:46,283 ‫Then the price is a bit more expensive, 997. 58 00:02:48,030 --> 00:02:51,020 ‫And the rating is 4.9. 59 00:02:51,020 --> 00:02:53,600 ‫And actually, let's add another field here. 60 00:02:53,600 --> 00:02:55,700 ‫So, remember from the intro lecture 61 00:02:55,700 --> 00:02:59,600 ‫how I said that MongoDB documents are very flexible. 62 00:02:59,600 --> 00:03:03,310 ‫And so they do not all have to have the same structure. 63 00:03:03,310 --> 00:03:04,143 ‫Okay? 64 00:03:04,143 --> 00:03:06,790 ‫So we can have different fields in different documents. 65 00:03:06,790 --> 00:03:09,253 ‫And so let's add the difficulty here. 66 00:03:13,690 --> 00:03:16,100 ‫And set this one to easy. 67 00:03:16,100 --> 00:03:17,040 ‫Okay? 68 00:03:17,040 --> 00:03:19,440 ‫So that's it, let's hit return here. 69 00:03:19,440 --> 00:03:22,390 ‫And so we inserted two new documents, 70 00:03:22,390 --> 00:03:25,280 ‫and here we see the IDs that they got. 71 00:03:25,280 --> 00:03:26,940 ‫So these two auto-generated 72 00:03:26,940 --> 00:03:29,325 ‫unique identifiers for each of them. 73 00:03:29,325 --> 00:03:30,390 ‫Okay? 74 00:03:30,390 --> 00:03:35,370 ‫Now just to make sure, remember make db.tours.find, 75 00:03:38,350 --> 00:03:41,490 ‫and here indeed, we now have our three tours. 76 00:03:41,490 --> 00:03:43,780 ‫So that's the one we created in the last lecture, 77 00:03:43,780 --> 00:03:46,190 ‫and then the two that we just created. 78 00:03:46,190 --> 00:03:47,290 ‫Okay? 79 00:03:47,290 --> 00:03:49,320 ‫So that's actually it for this lecture, 80 00:03:49,320 --> 00:03:52,670 ‫just to recap, we used the insertMany function 81 00:03:52,670 --> 00:03:56,050 ‫to pass in an array of two objects, 82 00:03:56,050 --> 00:03:59,267 ‫or two documents that we wanted to create. 83 00:03:59,267 --> 00:04:00,400 ‫Okay? 84 00:04:00,400 --> 00:04:03,150 ‫So that's all I had for this one. 85 00:04:03,150 --> 00:04:05,500 ‫In the next one, we will then learn how to do 86 00:04:05,500 --> 00:04:09,220 ‫some advanced queries to search for data in our database. 87 00:04:09,220 --> 00:04:12,613 ‫So that's an exciting one, so let's move on immediately.
