1 00:00:07,790 --> 00:00:13,790 Now that we are done with the user API creation, let's move to the account. 2 00:00:13,790 --> 00:00:16,020 So inside the controls. 3 00:00:16,040 --> 00:00:23,550 Now here is the account controller and we are done with the creation and then fetching all. 4 00:00:23,570 --> 00:00:31,760 So what we want to work on is to find a single account and this API is really important to us when you 5 00:00:31,760 --> 00:00:39,200 get to the front end because if you want to find a setting account with a transaction, we need this 6 00:00:39,200 --> 00:00:40,990 endpoint or controller. 7 00:00:41,000 --> 00:00:43,780 So let's see how we are going to get that one done. 8 00:00:43,790 --> 00:00:51,500 So first of all, we are going to find the account by it ID and you are going to find it inside the 9 00:00:51,500 --> 00:00:52,100 params. 10 00:00:52,130 --> 00:00:59,120 So let's check the endpoint for the account and here is the account collection folder and here is a 11 00:00:59,120 --> 00:00:59,840 single. 12 00:00:59,870 --> 00:01:04,190 When I hit send, it means that everything is working fine. 13 00:01:04,190 --> 00:01:08,300 So let's go to the controller and then implement the functionality. 14 00:01:08,300 --> 00:01:15,260 So first step is that find the ID from params. 15 00:01:16,250 --> 00:01:23,900 So if we console.log the red dot params dot id, so let's save it. 16 00:01:23,900 --> 00:01:27,230 And now let's see the ID that we are referring to. 17 00:01:27,230 --> 00:01:36,290 So let's hit send and you can see that I have the ID here, so now we can go ahead and then copy one 18 00:01:36,290 --> 00:01:37,430 of the accounts. 19 00:01:37,430 --> 00:01:45,170 So let's fetch all account and let's copy the ID for this account called Mom's Building Project. 20 00:01:45,350 --> 00:01:48,920 So inside a single here, I will provide it as that. 21 00:01:48,920 --> 00:01:53,930 And now I hit send and now I have the ID inside the terminal. 22 00:01:53,930 --> 00:01:58,790 So now I can go ahead and find the account by ID. 23 00:01:58,820 --> 00:02:01,010 So here we go. 24 00:02:01,010 --> 00:02:02,570 So I can go ahead. 25 00:02:02,570 --> 00:02:04,730 And then this structure, the ID. 26 00:02:04,760 --> 00:02:11,570 So const as ID is equal to rec dot params. 27 00:02:11,750 --> 00:02:12,620 Perfect. 28 00:02:13,040 --> 00:02:21,980 So next step is that let's find the account and it's equal to a weight and then the account model and 29 00:02:21,980 --> 00:02:26,780 find by ID and here I'll provide the ID. 30 00:02:26,810 --> 00:02:30,920 So next step is that let's send the response back to the user. 31 00:02:30,920 --> 00:02:42,650 So here let's remove this one and now let's provide status and you say is success and then the actual 32 00:02:42,650 --> 00:02:45,050 data is the account. 33 00:02:45,350 --> 00:02:51,440 So now let's check it out when we hit send, let's see and here we go. 34 00:02:51,650 --> 00:02:58,460 But upon fetching the account, I want to populate the transaction for this particular account. 35 00:02:58,490 --> 00:03:06,560 In that way we are going to use populates so here we can change the populate, but because for this 36 00:03:06,560 --> 00:03:15,740 one there is no nested ID, I can go ahead and use this format as transaction transaction. 37 00:03:15,830 --> 00:03:22,310 So now let's make the request to first single and let's see the response and here we go. 38 00:03:22,310 --> 00:03:28,700 So inside the front end, if you find a particular account, you'll be able to know the transaction 39 00:03:28,710 --> 00:03:35,720 about the account and we can go ahead and then filter out the transaction by the account type. 40 00:03:35,750 --> 00:03:41,000 So you can have a section for all expenses and then only for income. 41 00:03:41,000 --> 00:03:48,230 And we can do some mathematical operation to find the total expenses or total income or the total balance. 42 00:03:48,230 --> 00:03:53,720 So in the next video, let's go ahead and implement how we can update an account.
