Group Work

tweedr is pivoting to become a social fintech company. Users can now send payments to each other.

A payment is a join table between two users.

sender_id	recipient_id	amount
2	4	1600
8	5	12
6	4	1

You will split the work between two people. One person will write model methods, the other will write controllers and views. DO NOT WORK ON THE SAME FILE we have not covered the git conflicts that will arise if two people work on the same file.

How to start

Decide on one of the apps you will work on.

Add the above functionality.

1. the DB model methods

db.payments.getUserPayments( recipient_id, (error, payments) => { ...
db.payments.getUserPayments( sender_id, (error, payments) => { ...

Gets an array of payments for a given id:

let recipient_id = 4;

...

// payments should look like this
const payments = [
  {
    sender_id : 2,
    recipient_id : 4,
    amount : 1600
  }
];

db.payments.getPaymentTotalByRecipient( recipient_id, (error, total) => { ...

let recipient_id = 4;
...

// total should be 1601

db.payments.getPaymentTotalBySender( sender_id, (error, total) => { ...

let sender_id = 8;
...

// total should be 8

2. controllers and views

Create the controllers and views to create a new payment, and show each payment.

/ should show the total you have sent and recieved. Use the db methods to show that number.
