Feed Follows

Aside from just adding new feeds to the database, users can specify which feeds they want to follow. This will be important later when we want to show users a list of posts from the feeds they follow.

Add support for the following endpoints, and update the "create feed" endpoint as specified below.

What is a "feed follow"?

A feed follow is just a link between a user and a feed. It's a many-to-many relationship, so a user can follow many feeds, and a feed can be followed by many users.

Creating a feed follow indicates that a user is now following a feed. Deleting it is the same as "unfollowing" a feed.

It's important to understand that the ID of a feed follow is not the same as the ID of the feed itself. Each user/feed pair will have a unique feed follow id.

Create a feed follow

Endpoint: POST /v1/feed_follows

Requires authentication

Example request body:

{
  "feed_id": "4a82b372-b0e2-45e3-956a-b9b83358f86b"
}

Example response body:

{
  "id": "c834c69e-ee26-4c63-a677-a977432f9cfa",
  "feed_id": "4a82b372-b0e2-45e3-956a-b9b83358f86b",
  "user_id": "0e4fecc6-1354-47b8-8336-2077b307b20e",
  "created_at": "2017-01-01T00:00:00Z",
  "updated_at": "2017-01-01T00:00:00Z"
}

Delete a feed follow

Endpoint: DELETE /v1/feed_follows/{feedFollowID}

Get all feed follows for a user

Endpoint: GET /v1/feed_follows

Requires authentication

Example response:

[
  {
    "id": "c834c69e-ee26-4c63-a677-a977432f9cfa",
    "feed_id": "4a82b372-b0e2-45e3-956a-b9b83358f86b",
    "user_id": "0e4fecc6-1354-47b8-8336-2077b307b20e",
    "created_at": "2017-01-01T00:00:00Z",
    "updated_at": "2017-01-01T00:00:00Z"
  },
  {
    "id": "ad752167-f509-4ff3-8425-7781090b5c8f",
    "feed_id": "f71b842d-9fd1-4bc0-9913-dd96ba33bb15",
    "user_id": "0e4fecc6-1354-47b8-8336-2077b307b20e",
    "created_at": "2017-01-01T00:00:00Z",
    "updated_at": "2017-01-01T00:00:00Z"
  }
]

Automatically create a feed follow when creating a feed

When a user creates a new feed, they should automatically be following that feed. They can of course choose to unfollow it later, but it should be there by default.

The response of this endpoint should now contain both entities:

{
  "feed": { the feed object },
  "feed_follow": { the feed follow object }
}

Test

As always, test all of your endpoints and make sure they work. Additionally, make sure that they return the proper error codes when they receive invalid inputs.
