[API] Posts (for learning)

[API] Posts

The post resource should fulfill requirements below

• POST /api/posts | Create a post
• GET /api/posts | Get a listing of posts
• GET /api/posts/:id | Get details about a post
• PUT /api/posts/:id | Update a post
• DELETE /api/posts/:id | Delete a post

Generate a json post resource with title and body

Hint: phoenix doc

Spoiler

mix phoenix.gen.json Post posts title:string body:text

Then add route and migrate

Spoiler

Add the resource to your api scope in web/router.ex:

resources "/posts", PostController, except: [:new, :edit]

Remember to update your repository by running migrations:

$ mix ecto.migrate

Edit your json post resource as needed to fulfill requirements

Change ur route to be able to fulfill the requirements

Spoiler

In web/routes.ex, remove the except: [:new, :edit].

Try to use ur newly created json post resource by sending POST requests to your server api.

Spoiler

Send the following as body in Postman:

{
  "post": {
    "title": "First Post",
    "body": "Content"
  }
}

Tip: Download Postman.

Further notes:

In web/controllers/post_controller.ex:

def create(conn, %{"post" => post_params}) do

expects a POST request as:

{
  "post": {
    "title": "First Post",
    "body": "Content"
  }
}

in contrast to:

def create(conn, post_params) do

which expects a POST request as:

{
  "title": "First Post",
  "body": "Content"
}
