How to handle multiple HTTP methods in the same Rails controller action

Question

Let\'s say I want to support both GET and POST methods on the same URL. How would I go about handling that in a rails controller action?

Answer 1

I would say, the best way is to create separate actions in the controller and state them in routes.

# config/routes.rb
...
get '/my_action' => 'my#my_action_get'
post '/my_action' => 'my#my_action_post'
...

# app/controllers/my_controller.rb
...
def my_action_get
  # do stuff like listing smth
end

def my_action_post
  # do other stuff
end

In fact, the same logic is used by Rails by default: index and create actions are both called by requests sent to the same paths (e.g. /articles), however, they have different request methods: GET /articles request is redirected to the index action and lists all articles, and POST /articles is redirected to the create action and creates a new article.
