Identify GET and POST parameters in Ruby on Rails

Question

What is the simplest way to identify and separate GET and POST parameters from a controller in Ruby on Rails, which will be equivalent to $_GET and $_POST variables in PHP?<

Answer 1

If you want to check the type of request in order to prevent doing anything when the wrong method is used, be aware that you can also specify it in your routes.rb file:

map.connect '/posts/:post_id', :controller => 'posts', :action => 'update', :conditions => {:method => :post} 

or

map.resources :posts, :conditions => {:method => :post} 

Your PostsController's update method will now only be called when you effectively had a post. Check out the doc for resources.
