Rails 3 - Restricting formats for action in resource routes

Question

I have a resource defined in my routes.

resources :categories

And I have the following in my Category controller:

  def sho         


        

Answer 1

You could do the following in your routes.rb file to make sure that only the show action is constrained to json or xml:

resources :categories, :except => [:show]
resources :categories, :only => [:show], :constraints => {:format => /(json|xml)/}

If this doesn't work you could try explicitly matching the action:

resources :categories, :except => [:show]
match 'categories/:id.:format' => 'categories#show', :constraints => {:format => /(json|xml)/}
