Rails partials in controller

Question

I've got a code that almost repeats itself in three of my controllers and i was wondering: is there a way to render partials inside controllers? I'll clarify, i want to write the same piece of ruby code and render it in each one of the controllers. Anyone know a way to do that? thanks

I don't get your idea. Partials are part of the view logic and then you are asking for repeated code inside controllers. Can you put an example that clarify your question? — Pigueiras, Feb 27 '13 at 17:38

I'm very confused by your question; I don't see what it has to do with partials. However, if I understand correctly, what you have is something like.

class FooController < ApplicationController
  def my_method
  end
end

class BarController < ApplicationController
  def my_method
  end
end

class BazController < ApplicationController
  def my_method
  end
end

And you want to DRY it up by abstracting the my_method method to a single place. The solution is to define it on ApplicationController, which the other three controllers all inherit from.

There are two solutions, the module, and playing with the inheritance

Module

Define a module with your custom code and include it in your controllers

module MyCustomModule
  def method_1
    #code ...
  end

 def method_2
    #code ...
  end


  def method_2
    #code ...
  end
end

Then in your controllers :

class MyController < AplicationController
  include MyCustomModule
end

Inheritance

If you don't mind having all your controllers ending up with these methods, simply define them in the application controller

class ApplicationController < ActionController::Base
  # ...

  def method_1
    #code
  end

  # And so on ...
end
