如何在另一个控制器的方法中调用一个控制器的方法

Question

I want to call a method of one controller in another controller's method, and also pass parameters like below:

Controller A:

@var
def methodA
  update(@var)
end

Controller B:

def update(var)
  var1 = var
end

Is there any way to do this?

Answer 1

Why not define the shared method in ApplicationController instead and call it in both controllers as they each inherit it's methods. Like so:

ApplicationController:

class ApplicationController < ActionController::Base

  protected

  def update(var)
    var1 = var
  end
end

Other Controllers:

class SomeController < ApplicationController    
  def some_method()
    @var = 'something'
    update(@var)
  end
end


class SomeOtherController < ApplicationController    
   def some_method()
     @var = 'something'
     update(@var)
   end
 end
