How to execute :action before rendering its view using “render” in Rails?

Question

I understand that render :action only renders an action's view. But I was wondering.. Is there no easy way to execute the code in that action before its view is rendered?

Answer 1

如果你试图在两个不同的控制器中重用逻辑，为什么不把它的逻辑从当前的控制器中拉出来像一个辅助方法或类更可重用？

Answer 2

Yes, there is.

class TestolaController < ApplicationController
  def foo
    redirect_to :action => "bar"
  end

  def bar
    puts "in bar"
  end
end

Answer 3

  def foo
    bar
  end

  def bar
    puts "in bar"
  end
