ruby-on-rails - 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

如果您尝试在两个不同的控制器中重用逻辑，为什么不将该逻辑从其当前控制器中拉出到更可重用的东西中，例如辅助方法或类？

Answer 2

就在这里。

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
