从另一个控制器渲染控制器操作

Question

我认为代码更明确

选项A.

class RedirectController < ApplicationController
  def index
    redirect_to :controller => 'posts', :action => 'show', :id => 1
    # it works
  end
end

选项B.

class RedirectController < ApplicationController
  def index
    render :controller => 'posts', :action => 'show', :id => 1
    # it doesn't work
  end
end

(B)可以在另一个控制器中加载另一个动作吗？(而不只是视图)怎么样？谢谢

Answer 1

嗨尝试render 'posts/show'或render :template => 'posts/show'

Answer 2

只需渲染模板即可

def index
  render 'posts/show'
end

这个也可以用

def index
  render template: 'posts/show'
end

如果你想以其他布局渲染

def index
  render template: 'posts/show', layout: 'different_layout' 
end
