关闭布局以执行一项操作 [英] Turn off layout for one of action

问题描述

我的情况: ReportsController的查看操作应呈现纯html，但不能呈现为文件(在浏览器中查看并在之后保存).因此，对于渲染，我使用视图模板view.html.erb，并且我需要关闭此操作的所有布局.但是在此控制器的其他操作中，布局应保持不变. 只能对整个控制器关闭，如下所示:

My situation: View action of ReportsController should render pure html, but not as a file (to view it in browser and save it after). So for rendering I use view template view.html.erb and i neet to turn off any layouts for this action. But in other actions of this controller layouts should stay untouched. Works only turning off for whole controller like this:

ReportsController < ApplicationController
  layout false

但是那做错了:(对于所有动作 我试图在操作中使用类似这样的东西:

But that doing it wrong :( for all the actions I tried to use something like this in action:

def view      
  @report = Report.new(params[:report])
  unless @report.valid?
    render :action => 'new' and return
  else
    render :layout => false     
  end   
end

我该怎么办?

推荐答案

尝试一下:

ReportsController < ApplicationController
  layout false
  layout 'application', :except => :view
