Turn off layout for one of action
提问by Antiarchitect
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:
我的情况： ReportsController 的查看操作应该呈现纯 html，而不是作为文件（在浏览器中查看并保存）。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任何布局。但在此控制器布局的其他操作中，应保持不变。仅适用于关闭整个控制器，如下所示：
ReportsController < ApplicationController
layout false
But that doing it wrong :( for all the actions I tried to use something like this in action:
但是这样做是错误的:(对于我试图在行动中使用这样的所有操作：
def view
@report = Report.new(params[:report])
unless @report.valid?
render :action => 'new' and return
else
render :layout => false
end
end
What should I do?
我该怎么办？

In the respond block, add layout: false.
在响应块中，添加layout: false.
For example:
例如：
respond_to do |format|
format.html { render :layout => false } # your-action.html.erb
end

If you want to get a non-standard template, with no layout you can use:
如果你想得到一个非标准的模板，没有布局，你可以使用：
def non_rest
render template: 'layouts/something_new', layout: false
end
