如何在提交表单时指定要呈现的布局并且验证失败？

In my app, new and edit actions of a controller should render different templates rather than the default layout like the following (it is not a normal rails app but an engine though).

在我的应用程序中，控制器的新动作和编辑动作应该呈现不同的模板，而不是像下面的默认布局（它不是普通的rails应用程序，而是引擎）。

module Blorgh
  class ArticlesController < ApplicationController

    layout Blorgh.config.layout # Configured in initializer

    ...

    # GET /articles/new
    def new
      @article = Article.new
      render :new, layout: "blorgh/new"
    end

    # GET /articles/1/edit
    def edit
      render :edit, layout: "blorgh/edit"
    end

    ...
  end
end

It works as expected, but when validation failed on POST create or PATCH update action via submitting a form in new or edit page, they are rendered with the default layout.

它按预期工作，但是当通过在新页面或编辑页面中提交表单在POST创建或PATCH更新操作上验证失败时，它们将使用默认布局呈现。

How to specify the layout in this case?

在这种情况下如何指定布局？

The way to do it is the same as in new and edit actions:

这样做的方法与新操作和编辑操作相同：

def update
  # ...
  render :edit, layout: 'blorgh/edit'
end

def create
  # ...
  render :new, layout: 'blorgh/new'
end

BTW, in your new and edit actions, you don't have to indicate template to render manually. It's ok if you have:

顺便说一句，在新的和编辑操作中，您不必指定要手动渲染的模板。没关系，如果你有：

def new
  # ...
  render layout: 'blorgh/new'
end

def edit
  # ...
  render layout: 'blorgh/edit'
end
