Controller: 控制器：
layout false, only: [:method_name]
this is very useful when you using render_to_string 这在使用render_to_string时非常有用

If you do not want to specify the view to use. 如果您不想指定要使用的视图。
Rails is smart enough to know which view template to use based on the Controller Action you're on. Rails非常聪明，可以根据您所在的Controller Action知道要使用哪个视图模板。
For example, if you're on the show action of the TabellesController you wouldn't need to specify render "tabelle/show" in your Controller Action because Rails will already assume that and will automatically try to render the file in app/views/tabelles/show.html.erb . 例如，如果您正在使用TabellesController的show动作，则不需要在Controller Action中指定render "tabelle/show" ，因为Rails已经假设并且将自动尝试在app/views/tabelles/show.html.erb呈现文件app/views/tabelles/show.html.erb 。
So if you're sticking with all of those defaults then you can just use the following to render without the typical layout template: 因此，如果您坚持使用所有这些默认值，那么您可以使用以下内容进行渲染， 而无需使用典型的布局模板：
def show
# Other stuff in your Controller Action.
render layout: false
end
This will render app/views/tabelles/show.html.erb but without the layout template automatically. 这将呈现app/views/tabelles/show.html.erb但不会自动显示布局模板。
Noice. 在降噪。
