如何找到Rails部分的文件名？

In Rails 3, how do I find the file name of the partial that would be rendered by render 'foo'?

在Rails 3中,如何找到渲染'foo'渲染的局部文件名?

Just to be clear, you get two different results if you call render from within a controller, and render from within tags in a view.

为了清楚起见,如果从控制器中调用render,并从视图中的标记内进行渲染,则会得到两个不同的结果。

In a controller bar calling render 'foo' would result in rendering the file <project>/app/views/bar/foo.html.erb.

在调用render'foo'的控制器栏中,将导致呈现文件 /app/views/bar/foo.html.erb。

In a view e.g. <project>/app/views/bar/show.html.erb calling <% render 'foo' %> would result in including the partial <project>/app/views/bar/_foo.html.erb into the show.html.erb view. The partial is taken from the same directory as the view.

在视图中,例如 /app/views/bar/show.html.erb调用<%render'foo'%>会导致将部分 /app/views/bar/_foo.html.erb包含到show.html中.erb视图。部分取自与视图相同的目录。

And to make things a little more complex, if you put folder names into the render e.g. render 'shared/foo' this is relative to <project>/app/views.

如果您将文件夹名称放入渲染中,例如将事情变得更复杂一些,例如渲染'shared / foo'这是相对于 / app / views。

So:

Controller: render 'foo'              = <project>/app/views/<controller name>/foo.html.erb
            render 'shared/foo'       = <project>/app/views/shared/foo.html.erb
View:       <% render 'foo' %>        = _foo.html.erb in directory of view
            <% render 'shared/foo' %> = <project>/app/views/shared/_foo.html.erb

P.S. if you specify a different :format in your render command, then the html.erb needs to change accordingly (e.g. js.erb, js.coffee.erb, etc etc).

附:如果你在render命令中指定了另一种:format,那么html.erb需要相应地改变(例如js.erb,js.coffee.erb等)。
