Simple question about yield :layout for Rails 2.3 app

ruby-talk
1

I'm maintaining and old app. I'm seeing in the layouts they've used

    <body>
        <%= yield :layout %>
    </body>

rather than just a simple <%= yield %>

I'm guessing these are equivalent, but can someone give me a
history/explanation of the <%= yield :layout %> convention?

I can't seem to be able to find any mention of it in old docs.

Thanks

This isn't something thats been deprecated from rails, its also present in
4.1.7 and its very commonly used.

I can point you to the appropriate docs here:

I think you misunderstood my question.

I asked about the :layout symbol specifically, not the general yielding to
a specific block associated with content_for, i.e. <%= yield :head %>

The <%= yield :layout %> is not associated with a content_for and it is in
fact yielding to the view template, same as plain <%= yield %>
