Overriding layout causes empty response with content_for


#1

Hi,

I’m trying to pinpoint what the issue might be here. In a controller
that has the appropriate layout (layouts/controller.html.erb), if I try
to override the layout to the ‘application’ layout only for certain
actions, those actions do get rendered with the application layout…
Like this:

layout ‘application’, :only => :new

The ‘new’ action renders fine, but now the other actions don’t render at
all!

No error or anything, just an empty response. I’ve tried renaming the
layout files to see if an error shows up, and no error (so no layout is
being picked up).

On my views I have content_for, so since nothing is yielding those
contents, nothing shows up. If I put something outside a content_for, it
does show up (without a layout of course).

If I explicitly render the layout on the action, it works, like so:

render :layout => ‘somelayout’

So what’s the deal here?

Thanks in advance!

I would try to explicitly specify the layout for the other actions. If
you
read the docs, you can sort of infer that no layout will be applied if
you
explicitly apply a layout to some actions:
http://api.rubyonrails.org/classes/ActionController/Layout/ClassMethods.html

“This will assign “weblog_standard” as the WeblogController’s
layouthttp://api.rubyonrails.org/classes/ActionController/Layout/ClassMethods.html#M000301except
for the
rss action, which will not wrap a
layouthttp://api.rubyonrails.org/classes/ActionController/Layout/ClassMethods.html#M000301around
the rendered view.”

Not sure that’s the right answer – just offering.

After unsuccessfully trying an after_filter to do the render, I did
found out that it is rendering with render_with_no_layout… I was
trying to avoid having an explicit render on every action, and now with
your comment as I re-read the docs, I think I found an oh-so-ugly
solution:

layout proc{ |controller| [ ‘new’, ‘etc’
].include?(controller.action_name) ? ‘application’ : ‘otherlayout’ }

Thanks

Try this instead: specify a default controller-wide layout, and then
action-specific layouts defined within the action itself via render.

class MyController < ActionController::Base
layout “default_layout”

def foo
  render :action => "foo", :layout => "foo_layout"
end

end
