I apologize if this the incorrect mailing list, as it is a Rails question,=
=20
not really a Ruby question. Anyway:

To apply a layout to a controller, you can say:

class UsersController < ApplicationController
layout "master"
end

...which you would need to do in every controller. So my first thought is t=
o=20
push this down into ApplicationController, mitigating the need to put=20
anything layout related in all the other controllers:

class ApplicationController < ActionController::Base
layout "master"
end

...which doesn't work. So my next thought is to declare an instance variabl=
e=20
in the ApplicationController:

class ApplicationController < ActionController::Base
@layout =3D "master"
end

and change all other controllers to look like this:

class UsersController < ApplicationController
layout @layout
end

...which doesn't work either. So I grudgingly try a global with the same=20
thought process:

class ApplicationController < ActionController::Base
$layout =3D "master"
end

class UsersController < ApplicationController
layout $layout
end

...which works. But I don't understand why, if UsersController derives from=
=20
ApplicationController, the other two methodologies fail. Can someone explai=
n=20
this to me?=20

Centralizing the layout moniker to one place will help significantly as I=
=20
move my app from test/dev/prod, so I can have alarmingly different layouts=
=20
for test/dev versus production.

putting layout in ApplicationController always works for me...

perhaps you have an odd typo or something somewhere?

Thanks for the lead, Sean. I'd used the generate scaffold to create the=20
usuals, and it created users.rhtml. When this file exists, it seems to=20
ignore the layout method in my ApplicationController, as I'm guessing the=
=20
users.rhtml is more specific / overrides that value.

Deleting the users.rhtml file resulted in the expected behavior. Thanks=20
again!
