Determining Action in the Controller

Rails
1

Hi,

I am trying to select a layout for a page based on what action is
called.
ex.

if controller.action_name == ‘about’
layout “internal”
else
layout “home_static”
end

But I am receiving this error:

undefined local variable or method `controller’ for HomeController:Class

Is there any way that I can do this? Is this even possible?

Thanks,

Jonathon

Hmm, not sure if this will work, but since the controller is the
object and the “actions” are just methods then:

if self.respond_to?(about)
layout “internal”
else
layout “home_static”
end

I’m not sure whether layout can be called conditionally this way, but
I am sure that “controller” is an instance variable, not a local
variable. Try something like:

if @controller.action_name == 'about'
  layout "internal"
else
  layout "home_static"
end

Found out the answer.

layout :choose_layout

private
def choose_layout
if [ ‘signup’, ‘login’ ].include? action_name
‘login’
else
‘admin’
end
end

This works perfectly.

Hmm, interesting question, you could look at how Radiant or Typo or
other apps do themes, e.g.
