Thanks Yehuda, I tried it with self.layout=false but apparently the
layout method does not exist:
"undefined local variable or method `layout=' for #<Notes:0x1c98360> -
(NameError)"
Is there something wrong with my syntax?
Here's the controller code:
(I'm hoping to replace the commented 'request.ajax' conditions with
one 'before' filter but the before filter causes the 'undefined' error
on any action call)
class Notes < Application
before Proc.new{ self.layout = false if request.ajax? }
def index
@notes = Note.all
display @notes #, request.ajax? ? { :layout=>false } : nil
end
def edit(id)
only_provides :html
@note = Note.get(id)
raise NotFound unless @note
display @note #, request.ajax? ? { :layout=>false } : nil
end
...etc...
end
George
