[Facebooker-talk] alias_method_chain in Facebooker Causing Stack Level Too Deep
I installed the Facebooker plugin and upon placing it on a staging server, I
keep running into stack level too deep errors. It seems to stem from
Facebooker using alias_method_chain to override some of the
ActionController methods. I believe it''s getting loaded twice causing
confusion. I''ve tried various methods include wrapping a unless
respond_to?(:method) around the alias_method_chain call to keep it
from being called twice. However, none of this has worked? Has anyone run
into this problem and found a remedy? I know alias_method_chain is a pretty
popular way to override methods, so I
can''t imagine this being the first instance of alias_method_chain
causing
this problem. Here is some of the sample code I''m looking to fix:
module ::ActionController
class Base
def self.inherited_with_facebooker(subclass)
inherited_without_facebooker(subclass)
if subclass.to_s == "ApplicationController"
subclass.send(:include,Facebooker::Rails::Controller)
subclass.helper Facebooker::Rails::Helpers
end
end
class << self
unless ActionController::Base.respond_to?
(:inherited_with_facebooker)
alias_method_chain :inherited, :facebooker
end
end
end
end
Here you can see the method inherited has been aliased to
inherited_with_facebooker and inherited_without_facebooker has been aliased
to inherited. However, when the method is called
inherited_without_facebooker goes into an endless recursive call which
results in a stack level too deep error. I tried to prevent
alias_method_chain from being called twice (which is what I suspect the
problem being) by checking if inherited_with_facebooker already exists. It
has not seemed to fix the problem. Does anyone else have a possible
solution I may try. Thanks again!
