class User::Signin::BaseController \< User::BaseController

before\_filter :before\_filter\_setup\_user  
def before\_filter\_setup\_user  
puts “hi”  
end

def index  
end

end

class User::Signin::BasicController \< User::Signin::BaseController

def index  
end

end

The filter gets called twice, “hi” prints twice, what is the best way  
to prevent this?
