Hi!
I am calling a method like this:
def index()
json = super.get_customers()
respond_to do |format|
format.json { render :json => json and return }
end
end
But the problem is that the underlying method get_customers might have
called a render :text => ''Invalide Parameters or whatever''
earlier and
the later code under the respond_to gives double render error. Is
there any way to discard the results of the previous rendering and
start at a clean slate?
Regards,
Moshin

Ruby doesn''t let you call super with a message name other than the current one. -- Rick DeNatale My blog on Ruby http://talklikeaduck.denhaven2.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
