Hi all!!
Recently , i tryed to integrate flex and rail, and it was a nice work,
really fast and flexible, until a curious bug
On my local development machine, i try to destroy an item trough an id,
and all goes well.
i set up on the production machine and pop-up this error:
NoMethodError (undefined method `[]'' for nil:NilClass)
here''s the code of the mxml in question:
<mx:HTTPService contentType="application/xml"
id="destroy_question"
url="http://localhost:3000/admin/questions/destroy_question_xml"
useProxy="false" method="POST"
result="object_destroyed()"
fault="object_not_destroyed()" >
<mx:request xmlns="">
<question>
<id>{qdg.selectedItem.id}</id>
</question>
</mx:request>
</mx:HTTPService>
and here''s the controller:
def destroy_question_xml
if params[:question][:id][:value]
@question = Question.find(params[:question][:id][:value])
@question.destroy
@question.save
end
end
The curious thing is that actually, on production machine, it send
correctly the
values("question"=>{"id"=>{"type"=>"integer",
"value"=>"96"}}) , but still pop up the error
NoMethodError (undefined
method `[]'' for nil:NilClass).
Someone has some thougt on this?
thanks a lot for reading

For example, def destroy_question_xml if params[:question][:id][:value] @question = Question.find(params[:question][:id][:value]) @question.destroy @question.save end end Thus, I would recommend checking your logic.

i don''t know about your system, but maybe you try to do something over ssl and you don''t have it configured for your webserver? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

It means you have a filter called require_ssl in your application. This kind of filter will usuallly either redirect or stop the current request if it is not made over ssl (e.g https://example.com) find the one in your app to see more. Either make the web request over ssl, or skip the filter if you don''t need to use ssl. I''d recommend to use ssl if this is a request that is being authenticated in some way.
