I have defined my function like this:

    @api.multi
    def name_get(self):
        retvals = []     
        for record in self:
            if context.get('prod_form', False):
                catstring =  "[" + record.name + "] " + record.description
                retvals.append((record.id,catstring))
            else:
                retvals.append((record.id,record.name))
       
        return retvals

I've tried to use "context" by itself, as "self.context", "context.get()", etc.  I get errors all around.  How do I test to see if a context is set, if I use "self" as the only parameter?  Can I just say "def name_get(self, context=None)" ?
