How to use context in function defined with "self" as sole parameter?

I have defined my function like this:

    def name_get(self):
        retvals = []     
        for record in self:
            if context.get('prod_form', False):
                catstring =  "[" + record.name + "] " + record.description
        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)" ?

Hello Jeff, good question.

As the new API guidelines state, 'cr', 'uid' and 'context' are encapsulated in the new 'Environment' object.

Property attributes are available in the 'Environment' object for 'user' ('self.env.user') and 'lang' ('self.env.lang').

Context values can be retrieved directly as 'self.env.context.get('value_key', value_if_undefined)',  sample usage at 'res.partner'


Thanks, Marvin! I had read over that part, but it didn't register in my brain. Your example of 'self.env.context.get()' made it click. :)
