i'm subclassing ForeignKey but can't figure out howto access actual instance (model data). if i'm doing "class MyField(ForeignKey)", what do i need to override, which MyField method, where i have access to related instance data (or None if it doesn't exists)?
digging through the code i've found "self.rel" and "self.related" but didn't figure out how to get actual model instance or related model instance. i've read https://docs.djangoproject.com/en/1.3/howto/custom-model-fields/ and similar docs, tried searching through the source code but the best thing i've found was id or similar. is this some kind design decision or am i just missing something obvious? what i'm actually trying to create is a custom widget (would call it advanced compared to basic widgets available in django forms/admin) but i need model instance data in widget. i've heard theories while asking about this that it's not necessary to have model instance to create a custom widget but i've found it impossible to create a generic reusable widget which interacts with the entire form and available form data (client and server side) and also with external services (rest/soap api) without access to model instance. any tips, links, docs or any constructive comments are appreciated.
