It looks like you want to, basically, store a reference to a Python object
in your Model. It shouldn't be too extremely difficult. I'd create a Model
for this purpose though and just use extra methods to provide any
functionality you need. Just as a quick prototypical example:
class ReferenceModel(Model):
_reference = models.CharField(max_length=150)
def get_reference(self):
"""
Load the string from self._reference and use some sort of a process
to dynamically load the object.
e.g.
http://stackoverflow.com/questions/547829/how-to-dynamically-load-a-python-class
"""
def set_reference(self, input):
self._reference = input
foo = property(get_reference, set_reference)
Anyways, just a guess at one of many ways to possibly accomplish this task.
