Re: how to get all objects related to a particular user using django ContentType Framework

So, you have a custom model like following

class MyModel(models.Model):
...
content_type = models.ForeignKey(ContentType)
...

And you want to run a query on MyModel which should return objects
from various apps related to currently logged in User.

Is this what you want to achieve?
