django : How to write alias in queryset

Question

How can one write an alias for the column name in django query set. Would be useful for union-style combinations of two linked field to the same foreign model (for instance).

Answer 1

Your reason in the comment makes no sense. Each field in the model has its own column in the database, and there's never any danger of mixing them up. You can of course tell a field to use a column name that's different from the field name:

myfield = models.CharField(max_length=10, db_column='differentname')

but I don't know if that will help you, because I still don't know what your problem is.
