Django: Querying read-only view with no primary key

Question

class dbview(models.Model):
    # field definitions omitted for brevity
    class Meta:
        db_table = \'read_only_view\'

def main(request):
    result = dbview         


        

Answer 1

I have this issue all the time. I have a view that I can't or don't want to change, but I want to have a page to display composite information (maybe in the admin section). I just override the save and raise a NotImplementedError:

    def save(self, **kwargs):
        raise NotImplementedError()

(although this is probably not needed in most cases, but it makes me feel a bit better)

I also set managed to False in the Meta class.

    class Meta:
       managed = False

Then I just pick any field and tag it as the primary key. It doesn't matter if it's really unique with you are just doing filters for displaying information on a page, etc.

Seems to work fine for me. Please commment if there are any problems with this technique that I'm overlooking.
