error :object can't be deleted because its id attribute is set to None

Question

Trying to Delete an object using shell in django. How do i delete the object say "Ron"?

I use the following command:

t.delete('Ron')

Answer 1

The error:

object can't be deleted because its id attribute is set to None

Suggests that you either never saved the object t in the first place, or you changed the primary key (here id) to None manually.

If you have a single object you can perform a .delete() on the object, for example:

my_obj = Model.objects.get(name='Ron')
my_obj.delete()

You should not add extra parameters to delete except for using and keep_parents, as specified in the documentation for Model.delete()

Or you can delete the objects with a .filter(..) statement, like:

Model.objects.filter(name='Ron').delete()

this will delete all Model objects with name 'Ron'.
