set(objs, bulk=True, clear=False) New in Django 1.9. Replace the set of related objects: >>> new_list = [obj1, obj2, obj3] >>> e.related_set.set(new_list) This method accepts a clear argument to control how to perform the operation.

If clear=True, the clear() method is called instead and the whole set is added at once. The bulk argument is passed on t

Field.default The default value for the field. This can be a value or a callable object. If callable it will be called every time a new object is created.

Instead, wrap the desired default in a callable. For example, if you want to specify a default dict for JSONField, use a function: def contact_default():

BaseCommand.execute(*args, **options) [source] Tries to execute this command, performing system checks if needed (as controlled by the requires_system_checks attribute). If the command raises a CommandError, it’s intercepted and printed to stderr. Calling a management command in your code execute() should not be called directly from your code to execute a command. Use call_command() instead.
