AttributeError: 'Command' object has no attribute 'style'

[Stefan Kögl]

When testing #19665 (currently at c87f89c0db9314d26a3ad9afceb812e2d2f07f96) another (possibly related) exception was raised when executing the command

$ ./manage.py assign-upload-timestamps
/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py:219: DeprecationWarning: You have no filters defined on the 'mail_admins' logging handler: adding implicit debug-false-only filter. See http://docs.djangoproject.com/en/dev/releases/1.4/#request-exceptions-are-now-always-logged
  DeprecationWarning)

Traceback (most recent call last):
  File "./manage.py", line 36, in <module>
    execute_manager(settings)
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 469, in execute_manager

    stderr = getattr(self, 'stderr', OutputWrapper(sys.stderr, self.style.ERROR))
AttributeError: 'Command' object has no attribute 'style'

Again, as no part of the trace refers to code of my application, I assume a bug in Django 1.5.

The same command does not raise any exceptions with Django 1.4.

Is it possible that you overrided BaseCommand.__init__ but forgot to ​call super?

[Simon Charette]

Are you even subclassing BaseCommand?

[Claude Paroz]

We definitely need more information about your code.

Replying to charettes:

Yes, exactly that was the problem.
