Error Outputting System Checks in django/core/management/base.py

Description

I'm trying to install celery==3.1.17 with django 1.8b2 (following the celery + django install instructions).

I get the following TypeError when I try to launch a celery worker AND have unresolved system warnings:

Trying to launch celery worker...

celery -A my_project worker -l info

yields ...

  File "/usr/local/etc/virtualenvs/gears/local/lib/python2.7/site-packages/celery/fixups/django.py", line 162, in validate_models
    cmd.check()
  File "/usr/local/etc/virtualenvs/gears/local/lib/python2.7/site-packages/django/core/management/base.py", line 530, in check
    self.stderr.write(msg, lambda x: x)
TypeError: function takes exactly 1 argument (2 given)

It appears that Django is throwing a TypeError at this line in django/core/management/base.py

The problem "goes away" if I silence Django's system checks.

Hi,

This seems more like a bug on celery's side, caused by this line: https://github.com/celery/celery/blob/master/celery/fixups/django.py#L161

Management's commands self.stderr and self.stdout should be instances of OutWrapper whose write() method support more than one argument (in this instance, a style_func argument used for formatting).

I'm going to mark this as invalid. Feel free to reopen if you think there's really something we should fix on Django's end.

Thanks.

Ah, thanks for the details, that makes a lot of sense. I'll open up a ticket with the Celery folks.

Thanks again!
