'Command' object has no attribute 'stdout'

Question

from django.core.management.base import BaseCommand, CommandError
class Command(BaseCommand):
    def handle(self, *args, **options):
        ......
        self.handle_noargs()

    def handle_noargs(self, **options):
        packages_count = Package.objects.all().count()
        Package.objects.all().delete()
        print >> self.stdout, u'Deleted %d packages' % packages_count
        ......

I am writing tests for provided code, but whenever I call handle_noargs function I receive following error :

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

I am using Django 1.3.1.

>>> import django
>>> django.VERSION
(1, 3, 1, 'final', 0)

Regarding googling answer stdout was implemented in BaseCommand class some versions ago so I have no idea why django cant find it.

Adding dir(self):

>>> from webui.packagedb.management.commands.packagedb_clear import Command
>>> dir(Command)
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribut
e__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_e
x__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '_
_weakref__', 'args', 'can_import_settings', 'create_parser', 'execute', 'get_ver
sion', 'handle', 'handle_noargs', 'help', 'option_list', 'output_transaction', '
print_help', 'requires_model_validation', 'run_from_argv', 'usage', 'validate']

Don't know anything about Django, but is that meant to be self.stdout or sys.stdout? — NPE

i think you can not call handle_noargs directly, the BaseCommand class command has an execute() method which calls handle() and before initializes stdout and stderr

so every time you run a command, the execute() method is called which expects the handle method to be implemented

I dont call it directly, I call it trough handle() when handle has no arguments. Same in tests.

you shouldnt call handle either, since all the initialization stuff is done in execute(), and without that your command may not produce the expected results
