option does not take a value error

Question

I have this Command(BaseCommand) class with this defined:

make_option('--username', action='store_true', dest='username', default=None),

Then I try to run it like this:

python manage.py thescript --username=something

The output is:

manage.py: error: --username option does not take a value

Why?

---

EDIT

I am always getting None:

class Command(BaseCommand):
    args = '--username=username ...'
    help = '...'

    option_list = BaseCommand.option_list + (
        make_option('--username', action='store', default=None, help='...'),
    )

    def handle(self, *args, **options):
        print options['username']

Answer 1

The line store_true will cause the command to store the boolean value True if the argument --username is given, rather then storing the next value.

I suspect that doing something along the lines of action='store' would do what you expect.

I think you're currently using optparse, correct? If so, you can find a full listing of the different kinds of actions available in the optparse documentation.
