#10080 closed Bug (fixed)

call_command doesn't take into account command's default options

When I want to use command from python I must specify all options on which this command is depend.

Almost everyone custom command's author write execute method something like this:

class Command(BaseCommand):
    option_list = [make_option("--some_option", default="foobar")]

    def execute(self, *args, **options):
        some_option = options["some_option"]

And when I call it using call_command without some_option is specified I get the KeyError. But it works fine in command line because optparse provides default values.

>>> call_command("some_command")
Traceback (most recent call last):
KeyError: 'some_option'

Patch solves this inconsistence.

(In [10401]) [1.0.X] Fixed #10080: call_command now takes option defaults into account, sparing individual commands from any difference between call_command and being run from the shell. Thanks, Alex Koshelev. Backport of 10400 from trunk.

The patch solves the problem if the option has a default value, it still doesn't work if no default value is specified. In those cases, optparse sets the options value to None but call_command plainly excludes it which leads to problems with some commands. This update makes it work for me:

    defaults = {}
    for o in klass.option_list:
        v = o.default
        if v is NO_DEFAULT:
            v = None
        defaults[o.dest] = v
