Comment:
Thanks for the report.
In Django 1.11 your custom command raises `TypeError: __init__() missing 1
required positional argument: 'cmd'` which has been fixed in
dd68b51e1da54267bde4799fa0d9fbd4290eb8b5. I wasn't able to run your
example in Django < 2.2.
`call_command('mycommand', 'foo', bar=True)` raises `TypeError: Unknown
option(s) for mycommand command: bar.` which seems fine for me because you
added only `--bar` argument, i.e.
{{{
>>> management.call_command('mycommand', 'foo', '--bar', '1')
>>> management.call_command('mycommand', 'foo', '--bar', True)
}}}
work as expected.
IMO there is only issue with validation of `call_command('mycommand',
subcommand='foo', bar=True)` because it raises
{{{
File "django/core/management/__init__.py", line 130, in <listcomp>
for opt in parser._actions if opt.required and opt.dest in options
ValueError: min() arg is an empty sequence
}}}
