@dianakhuang @brianhw review please.

Because make_option was missing, django-admin was getting confused by the --courses argument.

I tried to write a test for it (using call_command) but it skips the django-admin parser. Other alternatives are a too elaborate.

I'll check with you tomorrow to understand the django-admin problem. Did this ever work?

[rocha]

@brianhw the make_option is required by the parser used in django-admin.py. The tests pass correctly, since they call the command without having to parse the arguments.

@dianakhuang @brianhw review please.

I thought we had merged this already. It is required to run the EmailOptInTask in the data exporter.

My apologies -- I also thought this was merged long ago. I'm assuming the test failure is unrelated. LGTM. 👍

[rocha]

@brianhw thanks. Yeah, the test error is from a flaky bok choy test.
