using argparse with runscript?

Is there a way to use argparse in combination with runscript? The only way I have found to pass arguments to my script from the command line is to do something like this:

python manage.py runscript myscript --script-args="1,a,banana"

Which is a little cryptic. What I’d like to be able to do is say:

python manage.py runscript myscript --number=1 --letter=a --fruit=banana

If I try to wrap up my args in quotes, like so:

python manage.py runscript myscript --script-args="--number=1 --letter=a --fruit=banana"

I get messages about “unknown parameter ‘number’”, which leads me to think that that’s being raised by the runscript command.

Any hints appreciated, or if there’s a good idea about how to implement this, I’d give it a try.

I have not looked at this in a long time. IIRC, the underlying issue was that the “unrecognized arguments” error is raised by Django code, not by the django-extensions code. FWIW, I have started doing things this way:

def do_real_work(foo, bar):
    print foo, bar

def run(*args):
    """
    usage:  python manage.py runscript myscript --script-args="--foo=XXX --bar=YYYY"

    example:  python manage.py runscript myscript --script-args="--foo=something --bar=3"
    """
    import shlex
    import argparse

    parser = argparse.ArgumentParser()
    parser.add_argument("--foo", required=True)
    parser.add_argument("--bar", required=True)

    try:
        split_args = shlex.split(args[0])
    except IndexError:
        split_args = []

    args2 = parser.parse_args(split_args)

and then my invocation looks like

python manage.py runscript myscript --traceback --script_args="--foo=something --bar=3"
