django admin custom commands - passing a list of strings into args

Question

I have a list of strings which I would like to pass into args in my django custom command.

list = ['abc', 'def', 'ghi', etc...]

How can I do this from within a python function:

management.call_command('commandname', args, options)

I've tired passing on my list of args both:

[1] directly:

    management.call_command('commandname', list)

and

[2] as a loop:

    management.call_command('commandname', (abc for abc in list))

but both have failed after entering the custom command

The call_command method is using Arbitrary Arguments List for command arguments.

So, you need to use:

list = ['abc', 'def', 'ghi']
management.call_command('commandname', *list)

Which is the same than:

management.call_command('commandname', 'abc', 'def', 'ghi')

Can you give a example using what I've specified above? Sorry this just isn't very helpful without an example.

Just call it like this: management.call_command('commandname', 'abc', 'def', 'ghi')

Is there a max number of args for a django command? I have a list of 500 args and it's crashing at the end. A test with 10 args worked perfectly.

@thong i just tried to pass 10^7 *args and 10^7 *kwargs to a normal python function and it still worked. not sure about django functions peculiarities though.
