I am trying to use call_command
to download data from a URL and was wondering on how to call it from the code.
I have declared the option lists as follows in my code:
option_list = BaseCommand.option_list + (
make_option('--url', default=None, dest='url', help=_(u'Specifies the full url of the json data to download.')),
make_option('--username', default=None, dest='username', help=_(u'Login of the person doing the download.')),
make_option('--password', default=None, dest='password', help=_(u'Password of the person doing the download.')),
make_option('--file', default=None, dest='file', help=_(u'File name of the json data to download in gzip-compressed-data format')),
)
I use it as follows from the command line:
./manage.py download --url=http://some-link.com/download/ --username=admin --password=admin
So far I have the following:
call_command('download')
How do I pass in the rest of the parameters/args?
Just pass them as keyword arguments:
call_command('download',
url="http://some-link.com/download/",
username="admin",
password="admin")
The keyword arguments should reflect the dest
values of your custom management command arguments.
Example for flush
command:
--initial-data
command-line argument in call_command()
can be set by passing load_initial_data
keyword argument:
call_command('flush', load_initial_data=False)
This is because it is --initial-data
's argument destination:
parser.add_argument('--no-initial-data', action='store_false',
dest='load_initial_data', default=True,
help='Tells Django not to load any initial data after database synchronization.')
