Launch django management commands from the admin

Django-AdminCommand

Django-AdminCommand is a Django application that makes it possible to run Django management commands from the admin.

Dependencies

• django-async
• django-sneak

Settings

You need to activate the Django admin in the settings and urls.py depending on your needs the configuration may vary, refer to the Django documentation related to the admin application.

Don't forget to add the application where you defined management commands in the list of installed applications. This might be already done but it might not be the case if you use an application to gather all the management commands that must be admin commands.

Make magic happens

Create a Django Management Command:

# ./music/management/commands/lyrics.py


class Command(BaseCommand):
    help = "Compute lyrics based an bitorological fluctuations"

    def handle(self, *args, **options):
        # algorithm that generated lyrics based on a title and a dictionary

Then you will have to create a configuration class for the command:

# ./music/admincommands.py

from admincommands.models import AdminCommand


class Lyrics(AdminCommand):

     class form(forms.Form):
         title = forms.CharField()

     def get_command_arguments(self, forms_data):
         return [forms_data['title']], {}

And all is well, the new admin command will be available under the «Admin Command» area of the administration of the default admin site.

If you use custom admin site, don't forget to register admincommand.models.AdminCommand to the admin site object.

Asynchronous tasks

If you want to execute commands asynchronously you have to specify it in the AdminCommand configuration class with the asynchronous property set to True:

# ./music/admincommands.py

from admincommands.models import AdminCommand


class Fugue(AdminCommand):

     asynchronous = True

     class form(forms.Form):
         title = forms.CharField()

     def get_command_arguments(self, forms_data):
         return [forms_data['title']], {}

You also need to run periodically flush_queue from django-async application for that matter don't forget to install the application.

Permissions

You MUST add to every user or groups that should have access to the list of commands «Can change admincommand» permission. Every admin command gets it's own permission «Can Run AnAdminCommand», so you can add it to proper users or group. Users will only see and be able to execute admin commands for which they have the permission.
