django-commands-ui 0.0.4

Plugin interface to list and execute existing management commands.

Django Commands UI

This project offers a solution to list and execute all existing management commands in your Django project.

Requirements

This project requires Python 3.10 or greater.

Configuration

To install and configure it these steps should be followed:

1. Install the dependency from PyPi.

   pip install django-commands-ui
   

2. Add commands_ui as an installed app in your Django project.

3. If you haven't already done so, you will need to add celery to your django project. You can follow the steps in the First steps with Django guide if you haven't used celery before.

4. Add the root location of your management commands to your installed apps. For example, if your management commands are in the commands folder in your project root, you would add your-project-name.commands to your installed apps.

5. Add these required settings:

    # Celery app name.
    COMMANDS_UI_CELERY_APP = ""
   
    # Working celery queue name for delayed jobs.
    COMMANDS_UI_DELAYED_JOBS_QUEUE = ""
   
    # Working celery queue name for standard jobs.
    COMMANDS_UI_JOBS_QUEUE = ""
   
    # Tuple of compiled regexes to extract the runnable commands from.
    # By default, all commands from all installed apps are extracted.
    COMMANDS_UI_JOB_APPS = (re.compile(r".*"),)
   
    # Primary database identifyer, not the replica one.
    DATABASE_PRIMARY = getattr(settings, "DATABASE_PRIMARY", "default")
   
    # Define if the current environment is a cron environment.
    CRON_ENVIRONMENT = getattr(settings, "CRON_ENVIRONMENT", False)
   

6. Include package URLs to your base urls file like this:

   path("jobs/", include("commands_ui.urls")),
   

7. Create tables:

   python manage.py migrate commands_ui
   

It is recommended to override base.html so the appearance is customizable, as all django-commands-ui templates extend from it.

Implementing a management command job

The only needed thing for implementing a working management command job in django-commands-ui is extending the existing JobBasedCommand. This class adds some default arguments (such as --job-id).

Example on how to use this class:

from typing import Any
from commands_ui import management_commands
from django.core.management.base import CommandParser

# Extend the JobBasedCommand class
class Command(management_commands.JobBasedCommand):
   def handle(self, *args: Any, **options: Any) -> None:
      # Any time `self.print` is used, the message will be added to both standard output and
      # Job output.
      self.print("Starting")
      for i in range(0, 20):
         self.print(i)
      self.print("Finishing")

Command Grouping

You can group types of commands by adding a interface_name class attribute to your management command class. This will group all commands with the same interface_name together in the UI. For example you can group cronjobs together by adding interface_name = "cron" to all your cronjobs.

from typing import Any
from commands_ui import management_commands
from django.core.management.base import CommandParser

# Extend the JobBasedCommand class
class Command(management_commands.JobBasedCommand):
    interface_name = "cron"
   def handle(self, *args: Any, **options: Any) -> None:
      ...
