Django Database Purge

The Django Database Purge management command is a tool for efficiently removing unwanted records from your Django project's database based on a specified retention policy. This command helps you keep your database clean and optimized by permanently deleting records that are no longer needed.

Features:

• Flexible Retention Policy: Define your own retention policy to determine which records should be purged from the database.
• Efficient Data Management: Easily manage the size of your database by removing outdated or unnecessary records.
• Customizable: Adapt the command to suit your project's specific requirements and database structure.
• Safe: Built-in safeguards to prevent accidental data loss, ensuring that only the intended records are purged.

How to Use:

1. Install django-db-purge by running:

pip install django-db-purge

2. Include 'dbpurge' in your INSTALLED_APPS settings.

3. Locate the db_purge.py file in the management/commands directory of the Django dbpurge app.

4. Add your own values to the retention policies dictionary in the db_purge.py file, based on your requirements. Below is a guide on how to set up the retention policies:

   1. app_name

   • Description: Name of the Django app containing the model.
   • Example: my_django_app

   2. model_name

   • Description: Name of the Django model from which records will be deleted.
   • Example: MyModel

   3. time_based_column_name

   • Description: Name of the column in the model that contains the timestamp or datetime field used for determining the age of records.
   • Example: created_at

   4. data_retention_num_seconds

   • Description: Time duration in seconds for which records will be retained before deletion.
   • Example: 2592000 (for 30 days)

   Example:

   retention_policies = [
       {
           'app_name': 'my_django_app',
           'model_name': 'MyModel',
           'time_based_column_name': 'created_at',
           'data_retention_num_seconds': 2592000,  # 30 days in seconds
       },
       # Add more retention policies as needed
   ]

5. Then, either periodically call the db_purge management command (e.g., via a system cronjob), or install and configure django-cron.
