How to set the admin user ID as a foreign key in Django another table

To set the admin user ID as a foreign key in another table, you can use Django's built-in User model from the django.contrib.auth.models module. Here's an example:

1. Open the file containing the model where you want to set the foreign key, typically models.py in your app directory.

2. Import the necessary modules:

from django.contrib.auth.models import User
from django.db import models

3. Define your model and set the foreign key relationship with the User model:

class YourModel(models.Model):
    admin_user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
# Other fields of your model

In the above code, the admin_user field is defined as a foreign key to the User model. The on_delete parameter specifies the behavior when the referenced user is deleted. In this case, models.SET_NULL is used to set the admin_user field to NULL if the referenced user is deleted. You can adjust this behavior according to your requirements.

4. Generate and apply the necessary database migrations to create the foreign key relationship. Run the following commands:

python manage.py makemigrations
python manage.py migrate

These commands will create the migration files and apply the changes to the database.

Now, you can access the admin user associated with a record in the other table through the admin_user foreign key field.

Note: If you're using a custom user model instead of Django's default User model, make sure to update the import statement and reference your custom user model in the foreign key field definition.
