I am using the standard Admin Panel in Django that has a Model, Product, that contains its information. the Product has a TextField() Summary of words.

I would like to implement a Keyword model that has a single word. The idea is that the Keyword would be applied to multiple Products if the Product has the Keyword's word in its Summary.

I am trying to implement that when the Admin in the Admin panel adds a Keyword model, the server would automatically assign each Product that Keyword.

The issue is that I do not know how to edit the Admin Panel's add function to edit other models upon adding one model. My current understanding in Django is that you could create a custom view to add a Keyword, but I would like to have the option to implement it in the Django Admin Panel as well. Products should have multiple Keywords.

Here is my models.py:

    from django.db import models

    class Product(models.Model):
        id = models.BigAutoField(primary_key=True)
        product_summary = models.TextField() # Contains a paragraph of words describing the product
    class Keyword(models.Model):
        # Used for searching Products by unique keywords to display, like tags.
        keyword = models.CharField(max_length=100)
