django prepopulated_fields

The prepopulated_fields feature in Django allows you to automatically populate certain fields in a model based on the values of other fields. Here are the steps to use prepopulated_fields:

1. First, define the prepopulated_fields dictionary in your model admin class. This dictionary should contain the field names you want to prepopulate and the fields that will provide the values.

2. In your model admin class, define a prepopulated_fields dictionary. The keys of this dictionary should be the field names you want to prepopulate, and the values should be a list of fields that will provide the values for prepopulating.

3. In the model admin class, add the prepopulated_fields attribute and set it to your prepopulated_fields dictionary.

4. Optionally, you can specify a prepopulated_fields attribute on a specific field in your model. This attribute should be a dictionary with the prepopulate_from key, which contains a list of fields to use for prepopulating.

5. To use the prepopulated_fields feature, simply include the desired fields in the fields attribute of your model admin class.

That's it! Django will now automatically populate the specified fields based on the values of the fields you have defined. This can save you time and effort when creating or updating model instances through the Django admin interface.
