django set default value for model not form

To set a default value for a field in a Django model, you can use the default attribute when defining the field. Here are the steps to do it:

Step 1: Define the field in the model In your Django model, define the field for which you want to set a default value. For example, if you want to set a default value for a field named my_field, you would define it like this:

my_field = models.CharField(max_length=100, default='default_value')

Here, CharField is just an example; you can use any field type that suits your needs.

Step 2: Migrate the changes After defining the field with the default value, you need to create a migration file and apply it to the database. Run the following command to create the migration file:

python manage.py makemigrations

This command will generate a migration file that contains the necessary instructions to modify the database schema.

Then, apply the migration by running the following command:

python manage.py migrate

This command will execute the migration and update the database with the default value for the field.

Step 3: Use the default value Once the default value is set, you can use it in your code. When a new instance of the model is created and the my_field field is not provided, it will automatically be populated with the default value specified in the model definition.

That's it! Now your Django model will have a default value for the specified field.
