django database specify schema

First, define your models in Django by creating a new Python class for each database table you want to include. Each class should inherit from django.db.models.Model.

Use field instances to define the type of data each field will hold. For example, use models.CharField for character fields, models.IntegerField for integer fields, and models.DateTimeField for date and time fields.

Next, use field options to specify any additional properties for each field, such as max_length for CharField, unique for unique fields, and default for default field values.

After defining your models and fields, create a migration file using the makemigrations command. This will generate a file that contains the changes that need to be applied to the database schema.

Finally, apply the migration to the database using the migrate command. This will update the database schema based on the changes defined in the migration file.

Remember to review and adjust your models and field options as needed before creating and applying migrations to ensure your database schema accurately reflects your application's requirements.
