In Django, migrations are used to propagate changes you make to your models (Python classes) into the actual database schema (tables, columns, constraints, etc.).

Steps to Perform Migrations:

1. Make Migrations

Run the following command to create migration files based on the changes in your models.py:

This command analyzes your models and creates a migration file inside the migrations/ folder of your app. It describes the operations needed (like adding a field, creating a model, etc.).

2. Apply Migrations

After creating the migration files, apply them to the database with:

This applies all unapplied migration files and updates the database schema accordingly.

3. Check Migration Status (Optional)

To see which migrations have been applied:

Notes:

• You should run makemigrations every time you change a model.

• migrate should be run after makemigrations to apply the changes.

• Migration files are version-controlled and can be shared with others.

In summary, use makemigrations to create migration files and migrate to apply them to your database.
