What are some examples of Django ORM migrations?

Can you explain what Django ORM migrations are?

Django ORM migrations are a way to manage changes to your database schema over time. They allow you to create, modify, and delete database tables and fields in a structured manner.

What does a typical migration file look like?

A typical migration file in Django includes a class that inherits from migrations.Migration, and it defines operations like AddField, RemoveField, or AlterField.

Can you give me an example of a migration that adds a new field?

Sure! Here's an example:

from django.db import migrations, models

class Migration(migrations.Migration):
    dependencies = [
        ('app_name', 'previous_migration'),
    ]

    operations = [
        migrations.AddField(
            model_name='model_name',
            name='new_field',
            field=models.CharField(max_length=100),
        ),
    ]

How do I apply these migrations to my database?

You can apply migrations using the command python manage.py migrate. This will apply all unapplied migrations to your database.
