How do I create indexes in Django migrations?

You can create indexes in Django migrations by using the indexes option in your model's Meta class.

Can you show me an example of how to do that?

Sure! Here's an example:

class MyModel(models.Model):
    name = models.CharField(max_length=100)

    class Meta:
        indexes = [
            models.Index(fields=['name']),
        ]

What if I want to create a unique index?

You can create a unique index by using the UniqueConstraint in the Meta class like this:

class MyModel(models.Model):
    name = models.CharField(max_length=100)

    class Meta:
        constraints = [
            models.UniqueConstraint(fields=['name'], name='unique_name'),
        ]

Do I need to run any commands after modifying the migration?

Yes, after modifying your migration, you should run python manage.py makemigrations and then python manage.py migrate to apply the changes.
