What are some examples of using hooks in Django?

In Django, hooks are often used in signals and middleware. For example, you can use the pre_save signal to perform actions before saving a model instance.

Can you give me a specific code example of a pre_save hook?

Sure! Here's a simple example:

from django.db.models.signals import pre_save
from django.dispatch import receiver
from .models import MyModel

@receiver(pre_save, sender=MyModel)
def my_model_pre_save(sender, instance, **kwargs):
    instance.name = instance.name.upper()  # Convert name to uppercase before saving

What about using hooks in Django REST Framework?

In Django REST Framework, you can use hooks in serializers. For instance, you can override the create method to customize object creation.

Can you show me an example of that?

Absolutely! Here's an example:

class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

    def create(self, validated_data):
        # Custom logic before creating the object
        return super().create(validated_data)
