How can I prevent data exposure in my Django APIs?

To prevent data exposure, you should implement proper authentication and authorization, use serializers wisely, and limit data fields.

What are serializers and how do they help?

Serializers in Django REST Framework convert complex data types to native Python data types. They help control what data is exposed.

Can you give an example of limiting data fields in a serializer?

Sure! You can use the fields attribute in your serializer to specify which fields to include, like this: class MySerializer(serializers.ModelSerializer): class Meta: model = MyModel fields = ['id', 'name'].

What about using permissions?

Using permissions is crucial. You can set permissions in your views to restrict access based on user roles, ensuring only authorized users can access sensitive data.
