Building the course serializer

We are going to create a serializer for the Course model. Edit the api/serializers.py file of the courses application and add the following code highlighted in bold:

# ...
from courses.models import Course, Subject
class CourseSerializer(serializers.ModelSerializer):
    class Meta:
        model = Course
        fields = [
            'id',
            'subject',
            'title',
            'slug',
            'overview',
            'created',
            'owner',
            'modules'
        ]

Let’s take a look at how a Course object is serialized. Open the shell and execute the following command:

python manage.py shell

Run the following code:

>>> from rest_framework.renderers import JSONRenderer
>>> from courses.models import Course
>>> from courses.api.serializers import CourseSerializer
>>> course...
