Parsing Route Parameters

[iamMHZ]

Suppose we have this urlpattern /<int:school_id>/courses and we wanna access school in the serializer ( I know that we can do self.context['view'].kwargs['school_id'])

But would it be possible to have it as a serializer field?
Something like this:

class CourseSerializer(serializers.Serializer):
    school = serializers.RouteParameter(name='school_id', queryset=School.objects.all())
    ....
