Instead of Primary Key Send Different Field in Django REST Framework

Question

serializers.py

class MovieSerializer(serializers.ModelSerializer):

    class Meta:
        model = Movie
        fields = [
            \'popular         


        

Answer 1

The easy solution would be to change the Genre model to use name as primary key, like so:

class Genre(models.Model):
    name = models.CharField(max_length=30, primary_key=True)

Not that it matters much here, but this will also save a column in the database, since the auto generated id column will disappear :)

Update

After some discussion in the comments to this answer, I find it important to mentions that using ANY type as primary key, you should also avoid changing that field afterwards.

This is because a change to the primary key, also necessitates an update to all the foreign keys pointing to that primary key, and (to put it in terms of this question) even though your table with genres may be relatively small, you may have a significant amount of movies pointing to each genre.
