Array shows position ID instead of string value

[kruppy]

Hi,

I have 2 models, Job and Topic:

class Job(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4(), editable=False)
    job_title = models.CharField(max_length=255)
    topic = models.ManyToManyField(to=Topic, blank=True)
 

class Topic(models.Model):
    name = models.CharField(max_length=255)

When trying to expose it as an API via DRF, I get following JSON:

[
    {
        "id": "fdca2bd2-b3b0-453b-a1a3-a52ca061e665",
        "job_title": "Build MVP",
        "topic": [
            1, 
            2,

        ],
        
    }
]

But I want "topic" to contain the String-values instead of "1", "2".

Do I have to do something in serializer? The jobs_serializer.py looks like that:

class JobSerializer(serializers.ModelSerializer):

    class Meta:
        model = Job
        fields = '__all__'

Thanks in advance!

The SlugRelatedField and StringRelatedField examples in the docs are both close to what you're looking for.

• SlugRelatedField can support a read-write field although you'd need name to be a unique model field if that's what you need, eg... name = models.CharField(max_length=255, unique=True)
• StringRelatedField is read-only, and would need you to define a __str__ method on the Topic model.
