python - Django rest framework, do serializer require fields to be specified?

Question

Let's say we have model:

class CompanySource(models.Model):
    company = models.ForeignKey(Company, on_delete=models.CASCADE, related_name='company_source')
    source = models.CharField(max_length=1500)

and we want to have seralizer for it and we use HyperlinkedModelSerializer it looks like this

class CompanySourceSerializer(serializers.HyperlinkedModelSerializer):
    def create(self, validated_data):
        return CompanySource.objects.create(**validated_data)

    class Meta:
        model = CompanySource
        fields = ['id', 'company', 'source']

is it required to set source = serializers.CharField(max_length=1500) inside Serliazer and what does it contribute to? Thank you

Answer 1

It is not important.

Rest framework serializers are designed to take the hassle out of your hands.

Refer to here.

And for your case, why not use Model serializer?. You do not seem to be needing links
