ChoiceField

Just write verbose text like this in your models.

class Product(models.Model):

    CATEGORY = [
        ('F', 'Food'),
        ('L', 'Living Item'),
    ]

    category = models.CharField(
        verbose_name='Category',
        max_length=1,
        choices=CATEGORY,
    )

And ModelSerializer might set this field as ChoiceField, and this package write down enum k-v list on your documentation automatically.

Others

Write example value in your serializer class like this.

class ProductSerializer(serializers.ModelSerializer):

    class Meta:
        model = Product
        fields = '__all__'
        example = {
            'name': 'Apple',
            'amount': 6,
            'price': '10.00',
        }

Then drf-yasg will add example on your docs automatically.
