✅

you can use SerializerMethodField:
https://www.django-rest-framework.org/api-guide/fields/#serializermethodfield

class FarmerSerializer(serializers.ModelSerializer):

    class Meta:
        model = Farmer
        fields = [
            'id', 'username', 'cpf', 
            'email', 'age', 'phone', 
            'sex', 'active', 'password', 'property'
        ]
        extra_kargs = {
            'cpf': {'write_only': True},
            'active': {'read_only': True}
        }
        property = serializers.SerializerMethodField()


        def get_farmers_property(self, farmer_obj):
            all_farmers_property = Property.ojbects.filter(farmer = farmer_obj)
            return all_farmers_property

‘Farmer’ object has no attribute ‘property’, because it has ‘property_farmer’ 🙂

in your property model you should:

 farmer = models.ForeignKey(
        Farmer,
        related_name='property',
        on_delete=models.DO_NOTHING
    )

Change related_name to ‘property’ so you can access property as farmer.property and not farmer.property_farmer.
