DecimalField receiving django.contrib.gis.db.models.query.GeoQuerySet

[paulocheque]

Libs:

django==1.8.2
djangorestframework==3.1.3
djangorestframework-gis==0.9.1

settings:

'COERCE_DECIMAL_TO_STRING': True

Model:

class A(models.Model):
    aaa = models.PolygonField(null=True, blank=True, srid=4326)

Serializer:

class Aserial(GeoModelSerializer):
    class Meta:
        model = A
        fields = ('aaa',)

And serializer.data returns:

  File "/Users/paulocheque/Programming/leaf-toptal/Leaf-Management-Software/env1.8/lib/python3.4/site-packages/rest_framework/serializers.py", line 622, in data
    ret = super(ListSerializer, self).data
  File "/Users/paulocheque/Programming/leaf-toptal/Leaf-Management-Software/env1.8/lib/python3.4/site-packages/rest_framework/serializers.py", line 217, in data
    self._data = self.to_representation(self.instance)
  File "/Users/paulocheque/Programming/leaf-toptal/Leaf-Management-Software/env1.8/lib/python3.4/site-packages/rest_framework/serializers.py", line 572, in to_representation
    self.child.to_representation(item) for item in iterable
  File "/Users/paulocheque/Programming/leaf-toptal/Leaf-Management-Software/env1.8/lib/python3.4/site-packages/rest_framework/serializers.py", line 572, in <listcomp>
    self.child.to_representation(item) for item in iterable
  File "/Users/paulocheque/Programming/leaf-toptal/Leaf-Management-Software/env1.8/lib/python3.4/site-packages/rest_framework/serializers.py", line 439, in to_representation
    ret[field.field_name] = field.to_representation(attribute)
  File "/Users/paulocheque/Programming/leaf-toptal/Leaf-Management-Software/env1.8/lib/python3.4/site-packages/rest_framework/serializers.py", line 439, in to_representation
    ret[field.field_name] = field.to_representation(attribute)
  File "/Users/paulocheque/Programming/leaf-toptal/Leaf-Management-Software/env1.8/lib/python3.4/site-packages/rest_framework/fields.py", line 863, in to_representation
    value = decimal.Decimal(six.text_type(value).strip())
decimal.InvalidOperation: [<class 'decimal.ConversionSyntax'>]

I printed the value and its type and the GeometryField(allow_null=True, required=False) is receiving a django.contrib.gis.db.models.query.GeoQuerySet

I am upgrading DRF from 2 to 3. I think I missed some many=True. Anyway, if it was possible to send a better exception it would be great.

Hi @paulocheque, sorry I need a bit more context to understand your issue and determine if it's something that can be improved in drf-gis or not.

[paulocheque]

It is a bad exception message in DRF. Sorry about the issue.
