cannot import name ModelSerializerOptions

[Lei Du]

Hi everyone,

I'm trying to use the GeoFeatureModelSerializer for a rest API I'm writing. I'm getting this error when I hit my webpage (the full traceback is at the bottom): "cannot import name ModelSerializerOptions"

This is my serializer.py file, which I use to create my views:

```

from rest_framework import serializers

import models

from rest_framework_gis import serializers as gis_serializers

class LinkSerializer(gis_serializers.GeoFeatureModelSerializer):

    class Meta:

        model = models.Link

        geo_field = "geom"

        fields = ('id', )

class LinkFlowSerializer(serializers.ModelSerializer):

    class Meta:

        model = models.LinkFlow

        fields = ('link_id', 'flow', 'flow_type')

```

The error is being thrown in the serializer.py file in the django-rest-frame-work-gis project on this line:

from rest_framework.serializers import ModelSerializer, ModelSerializerOptions 

My Investigation

---

I've looked through the django-rest-framework code, and I can't find a definition for ModelSerializerOptions class in serializers.py or any of the other files.

I was hoping for some suggestions on what to look into next.

Thanks,

Lei

DRF-GIS is not yet compatible with DRF 3.0. If you want to use it you'll have to use DRF 2.x for the time being.

Thanks, that was the problem.

Any plans to support DRF 3.0 soon?

Personally, I'm not in urgent need, so I'm not planning to do it urgently.

I'd say I'll definitely do it before mid january, but i cannot guarantee.
