AttributeError: 'collections.OrderedDict' object has no attribute 'iteritems' from local DRF with swagger docs

[RadoRado]

I decided to test the following scenario with coredocs:

1. There's a DRF (latest version)
2. Added DRF Rest Swagger (latest version)
3. $ coredocs build "http://localhost:8000/docs?format=openapi" --format openapi results in the following exception:

Fetching schema file from 'http://localhost:8000/docs?format=openapi'.

Am I doing something wrong? 🐼

The JSON:

I have same issue.

Python 3.5.2
coredocs 0.0.6

[francescarpi]

Works fine with Python2.7. I think that isn't compatible with Python3.

This was already changed in 6c833c5#diff-8f109129a8007856c028c2dc21457a3c

But it's not in the latest release 0.0.6...master

So, for now, you'll need to work off of master

It would be very helpful if this fix could be uploaded to PYPI. What do you think?
