AttributeError with django 1.11.5 models

[hadeelsharaf]

I had this error while creating a service to a django project :
AttributeError: 'Options' object has no attribute get_all_field_names
this is the code:

User = get_user_model()


class Container(DjangoComplexModel):
  class Attributes(DjangoComplexModel.Attributes):
      django_model = User
      django_exclude = [] 

this part of the tracback:

from .services import hello_world_service, app, HelloWorldService
File "/home/hadeel/projects/sadie_service/service/services.py", line 50, in <module>
  class Container(DjangoComplexModel):

  meta.get_all_field_names())
AttributeError: 'Options' object has no attribute 'get_all_field_names'

I had the same error using the latest released spyne version (2.12.14), but with current master everything works fine.

Perhaps a new version of spyne should be released and published on pypi?

Replace

unknown_fields_names = field_names.difference( 
    meta.get_all_field_names())

to

unknown_fields_names = field_names.difference(
    [f.name for f in meta.get_fields()])
