在GraphQL食谱示例中的Django过滤器错误

Question

我目前正在通过石墨烯教程学习GraphQL。

但是我遇到了这个错误，当我试图运行

错误：

AssertionError: 'order_by' is not compatible with the 'fields' dict syntax. Use OrderingFilter instead. 

让我大胆的错误Asse田的最后一行：“ORDER_BY”不是与'fields'字典句法兼容。改用OrderingFilter。

在我的成分

/schema.py

# cookbook/ingredients/schema.py 
from graphene import relay, ObjectType, AbstractType 
from graphene_django import DjangoObjectType 
from graphene_django.filter import DjangoFilterConnectionField 

from .models import Category, Ingredient 


# Graphene will automatically map the Category model's fields onto the CategoryNode. 
# This is configured in the CategoryNode's Meta class (as you can see below) 
class CategoryNode(DjangoObjectType): 
    class Meta: 
     model = Category 
     filter_fields = ['name', 'ingredients'] 
     filter_order_by_field = ['name'] 
     interfaces = (relay.Node,) 


class IngredientNode(DjangoObjectType): 
    class Meta: 
     model = Ingredient 
     # Allow for some more advanced filtering here 
     filter_fields = { 
      'name': ['exact', 'icontains', 'istartswith'], 
      'notes': ['exact', 'icontains'], 
      'category': ['exact'], 
      'category__name': ['exact'], 
     } 
     order_by_field = ['name', 'category__name'] 
     interfaces = (relay.Node,) 


class Query(AbstractType): 
    category = relay.Node.Field(CategoryNode) 
    all_categories = DjangoFilterConnectionField(CategoryNode) 

    ingredient = relay.Node.Field(IngredientNode) 
    all_ingredients = DjangoFilterConnectionField(IngredientNode) 

Django的过滤器版本0.15.3

我试图从官方石墨烯回购克隆的例子，它python2.7运行良好。但是在python3.5中，相同的代码无法工作。我怀疑django-filter中的某些东西已经改变，导致不兼容。在python2.7中，django-filter版本是0.11.0。有谁知道如何使它在0.15.3工作？

这是一个报道GitHub上的问题，已经得到解决：https://github.com/graphql-python/graphene-django/issues/8

升级到石墨烯1.1，你应该是好去。
