属性错误：'；模块'；对象没有属性'；DjangoFilterBackend'；

我正在使用django filter，但我得到以下错误：“module”对象没有属性“django FilterBackend” 我在下面发送我的代码：

Model.py

    from django.db import models

# Create your models here.
class searchModel(models.Model):
    email = models.CharField(max_length=25)
    password = models.CharField(max_length=10)
    image    = models.ImageField(upload_to='Image/')

    def __str__(self):
        return "%s" %  self.email

序列化程序.py

from rest_framework import serializers
from .models import searchModel

class searchserializer(serializers.ModelSerializer):
    image = serializers.ImageField(max_length=None, use_url=True)

    class Meta:
        model=searchModel
        fields=('email','password','image')

from rest_framework import viewsets
from .models import searchModel
from .serializers import searchserializer
#from django_filters.rest_framework import filters
from rest_framework import filters

class searchView(viewsets.ModelViewSet):
    queryset=searchModel.objects.all()
    serializer_class = searchserializer
    filter_backends = (filters.DjangoFilterBackend,filters.OrderingFilter,)
    filter_fields = ('email')
    ordering = ('email')

视图.py

from rest_framework import serializers
from .models import searchModel

class searchserializer(serializers.ModelSerializer):
    image = serializers.ImageField(max_length=None, use_url=True)

    class Meta:
        model=searchModel
        fields=('email','password','image')

from rest_framework import viewsets
from .models import searchModel
from .serializers import searchserializer
#from django_filters.rest_framework import filters
from rest_framework import filters

class searchView(viewsets.ModelViewSet):
    queryset=searchModel.objects.all()
    serializer_class = searchserializer
    filter_backends = (filters.DjangoFilterBackend,filters.OrderingFilter,)
    filter_fields = ('email')
    ordering = ('email')

使用来自的建议导入，您将执行以下操作：

import django_filters.rest_framework

class searchView(viewsets.ModelViewSet):
    ...
    filter_backends = (django_filters.rest_framework.DjangoFilterBackend,filters.OrderingFilter,)

或者，你也可以这样做

from django_filters.rest_framework import DjangoFilterBackend

class searchView(viewsets.ModelViewSet):
    ...
    filter_backends = (DjangoFilterBackend, filters.OrderingFilter,)

它会对你有用的 检查以下代码：

from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import filters

class TaskViewSet(viewsets.ModelViewSet):
  queryset = Task.objects.all().order_by('-date_created')
  serializer_class = TaskSerializers
  filter_backends = (DjangoFilterBackend, filters.OrderingFilter)

---

使用此导入将执行以下操作：

import django_filters.rest_framework
filter_backends = (django_filters.rest_framework.DjangoFilterBackend,)

---

相同-原因是FilterSet是django_过滤器的一部分，而不是rest_Framework，因此：

删除“从rest_框架导入过滤器”行 。。。

---

从django_filters导入FilterSet、AllValuesFilter、DateTimeFilter、NumberFilter

如果您只想通过电子邮件进行筛选，可以覆盖搜索视图中的get_queryset。“不工作”没有足够的信息来帮助您。从rest\u框架从导入视图集。模型从导入searchModel。序列化程序从django\u过滤器导入searchserializer#从django\u过滤器。rest\u框架从django\u过滤器导入过滤器。rest\u框架从rest\u框架导入过滤器类searchView（ViewSet.ModelViewSet）：queryset=searchModel.objects.all（）序列化程序\u类=searchserializer筛选器\u后端=（DjangoFilterBackend，filters.OrderingFilter）筛选器\u字段=（'email'）排序=（'email'）
