django + django_filter过滤设置无效的问题

django + django_filter过滤设置无效的问题

整个配置完后，不出错，但是就是没有想要的效果，麻烦大家给看看是咋回事。

如图，本来只查询千字文，结果出来的是整个列表；

以下为代码，专门为搜索写了一个BookSearchView：

模型：

class Book(models.Model):
    title = models.CharField(max_length=32,verbose_name="书籍名称")
    price = models.IntegerField(verbose_name="价格")
    pub_date = models.DateField(verbose_name="出版日期")
    
    bread = models.IntegerField(verbose_name="阅读量") 
    bcomment = models.IntegerField(verbose_name="评论量") 
    
    publish = models.ForeignKey("Publish",on_delete=models.CASCADE,verbose_name="出版社")
    authors = models.ManyToManyField("Author",verbose_name="作者")

    def __str__(self):
        return self.title

实现：

from rest_framework.generics import GenericAPIView,ListCreateAPIView,RetrieveUpdateDestroyAPIView
from django_filters import rest_framework as filters
from django_filters.rest_framework import DjangoFilterBackend

class BookView(ModelViewSet):
# class BookView(ListCreateAPIView):
    queryset = Book.objects.all()
    serializer_class = BookSerializer

class BookSearchView(ListCreateAPIView):
    queryset = Book.objects
    serializer_class = BookSerializer
    filter_backends = [DjangoFilterBackend]
    filter_fields = ['title']

看了各种资料都不知道问题在哪里。

• 给你找了一篇非常好的博客，你可以看看是否有帮助，链接：django filter 多条件查询

settings.py
INSTALLED_APPS = [
    'rest_framework',
    'django_filters',
]

views.py
from django_filters import rest_framework as filters

class CourseListView(ListAPIView):
    queryset = models.Course.objects.filter(is_show=True, is_deleted=False)
    serializer_class = CourseModelSeralizer
    filter_backends = (filters.DjangoFilterBackend,)
    filterset_fields = ('course_category',)

新版改了字段名称
可以看一下官方文档
