Django restframwork获取列表详情

z哎Django restframwork中就有一个类可以获取列表的详情内容，只有两行代码就可以搞定，在浏览器测试是ok的。但是这样的接口给前端，前端点击详情然后会将models.表名.objects.all()的所有内容重新放在了这个数组中。以至于前端点击详情拿到的并不是单个id对应的内容。所以稍微重写一下就好。看一下代码。本来就是一个数据表，列表页数据少，详情回去的数据多一点而已。

class Upload_filep(models.Model):

    """上传项目模型"""

    name = models.CharField(verbose_name='项目名', max_length=32)

    title = models.TextField(verbose_name='项目描述')

    upload_files = models.FileField(upload_to="upload/")

    img = models.ImageField(upload_to="upload/")

    address = models.CharField(max_length=64, verbose_name='地址', null=True, blank=True)

    add_time = models.DateTimeField(default=datetime.now, verbose_name='创建时间')
router = DefaultRouter()

router.register(r'show_workPubs_detail',Mode_DetailViewSet,base_name="mode_detail")

urlpatterns = [

    path('admin/', admin.site.urls),

    url(r'^',include(router.urls)),

]+ static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

url.py

seiializers.py

class Show_workPublishedModelSerialiazer(serializers.ModelSerializer):

    class Meta:

        model = Upload_filep

        fields = ("id","name","title","img","upload_files","address")

        search_fields = ('name','title')

　　view.py(原Django restframwork中只写queryset和serializer_class就可以获取，但是前端拿到的并不是单个id对应的数据，所以重写get_queryset(self)就好)

class Mode_DetailViewSet(mixins.ListModelMixin, viewsets.GenericViewSet):

    # 通过三维城市的id，获取三维城市的详情

    queryset = Upload_filep.objects.all()

    serializer_class = Show_workPublishedModelSerialiazer

    def get_queryset(self):

        id = self.request.GET.get('id')

        if id is not None:

            return self.queryset.filter(id=id)

        return self.queryset

到此，列表详情的获取就可以完成
