未指定`basename`参数

如何解决未指定`basename`参数

我由django restframework创建了一个新项目项目名称=框架 th project_app name = framework

fram.urls.py：

"""frame URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.1/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('',views.home,name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('',Home.as_view(),name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include,path
    2. Add a URL to urlpatterns:  path('blog/',include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path,re_path
from django.conf.urls import include,url
from framework.views import myviewset
from rest_framework import routers

router = routers.DefaultRouter();
router.register('task',myviewset)

urlpatterns = [
    path('admin/',admin.site.urls),re_path(r'',include(router.urls)),]

框架模型。py：

from django.db import models

# Create your models here.
class Task (models.Model):
    task_name=models.CharField(max_length='200')
    task_desc=models.CharField(max_length='200')
    date_created=models.DateTimeField(auto_Now=True)

serializer.py

from .models import Task
from rest_framework import serializers


class TaskSerializers(serializers.ModelSerializer):
    class Meta:
        model = Task
        fields = ('id','task_name','task_desc')

views.py：

from django.shortcuts import render
from .serializer import TaskSerializers
from rest_framework import viewsets
from .models import Task


# Create your views here.
class myviewset(viewsets.ModelViewSet):
    query = Task.objects.all().order_by('date_created')

    serializer_class = TaskSerializers

admin.py：

from django.contrib import admin
from .models import Task


admin.site.register(Task)
# Register your models here.

setting.py：

INSTALLED_APPS = [
    'framework','rest_framework','django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles',]

当我在CMD中运行服务器时错误出现：

AssertionError：basename参数未指定，并且由于没有.queryset属性，因此无法从视图集中自动确定名称。

解决方法

您应该在视图集中指定queryset属性而不是query。例如（类别名称大小写已更改为符合PEP8）：

class MyViewSet(viewsets.ModelViewSet):
    queryset = Task.objects.all().order_by('date_created')

    serializer_class = TaskSerializers

文档：https://www.django-rest-framework.org/api-guide/viewsets/#modelviewset

此外，我建议您在注册视图集时始终指定basename。像这样：

router = routers.DefaultRouter();
router.register('task',MyViewSet,basename='tasks')

https://www.django-rest-framework.org/api-guide/routers/#usage

basename-用于创建的URL名称的基础。如果未设置，则将基于视图集的queryset属性自动生成基本名称。请注意，如果视图集不包含queryset属性，则在注册视图集时必须设置basename。
