Question

我正在开发一个简单的博客项目来学习django rest框架。我正在按照教程进行操作，但有些事情似乎没有按预期工作。

这里我试图列出，创建，更新，检索和销毁对象。但是，我只能列出并创建。其他三个功能没有按预期工作。

以下是我的应用： -

models.py

from django.db import models

class Blog(models.Model):
    title = models.CharField(max_length = 30)
    author = models.CharField(max_length = 50)
    tags = models.CharField(max_length = 10)
    post = models.TextField(max_length = 100)

    class Meta:
        ordering = ('title',)

    def __str__(self):
        return self.title

serializers.py

from rest_framework import serializers
from loginapp.models import *

class BlogSerializer(serializers.ModelSerializer):
    class Meta:
        model = Blog

views.py

from django.shortcuts import render
from django.contrib.auth.models import User
from rest_framework.authentication import TokenAuthentication, BasicAuthentication, SessionAuthentication
from rest_framework.permissions import IsAuthenticated
from rest_framework.response import Response
from rest_framework.request import Request
from rest_framework.views import APIView
from rest_framework import generics
from loginapp.models import *
from loginapp.serializers import *
# Create your views here.

class BlogListCreate(generics.ListCreateAPIView):   
    queryset = Blog.objects.all()   
    serializer_class = BlogSerializer


class BlogDetail(generics.RetrieveUpdateDestroyAPIView):    
    queryset = Blog.objects.all()   
    serializer_class = BlogSerializer

urls.py

from django.conf.urls import url
from loginapp import views

urlpatterns = [
    url(r'^loginapp/(?P<pk>[0-9]+)/', views.BlogDetail.as_view()),
    url(r'^loginapp/', views.BlogListCreate.as_view()),

]

你可以帮我解决这个问题吗？

注意：页面中没有可用于更新/删除/检索的选项。即使我通过url传递id值，它也不会检索预期的记录。抱歉，我无法附加HTML页面。

如果您想要所有CRUD功能，请将views.py更改为

from rest_framework import viewsets
from rest_framework import permissions

class BlogViewSet(viewsets.ModelViewSet):   
    queryset = Blog.objects.all()   
    serializer_class = BlogSerializer
    # POST/PUT/PATCH will by default not be enabled in DRF ui 
    # unless  you are logged in so set permission classes to AllowAny or
    # empty(permission_classes = ()), Do not do it in Production   
    permission_classes = (permissions.AllowAny,)

和urls.py到

from loginapp.view import BlogViewSet
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'loginapp', BlogViewSet)
urlpatterns = [
    url(r'^', router.urls),
]

无法使用django rest框架进行更新，发布和删除
