Python Django REST中的UPDATE和DELETE操作

Question

我试图在Django Rest中实现简单的CRUD操作。我已经成功创建了GET和POST。现在，我想用PUT更新行数据并用DELETE删除一行。

目前，我的表格如下： -

id    item_1    item_2    item_3    date_created    date_modified

1     test1     test2     test3     16-12-2017      16-12-2017
2     ex1       ex2       ex3       16-12-2017      16-12-2017

API端点： - qazxsw poi

如果我们localhost/itemlist它返回项目列表。

如果我们GET localhost/itemlist与字段POST localhost/itemlist，item_1，item_2，它创建行。

现在，我想使用item_3更新特定行。就像，如果我想更新PUT的item_3的值

DELETE应删除item_1 == "test1"所在的行

item_1 == ex1

views.朋友 :

from django.conf.urls import url, include
from rest_framework.urlpatterns import format_suffix_patterns
from .views import ItemView

urlpatterns = {
    url(r'^itemlists/$', ItemView.as_view(), name="create"),       
}

urlpatterns = format_suffix_patterns(urlpatterns)

serialize认识.朋友

from rest_framework import generics
from .serializers import itemlistSerializer
from .models import itemlist   

class ItemView(generics.ListCreateAPIView):

    queryset = itemlist.objects.all()
    serializer_class = itemlistSerializer

    def perform_create(self, serializer):  
        serializer.save()

models.朋友

from rest_framework import serializers
from .models import itemlist

class itemlistSerializer(serializers.ModelSerializer):

    class Meta:
        """Meta class to map serializer's fields with the model fields."""
        model = itemlist
        fields = ('id', 'item_1', 'item_2', 'item_3', 'date_created', 'date_modified')
        read_only_fields = ('date_created', 'date_modified')

使用django viewsets：

views ETS.朋友

from django.db import models

class itemlist(models.Model):
    """This class represents the itemlist model."""
    item_1 = models.CharField(max_length=255, blank=True, unique=False)
    item_2 = models.CharField(max_length=255, blank=True, unique=False)
    item_3 = models.CharField(max_length=255, blank=True, unique=False)

    date_created = models.DateTimeField(auto_now_add=True)
    date_modified = models.DateTimeField(auto_now=True)

    def __str__(self):
        """Return a human readable representation of the model instance."""
        return "{}".format(self.item_1)

URLs.朋友

class ListItemViewSet(viewsets.ModelViewSet):
    serializer_class = itemlistSerializer
    queryset = itemlist.objects.all()
    http_method_names = ['get', 'post', 'put', 'delete', 'option']

    def get_queryset(self):
        request_user = self.request.user
        if not request_user.is_superuser:
            return self.queryset.filter(owner=request_user)

然后你应该能够发送put和delete请求。这适用于Django 1.9x。

还有一件事：请阅读

router = routers.DefaultRouter()
router.register(listitem', ListItemViewSet)

urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
]

。我们通常使用CamelCase作为类名。
