Question

所以我跟着DjangoREST framewok网站上的Quickstart Guide，最后得到了以下代码：

serializers.py：

class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
    model = User
    fields = ('url', 'username', 'email', 'groups')


class GroupSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
    model = Group
    fields = ('url', 'name')

views.py：

class UserViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows users to be viewed or edited.
"""
queryset = User.objects.all().order_by('-date_joined')
serializer_class = UserSerializer

class GroupViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows groups to be viewed or edited.
"""
queryset = Group.objects.all()
serializer_class = GroupSerializer

urls.py：

router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)
router.register(r'rooms', views.RoomViewSet)
router.register(r'devices', views.DeviceViewSet)
router.register(r'deviceTypes', views.DeviceTypeViewSet)

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls',  namespace='rest_framework'))
]

现在一切正常，但我无法找到如何删除或更新用户或组，似乎我只能添加用户和组并查看它们。所以我的问题是：如何修改此代码以删除/更新用户和组？

Answer 1

代码很好，您只需要分别使用PUT和DELETE数据方法进行更新和删除（而不是GET/POST）

您可以在代码示例中看到docs

中的ModelViewSet

class SnippetViewSet(viewsets.ModelViewSet):
    """
    This viewset automatically provides `list`, `create`, `retrieve`,
    `update` and `destroy` actions.

以及ModelViewSet

的文档

ModelViewSet类提供的操作是.list()，.retrieve()，.create()，.update()，.partial_update()和.destroy()。

Answer 2

您必须使用方法DELETE执行HTTP请求，而不使用任何标题和正文。示例

<!DOCTYPE html>
<html>

<header>
  <h2 style="bottom: -130px">
    <a href="#" class=h ead-link> A  B  E  L</a>
  </h2>
  <div class="dropdown" style="float;right">
    <button class="dropbtn">Menu</button>
    <div class="dropdown-content" style="right;0">
      <a href="#">About </a>
      <a href="#">Portfolio</a>
      <a href="#">Contact</a>
    </div>
  </div>
  <div class="title"></div>
  <title>A B E L </title>
</header>

<body>
  <div id="hl-content" class="content"></div>

  <p>
    <span style="color:navajowhite">
      <b>Hello, Welcome to my website.</b>
    </span>
    <BR></BR>

    My name is Abel, a senior college student currently residing in the Bay Area. This portfolio will give you a good background about me including my specialties, expertise and even hobbies. As you can probably tell from the background pictures, I like traveling

  <p>This is my first ever website that I created using HTML and CSS, and it's a pleasure to finally be able to share it with you. I am happy to receive any feedback, recommendations or opportunities from you, so don't hesitate to contact me.</p>
  <div class="footer">
    <ul>
      <li><a href="#" target="#"> About</a></li>
      <li><a href="#" target="#">Portfolio</a></li>
      <li> <a href="#" target="#"> Contact </a></li>
    </ul>
  </div>
</body>

</html>

仅对比，创建将执行下一个CURL（注意标题“Content-Type”）：

curl -X DELETE http://127.0.0.1:8000/api/v1/persona/4/

干杯C：

Answer 3

使用“ curl”或“ httpie”执行删除或更新或任何其他请求。

示例：

http DELETE example.org/todos/7

or

curl -X "DELETE" http://www.url.com/page
