POST django rest框架后重定向 [英] Redirect after POST django rest framework

问题描述

我正在通过Django表单向我的Django Rest Framework api提交POST请求。

I am submitting a POST request via django form to my Django Rest Framework api.

这是我的表单的摘要：

<form action="{% url 'entry-list' %}" method="POST" class="form" role="form">
{% csrf_token %}

{{form.as_p}}
<div class = "form-group">
    <button type="submit" class="save btn btn-default btn-block">Save</button>
</div>

views.py ：

views.py:

class entry_ViewSet(viewsets.ModelViewSet):
    queryset = Entry.objects.all()
    serializer_class= EntrySerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,IsOwnerOrReadOnly,)
    def perform_create(self, serializer):
        serializer.partial = True
        serializer.save(created_by=self.request.user)

我正在成功进行POST（并且已在数据库中创建项目），但是一旦保存，我将转到URL / api / entry / ，其中显示了我的带有Markdown的api。我想让它返回到特定的URL。

I am making a successful POST (and item is created in database), however once I save I go to the url /api/entry/ which shows my api w/Markdown. I'd like to have it go back to a specific url.

是否可以自定义 POST 重定向到是否成功？

Is there a way to customize where the POST redirect to if successful?

添加了序列化器：

class EntrySerializer(serializers.ModelSerializer):

    created_by = serializers.ReadOnlyField(source='created_by.username')
    class Meta:
        model = Entry
        fields = '__all__'
    def __init__(self, *args, **kwargs):
        super(EntrySerializer, self).__init__(*args, **kwargs)        
        for x in self.fields:
            self.fields[x].required = False     

推荐答案

viewsets.ModelViewSet 具有方法 create 返回 Response 对象。响应对象是 Django响应的子类型。因此，您可以使用 HttpResponseRedirect更改行为 放入 create 方法。例如：

viewsets.ModelViewSet has a method create that returns Response object. The response object is subtype of Django Response. Hence you can change behavior using HttpResponseRedirect into the create method. For example:

class entry_ViewSet(viewsets.ModelViewSet):
    queryset = Entry.objects.all()
    serializer_class= EntrySerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,IsOwnerOrReadOnly,)

    def create(self, request, *args, **kwargs):
        response = super(entry_ViewSet, self).create(request, *args, **kwargs)
        # here may be placed additional operations for
        # extracting id of the object and using reverse()
        return HttpResponseRedirect(redirect_to='https://google.com')

    def perform_create(self, serializer):
        serializer.partial = True
        serializer.save(created_by=self.request.user)
