Question

[解决]

我刚刚解决了这个问题

class articleViewSet(viewsets.ModelViewSet):
    queryset = article.objects.all()
    serializer_class = articleSerializer

    def destroy(self, request, *args, **kwargs):
        password = request.data.get('password')
        article_id = request.data.get('article')
        instance = self.get_object()
        if password == instance.password:
            self.perform_destroy(instance)
            return Response(status=status.HTTP_204_NO_CONTENT)
        return Response(status=status.HTTP_304_NOT_MODIFIED)

使用密码参数请求，已成功删除。

[delete.py]

import requests

r = requests.delete("http://mysite/article/45/")

[views.py]

class articleViewSet(viewsets.ModelViewSet):
    queryset = article.objects.all()
    serializer_class = articleSerializer

    def delete(self, pk, request):
        method = self.request.method
        article = article.objects.get(pk=pk)
        if method == 'DELETE':
            if request.password == article.password:
                article.delete()
                return Response(status=status.HTTP_200_OK)
        return Response(status=status.HTTP_304_NOT_MODIFIED)

我想在删除数据时添加一些条件。

这是我的models.py和serializers.py

[serializers.py]

class articleSerializer(serializers.ModelSerializer):
    userkey = serializers.CharField(write_only=True)
    password = serializers.CharField(write_only=True)
    class Meta:
        model = article
        fields = ('articleNo', 'content', 'date', 'userkey', 'password')

[models.py]

class article(models.Model):
    articleNo = models.AutoField(primary_key=True)
    userkey = models.CharField(max_length=50, null=False)
    content = models.CharField(max_length=500, null=False)
    password = models.CharField(max_length=20, null=False, default='1234')
    date = models.DateTimeField(auto_now_add=True)

例如，下面的数据在数据库中。

| articleNo | content           | date                       | userkey |password|
---------------------------------------------------------------------------------
|        33 | test article      | 2018-03-11 05:00:15.428661 | a1b2c3d4 | 1234  |

何时＆＃34;删除＆＃34;方法请求，我想比较请求的密码和文章的密码。如果相同，则会删除数据。

参考文件，我想我必须覆盖def delete()。

但我不知道该怎么做。

我该如何解决这个问题？

感谢。

Answer 1

假设您有一个删除有效负载，如下所示，

request_payload = {
    "password": "request's password",
    "article": some_integer_value_article_instance,
    # other data
}

你的意见就像是

class articleViewSet(viewsets.ModelViewSet):
    queryset = article.objects.all()
    serializer_class = articleSerializer

    def delete(self, pk, request):
        password = request.data.get('password')
        article_id = request.data.get('article')
        article_instance = article.objects.get(id=article_id)
        if password == article_instance.password:
            article_instance.delete()
            return Response(status=status.HTTP_200_OK)
        return Response(status=status.HTTP_304_NOT_MODIFIED)

Answer 3

在views.py文件中，您可以设置一个条件，该方法在删除方法时起作用。

if request.method == 'DELETE':
    #your code here

Django Rest框架条件删除
