Question

是否有完整的tastypie django示例网站和设置可供下载？我一直在挣扎着整天缠着它。我有以下代码。基本上，我有一个用ajax处理的POST表单。当我在表单上单击“提交”并运行ajax请求时，调用将返回“POST http://192.168.1.110:8000/api/private/client_basic_info/ 404（未找到）”我认为我已将URL配置为正常。我可以访问http://192.168.1.110:8000/api/private/client_basic_info/?format=json就好了。我错过了一些设置或在我的方法中出现了一些基本错误吗？我的意图是每个用户可以填写/修改一个且仅修改一个“客户基本信息”表单/模型。

编辑：

我的资源文件现在是：

        fields = ['username']
        filtering = {

        }
        include_resource_uri = False
        authentication = BasicAuthentication()
        authorization = DjangoAuthorization()

    #def apply_authorization_limits(self, request, object_list):

    def dehydrate(self, bundle):
        forms_incomplete = []

        if ClientBasicInfo.objects.filter(user=bundle.request.user).count() < 1:
            forms_incomplete.append({'name': 'Basic Information', 'url': reverse('client_basic_info')})

        bundle.data['forms_incomplete'] = forms_incomplete
        return bundle


class ClientBasicInfoResource(ModelResource):
    # user = fields.ForeignKey(UserResource, 'user')

    class Meta:
        authentication = BasicAuthentication()
        authorization = DjangoAuthorization()
        include_resource_uri = False
        queryset = ClientBasicInfo.objects.all()
        resource_name = 'client_basic_info'
        validation = FormValidation(form_class=ClientBasicInfoForm)
        #list_allowed_methods = ['get', 'post', ]

    def apply_authorization_limits(self, request, object_list):
        return object_list.filter(user=request.user)

我使ClientBasicInfo的用户字段可以为空，POST似乎有效。我想尝试立即更新条目。那只是将pk附加到ajax网址吗？例如/ api / private / client_basic_info / 21 /？当我提交该表格时，我收到了501 NOT IMPLEMENTED消息。究竟我没有实现什么？我是ModelResource的子类，它应该根据文档实现所有与ORM相关的函数。

Answer 1

好的，我明白了。我不小心。 AJAX请求类型应该是“PUT”来处理501未实现的错误（我正在执行更新）。我还设置了一个自定义身份验证类来处理403错误。
