tastypie 发布和完整示例

Question

是否有完整的 tastypie django 示例站点和设置可供下载？我一整天都在努力解决这个问题。我有以下代码。基本上，我有一个使用 ajax 处理的 POST 表单。当我单击表单上的“提交”并且运行 ajax 请求时，调用返回“POST http: //192.168.1.110:8000/api/private/client_basic_info/ 404（未找到）”我我认为 URL 配置正确。我可以访问 http://192.168.1.110:8000/api/private/client_basic_info /?format=json 就可以了。我是否遗漏了一些设置或在我的方法中犯了一些基本错误？我的意图是每个用户只能填写/修改一张且只有一张“客户基本信息”表格/模型。

页面：

{% extends "layout-column-100.html" %}

            $('#client_basic_info_form').submit(function (e) {

                form.find('span.error-message, span.success-message').remove()

编辑：

我的资源文件现在是：

from residence.models import ClientBasicInfo
from residence.forms.profiler import ClientBasicInfoForm

from tastypie import fields
from tastypie.resources import ModelResource
from tastypie.authentication import BasicAuthentication
from tastypie.authorization import DjangoAuthorization, Authorization

class UserResource(ModelResource):

    class Meta:
        queryset = User.objects.all()
        resource_name = 'user'
        fields = ['username']
        filtering = {
            'username': ALL,
        }
        include_resource_uri = False
        authentication = BasicAuthentication()
        authorization = DjangoAuthorization()

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

    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', ]
        #detail_allowed_methods = ['get', 'post', 'put', 'delete']

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

我将 ClientBasicInfo 的用户字段设置为可为空，并且 POST 似乎可以工作。我现在想尝试更新该条目。那只是将 pk 附加到 ajax url 吗？例如/api/private/client_basic_info/21/?当我提交该表单时，我收到一条 501 NOT IMPLEMENTED 消息。我到底还没有实施什么？我正在子类化 ModelResource，它应该根据文档实现所有与 ORM 相关的函数。

Answer 1

好吧，我明白了。我不小心。 AJAX 请求类型应该是“PUT”来处理 501 未实现错误（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。
