Django Tastypie - 仅包含对象详细信息的资源

Question

在带有 Tastypie 的 Django 中，有没有办法配置资源以使其仅显示对象详细信息？

我想要一个 url /user，它返回经过身份验证的用户的详细信息，而不是包含单个用户对象的列表。我不想使用/users/<id> 来获取用户的详细信息。

这是我的代码的相关部分：

from django.contrib.auth.models import User
from tastypie.resources import ModelResource

class UserResource(ModelResource):

    class Meta:
        queryset        = User.objects.all()
        resource_name   = 'user'
        allowed_methods = ['get', 'put']
        serializer      = SERIALIZER      # Assume those are defined...
        authentication  = AUTHENTICATION  # "
        authorization   = AUTHORIZATION   # "

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

我可以通过使用以下资源方法的组合来做到这一点

• override_urls
• apply_authorization_limits

示例用户资源

#Django
from django.contrib.auth.models import User
from django.conf.urls import url

#Tasty
from tastypie.resources import ModelResource

class UserResource(ModelResource):
    class Meta:
        queryset = User.objects.all()
        resource_name = 'users'

        #Disallow list operations
        list_allowed_methods = []
        detail_allowed_methods = ['get', 'put', 'patch']

        #Exclude some fields
        excludes = ('first_name', 'is_active', 'is_staff', 'is_superuser', 'last_name', 'password',)

    #Apply filter for the requesting user
    def apply_authorization_limits(self, request, object_list):
        return object_list.filter(pk=request.user.pk)

    #Override urls such that GET:users/ is actually the user detail endpoint
    def override_urls(self):
        return [
            url(r"^(?P<resource_name>%s)/$" % self._meta.resource_name, self.wrap_view('dispatch_detail'), name="api_dispatch_detail"),
        ]
