我有以下OneToOne映射到User表的CustomerProfile模型:
class CustomerProfile(models.Model):
'''Profile details of the customers. All extra details are mentioned
here.'''
user = models.OneToOneField(User, related_name='profile')
phone = models.CharField(max_length=200, null=True, blank=True)
class Meta:
app_label = 'testapp'
def __unicode__(self):
return unicode(self.user)
我使用Tastpye框架创建了REST API,并使用以下resource.py来获取用户及其配置文件详细信息
class UserResource(ModelResource):
'''Fetch user details'''
class Meta:
queryset = User.objects.all()
resource_name = 'user'
include_resource_uri = False
allowed_methods = ['get']
excludes = ['password','last_login','is_superuser','is_staff','date_joined']
filtering = {
'id': ['exact'],
'username': ['exact']
}
class CustomerProfileResource(ModelResource):
'''Fetch customer details and all coupons'''
class Meta:
queryset = CustomerProfile.objects.all()
resource_name = 'customer'
include_resource_uri = False
allowed_methods = ['get']
现在我想要的是使用单个API调用(/ user)用户也可以获取其个人资料详细信息。任何人都可以告诉你如何做到这一点。
仅供参考,我在UserResource类中添加了以下代码来实现此目的:
profile = fields.ToManyField('coin.api.CustomerProfileResource', 'profile', null=True, full=True)
但是我收到了这个错误:
{"error_message": "'CustomerProfile' object has no attribute 'all'", "traceback": "Traceback (most recent call last):\n\n File \"/home/rajeev/projects/bitbucket/coin/env/local/lib/python2.7/site-packages/tastypie/resources.py\", line 195, in wrapper\n response = callback(request, *args, **kwargs)
为了达到这个目的,我已经做了很多工作,但是没有找到能达到预期效果的东西。请提出一些解决方案。

幸运的是我通过点击和试用得到了答案:)
由于OneToOne映射将CustomerProfile资源映射到UserResouce,因此我们必须使用fields.ToOneField而不是fields.ToManyField,同时从UserResource执行反向关系,如下所示:
profile = fields.ToOneField('coin.api.CustomerProfileResource', 'profile', null=True, full=True)
但是如果有人能够清楚地阐明资源映射和反向映射,这对所有人都非常有帮助,显然django官方文档无法帮助我很多。

CustomerProfile以一对一的关系绑定到User,因此您应该在UserResource中使用fields.OneToOneField:
class UserResource(ModelResource):
'''Fetch user details'''
custom_profile = fields.OneToOneField(CustomerProfileResource, 'custom_profile', related_name='profile', full=True)
class Meta:
fields = ['id', 'username', 'custom_profile'] # other fields what you need
