"error_message"："environments_environment.client_id不能为空“

Question

当我通过curl创建数据时，我得到了以下错误。

"error_message": "environments_environment.client_id may not be NULL"

我的django模型是

class Client(models.Model):
    name = models.CharField(max_length=100)
    def __unicode__(self):
        return u'%s' % self.name
class Environment(models.Model):
    client = models.ForeignKey(Client)
    name = models.CharField(max_length=100)
    def __unicode__(self):
        return u'%s:%s' % (self.client.name, self.name)

我的资源是，

class ClientResource(ModelResource):

    class Meta:
        queryset = Client.objects.all()
        resource_name = 'clients'
        allowed_methods = ['get', 'put', 'delete', 'post']
        authorization = Authorization()


class EnvironmentResource(ModelResource):

    client = fields.ForeignKey(ClientResource, 'clients', full=True, null=True, blank=True)

    class Meta:

        queryset = Environment.objects.all()
        resource_name = 'environments'
        allowed_methods = ['get', 'put', 'delete', 'post']
        authorization = Authorization()

在创建客户端之后，我尝试通过

curl -X POST  --data '{"client":"/api/v1/clients/1/","name":"rpcenv"}' \
   -H 'Authorization: xxxxxxxx'                                        \
   -H 'Content-Type: application/json;charset=UTF-8'                   \
   http://example.com/api/v1/environments/

但是输出结果看起来像是，

"error_message": "environments_environment.client_id may not be NULL"

请任何人能帮助我解决这个错误。

它提供了"environments_environment.client_id may not be NULL"，因为

client = models.ForeignKey(Client)

它采用默认的null=False.So，您应该设置客户端id。或者如果你不想这么做

client = models.ForeignKey(Client, null=True, blank=True)
