[英]How to “POST” ndb.StructuredProperty?
I have following EndpointsModels
, 我有以下
EndpointsModels
,
class Role(EndpointsModel):
label = ndb.StringProperty()
level = ndb.IntegerProperty()
class Application(EndpointsModel):
created = ndb.DateTimeProperty(auto_now_add=True)
name = ndb.StringProperty()
roles = ndb.StructuredProperty(Role, repeated=True)
and an API method: 和一个API方法:
class ApplicationApi(protorpc.remote.Service):
@Application.method(http_method="POST",
request_fields=('name', 'roles'),
name="create",
path="applications")
def ApplicationAdd(self, instance):
return instance
When I try to POST this data: 当我尝试发布此数据时:
{ "name": "test", "roles": [{ "label": "test", "level": 0 }] }
I'm getting an error ( trace ): 我收到一个错误( 跟踪 ):
AttributeError: 'Role' object has no attribute '_Message__decoded_fields'
AttributeError:“角色”对象没有属性“ _Message__decoded_fields”
I tried to use EndpointsAliasProperty
: 我尝试使用
EndpointsAliasProperty
:
class ApplicationApi(protorpc.remote.Service):
...
def roless_set(self, value):
logging.info(value)
self.roles = DEFAULT_ROLES
@EndpointsAliasProperty(setter=roless_set)
def roless(self):
return getattr(self, 'roles', [])
which results in 400 BadRequest
结果是
400 BadRequest
Error parsing ProtoRPC request (Unable to parse request content: Expected type
<type 'unicode'>
for field roless, found {u'level': 0, u'label': u'test'} (type<type 'dict'>
))解析ProtoRPC请求时出错(无法解析请求内容:字段角色的预期类型
<type 'unicode'>
type'unicode<type 'unicode'>
,找到{u'level':0,u'label':u'test'}(类型<type 'dict'>
type'dict<type 'dict'>
))
If I add property_type
to the alias: 如果我将
property_type
添加到别名:
@EndpointsAliasProperty(setter=roless_set, property_type=Role)
I'm getting server error again ( trace ): 我再次遇到服务器错误( 跟踪 ):
TypeError: Property field must be either a subclass of a simple ProtoRPC field, a ProtoRPC enum class or a ProtoRPC message class.
TypeError:属性字段必须是简单ProtoRPC字段的子类,ProtoRPC枚举类或ProtoRPC消息类。 Received Role
<label=StringProperty('label'), level=IntegerProperty('level')>
.收到的角色
<label=StringProperty('label'), level=IntegerProperty('level')>
。
Is there a way to "convert"
EndpointsModel
to
ProtoRPC message class
?
有没有一种方法可以将
Are there any better solutions for creating models with EndpointsModel
转换为
ProtoRPC message class
?
StructuredProperty
using POST data? 是否存在使用POST数据使用
StructuredProperty
创建模型的更好解决方案? I couldn't find any examples for this, if someone knows any links, please share (: 我找不到任何示例,如果有人知道任何链接,请分享(:
After some digging through source code, I found EndpointsModel.ProtoModel()
that can be used to convert ndb.Model to ProtoRPC message class 在仔细研究了源代码之后,我发现了
EndpointsModel.ProtoModel()
可用于将ndb.Model转换为ProtoRPC消息类。
@EndpointsAliasProperty(setter=roless_set, property_type=Role.ProtoModel())
This resolves issue with EndpointsAliasProperty
workaround, but the problem remains... 这解决了
EndpointsAliasProperty
解决方法的问题,但问题仍然存在...
Check this repo: https://github.com/zdenulo/epd-error-example . 检查此仓库: https : //github.com/zdenulo/epd-error-example 。 Here I was demonstrating error in endpoints-proto-datastore which in latest version should be fixed.
在这里,我演示了端点原始数据存储区中的错误,该错误在最新版本中应该得到修复。 So upgrade in repository to latest endpoints-proto-datastore and you should have working example which similar to what you want to achieve.
因此,在存储库中升级到最新的终结点原始数据存储,您应该有一个工作示例,该示例与您要实现的目标类似。
Hey Sasxa has there been a fix for this as far as you know? 据您所知,Sasxa对此有修复程序吗? I am currently dealing with the same issue, and I can start a new thread for this discussion if nothing has been found.
我目前正在处理同一问题,如果未发现任何问题,则可以启动新线程进行讨论。
