現在、EndpointsModel を使用して、AppEngine 上のすべてのモデル用の RESTful API を作成しています。RESTful であるため、これらの API には繰り返しのコードが多くあり、これを回避したいと考えています。
例えば:
class Reducer(EndpointsModel):
name = ndb.StringProperty(indexed=False)
@endpoints.api(
name="bigdata",
version="v1",
description="""The BigData API""",
allowed_client_ids=ALLOWED_CLIENT_IDS,
)
class BigDataApi(remote.Service):
@Reducer.method(
path="reducer",
http_method="POST",
name="reducer.insert",
user_required=True,
)
def ReducerInsert(self, obj):
pass
## and GET, POST, PUT, DELETE
## REPEATED for each model
それらをジェネリックにしたい。だから私はクラスにメソッドを動的に追加しようとします。私がこれまでに試したこと:
from functools import partial, wraps
def GenericInsert(self, obj, cls):
obj.owner = endpoints.get_current_user()
obj.put()
return obj
# Ignore GenericDelete, GenericGet, GenericUpdate ...
import types
from functools import partial
def register_rest_api(api_server, endpoint_cls):
name = endpoint_cls.__name__
# create list method
query_method = types.MethodType(
endpoint_cls.query_method(
query_fields=('limit', 'pageToken'),
path="%ss" % name,
http_method="GET",
name="%s.list" % name,
user_required=True
)(partial(GenericList, cls=endpoint_cls)))
setattr(api_server, "%sList", query_method)
# create insert method
# ...
register_rest_api(BigDataApi, Reducer)
しかし、のデコレータとパーシャルの'functools.partial' object has no attribute '__module__' exception.
間にいくつかの競合があるためだと思います。endpoints.method
しかし、それを回避する方法がわかりません。
