tl;dr: is it possible, with endpoints-proto-datastore, to receive a list with objects from a POST and insert it in the db?
Following the samples, when building my API i didn't got how could i let the users POST a list of objects so that i could be more efficient about putting a bunch of data in the db using ndb.put_multi, for example.
From this comment here at endpoints_proto_datastore.ndb.model i imagine that it is not possible with how it is designed. Am i right or i am missing something?
Extending the sample provided by endpoints achieved the desired with:
class Greeting(messages.Message):
message = messages.StringField(1)
class GreetingCollection(messages.Message):
items = messages.MessageField(Greeting, 1, repeated=True)
# then inside the endpoints.api class
@endpoints.method(GreetingCollection, GreetingCollection,
path='hellogretting', http_method='POST',
name='greetings.postGreeting')
def greetings_post(self, request):
result = [item for item in request.items]
return GreetingCollection(items=result)

See the docs about POSTing into the datastore, your only issue is that your models aren't EndpointsModels. Instead define a datastore model for both your Greeting and GreetingCollection:
from endpoints_proto_datastore.ndb import EndpointsModel
class Greeting(EndpointsModel):
message = ndb.StringProperty()
class GreetingCollection(EndpointsModel):
items = ndb.StructuredProperty(Greeting, repeated=True)
Once you've done this, you can use
class MyApi(remote.Service):
# ...
@GreetingCollection.method(path='hellogretting', http_method='POST',
name='greetings.postGreeting')
def greetings_post(self, my_collection):
ndb.put_multi(my_collection.items)
return my_collection
