在Google Cloud Datastore的开发人员控制台中按“键”过滤的正确语法是什么？

Question

This is an old question on this topic, now it has new problem.

Update: Google update its console and this problem is solved. The right format is "Key('$YOUR_KIND'," + " " + $YOUR_VALUE + ")" . Please note that there must be only one space after comma, if your key is number then just write it, for example: Key('my_kind', 1234567890) , String type key need be quoted, for example: Key('MyKind', 'test_01') .

Original question. Key('MyKind', 1) does not work, it shows Your request included invalid parameters without any meaningful information, I have to catch the network response and get the detail error description __key__ filter namespace is but query namespace is test01 . Notice that there are two spaces between "... namespace is" and "but query ...", seems that I should add namespace in the key. Does anyone know how to add it or some other way to solve this problem?

Thank you very much.

Answer 1

SELECT * FROM Kind where __key__ = KEY('Kind', <id or name>)

So your example of Key('MyKind', 1) should have KEY as uppercase. If you're using ids, then 1 is ok, if you're using names (ie strings) you must quote it.
