[英]Google app engine OR QUERY ids with Objectify
Hello I am using objectify with google app engine. 您好,我在Google App Engine中使用objectify。 I've seen that I can do something like this one
我已经看到我可以做这样的事情
List<Car> cars = ofy().load().type(Car.class).filter("year in", yearList).list();
Which achieves an OR QUERY result However when I try to query by id (set as a Long type), I get an exception and that only filtering by Long or String values is allowed. 达到OR查询的结果但是,当我尝试按id(设置为Long类型)查询时,出现异常,并且仅允许按Long或String值进行过滤。 More specific
更加具体
java.lang.IllegalArgumentException: Id filter values must be Long or String
Is it possible to make an OR QUERY by id filtering? 是否可以通过ID过滤来进行OR查询?
When querying multiple ids use .. 查询多个ID时,请使用..
ofy().load().type(Car.class).ids(IDs);
... where IDs is a List of your ids. ...其中ID是您ID的列表。
