Python eve ?where 查询 returns 空结果

Question

我有一个名为 Case 的 mongo 集合，其中包含以下记录：

{
    _updated: "Tue, 26 Jul 2016 10:47:34 GMT",
    user_id: "ronaldo",
    client: "webapp",
    _links: {
        self: {
            href: "case/57972a253d73f156b5427ac3",
            title: "case"
        }
    },
    _created: "Tue, 26 Jul 2016 09:15:17 GMT",
    _id: "57972a253d73f156b5427ac3",
    _etag: "e85847955b97c2a339628071397ab4cafd959062"
},
{
    _updated: "Tue, 26 Jul 2016 09:20:50 GMT",
    user_id: "578ca6e4daaf452467ffa9f2",
    client: "webapp",
    _links: {
        self: {
            href: "case/57972b723d73f156b5427ac4",
            title: "case"
        }
    },
    _created: "Tue, 26 Jul 2016 09:20:50 GMT",
    _id: "57972b723d73f156b5427ac4",
    _etag: "6a6066ed62c91d0f79bbf3a362b567f8e7710f63"
}

以下查询returns数据正确：

http://localhost:8000/case?where={"user_id":"ronaldo"}

而下面的查询 returns 空结果集：

http://localhost:8000/case?where={"user_id":"578ca6e4daaf452467ffa9f2"}

Please note that If I do the query directly in mongo, it works:
db.case.find({user_id: "578ca6e4daaf452467ffa9f2"})

请帮忙！

看起来您的 user_id 有时可能包含类似 objectid 的字符串。尝试在您的资源设置中设置 query_objectid_as_string。引用 docs:

When [query_objectid_as_string is] enabled the Mongo parser will avoid automatically casting electable strings to ObjectIds. This can be useful in those rare occurrences where you have string fields in the database whose values can actually be casted to ObjectId values, but shouldn’t. It effects queries (?where=) and parsing of payloads. Defaults to False.
