在羽毛JS中从rethinkdb查找嵌套的数组对象 [英] Find nested array-object from rethinkdb in feathers JS
问题描述
我有一个如下数据集
[{
"allowedusers": ["paul@abc.com"],
"id": "1"
},{
"allowedusers": ["kmahera@abc.com","rbajaniya@abc.com"],
"id": "2"
},{
"allowedusers": ["whatever@abc.com","rbajaniya@abc.com"],
"id": "3"
}]
，我有一个这样的查询-
and I have a Query like this -
http://localhost:3030/flowz $ limit = 5&allowedusers [$ in [] =rbajaniya@abc.com& $ skip = 0& $ select [] = id& $ select [] =允许的用户.
但是我没有得到所有包含 rbajaniya@abc.com 的对象.我如何制作查询以获取此信息.我想获得id = 2和id = 3作为响应.
But I am not getting all the objects that contain rbajaniya@abc.com . How can I craft my query to get this. I want to get id=2 and id=3 in response .
推荐答案
$ in 用于对照可能值的列表检查数据库中的单个值.您正在寻找的另一种方法是通过 feathers-rethinkdb 特定的 $ contains运算符:
$in is to check a single value in the database against a list of possible values. What you are looking for is the other way around which can be done through the feathers-rethinkdb specific $contains operator:
http://localhost:3030/flowz?$limit=5&allowedusers[$contains]=rbajaniya@abc.com&$skip=0&$select[]=id&$select[]=alloweduser
