云数据库的nin命令怎么对_id进行排除操作？ - WXOPEN Club

let ninArr = [‘5cef8721d2a18eed506bf34e’,‘5cef8721d2a18eed506bf34d’]

coll.where({

//此处nin代码怎么不起作用？

_id: _.nin([ninArr])

}).get({

success: console.log,

fail: console.error

})

nin命令可以对_id进行排除操作，可能是我的格式写的不对，谢谢解答！

const cloud = require('wx-server-sdk')

cloud.init()

const db = cloud.database()

const collStep = db.collection('step')

const _ = db.command

exports.main = async(event, context) => {

try {

return await collStep.where({

//此句nin()无效

_id: _.nin(["5d27ee9578f8e29f4acb73d8","5d27ee9578f8e29f4acb73da"]),

}).limit(100).orderBy('order', 'asc').get()

} catch (e) {

console.error(e)

}

[ninArr]改成ninArr
