mongoose 嵌套查找匹配问题
先上 格式
var UserSchema = new mongoose.Schema({
name: {type: String, trim: true, require: true},
username: {type: String, unique: true, require: true, trim: true},
password: {type: String, require: true},
admin: {type: Boolean, default: false},
date: {type: Date, default: Date.now},
money: {type: Number, default: 0},
accounts: [{
status: {type: Number, require: true},
date: {type: Date, require: true},
thing: {type: String, require: true},
money: {type: Number, require: true}
}]
})
我存储的数据：
{
"_id" : ObjectId("58e086623bbf960351ac71d9"),
"name" : "xiaoming",
"username" : "xiao",
"password" : "ming",
"accounts" : [
{
"status" : 1,
"date" : ISODate("2017-03-23T02:30:24.837Z"),
"thing" : "play",
"money" : 10,
"_id" : ObjectId("58e086623bbf960351ac71e2")
},
{
"status" : 1,
"date" : ISODate("2017-03-24T02:30:24.837Z"),
"thing" : "sleep",

"thing" : "sleep",

},

],
"money" : 0,
"date" : ISODate("2017-04-02T05:04:34.550Z"),
"admin" : false,
"__v" : 0
}
重点 重点 我查询的语句
// var b =await UserModel.aggregate().unwind('accounts').exec() //这条是正常
// var b = await UserModel.aggregate().unwind('accounts').match({'accounts.status':'1'}).exec(); //这条匹配到是空的
我要实现的是 查询到accounts.status =1 的所有 子_id 理想是这样子的
// UserModel.aggregate().unwind('accounts').match({'accounts.status':'1'}).sort({'accounts.money':1}).skip(0).limit(10).group({_id:"$_id",accounts:{$push:"$accounts"}}).exec()

@ilaipi 他那个comments 的查找 comments是个数组 然后。。。
themeModel.aggregate()
.project('posts.comments theme_name posts.title posts.post_id')
.unwind('posts')
.unwind('posts.comments')
.match({'posts.comments.to':modelBase._mongoose.Types.ObjectId(user)})
.sort({"posts.comments.time":-1})
.exec().then(function(theme){
fn(null,theme);
});
};
};
