我在使用mongoose创建复杂查询时遇到了一些困难。
基本上我需要找到有四个条件的所有职业选手：
被击中的人已经排好了。
Pro模型如下所示：
let ProSchema = new Schema({
...
services: [
{
type: Schema.Types.ObjectId,
ref: 'Service'
}
],
zone: [
{
type: Schema.Types.ObjectId,
ref: 'Zone'
}
],
availability: [
{
day: {
type: Number
},
from: {
h: {
type: Number
},
m: {
type: Number
},
min_count: {
type: Number
}
},
to: {
h: {
type: Number
},
m: {
type: Number
}
min_count: {
type: Number
}
}
}
],
unavailability: [
{
from: {
type: Date
},
to: {
type: Date
}
}
],
...
目前这就是我所取得的成就：
const date_start = new Date(req.body.date_start);
const date_finish = new Date(req.body.date_start + (1000 * 60 * 60 * req.body.duration));
Pro.find({
services: req.body.service_id,
zone: req.body.zone_id,
"availability.day": parseInt(date_start.getDay(), 10)
})
这是我发送给服务器以计算在时间范围内可用的Pro（s）的对象：
{
"date_start": 1527423607000,
"duration": 3,
"service_id": "5af0806f178d640aa5e58e4e",
"zone_id": "5afeee28f64d273676d5d3b4"
}
我怎么说，通过moongose搜索在该时间范围内可用的专业人士（从date_start到date_start +持续时间）并且同时不是不可用的？
感谢有人甚至考虑帮助我
编辑：该集合就像这样（专业版）

编辑：经过一天的思考后，我添加了一个min_count给模型，现在查询现在可用于提供：
const date_start = new Date(req.body.date_start);
const date_finish = new Date(req.body.date_start + (1000 * 60 * 60 * req.body.duration));
const min_count_from = (date_start.getHours() * 60) + date_start.getMinutes();
const min_count_to = (date_finish.getHours() * 60) + date_finish.getMinutes();
Pro.find({
services: req.body.service_id,
zone: req.body.zone_id,
"availability.day": parseInt(date_start.getDay(), 10),
$and: [{
"availability.from.min_count": {
$lte: min_count_from
}
},
{
"availability.to.min_count": {
$gte: min_count_to
}
}
],
$and: [{
"unavailability.to": {
$gt: date_start
}
}, {
"unavailability.from": {
$lt: date_finish
}
}]
})
问题在于这件作品无效：
$and: [{
"unavailability.to": {
$gt: date_start
}
}, {
"unavailability.from": {
$lt: date_finish
}
}]
我做错了什么？
