Question

我的模式

customer : {
        type: Schema.Types.ObjectId, 
        ref: 'Customer'
    },
    doctor: {
      type: Schema.Types.ObjectId, 
      ref: 'Doctor'
    },
    return_patient  : { 
        type: Boolean, 
        default: false 
    },
    consultation: {
        type: Number,    //1: Phone, 2: Video
        required: true
    }, 
    fee: {
        type: Number
    },
    payment: {
        type: Schema.Types.Mixed
    },
    schedule_date: {
        type: Date
    },
    schedule_time: {
        from: {
           type: String   
        },   
        to: {
           type: String    
        } 
    },

现在我要检查医生的可用性 来自req.query

localhost:9000/api/appointment/doctor-available?doctor=5e83704aadca4064368ff24f&date=2020-04-01&from=5.30&to=6.00

匹配表并查询是否有数据意味着否则医生将不可用 有医生
