问题描述

const appliedBySchema = new mongoose.Schema({
    _id: { type: mongoose.Schema.Types.ObjectId, ref: "user" },
    timestamp: { type: Date, default: new Date() },
    status: { type: String, default: "Pending" }
});

const positionSchema = new mongoose.Schema({
    job_id: { type: mongoose.Schema.Types.ObjectId,ref:"ad"},
    postedBy: { type: mongoose.Schema.Types.ObjectId,ref:"user" },
    positionName: String,
    reqExp: String,
    appliedBy: [appliedBySchema],
    dept:{type:String , default: false},
    mainRole:{type: String, default: false},
    genderStrictly:{type: String, default:false},
    ageStrictly:{type: String, default:false}
    });

我想更改状态appliedBySchema,请告诉我我必须编写的 mongo 查询以更新状态。现在的模型,但不存在positionSchema的模型。appliedBySchema

解决方案


如果您要更新appliedBySchema,它是文档中的对象数组,您有多种选择(快速的 Google 搜索将证明有用)。但是在我的脑海中,你可以尝试以下

const Position = mongoose.model('positions', positionSchema);
const toUpdate = await Position.findById(idToUse, 'appliedBy');

const appliedBy = toUpdate.appliedBy || [];   // I now have access to all the applied by data
toUpdate.appliedBy = appliedBy.map(entity => {
    // Make manipulations on the entity
    return entity;
});

await appliedBy.save();

这只是为了让它运行。但是那里有更好的选择,例如:
