如何从一个项目获得所有事件？

当我搜索事件时，将其填充，并为事件带来所有引用数据，但是我想通过ID搜索项目，并在项目中获取下面的所有事件，但需要将其查找到获取事件的其他模式

我为此编写的代码是

router.get('/events/:section?', (req, res) => {
  var sectionId = req.params.section
  if (!sectionId) {
    var find = Event.find({}).sort('dateStart')
  } else {
    var find = Event.find({section: sectionId}).sort('dateStart')
  }
  find.populate({
    path: 'section',
    populate: {
      path: 'work',
      model: 'Work',
      populate: {
        path: 'build',
        model: 'Build',
        populate: {
          path: 'project',
          model: 'Project'
        }
      }
    }
  }).exec((err, events) => {
    if (err) {
      res.json({ success: false, message: err })
    } else {
      if (!events) {
        res.json({ success: false, message: 'No se encontraron eventos' })
      } else {
        res.json({ success: true, events: events })
      }
    }
  })
})

这是我的模式

var ProjectSchema = new Schema({
  name: { type: String, required: true, validate: nameValidators },
  createdBy: { type: String },
  created_at: { type: Date, default: Date.now() },
  comments: [
    {
      comment: { type: String, validate: commentValidators },
      commentator: { type: String }
    }
  ]
})

module.exports = mongoose.model('Project', ProjectSchema)

var BuildSchema = new Schema({
  name: { type: String, required: true, validate: nameValidators },
  project: { type: mongoose.Schema.Types.ObjectId, ref: 'Project' },
  createdBy: { type: String },
  created_at: { type: Date, default: Date.now() }
})

module.exports = mongoose.model('Build', BuildSchema)

var WorkSchema = new Schema({
  name: { type: String, required: true, validate: nameValidators },
  build: { type: mongoose.Schema.Types.ObjectId, ref: 'Build' },
  createdBy: { type: String },
  created_at: { type: Date, default: Date.now() }
})

module.exports = mongoose.model('Work', WorkSchema)

var SectionSchema = new Schema({
  name: { type: String, required: true, validate: nameValidators },
  work: { type: mongoose.Schema.Types.ObjectId, ref: 'Work' },
  createdBy: { type: String },
  created_at: { type: Date, default: Date.now() }
})

module.exports = mongoose.model('Section', SectionSchema)

var EventSchema = new Schema({
  name: { type: String, required: true, validate: nameValidators },
  section: { type: mongoose.Schema.Types.ObjectId, ref: 'Section' },
  dateStart: { type: String, required: true },
  dateFinish: { type: String, required: true },
  realStart: { type: String },
  realFinish: { type: String },
  isBegin: { type: Boolean, default: false },
  isCompleted: { type: Boolean, default: false },
  createdBy: { type: String },
  created_at: { type: Date, default: Date.now() },
  comments: [
    {
      comment: { type: String, validate: commentValidators },
      commentator: { type: String }
    }
  ]
})

module.exports = mongoose.model('Event', EventSchema)

如何从一个“项目”中带来所有“事件”？
