如何找到一个猫鼬的集合

Question

我使用mongoose和express库调用API来获取mongodb数据。

如果我放弃使用foreach (Control control in tabPage1.Controls.OfType<Button>()) { MessageBox.Show(control.GetType().ToString()); if (control.Name first letters == "indicatorDi") { control.BackColor = Color.LawnGreen; } }

，我使用API​​的代码也可以获取数据

Schema

如果我使用Schema，我试试这个代码我会得到一个空对象

const Driver = require('../models/driver');
const mongoose = require('mongoose');
// If i don't use Schema by using connection can get collection data
const connection = mongoose.connection;

module.exports = {
    gretting (req, res, next) {

        const { theater } = req.query;
        connection.db.collection(theater, (err, collection) => {
            collection.find({}).toArray((err, data) => {
                res.send(data);
            });
        });
    }

这是我的Shecma代码：

module.exports = {
    gretting (req, res, next) {
        // I set the collection name is Tainan
        Driver.find()
            .then(movie => res.send(movie))
            .catch(next);
    }

这是我的主文件app.js使用promise：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const PointSchema = new Schema({
    type: { type: String, default: 'Point'},
    coordinates: { type: [Number], index: '2dsphere'}
});

const MovieSchema = new Schema({
    theater: String,
    phone: String,
    movie: {
        film: {
            moviePhoto: [],
            movieStills: [],
            movieActorPhoto: [],
            movieActorCn: [],
            movieDate: [],
            versionType: [],
            cnName: [],
            movieTime: [],
            movieContent: [],
            movieStyle: [],
            releasedTime: [],
            enName: []
        }
    },
    theaterPhoto: String,
    address: String,
    theaterCn: String,
    geometry: PointSchema
});

const Driver = mongoose.model('Tainan', MovieSchema);

module.exports = Driver;

任何人都知道如何在我的案例中获取我的收藏数据？

此外，如果我想获取指定的字段数据，我该怎么办？

我尝试这段代码，但它仍然是一个空对象

const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const routes = require('./routes/routes');
const app = express();

mongoose.Promise = global.Promise;
if (process.env.NODE_ENV !== 'test') {
    mongoose.connect('mongodb://localhost/movies');
}
app.use(bodyParser.json());
routes(app);
app.use((err, req, res, next) => {
    res.status(422).send({ error: err.message });
});

module.exports = app;

任何帮助将不胜感激。提前谢谢。
