mongoose模式的类型有错误

Question

我正在使用mongoose ODM开发一个使用mongodb的节点应用程序。我在类型引用驻留在不同文件中的模式时收到错误。

我在companyQuery.js文件中有以下代码：

const mongoose = require('mongoose');
const Company = require('./company');
const connectionString = 'mongodb://localhost/company'

mongoose.connect(connectionString);

mongoose.connection.on('connected', () => {
    console.log('Mongoose connected');
})
mongoose.connection.on('disconnected', () => {
    console.log('Mongoose is disconnected');
})
mongoose.connection.on('error', (err) => {
    console.log(err, 'mongoose error');
})

它引用了文件company.js：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const companySchema = new Schema({
        name: {
    type: String, 
    required: true
},
founded: Date,
employees: Number,
active: true;
products: [String],
ceo: {
    name: String,
    age: Number
}
});
const Company = mongoose.model('Company', companySchema);
module.exports = Company;

这是我得到的错误：

/Users/ashley/salty-sardines/mongoose-3/node_modules/mongoose/lib/schema.js:696
    throw new TypeError('Undefined type ' + name + ' at ' + path +
    ^

TypeError: Undefined type 'undefined' at 'active'
  Did you try nesting Schemas? You can only nest using refs or arrays.

    at Module.load (internal/modules/cjs/loader.js:599:32)

该问题在我的存储库中的三台不同的机器上复制，并且我已经重复编写了四次代码，结果相同。如果我删除const Company = require('./company');并将信息合并到一张纸上，我可以让它工作。任何帮助将不胜感激，因为我已阅读所有其他关于此类错误的帖子，没有人提供我的解决方案。

可能你只需要替换它：

active: true,

有了这个：

active: {
  type: Boolean,
  default: true,
}
