Node.JS - Mongoose不会将数据保存到MongoDB并且Object不能正确获取信息？

Question

所以首先，我检查了相关的question，但由于我没有使用相同的中间件，我认为这对我没有帮助。我有一个常规表单，并且它可以顺利通过req.body，并且可以打印所有表单值。然而问题是当我尝试创建一个新对象时，因为当我打印它时，它没有我分配的正确字段......？其次，当我尝试保存它时，当我通过终端检查时，它不会显示在Db中。我已经成功地运行了Mongod并连接到了正确的Db和集合，所以我很困惑。任何帮助将不胜感激！

添加第二个参数是你的集合名称

var MuseumObject = new mongoose.Schema({ 
     accessionNum: String, 
     maker: {String, default: ''}, 
     manufacturer: {String, default: ''}, 
     title: String, 
     date: {String, default: ''}, 
     medium: {String, default: ''}, 
     dimensions: {String, default: ''}, 
     marks: {String, default: ''}, 
     description: {String, default: ''}, 
     pic: {String, default: ''} 
    }, 
    {collection:"your_collection_name"});
