消息：`模式尚未为模型“用户”注册。\ n` +'使用mongoose.model（name，模式）'，名称：'MissingSchemaError'
我正在尝试为用户身份验证系统创建架构，但始终收到上述错误消息。我用以下代码创建了两个新页面：
Users.js

this.salt = crypto.randomBytes(16).toString('hex');
this.hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
};
//when the setPassword method is called and supplied with a password, the salt and hash will be generated
//for users and added to the model instance - password is never saved anywhere, and not even stored in memory
userSchema.methods.validPassword = function(password){
var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
return this.hash === hash;

我一直在教科书上，格式等正确；我只是不知道错误是从哪里来的。
谢谢您！
回答如下：在用户的底部，您需要声明模型，使用mongoose.model('Users',userSchema);还将其导出，然后与模型进行交互，模式更像是一个声明（详细信息），模型是提供您所需要功能的实现。要求。
您实际上非常接近，您需要将模式参数添加到模型中。
