Windows: Throw new mongoose.Error.MissingSchemaError(name);

Question

Mongod在windows终端正常运行，但Nodemon显示以下错误:

C:Usersenzocdesktopapinode_modulesmongooselibindex.js:520
throw new mongoose.Error.MissingSchemaError(name);
^
MissingSchemaError: Schema hasn't been registered for model "Usuario".
Use mongoose.model(name, schema)

Answer 1

您要么没有为usario定义一个模式，要么没有导入它以便在.model()函数中使用。你可以试试类似的

const Usario = mongoose.model('User', new Schema({ name: String }));

有关更多示例和函数文档，您可以访问https://mongoosejs.com/docs/api/model.html#model_Model或https://mongoosejs.com/docs/api/schema.html#schema_Schema

Answer 2

每当我们遇到这种问题时，总是记得检查堆栈跟踪!

> at Object.<anonymous>
> (C:UsersenzocdesktopapicontrollersUsuarioController.js:2:26)

如果你检查这一行，你会明白在UsuarioController行号2，常用模型/模式已初始化。但是在您的系统中没有具有尊敬的名称的文件。请创建那个文件。

要了解更多详细信息，请检查创建mongoose模式。

希望你的问题解决了!
