如何转换猫鼬模式错误

Question

我想变换全部猫鼬模式错误。

比方说，我有一个UserSchema：

const UserSchema = new mongoose.Schema({ 
    email: { 
    type: String, 
    unique: true, 
    required: [true, 'E-Mail is required'] 
    }, 
    password: { 
    type: String, 
    required: [true, 'Password is required'] 
    } 
} 

如果我想尝试保存而不电子邮件和密码的用户，我会得到如下回应：

{ 
    "errors": { 
    "password": { 
     "message": "Password is required", 
     "name": "ValidatorError", 
     "properties": { 
     "type": "required", 
     "message": "Password is required", 
     "path": "password" 
     }, 
     "kind": "required", 
     "path": "password" 
    }, 
    "email": { 
    // ... 
    } 
    }, 
    "_message": "User validation failed", 
    "name": "ValidationError" 
} 

我想改变这个错误响应全球为我的所有模式，例如到

{ 
    errors: [ 
     { message: "Password is required", path: "password" } 
     // ... 
    ] 
} 

有没有办法将全局变换方法应用于所有模式错误？ （我想避免手动转换每个响应）

Answer 1

var schema = new Schema({ 
    name: { 
    type: String, 
    required: true 
    } 
}); 
var Man= db.model('Man', schema); 

// This man has no name :(
var man = new Man(); 
man.save(function(error) { 
    assert.equal(error.errors['name'].message, 
    'Path `name` is required.'); 

    error = man.validateSync(); 
    assert.equal(error.errors['name'].message, 
    'Path `name` is required.'); 
});
