Question

我是meanjs的新手。现在我陷入了如何使用mongoose操纵从mongodb查询的数据。这是我的情况：

模型架构是这样的：

var AdminUserSchema = new Schema({
firstName: {
    type: String,
    trim: true,
    default: '',
    validate: [validateLocalStrategyProperty, 'Please fill in your first name']
},
lastName: {
    type: String,
    trim: true,
    default: '',
    validate: [validateLocalStrategyProperty, 'Please fill in your last name']
},
displayName: {
    type: String,
    trim: true
},
email: {
    type: String,
    trim: true,
    default: '',
    validate: [validateLocalStrategyProperty, 'Please fill in your email'],
    match: [/.+\@.+\..+/, 'Please fill a valid email address']
},
username: {
    type: String,
    unique: 'Username already exists',
    required: 'Please fill in a username',
    trim: true
},
password: {
    type: String,
    default: '',
    validate: [validateLocalStrategyPassword, 'Password should be longer']
},
salt: {
    type: String
},
provider: {
    type: String,
    required: 'Provider is required'
},
providerData: {},
additionalProvidersData: {},
roles: {
    type: [{
        type: String,
        enum: ['user', 'admin']
    }],
    default: ['admin']
},
updated: {
    type: Date
},
created: {
    type: Date,
    default: Date.now
},
/* For reset password */
resetPasswordToken: {
    type: String
},
resetPasswordExpires: {
    type: Date
},
enabled: {
    type: Boolean,
    default: true
}

}）;

当我尝试获取数据并使用以下代码进行操作时：

var AdminUser = mongoose.model('AdminUser');
AdminUser.find().exec(function(err, users) {
    if(err) {
        return res.status(400).send({
            message: errorHandler.getErrorMessage(err)
        });
    } else {

            users[1].password = undefined;
            users[1].salt = undefined;
            var created = moment(users[1].created).format('YYYY-MM-DD');
            users[1].created = created;

            console.log(created);
            console.log(users[1].created);
            console.log(users[1]);
    }
});

结果显示如下，它不起作用。

{
    _id: 55233e0c488bd50b1eafe558,
    salt: undefined,
    displayName: 'testtest',
    provider: 'local',
    username: 'test',
    __v: 0,
    enabled: true,
    created: TueApr07201512: 00: 00GMT+1200(NZST),
    roles: [
    'admin'
    ],
    password: undefined,
    email: 'test@test.com',
    lastName: 'test',
    firstName: 'test'
}

我试图像这样操纵： users[1]['created'] = created;

或使用set功能： users[1].set('created', created);

两个都失败了。请伸出手。

任何帮助都将不胜感激。

修改

您可以在架构中定义getter。

created: { type: Date, default: Date.now, get: function(date) { // return a formatted string instead of the Date object return moment(date).format('YYYY-MM-DD'); } }

您是说要从数据库中获取AdminUser模型，修改它，然后将其保存回数据库？
