MongoosJS模式非空字符串

Question

我有以下架構定義：

var mongoose = require('mongoose'); 

var CategorySchema = new mongoose.Schema({ 
    name: {type: String, index: { unique: true }}, 
    description: String 
}); 

module.exports = mongoose.model('Category', CategorySchema); 

如何指定name將不接受空字符串。

Answer 1

設置字段作爲需要會做的伎倆，就像如下：

var CategorySchema = new mongoose.Schema({ 
    name: {type: String, required: true, index: { unique: true }}, 
    description: String 
}); 

另一種方法是添加一個驗證的正則表達式，像如下：

var CategorySchema = new mongoose.Schema({ 
    name: {type: String, validate: /\S+/, index: { unique: true }}, 
    description: String 
});
