MongoosJS Schema 非空字符串

Question

我有下面的架构定义：

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将不接受空字符串。

Answer 1

根据需要设置字段将起作用，如下所示：

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

另一种选择是添加一个验证正则表达式，如下所示：

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