如何在 mongodb 指南针中使用数组保存 csv 文件？

问题描述

问题图片：

我安装 csv 文件没有任何问题，但它将数组视为字符串。类别必须是数组。

示例代码

  {  "_id":{"$oid":"609196655b92b7164b2cb016"},"body":"test","category":"["Aksiyon Oyunları","Beceri Oyunları"]","date":"1617272388425","gamelink":"ssdsd","imglink":"deneme görseli","status":"published","title":"BUNU YAPIN TREN!","slug":"bunu-yapin-tren!" }

解决方法

    const postSchema = new Schema({
        title: {
            type: String,required: true
        },category: {
            type: [String],required: true
        }
    });

module.exports = new model('posts',postSchema);

架构和此代码与节点 js

mongoose
    .connect(MONGO_URL)
    .then(() => console.log('DB Connected'))
    .catch(err => console.log("Fail to connect mongodb ",err));

    var ops = [];
    post_schema.find({ "category": { "$type": 2} },function(err,arr) {
        arr.forEach(doc => {
            let str = doc.category+``
            str = str.split(',');
            const arr = str.map(e=>e.replace(/"|\[|\]|\\/gm,'').toString())
            ops.push({
              "updateOne": {
                "filter": { "_id": doc._id },"update": { "$set": { "category": arr } }
              }
            });
            if ( ops.length > 0 ) {
                console.log("BULKWRITE")
              post_schema.bulkWrite(ops);
              ops = [];
            }      
          }); 
    })
