风帆 Model.create

Question

我正在按照一本书自学 Sails。

书中的代码应该是：

Video.create(foundVideos).exec(function(err, videoRecordsCreated){
            if(err){
              console.log('err', err);

              return cb(err);
            }
            console.log('videoRecordsCreated', videoRecordsCreated);
          });

然而运行 sails lift 我收到以下错误：

err { UsageError: Invalid new record. Details: Got an array, but expected new record to be provided as a dictionary (plain JavaScript object). Array usage is no longer supported as of Sails v1.0 / Waterline 0.13. Instead, please explicitly call .createEach().

如何解决这个问题？看起来代码应该在以前版本的 .create 中工作，但现在不再支持数组使用....

如何重写此代码以使用最新的 Sails 版本？

Answer 1

Waterline 的 create 方法要求参数为对象。

根据您遇到的错误，foundVideos 似乎是一个对象数组。在这种情况下，您需要使用需要对象数组的 createEach 。像这样：

  Video.createEach(foundVideos).fetch().exec(function(err, videoRecordsCreated){
    if(err){
      console.log('err', err);

      return cb(err);
    }
    console.log('videoRecordsCreated', videoRecordsCreated);
  }));
