Meteor方法在collection.find()。count()=== 0

标签: javascript mongodb meteor meteor-collections

我有一个集合,我只希望在Collection.find().count() === 0时插入数据。我使用meteor方法进行插入,这样我也可以插入Meteor userId,我的最终目标是在该特定Collection上运行更新函数,我开始工作,但是初始插入的方法一直在运行即使它是if语句中的包装,只表示只在集合为空时才这样做。

所有内容都已发布和订阅,并且还有Financials.allow和deny代码,以及带有ownsDocument的权限文件。如果需要,我会发布所有代码。

同样在控制台中我收到此错误,尽管该方法正在插入数据,即使集合中有文档,我只希望它在空时插入,所以干净安装几乎

感谢您提前提供任何帮助。

尝试将financials.js移动到您的/ server目录中,或将Meteor.methods代码包装在" if(Meteor.isServer)"条件,以确保它在服务器上运行:

if (Meteor.isServer){
 Meteor.methods({
  financialUserId: function(eventAttributes) {



    var user = Meteor.user();
    var financial = _.extend(eventAttributes, {
      userId: user._id
    });
    var financialId = Financials.insert(financial);
    return {
      _id: financialId
    };
  }
 });
}

如果要在客户端上运行该方法,请使用Meteor.userId()获取userId的值。
