领域-值不能转换为数字 [英] Realm - Value not convertible to a number

问题描述

Hello社区:)我用firebase-> realm实现了许多良好的工作功能.现在，我尝试编辑结构，并且正在浏览最疯狂的错误消息.

Hello community :) I implemented lots of good working functionality with firebase -> realm. Now i tried to edit a structure and I am running through the wildest error messages.

确定什么是正确的:

• Firebase 发送数据
• 数据已已转换(例如，Firebase具有品牌"作为数组->转换为Realm Schema的字符串)
• firebase 更新
时出现错误
• 并非每个firebase内容都具有所有字段(例如，您可以从Realm Schema中看到某些字段是可选:true)

• Firebase sends the data
• Data is Converted (e.g. Firebase has "brands" as array -> is converted to a string for Realm Schema)
• The error appears when firebase updates
• Not every firebase content has all fields (e.g. Like you can see out of Realm Schema some fields are optional: true)

我可能会遇到问题的字段:

• 也许不可能说ReferentList是可选的(或者我实现错误):请参阅领域架构 const ReferentsList

我尝试过的事情

• 在realm.create(领域集)之前进行调试结果:每个数据都以正确的格式出现
• 检查所有输入值是否为int，string，...

希望有人可以在这里为我提供帮助，因为我完全陷于这个问题及其继续进行我的项目的必要性.我想知道:

Hopefully someone can help me here because i got completely stuck with this issue and its necesarry to continue for my project. I want to know:

• 解决方案，为什么或做什么
• 以更好的方式调试领域的可能性 提前感谢您的时间和帮助:)

• The solution why or what to do
• A posibility to debug realm in a better way Thank you in advance for your time and help :)

领域设置

set(obj) {
  realm.write(() => {
      if(obj.referent){
          obj.referent = obj.referent.map(function(id) {
              return {id};
          })
      }
      if (obj.language){
          obj.language = obj.language.map(function(id) {
              return {id};
          })
      }
      realm.create('Events', obj, true);
  });
}

推荐答案

已解决:！ 该问题已通过Firebase上的错误数据得到解决.某些日期对象已正确设置.

Solved:! The issue got solved through wrong data at firebase. Some Date Objects hasent been set correct.

我如何找到解决方案 当我尝试调试代码时，我在周围做了一个try/catch块:

How i got to the solution When i tried to debugg the code i made a try/catch block around:

try{
  realm.create('Events', obj, true);
}catch(error){
  console.log(obj);
  console.log(error);
}

通过该调试，我发现正确的数据是错误的.在显示所有对象之前，然后显示错误.

Through this debug i found the right data wich was wrong. Before it just showed me all objects and afterwards the error.
