如何转换1为true或0为假时取模型 [英] How to convert 1 to true or 0 to false upon model fetch

问题描述

我有一个设定从MySQL数据库中的JSON响应的模型。该模型数据被设置以真或假到数据库的布尔/ TINYINT字段，它采用1或0

I have a model that is set with a JSON response from a mysql database. The model data is set with true or false into a boolean/tinyint field in the database, which uses 1 or 0.

在我看来，我有一个绑定，对于具有下划线的_.isBoolean一个布尔检查。当然，当我的模型接收到的数据，将其设置为1或0，而不是真或假和_.isBoolean检查失败。

In my view, I have a binding that checks for a boolean with underscore's _.isBoolean. Of course, when my model receives the data, it is set with 1 or 0 instead of true or false and the _.isBoolean check fails.

反正要么正确有从MySQL我的JSON响应是一个true或false值，而不是1或0，preferably，有没有办法让我的模型更新本身在获取（和前视图渲染）的基础上它的1或0财产投真的还是假的？

Is there anyway to either correctly have my JSON response from mysql be a boolean true or false value instead of 1 or 0, or preferably, is there a way to have my model update itself upon fetch (and before the view renders) to cast true or false based on it's 1 or 0 property?

例如。我的模型的数据看起来像 {器isChecked：1} ，当我需要它是 {器isChecked：真正}

e.g. my model's data looks like {"isChecked":"1"} when I need it to be {"isChecked":true}

感谢您大为你可能有任何建议！

Thank you greatly for any suggestions you may have!

推荐答案

所有你需要的是转换字符串到 INT 与 + 并转换的结果与布尔 !! ：

All you need is convert string to int with + and convert the result to boolean with !!:

var response = {"isChecked":"1"};
response.isChecked = !!+response.isChecked

您可以做到这一点的操作在解析方法：

You can do this manipulation in the parse method:

parse : function (response) {
  response.isChecked = !!+response.isChecked;
  return response;
}
