如何获取除主键之外的表列的值

For getting the value of the primary key of the selected row, we can use record.get('id') in extjs. How to get the values of other columns (Say, if I have a column named name or t_id). In my case when I alert record.get('id') it gives the exact value whereas alerting record.get('t_id') shows undefined.

为了获取所选行的主键值，我们可以在extjs中使用record.get（'id'）。如何获取其他列的值（例如，如果我有一个名为name或t_id的列）。在我的情况下，当我提醒record.get（'id'）时，它给出了确切的值，而警告record.get（'t_id'）显示未定义。

Thanks.

谢谢。

Update:

更新：

I am getting the result for record.get('name'). Only the foreign key t_id is not working.

我得到了record.get（'name'）的结果。只有外键t_id不起作用。

You need to check certain thing @ejo.

你需要检查某些东西@ejo。

1. As @Daemon said you need to check whether you had defined 't_id' in your store feilds or in model. 
2. Second, you need to check whether you are sending the 't_id' value from backend.
3. third, if you use grid.getview option, check whether that t_id has been mapped to grid.

The most important one, please post your code, so that we can able to find the problem.

Yeah! The foreign keys in grid are always missing in my experience. Please try defining a hidden field for that foreign key(not tested yet):

是啊！在我的经验中，网格中的外键总是缺失。请尝试为该外键定义一个隐藏字段（尚未测试）：

column :t_id do |c|
  c.hidden = true
end
