在Rails / ActiveRecord列名称中使用问号字符 [英] Using question mark character in Rails/ActiveRecord column name

问题描述

与Ruby在布尔方法（例如 person.is_smart？）中使用问号的惯用法保持一致，我想对Rails：

In keeping with Ruby's idiom of using a question mark in boolean methods (e.g. person.is_smart?), I'd like to do the same for an ActiveRecord field in Rails:

rails generate model Person is_smart?:boolean

我实际上没有运行上面的语句。我假设数据库字段中不能包含问号。 Rails会适当处理吗？

I haven't actually run the above statement. I assume that database fields can't have a question mark in them. Will rails deal with this appropriately? Is the best practice to simply leave question marks off of models?

使用Rails 3.2.8

Using Rails 3.2.8

推荐答案

如果存在名为'smart' smart？ >。

Rails will automatically generate the method smart? if there is a field named 'smart'.
