符号在 Rails 项目中必须是唯一的吗？
Must symbol be unique in Rails project?
当我们在 Rails 中使用符号时（例如：用户，：类型...），它们在项目中必须是唯一的吗？例如，我们可以将状态（在状态机中）命名为与属性相同的名称吗？还是有碰撞的风险？
Symbol objects represent names and some strings inside the Ruby interpreter. They are generated using the :name and :"string" literals syntax, and by the various to_sym methods. The same Symbol object will be created for a given name or string for the duration of a program's execution, regardless of the context or meaning of that name.
