ruby-on-rails - rails : Naming conventions for attributes

Question

我用这条线创建了一个模型

rails g scaffold contact firstname:string lastname:string email:string

但是属性应该是这样的

first_name:string 

反而？

Answer 1

惯例不是一成不变的，但遵循它们是好的。
是的，广泛传播的属性名称约定是 snake case .

Snake case:

punctuation is removed and spaces are replaced by single underscores. Normally the letters share the same case (either UPPER_CASE_EMBEDDED_UNDERSCORE or lower_case_embedded_underscore) but the case can be mixed.
