在Rails 4中，有没有一种方法可以覆盖to_s方法以正确显示url字段？

Question

My Profile model has a portfolio_url field.

In error messages (as well as other places), it's displayed as 'Portfolio Url'.

Is there a way to customize this in one place (my guess is overriding a to_s method) so it's displayed as Portfolio URL ?

Answer 1

There is no need to override a method to change the label of an ActiveRecord attribute. Just add the name you want to use to your translation file:

# in config/locales/en.yml
en:
  activerecord:
    attributes:
      profile:
        portfolio_url: "Portfolio URL"
