使用 Rails 的完全自定义验证错误消息 [英] Fully custom validation error message with Rails
问题描述
Using Rails I'm trying to get an error message like "The song field can't be empty" on save. Doing the following:
validates_presence_of :song_rep_xyz, :message => "can't be empty"
... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly. How can I change the title of the field itself ? I could change the actual name of the field in the database, but I have multiple "song" fields and I do need to have specific field names.
I don't want to hack around rails' validation process and I feel there should be a way of fixing that.
Now, the accepted way to set the humanized names and custom error messages is to use locales.
# config/locales/en.yml
en:
activerecord:
attributes:
user:
email: "E-mail address"
errors:
models:
user:
attributes:
email:
blank: "is required"
Now the humanized name and the presence validation message for the "email" attribute have been changed.
Validation messages can be set for a specific model+attribute, model, attribute, or globally.
