What's the API to access Rails's default can't be blank
error message when validation :presence => true
fails?
I have the model setup like this:
class TextDocument < Document
validate :content_not_blank # 'content' is an attribute
private
def content_not_blank
if content.blank?
errors.add(:content, ....?) # I want to access 'can't be blank'
end
end
end
I18n.t('errors.messages.blank')
should give you what you want.
Assuming you're using standard yaml translations, you can find the file in ActiveModel
To override it you'd drop a file in your config/locales
folder, e.g.:
en:
errors:
messages:
blank: "can't be whatever your custom message"
You can just do it with the default method like this:
validates_presence_of(:content)
This will generate the right message (can't be blank) in the current local (if you setup your config/locales/ ..yml files
if you really want to write your own validator
errors.add(:content, I18n.translate(:blank))
