Use custom I18n messages in a model validation

I would like to show custom translated error messages (based on the
locale in the URL) for my validations. I have to following:

validates :phone, :format => { :with => /^(0{2}|+)/, :message =>
I18n.t(‘validation.need_international_format’) }

First, is this the correct way to add custom validation messages or am
I doing it wrong?

Now, if I understand this correctly the model is only loaded once, at
boot time. So I think the message is also only evaluated once, again,
at boot time. If my default locale is English it means the English
message is used. Now, if I switch to French without restarting the
application Rails will use the French message without reevaluating the
model?! How is this done?

Thanks!

Use :message => :need_international_format and e.g.

en:
activerecord:
errors:
models:
customer:
need_international_format: “must be in the international
format”

See http://guides.rubyonrails.org/i18n.html for more info.

Great, this works much better! Thanks Henrik.
