validations only work for current locale, not for translations added using set_translations

[khelben]

when you define a 'validates_presence_of :something' on a model, this is only checked for translations in the current locale but not for any other translations you set using 'set_translations':

test "validates_presence_of using set_translations" do
Validatee.class_eval { validates_presence_of :string }
assert !Validatee.new.valid?
assert Validatee.new(:string => 'foo').valid?
### The following fails
assert_nothing_raised do
Validatee.new(:string => 'bar').set_translations(:fr => { :string => '' })
end
end

One solution is to set the validations on the translation class itself:

test "" do
Validatee.translation_class.class_eval do
validates_presence_of :string
end

I18n.locale = :en
validatee = Validatee.new(:string => "a string")
assert validatee.valid?
validatee.set_translations(:nl => {:string => ''}) rescue nil # we need to recsue as set_translations uses update_attributes!
assert !validatee.valid? ### this works

end
