I''m trying to create custom error messages and in doing so I thought I
could access the validation errors each_key method. I know each_key
isn''t listed as a method for errors object but errors object is a hash
right? When I look at the source of each method
def each
@errors.each_key { |attr| @errors[attr].each { |msg| yield attr, msg }
}
end
each_key is being used but when I access it directly, it barfed with
undefined method error. Anyone knows why? Thanks in advance for your
help.

@errors is an instance variable on the model - I doubt you''re accessing that from the controller... I''m also not clear what''s wrong with @model.errors.each - it gets you exactly the same results as iterating with each_key on the underlying array... --Matt Jones On Aug 12, 8:04 pm, Cali Wildman <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> I''m trying to create custom error messages and in doing so I thought I > could access the validation errors each_key method.

I ended up creating a local hash variable to get the functionality I want. Thanks for your insight. -- Posted via http://www.ruby-forum.com/.
