validations and :message

rubyonrails-talk

hey all,

nice that we can override the error message when a certain type of validation fails by using :message. i've used this to help the user so they can better understand why the app is rejecting their input (or lack of input).. problem: the damn message comes up, but it prepends the message with the fieldname .humanize'd !! I do not want that. anybody know how to make it do what i want (just the message)??

thanks in advance and happy railsing (railling?) to all!

I think, you can do this, but not with using validation helpers. I use the following code (in model/ *.rb file), for example: ..... protected def validate    errors.add({}, "The price should be positive.") unless self.price.nil? || self.price > 0.0 end .....

write your own version of error_messages_for() . Just have a look at the source of this Helper Method in the API, it's very simple ... instead of

Object.errors.fullmessages

just use

Object.errors.each {|attr, msg| ...}

to loop though the errors and use only your defined messages without the prepended Attribute name.
