Hi all,
I want to provide the most meaningful error message possible when a user enters the wrong data, so I have a series of validation rules like so:
validates_presence_of :name validates_length_of :name, :in => 3..30 validates_format_of :name, :with => /^[a-z]/i, :message => 'begins with a non alphabetical character' validates_format_of :name, :with => /^([a-z][a-z0-9_-]*)$/i, :message => 'contains non alphanumeric characters' validates_uniqueness_of :name
Problem is when one is wrong I'd only like for the first error to be shown, not all of them. I can use an :if => condition type clause but I'm not sure how to do it without duplicating a lot, i.e. (pseudo code)
validates_presence_of :name validates_length_of :name, :if => not name.nil?, :in => 3..30 validates_format_of :name, :with => /^[a-z]/i, :if => not name.nil? and name in 3..30, :message => 'begins with a non alphabetical character'
Any ideas?
