Question

I want to check in my app, that input value should be integer and couldn’t be empty or nil.

class Event < ActiveRecord::Base
  validates :event_cost, :presence => { :message => "can't be empty..." }

  validates :event_cost, 
              :numericality => { :only_integer => { :message => "should be only integer" } } 
end

So, if user prints nothing in the field i get message "Event cost is not a number". How can i set my own message instead of that?

Answer 1

Try

class Event < ActiveRecord::Base
  validates :event_cost, :presence => { :message => "can't be empty..." }

  validates :event_cost, 
              :numericality => { :message => "Your own message", :only_integer => true } 
end
