Rails override validation message

Question

I want to see not valid value in validation message.

validates_uniqueness_of :event, :scope => :user_id

Result: \"Title has already has

Answer 1

From the ActiveRecord source code comment:

The values :model, :attribute and :value are always available for interpolation The value :count is available when applicable. Can be used for pluralization.

So you can simply write your message as

validates_uniqueness_of :event, :scope => :user_id, 
                        :message=>"{{value}} is already taken"
