How to Fix: Fully custom validation error message with Rails

To display a fully custom validation error message in Rails, you can use the `:message` option with the `validates_presence_of` method and specify the field name using the `:attribute_name` option.

💡 Solution

• Use the `:attribute_name` option with `validates_presence_of`: `validates_presence_of :song_rep_xyz, attribute_name: :song_title, message: 'can't be empty'

  Example:

  1. Step 1: Update your validation code to use the `:attribute_name` option

  By doing this, you can display a custom error message that is specific to each field.

  Example Code:

  validates_presence_of :song_rep_xyz, attribute_name: :song_title, message: 'can't be empty'

  🎯 Final Words

  With this solution, you can display fully custom validation error messages in Rails without modifying the field names in your database.
