Ruby on Rails: How to migrate changes after adding validation on models?

I'm new to Ruby on Rails and I'm currently working on models. I have added a new validation to pre created attribute.

This is the validation that I have added.

validates_presence_of :services, :message => 'This field is non-editable'

Do I have to migrate the changes after adding validation? If yes then how?

Any kind of help would be greatly appreciated.

Records already in your database won't be affected. But it you edit a previous record, you won't be able to store it without passing the validation.

You've 3 options:

  • On edit/update, force new field value (default in your case)
  • Create a migration to set default value on the column.
  • Create a migration to update each row with a correct value (not really a good option in my mind)
