I want the app to raise an error if the value for an array attribute is not an array. Before, when I was using a regular text type for the field, and serializing it with Rails, I was able to make sure the attribute was an array with a custom validation like this: def format_of_admin_email regexp = /.+@.+\..+/i if admin_emails.present? && (!admin_emails.is_a?(Array) || admin_emails.detect { |a| a.match(regexp).nil? }) errors[:base] << "admin_emails must be an array of valid email addresses" end end But now that the field is a Postgres array, it seems like Rails automatically converts the string input into an empty array, so the validation never fails. Here's my migration: class AddAdminEmailsToLocations < ActiveRecord::Migration def change add_column :locations, :admin_emails, :text, array: true end end If I create a Location where admin_emails is a string: Location.create!(admin_emails: "this should fail") it doesn't raise a validation error, and it sets admin_emails to an empty array. Am I doing something wrong or is this a bug in Rails? I also tried checking if the input is an array in a before_validation callback, and added a puts admin_emails.present?, but it returned false, as if it never saw the String input. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
