Devise Giving Token Is Invalid Error After Updating Devise Or Devise Invitable

Posted By Weston Ganger

I have upgraded devise in some legacy app and got tripped up by this before.

With the release of Devise 3.1.0 they changed to using hashes of the token.

class RemoveLimitOnInvitationToken < ActiveRecord::Migration
  def up
    change_column :users, :invitation_token, :string, limit: nil
  end

  def down
    change_column :users, :invitation_token, :string, limit: 60
  end
end

It should now have proper tokens in the email link.
