Question

I’ve created a helper which checks a current_user’s role to protect some attributes from being edited by an unauthorised user.

The validation works fine apart from when I’m in the console. Obviously there’s no user but it’s still trying to validate and I get:

 NoMethodError: undefined method `has_role?' for nil:NilClass

How can I bypass this validation or is there a better way to achieve what I’m doing?

Location Model:

  validate :check_archived_status, :on => :update

  def check_archived_status
    unless UserHelper.staff
      if self.archived == false
        if stuff == otherstuff
          do some other stuff
        end
      end
    end    
  end

UserHelper:

def self.staff
  staff = User.current_user.has_role?('Super', 'Admin', 'Tech')
end

Answer 1

Can’t you populate current_user with some random user on your console?
Like this: current_user = User.last, so the validation doesn’t give you any errors.
