some tips, add_to_base, save_with_validation, verify

<br />save_with_validation(perform_validation = true) <br /><br />The validation process on save can be skipped by passing false. The regular Base#save method is replaced with this when the validations module is mixed in, which it is by default<br /><br />errors.add_to_base<br />http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/e045ec1dead1ff06<br /><br />The "save" and "valid?" methods call errors.clear<br />before running, which was dumping the errors I had added.<br /><br />Should have thought to put it in the model anyway, it is business<br />logic after all. This works:<br /><br />def validate<br /> if items.empty?<br /> errors.add_to_base("Must select at least one item.")<br /> end<br />end <br /><br /><br />http://api.rubyonrails.org/classes/ActionController/Verification/ClassMethods.html#M000353<br /> verify :params => "post", :session => "post", "flash" => "note",<br /> :only => :update_post,<br /> :add_flash => { "alert" => "Failed to create your message" },<br /> :redirect_to => :category_url<br />
