After reading this appetizer Rolling with Ruby on Ralis last week, I immediately started downloading all stuff and building the part one application. Without much knowledge of Ruby I'm afraid.
As could be expected, it ended with a undefined method in list.rhtml, after a new recipe was added. At that moment, I did no further reading (stupid me), but tried to repair it by myself, adding ... if defined? to it. That did not work, because defined? always returns nil, and defined? recipe.category always returns method. I added ... unless recipe.category.nil? instead, which did the trick and looks more elegant.
But it leaves me puzzled: recipe.category and, what kind of Ruby things are they?
