Hello,
I'm having trouble selecting only some specific resources from 2 tables. That's my code: categories = %w{cat1 cat2 cat3} categories.each { |category| cat = CharacterAttributeCategory.find_by_name category @character_attribute_types += CharacterAttributeType.find_all_by_character_attribute_category_id cat.id }
I tried << before but that doesn't work as well. I get following error: NoMethodError in CharactersController#new
You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.+
Any hints?
