Associations named using a string cannot be included in a scope
If you defined your association via
class Article belongs_to "category" end
and you try
Article.scoped(:include => :category)
you will get an error message
in `preload_one_association': Association named 'category' was not found; perhaps you misspelled it? (ActiveRecord::ConfigurationError)
Always define your assocations via symbol
class Article belongs_to :category end
