    Article.find(1) # => SELECT * from articles WHERE blog_id = 1 AND id = 1

:find takes more keys than written

The documentation says that the :find keywords “may include the :conditions, :joins, :include, :offset, :limit, and :readonly options”. Note that this does not mean that only those options are supported. :sort also works like it should, for example.
