I think what [email protected] pointed out is most poignant, you can accomplish
what you are trying to accomplish with this (ruby 2 syntax)
scope :low_level, -> { where(:level => 1) }
The you reference this scope as Article.low_level
as you get your hands dirty with AR scopes, read & understand what "lazy
evaluation" is in the query lifecycle.
here's a good post about it:
