Selecting a subset of a table with DRY
Hello,
I have table called ''listings.'' There are a certain combination of
properties which make a listing viewable (e.g., it is confirmed, has
been authorized, hasn''t expired, etc.). Each listing has one and only
one category.
I want to be able to do things like Listing.find_viewable(...) and
Category.find(...).viewable_listings, but I see no way to do this
