i have house model has price attribute calculated using instance method. let's price changing due market rates, inflation, etc. need price_today method current price. how can create named scope (or something) filter houses using maximum price , minimum price? i tried doing this, feel it's little hacky... def index @houses = # houses db if not params[:max_price].nil? @houses.keep_if { |h| h.price_today <= params[:max_price].to_f } end if not params[:min_price].nil? @houses.keep_if { |h| h.price_today >= params[:min_price].to_f } end end a named scope (or where clause) faster querying , filtering instantiated objects. however, i'm afraid if price_today not exist in db won't able use them. you can improve code, though. conditions can made simpler, , can use single call keep_if . max = params[:max_price].presence min = params[:min_price].presence if max || min @houses.keep_if |house| = max ?
