  • best scala idiom for find & return

    - by IttayD
    This is something I encounter frequently, but I don't know the elegant way of doing. I have a collection of Foo objects. Foo has a method bar() that may return null or a Bar object. I want to scan the collection, calling each object's bar() method and stop on the first one returning an actual reference and return that reference from the scan. Obviously: foos.find(_.bar != null).bar does the trick, but calls #bar twice.

  • ActiveRecord find starts with

    - by robintw
    Really simple question - how do I do a search to find all records where the name starts with a certain string in ActiveRecord. I've seen all sorts of bits all over the internet where verbatim LIKE SQL clauses are used - but from what I've heard that isn't the 'correct' way of doing it. Is there a 'proper' Rails way?

  • Opposite of .find()

    - by Ben
    Is there an opposite of .find()? Where $('.myclass').except('#myid'); Would grab all elements with .myclass except the element with #myid. I know I could do $('.myclass[id=myid]') in this example, but seems like it would be helpful in other cases. Thanks

    - by red
    <%= check_box_tag('videos_count')%> If this box is checked, the param will say "videos_count"="1" . In the controller I have this: videos_count = params[:videos_count] @cars = Car.paginate( :page => params[:page], :per_page => 10, :conditions => ["videos_count = ?", videos_count], when the box is checked I see the correct parameter in the server log, but the find returns all of the results instead of results with videos_count = 1.
