form.instance.category = get_object_or_404(Subcategory, title=self.request.POST['category'])

In jQuery's case, $ is just an alias for jQuery

Object.keys(obj).map(function (key) { return obj[key]; });

$arr = [
        ["рр","ыы","ыаы",20,"ыаы",2],
        ["ыпв","ып","вп",9,"впрр",4],
        [ "вр","вр","вр",30,"вр",5],
        ["врар","ароа","аоао",50,"ааоао",12]
    ];


    for($i = 0; $i < count($arr); $i++)
    {
        for($j = 0; $j < count($arr[$i]); $j++)
        {
        }
    }
