使用JavaScript更改ruby循环变量

Question

Within my controller I have two ways of sorting my database of images:

def index
   @picslist = Pic.order("created_at DESC")

   @picslist2 = Pic.order("price DESC")
end

Within my view I lay them out:

<% @picslist.each do |pic| %>
    PICS IN HERE
<% end %>

I want to alter the @picslist variable to @picslist2 with a JavaScript click event, something like so:

$("#sortbyprice").click(function(event) {

    //replace @picslist with @picslist2

});

Is that the right way of doing it? Either way I'd be grateful if you could recommend a graceful way of doing this!

Many thanks in advance.

Answer 1

making two objects @picslist and @picslist2 is not good idea. Pass the sort_by params when javascript event occured.

def index
   @picslist = Pic.order("#{params[:sort_by]} DESC")  
end

where params[:sort_by] will be "created_at" or "price"

Something like that and use ajax or form submit to update the page.

感谢您的帮助...实际上，我发现最好的方法实际上是对结果进行排序，如此处所述
