I'm in the following situation. The current url looks like the following: 

`/categories/Art`

And I'm using `name = location.pathname.split('/')[2]` in order to grab the `Art` portion of the URL. Then, I send an AJAX the following path back to the controller: `http://localhost:3000/sort?sortMethod=name&category=name` or date, whichever link is clicked on. 

Now in my controller I can use `sort = params[:category]` to get the string `name`, yet what I'd like to do with this string is sort an array by it. `@categories` is an array of objects and I'd like to call `.sort_by(&:sort)` yet it doesn't recognize the string value of `sort = name`. So now I'd like to convert this string into a proc in order to sort the array. Anyone know how I accomplish this?

Any help is greatly appreciated!
