Is it possible to override has_many’s :order attribute at run-time? e.g.
something like:
<% for category in @site.categories(:order=>‘name’) %>
…
<% for category in @site.categories(:order=>‘rank’) %>
…
thanks

<% for category in @site.categories.find(:all, :order=>‘name’) %>

Check the development log, and you shall have the answer directly.
I’m quite sure the answer is no.
You could put this loop into a partial, render it to a string in
the controller, and reference the string in the view twice.

Oops, did not notice the orders were different!
So…make that “The answer is no.” 
You could grab the categories in the controller, then use a Ruby
sort in the view…
controller:
@categories = @site.categories
view:
<% for category in @categories.sort { |a,b| a.rank <=> b.name } %>
<% for category in @categories.sort { |a,b| a.rank <=> b.rank } %>
