Hi,
i was looking through the docs and couldn''t find a good clean solution
for ordering a partial with an :order clause.
say i was iterating over categories and thier corresponding
sub-categories (regular belongs to) and wanted to order the
subcategories according to a certain column;
<% for category in @categories %>
<% render: partial => ''sublist'', :collection =>
category.subcategories, :order => ''position'' %> #
position is a
column in my subcategories table
<% end %>
this isn''t really working; is there a different way to do this in the
view or do i have to access this through my controller?
thanks,
jeff

<% @categories.each do |category| %> <%= render :partial => ''sublist'', :collection => category.subcategories.sort_by(&:position) %> <% end %> That should do it. -Jonathan.

i looked up in rubycentral.com (couldn''t buy the rails book just yet)
and i found a arr.sort function that fit my needs exactly... i ended up
doing
for subcat in category.subcategories.sort {|subcat1, subcat2|
subcat1.position <=> subcat2.position}
and i got a perfect order in the subcat output list.
thanks for your help...

You could specify the order explicitly for the partial <%= render :partial=>''sublist'', :collection => category.sucategories.find(:all, :order => ''position'') %> Or include the order in the has_many deleration has_many :subcategories, :order => ''position'' Either one should work. Johnathans approach should work also.
