I see that #group_by iterates through my list of areas, splitting them into sets according to which ones have the same responsibility. I would like to sort the results of that list. It seems to me that group_by returns an OrderedHash. How to I sort those results prior to passing the |responsibility, areas| pairs? --wpd --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The ordered hash is already sorted by responsibility, so you would
sort each area something like this: (tags removed)
@areas.group_by(&:responsibility).each do |responsibility, areas|
responsibility.name
areas.sort_by{|area| area.name}.each do |area|
...
A style suggestion: make yourself a method in class Area that returns
@areas_grouped_and_sorted. Less code in the view, and reusable.

The problem is that the responsibilities are not already sorted going in. Each area belongs_to a responsibility. I have the list of all of the areas, I want to group them by responsibility, and I want to sort the result by some field within the responsibility. Currently, I have something like: @areas = Area.find(:all) Is there some way to order that ahead of time by areas.responsibility.some_field? Hmmm.... perhaps I''m thinking of this backwards. (It wouldn''t be the first time.) Do I really want to do something like: @responsibilities = Responsibility.find(:all) Hmmmm.... that looks like the right avenue to have taken in the first place.... now... if I could just figure out how to comment out blocks of ERB code, this would be much easier to test and then back out of if it goes awry. --wpd On Fri, Dec 5, 2008 at 7:33 PM, Ed <haywood.ed-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > The ordered hash is already sorted by responsibility, so you would > sort each area something like this: (tags removed) > > @areas.group_by(&:responsibility).each do |responsibility, areas| > responsibility.name > areas.sort_by{|area| area.name}.each do |area| > ... > > A style suggestion: make yourself a method in class Area that returns > @areas_grouped_and_sorted.
