@areas.group_by(&:responsibility).each do |responsibility, areas|
<%=h [responsibility.name](http://responsibility.name) %>
<% areas.each do |area| %> ...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
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
<% if false -%> commented out <% end -%>
Works for me when I don't have time to think up anything else...
