I can’t seem to find anything to explain how I might be able to order a
list according to the number of occurrences of an item in a has_many
relationship, so maybe someone could help me learn how…
To illustrate, imagine I have the following situation:
I have one table with details for a number of people, and one table of
items. Each item belongs to one person and each person can have may
In my view I have something like this:
<% for person in @people %>
I can get the list to order by the id/name etc. of the people, but I
really want to order it by the number of items belonging to each person,
something like so:
@people = Person.find(:all, :order => ‘person.items.count desc’)
except that this brings up an ‘unknown column’ error.
Any ideas for getting around this?
