Hi,
I am currently a little confused with trying to manipulate a named
scope that I currently have.
I use this named scope with a table-plus, and it works very nicely,
but I want to trim it down a little.
I have two associated models e.g
Catalogue,
has_many :articles
Article:
belongs_to :catalogue
my named scope looks like this (in Class Article)
:finished_articles, { :conditions => [ :finished => true ] }
This works fine on it's own, but I need to trim it to show only the
most recent finished article per catalogue (based on created_at field)
I have tried to use two named scopes, the other looking like this:
:limited, { :group => "catalogue_id" }
which does only leave one entry per catalogue, but rather than being
the most recent entry it is the first created.
I just want to be able to reverse this order, but I can't seem to
figure out how to do this (I have a default order already set, but
this only seems to affect the scope after it has been rendered..) Also
setting the order does not seem to have an effect on how the instances
are gathered from the database.
