I have a model based in a view:
class Item < ActiveRecord::Base
set_primary_key :id # I guess that this shouldn’t be necessary
end
When I do:
a = Item.first
a.any_attribute = “xxx”
a.save
it throws the error:

`save’
(yes, I’m using IronRuby 1.1.3 - it is great!!!
Digging deeper in the code I’m finding that it has to do with
Item.arel_table not having @primary_key set.
At that point I’m Stuck.
Thank you in advance for your help.
