One question about that,
I've done taht in order to be OK with rails:
Class Device
has_many :src_links, :class_name => "Link", :foreign_key =>
"src_device_id"
has_many :dst_links, :class_name => "Link", :foreign_key =>
"dst_device_id"
Now I would like to have column 'Link' which would behave like a
normal "has_many" columns (i.e. ability to click and to see the links)
So first I did that:
def links
src_links + dst_links
end
But that doesn't do what I want...
Is there any other way to do that?
Thanks in advance,
