Hi,
I'm working with a many-to-many relationship between objects (Owner)
that own a shared resource (SharedResource), where the relationship
has an attribute that indicates the ordering of shared resources for a
particular owner (ordinal). My problem is that I can't seem to get an
order list of shared resources on the owner side.
Here's my setup:
class Owner
...
has n, :owner_shared_resources, :order => [:ordinal]
has n, :shared_resources, :through => :owner_shared_resources
end
class OwnerSharedResource
...
belongs_to :owner, :key => true
belongs_to :shared_resource, :key => true
property :ordinal, Integer
end
class SharedResource
...
has n, :owners, :through => :owner_shared_resources
end
Using `Owner.first.shared_resources` gives an unordered list. I have
tried this:
class Owner
...
has n, :shared_resource_ordinals, OwnerSharedResource, :order =>
[:ordinal]
has n, :shared_resources, :through => :shared_resource_ordinals
end
But to no avail.
I have ended up with:
class Owner
...
has n, :owner_shared_resources, :order => [:ordinal]
def shared_resources
self.owner_shared_resources.map {|x| x.shared_resource}
end
end
Which has obvious drawbacks.
What am I missing here?
