I'm trying to do something relatively simple with a m2m association, but I'm getting an error and I don't know what to make of it. This is my first DB so please bear with me (new to ruby as well). I come from a Core Data background…
Anyway, the pasted code is here: http://pastie.org/1063216 but I'll paste it in the message too: #Syncable require 'model/client.rb' class Syncable include DataMapper::Resource property :id, Serial property :entityName, String property :uniqueIdentifier, String property :timestamp, String has n, :clients, :through => Resource end #Client require 'model/syncable.rb' class Client include DataMapper::Resource property :id, Serial property :clientIdentifier, String has n, :syncables, :through => Resource end # Where I'm using it require 'model/syncable.rb' require 'model/client.rb' require 'model/syncableSub.rb' DataMapper.setup(:default, "sqlite://#{Dir.pwd}/data.sqlite3") DataMapper.finalize DataMapper.auto_upgrade! syncSub = SyncableSubclass.first_or_create(:uniqueIdentifier => changeAttributes["uniqueIdentifier"]) # the join name will be ClientSyncable syncSub.clients << Client.new(:clientIdentifier => h["clientIdentifier"]) #causing error as seen below... syncSub.save # the error: NoMethodError - undefined method `lazy_load' for nil:NilClass: So I'm using a subclass of my "Syncable" class and I can set all the attributes of the sub+super class just fine on the instance (I've edited that part out for the post). But as soon as I try to access or set syncSub.clients I get that error followed by a trace pointing to that line. I'm thinking this should be something very simple but as I am new to this, it doesn't make complete sense to me. I'm using DM 1.0 and all my gems are updated, using Snow Leopard if any of those details matter.
