For some unknown reason my code snippet above didn't show the key line correctly. The important line is the next to last line in the snippet below:
> > @simulation = Simulation.new(sim_hash) > @simulation.user_id = current_user.id > @simulation.save! #need to save to get the id from the database > > buf = Buffer.new(buf_hash) > buf.name='Queue1' > buf.simulation_id = @simulation.id > buf.save!
