Rails控制台：NameError：未初始化的常量

Question

I just added a new model to my app named Collector.

I'm trying to make some data changes using the console on my server:

GsCollector.all.each do |gsc|
  coll = Collector.new
  coll.project_id = gsc.project_id
  coll.kind = 'GsCollector'
  coll.optional = gsc.optional
  coll.included = gsc.included
  coll.save
  gsc.collector_id = coll.id
  gsc.save

  gsc.custom_descriptions.each do |cd|
    cd.collector_id = coll.id
    cd.save
  end

  gsc.order_notes.each do |note|
    note.collector_id = coll.id
    note.save
  end
end

But this fails with:

GsCollector Load (0.3ms)  SELECT `gs_collectors`.* FROM `gs_collectors` 
NameError: uninitialized constant Collector
    from (irb):2:in `block in irb_binding'
    from (irb):1:in `each'
    from (irb):1

What's wrong here? These commands in the console on my dev machine worked fine. I did migrate the database on the server.
