def reify(assoc, model, options, transaction_id)
  # Load the collection of through-models. For example, if `model` is a
  # Chapter, having many Paragraphs through Sections, then
  # `through_collection` will contain Sections.
  through_collection = model.send(assoc.options[:through])

  # Now, given the collection of "through" models (e.g. sections), load
  # the collection of "target" models (e.g. paragraphs)
  collection = collection(through_collection, assoc, options, transaction_id)

  # Finally, assign the `collection` of "target" models, e.g. to
  # `model.paragraphs`.
  model.send(assoc.name).proxy_association.target = collection
