If I understand the problem correctly then you don't need that, you
can do has_many data_entries through assessment and in data_entries
the same thing the other way round. That is assuming that all the
data_entries for a reason are those defined for the assessment it
belongs to. Then to get the data_entries for a reason you use
reason.assesment.data_entries. Similarly for the other classes.
