The clue is in the error message: Unknown key: :foreing_key
Which is how you have spelt it in the has_many line. It should be
foreign_key of course.

In addition I strongly suggest you stick to the rails conventions for
naming things. So you should not use a name like admitingMd. It
should be belongs_to :admiting_md and has_many admitting_mds (note the
plural for has-many). The key should be admiting_md_id. Are you sure
you don't mean admitting_md?
