by default this form would submit to the update (if the record
existed) or create (if it didn't) url for that practice - which
doesn;t sound quite right - the model you are editing
is LPLShortFormApp as I understand it (since the list of areas is a
fixed list). if what you are doing feels like an update/edit/create i
would stick with the default set of actions rather than create a set
action

you're going to have to plough through the params hash. right now it
will be bust since all of your form inputs have the same name (and so
will overwrite each other). The form helpers guide (on
guides.rubyonrails.org) has information on dealing with that sort of
thing.

you're starting to get into the complex forms arena (ie a form that
does not edit/update a single row in the database). one way of going
it would be to have a method on LPLShortFormApp that took as an
argument the info from the params and created the rows in the join
table.
