in particular, had a table (Catapult) with composite primary key,
where both prop keys are named differently than columns.
this also splits out the route kwargs logic for action urls, because
of another situation where i wanted to use non-primary field as model
key, but it also needed to be stripped of whitespace. this allows for
such an override but in the end i did not pursue that method and just
wound up using default model key anyway..
