This fixes
ids_writer
so that it can handle a composite primary key. Using a CPK model associated with a non-CPK model was working correctly (which I added a test for). Using a CPK model associated with another CPK model was not working correctly. It now takes it into account to write the correct ids.While working on
ids_reader
I found thatpluck
is not working for CPK because it's passing an array of attributes and that's not supported bydisallow_raw_sql!
. I chose to callflatten
inpluck
but not conditionally because this seems like it could be a problem elsewhere as well. This fixes pluck by CPK overall and fixes a test in the calculations test file.cc/ @nvasilevski @paarthmadan
