The mongodb_ecto package wishes to switch its underlying driver to this one, since it has better support for current MongoDB versions. However, a series of changes are required to support the adapter.
Some BSON encoders and a missing generic update function were added for the adapter. Plus, a small option fix for the
do_log
function inmongo.ex
.Most notably, the find-then-modify command functions
find_one_and_update
andfind_one_and_replace
now return appropriateFindAndModifyResult
structs that contain additional write information otherwise neglected, which the adapter requires. This is also consistent with the other existing mutative command functions that already return respective result structs.
