Class Method Details

.sync(server, recordings, full_sync = false) ⇒ Object

Syncs the recordings in the db with the array of recordings in ‘recordings’, as received from BigBlueButtonApi#get_recordings. Will add new recordings that are not in the db yet and update the ones that already are (matching by ‘recordid’). Will NOT delete recordings from the db if they are not in the array but instead mark them as unavailable. ‘server’ is the BigbluebuttonServer object from which the recordings were fetched.

TODO: catch exceptions on creating/updating recordings
