I’ve recently needed to insert lots of objects into the Mongo collection. The only problem was that some of the objects would have an ‘_id’ key pre-set and would conflict with existing objects in the database.
PyMongo inser_many operation doesn’t support it out of the box, so here is a work-around using bulk api:
bulk = collection.initialize_unordered_bulk_op() # or ordered
objects_to_insert = (prepare generator for objects that need to be saved)
for one in objects_to_insert:
except BulkWriteError as exc:
# exc.details available for more information
pass # do something here
