When we create GridFS object empty collection fs.chunks is generated. May be it isn't right to do this in this step?
import pymongo from gridfs import GridFS conn = pymongo.Connection() conn.drop_database("gridfs-test") print("Collections: " + str(conn["gridfs-test"].collection_names())) # Collections: [] g = GridFS(conn["gridfs-test"], "fs") print("Collections: " + str(conn["gridfs-test"].collection_names())) # Collections: [u'system.indexes', u'fs.chunks']
