问题
I am following the tutorial http://api.mongodb.org/python/current/tutorial.html for bulk inserts. However, I am getting the error that I have listed below. What am I missing? The reviews_array is a json_array
client = MongoClient()
client = MongoClient('localhost', 27017)
db = client.is_proj
db_handle = db.reviews
self.db_handle.insert_many(reviews_array)
The Error:
TypeError: 'Collection' object is not callable. If you meant to call the 'insert_many' method on a 'Collection' object it is failing because no such method exists.
回答1:
In pymongo, before V3.0, you use insert for both single-doc and bulk insert. If you pass a document, it performs a single-insert, and if you pass a different iterable (list, generator), it performs bulk insert.
insert_many() does not exist in pymongo before V3.0.
In pymongo V3.0, they introduced insert_many and insert_one, and the use of the plain insert is deprecated.
