Here is my code to delete a bunch of records using pymongo
ids = [] with MongoClient(MONGODB_HOST) as connection: db = connection[MONGODB_NAME] collection = db[MONGODN_COLLECTION] for obj in collection.find({"date": {"$gt": "2012-12-15"}}): ids.append(obj["_id"]) for id in ids: print id collection.remove({"_id":ObjectId(id)}) IS there a better way to delete these records? like delete a whole set of records directly
collection.find({"date": {"$gt": "2012-12-15"}}).delete() or remove() or delete from obj like
obj.delete() or obj.remove() or somehting similar?

To delete one document, we use the delete_one() method. The first parameter of the delete_one() method is a query object defining which document to delete. Note: If the query finds more than one document, only the first occurrence is deleted.
Is PyMongo fork-safe? ¶ PyMongo is not fork-safe. Care must be taken when using instances of MongoClient with fork() .
To delete all documents in a collection, pass an empty document ( {} ). Optional. To limit the deletion to just one document, set to true . Omit to use the default value of false and delete all documents matching the deletion criteria.
You can use the following:
collection.remove({"date": {"$gt": "2012-12-15"}}) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
