In my mongodb I have around 20K records, now From the same mongodb I am importing only 500 records in python and now I need to delete those 500 records which I have imported , is it possible to delete those 500 records using python?
my code for importing 500 records
from pymongo import MongoClient
con = MongoClient(local host, 27017)
db = con.rssfeeds_db
data = pd.DataFrame(list(db.restdata.find().limit(500)))
You would need to use the _id for each record so that you could tell pymongo which records to delete. For example:
from pymongo import MongoClient
con = MongoClient(localhost, 27017)
db = con.rssfeeds_db
// create a list of the records. each one will be a dict.
records = [x for x in db.restdata.find().limit(500)]
// create a list of the 500 ids so we only need to call the db once
record_ids = [record['_id'] for record in records]
//create your dataframe
data = pd.DataFrame(records)
// delete all 500 records at once
db.restdata.delete_many(
{'_id':
{'$in': record_ids}
},
)
