Retrieve data from a collection(mongo),modify the returned object and insert it into another mongo collection

Question

{
        "name" : "XYZ",
        "phone" : 12345,
        "emp_id" : 9999,
        "sal" : 5000
}

I want to add data on this record and store it into another database. I have tried this:

db=connection.testing

results=db.test.find({"name":"XYZ"})

for i in results:

    i.append('dept':'Marketing')
    db.test.insert_one(i) 

(please ignore the insertion being done on the same connection)

Error:    i.append('dept':'Marketing')

                         ^
SyntaxError: invalid syntax

How to add data in the dictionary form or JSON form?

Answer 1

由于在您的示例中i似乎是字典，因此您很可能需要类似i.update({'dept': 'Marketing'})或i['dept']='Marketing' ，以引入新的键/值对
