Python Pymongo is not updating an existing document

Question

I am trying to update an existing document in MongoDB with the code below:

def insert_data(conn, documents):
    for document in documents:
        new_document = document.split(',')
        result = conn.update_one({ '_id': new_document[0] },
                        { '$set': { "type": new_document[1] } }, upsert=True)
        print(result.raw_result)
    return print('Done')

My print returning:

{'n': 1, 'nModified': 0, 'ok': 1.0, 'updatedExisting': True}
{'n': 1, 'nModified': 0, 'ok': 1.0, 'updatedExisting': True}
{'n': 1, 'nModified': 0, 'ok': 1.0, 'updatedExisting': True}
{'n': 1, 'nModified': 0, 'ok': 1.0, 'updatedExisting': True}
{'n': 1, 'nModified': 0, 'ok': 1.0, 'updatedExisting': True}

But my data on MongoDB still without this property.

Additional info: "TYPE" attribute doesn't exists, this update should create this attribute and set new value.

Am I doing something wrong or should I use other function to do that?

Python 3.7

Pymongo 3.9.0

Thanks!!

Answer 1

I think you have to insert a document as the first parameter into the update_one method.

def insert_data(conn, documents):
    for document in documents:
        new_document = document.split(',')
        result = conn.update_one(document,
                        { '$set': { "type": str(new_document[1]) } })
        print(result.raw_result)
    return print('Done')

Answer 2

def insert_data(conn, documents):
    for document in documents:
        new_document = document.split(', ')
        result = conn.update_one({ '_id': int(new_document[0]) },
                        { '$set': { "type": str(new_document[1]) } })
        print(result.raw_result)
    return print('Done')

just added cast int() and str() before variables, and it works.
