(Pymongo) AttributeError: 'InsertManyResult' object has no attribute 'inserted

I follow the manual https://api.mongodb.com/python/3.4.0/api/pymongo/results.html
and similar problem AttributeError: 'dict' object has no attribute 'is_active' (PyMongo And Flask) (not fit mine issue)
after successfully .insert_many or .insert_one,
the .inserted_count not working

function main part I stock

if one_or_many_bool == True:
    x = mycol.insert_many(insert_values_json)
else:
    x = mycol.insert_one(insert_values_json)
return x

print(x)
print(x.inserted_count, "documents insert.")

output:

<pymongo.results.InsertManyResult object at 0x0000017D1D256950>
Traceback (most recent call last):

CodePudding user response：

As the PyMongo doc described, InsertManyResult doesn't has the inserted_count attrbute. You can use len(result.inserted_ids) instead.
