(皮蒙戈)属性错误："插入许多结果"对象没有属性"inserted_count"

Question

我遵循手册https://api.mongodb.com/python/3.4.0/api/pymongo/results.html
和类似问题AttributeError:'；dict'；对象没有属性'；is_active'；(PyMongo And Flask((不适合我的问题(
成功.insert_many或.insert_one后，
.inserted_count不工作

• 功能主要部分I库存

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.")

• 输出：

<pymongo.results.InsertManyResult object at 0x0000017D1D256950>
Traceback (most recent call last):
File "C:UserschuanOneDriveDesktop10.17_connect_mongoD_練習fake02.py", line 54, in <module>
print(x.inserted_count, "documents inserted.")
AttributeError: 'InsertManyResult' object has no attribute 'inserted_count'

print(return_status_str)
print(type(return_status_str))

正如PyMongo文档所描述的，InsertManyResult没有inserted_count属性。您可以改用len(result.inserted_ids)。
