问题描述 #

ProductTag、User、UserProduct这三个模块无法将数据填充到SQLite数据库中，目前无法定位具体原因，初步怀疑可能是缩进错误、缺失导入或语法错误导致。

程序运行输出 #

首次运行输出：

Product 1 created: True
Product 2 created: True
Product 3 created: True
Product 4 created: True

Tag Electronics updated: True
Tag Apple updated: True
Tag Headphones updated: True
Tag Laptops updated: True

Test database created and populated successfully.

betsy.db

Test database created and populated successfully.

betsy.db

再次运行输出：

The creation of products ('Product 1', 'Product 2', 'Product 3', and 'Product 4') appears to be successful.

The update of tags ('Electronics', 'Apple', 'Headphones', and 'Laptops') in the database also show successful.
