• 用 Flask 和 SQLAlchemy 实现 "Soft Delete" 模式
  • flask, SQLAlchemy

You can find lots of reasons to never delete records from your database. The Soft Delete pattern is one of the available options to implement deletions without actually deleting the data. It does it by adding an extra column to your database table(s) that keeps track of the deleted state of each of its rows. This sounds straightforward to implement, and strictly speaking it is, but the complications that derive from the use of soft deletes are far from trivial. In this article I will discuss some of these issues and how I avoid them in Flask and SQLAlchemy based applications.
