Example 6-4

Seems db.session.commit() statement missed.

Note from the Author or Editor:
You are correct. This has been corrected in the GitHub repository for this project, and will also be corrected when the book is reprinted. Thanks!

Prior to Example 9-4

In the paragraph before example 9-4, you say "instead a class method can be added". However, Example 9-4 shows a static method rather than a class method.

Note from the Author or Editor:
This report is correct. The reference to "class method" should be changed to "static method". I will update this in the book's source files myself so that it is fixed for the next reprint.
