Documentation inconsistency

[rianradeck]

The tutorial file flaskr/blog.py does not check if the body is empty, but the body must be not null according to flaskr/schema.sql.

The following methods in flaskr/blog.py and their respective views are affected by this:

• create
• update

To replicate, create a blog post with an empty body.

The expected behavior shouldn't let the user create the post with an empty body.

I vision two possible solutions:

• Add verification for an empty body in necessary parts of the code.
• Let the body be NULL in the flaskr/schema.sql.

Environment: Ubuntu 20.04.6 LTS

• Python version: 3.8.10
• Flask version: 2.3.2

The empty string is not the same as NULL. The value must not be null. It may be empty.
