Errata

This video uses the html5 widget module in WTForms, which is no longer present. See below the video for a fix!

Widget Fix

Since this video was recorded, Flask-WTF updated and is now using a newer version of the underlying WTForms library. That library has since deprecated the html5 widgets module and moved them into the main widgets module.

When running the code as shown in the video, you may receive this error:

Example 13 Import Error Example 13 Import Error

To resolve this, in MovieForm.py we can simply change the import to be from wtforms.widgets import NumberInput and then remove the html5 in front of each instance where we use NumberInput in the code. See the screenshot below for a corrected version:
