#2264: Documentation Error in ToscaWidgets Tutorial

The model columns are described as follows:
{{{
id = Column(Integer, primary_key=True)
title = Column(String(100), nullable=False)
description = Column(Text, nullable=True)
year = Column(Integer, nullable=True)
genre = Column(String(100), nullable=True)
release_date = Column(Date, nullable=True)
}}}
However, every use of {{{genre}}} is store an integer. This results in an
inability to properly build the update form, as the SelectSingleField will
be using an integer, while the options are using a string that happens to
be a number. As a result, the "selected" option will never be present in
the drop down that gets displayed to the user, which means that any
selection done will appear to never take place.
The fix is simple: Define genre as follows:
{{{
genre = Column(Integer, nullable=True)
}}}
After that, update becomes easy again, and things work as expected.
