[Flask] Data validation

Ok, I got how to do data validation using wtforms, as well as preventing
CSRF.

Now, how is the procedure I need to do if the data fails SERVER validation?

For example, it passes 'form.validate()" but testing within that 'if'
reveals bad data. I want to keep the existing data in the form, but reject
the form because
some value was not correct, and set a error message and re display the form
...

As always thanks.
