A full example, albeit with SQLObject, but the concept is pretty clear. With web2py, the form.validate would be followed with an explicit data insert. From the looks of the **form_result insert, form.validate returns a list of fields that can be directly inserted. The same format should be able to be used with Storm.
Two of my favorite and most often-used Python packges are formencode and sqlobject.
Using these packages together is done fairly often, but I’ve rarely
seen any documentation describing a full form display, validation, and
insert into a database of new data from said form.
In this example, I’ve tried to wean down the code as much as possible
to get a very concise snippet (only 12 lines of web page Controller
code) that will:
- Display a new form to the user
- Handle form submission
- Validate the form
- Coerce form values into the proper types for the database
- Insert the form data to the database, or
- Display the form with error messages, and maintain their values
nice thing about using formencode, is that 3 of the 6 steps I listed
above are handled by it in a fairly automatic way. Formencode will
check the data given a form schema, coerce the values into the Python
types you ask for, fill in errors should they occur, and maintain the
