Hi Massimo
Yes.
I included the relevant lines in my first post (with writable=False
attribute).
The point was to make an added username field selectively writeable at
the form processing level. I spelt 'writable' incorrectly in one of my
lines. Everything is working fine now.
The username field is required for upcoming enhancements to a web site
with added e-commerce facilities such as an item quantity editable
cart, an order history and a payment history as an account. The key to
getting e-commerce facilities with this level of sophistication
working without headaches is well thought out database table design
and a good framework. Web2py is an excellent framework and has great
database tools, such as database table migration and inbuilt database
administration.
Here is what I am currently using for the username field.
model file before auth.define_tables():
db.Field('username', length=32, label="User Name",
writable=False,),
table.username.requires = [IS_LENGTH(minsize=3,
error_message="Three or more characters required"), IS_ALPHANUMERIC(),
IS_NOT_IN_DB(db, table.username)]
controller file:
def user():
if request.args and request.args[0] in ('register', 'login'):
auth.settings.table_user.username.writable=True
return dict(form=auth())
