Hey,
I tried py4web from github today on ubuntu 18.04 python 3.6.9.
Using the app scaffold creating a new app: works good
adding new fields in models, works ok: sometimes I get the error "table
persons already exists". I only have that table persons. I need to restart.
Using Py4Web to create an create and update form works good. (Please keep
the form/sqlform replacement around. Its great for protoyping and throw
away apps. *Being able to use Py4Web for prototype, trow away apps plus
serious projects from one framework is great.*
I usually replace the SQLFORM forms after protoyping with proper forms) I
really love the form generator for CRUD.
I tested django-admlte2 and flask-appbuilder today for prototyping in case
Py4Web deprecates SQLFORM, but noting is as good and quick as what you have
done Massimo.
When I add the auth.user to the form the auth request ist not picked up.. I
need to restart.
After the restart the get prompted to login or sign up.
So I sign up.
Desperately tried to disable email validation until I found the link in the
console to validate a user. After I removing a superflous "/" in the URL in
the console registration worked.
After logging in PY4Web crashes however:
