Hi,
I have been using Web2py for couple years now, but have not been able to
find a decent solution to this issue.
When creating a new web app I am constantly updating new fields to a
database table after I already have data there. When I add a new field, I
want it to have a default value for
Here's the link to the video from pyvideo.org:

but I think Massimo's videos are better for actually learning the framework

Juslin, I've done it manually like in your example. Yes it's long, but gives
full control on every field. I also define number of rows for each text box and
have a placeholder text. Also classes and other parameters (e.g. Default
values) are easier too define in view than in controller, so that

I got the scheduled background script working in PA. The script is started
in web2py environment with -S app and -M -R parameters. The script

I've been reading and trying to figure out the best way to implement

PythonAnywhere. Is it
Looks promising. I can test this next week. I will implement an email

I don't think you can use a web based application without a server.
However, the local server is already there without additional installation,

Hi guys,
I thought of using pythonanywhere for the next level of development, so
deployed my code there. I had been using sqlite as a test environment, and
wanted to move to the mysql database that pythonanywhere provides.
I created a new mysql database and then switched the DAL connection to:
rm.custom.widget.FIELD['_class'] = 'text myclass'}

You can redirect to any page you wish from a function. This way you don't
have to create a page for the function and can decide what is the page you
want to call.
example:
def no_page():
redirect(URL('index'))
This is beneficial, if you want to have a function which handles the link

After learning Python and web2py deeper, I've restructured my web2py

Hi,
If I understood correctly, you could use 'session' to save the list, so you

E.g. session.serials = [] and then session.serials.append(x)
