Hi:
I am a fresh in Turbogear.
After finish the 20-min wiki, I try to add a upload function to the
wiki. well, I don't understand how the data could be sent to kid. I
have search previous discuss about this issu.get the solution as
following, But I don't know how can I get the data in kid template.
what should I add in kid.
I tried to add like this:<p py:content="upload_form()">upload</p>, <p>$
{upload_form}</p>,but it seems not work.
Could you explain the machanism of the data transform between kid and
control.py
In this case, what should I write in the template.
Thank you
