I can not understand form.accepts(). I think it's because my intuitive understanding of web2py is wrong. Here's how I think it works:
A simple controller function ( index() say) can return a string in which
case web2py will simply serve it up as a web page.
The same function can return a dictionary, in whcih case web2py takes the
dictionary, finds a corresponding view file, merges them together using
token replacement and serves the resulting string as a web page.
So, when I see a controller method looking something like:
def show():
form = SQLFORM(...)
if form.accepts(request.vars, session):
...
I'm reading it as: create a form, and if the user's input (request.vars) is
valid then process the input. My problem is that the form has not been
served up to the user, so how can we have the user's input?
Obviously I am confused. Any help would be appreciated.
