Thanks Massimo --
I don't know what my problem was other than the view was confusing
me.
Your code works perfectly on my end as well (Python 2.5.2 on Mac
here). The view still reports request.var.import_csv as a
"FieldStorage" object, but the form.accepts() processing gets
triggered properly and the file is read.
I'm a happy camper and this pattern is going into my website! I'll
have a link to it here soon so everyone can take a look. It's not
beautiful to anyone but me so far, but it makes pretty extensive use
of web2py's DAL power. The users of the site (high school swim
coaches) are ecstatic to have it.
Regards,
-- Joe B.
