I must be doing something very wrong. The field I get back does not
seem to have any of the components it should have.
Here is my controlller:
def import_csv():
from gluon.sqlhtml import form_factory
form=form_factory(SQLField('import_csv','upload'))
if form.accepts(request.vars,session):
request.flash='Received: %s'%request.vars.import_csv
#do more processing here
return dict(form=form)
And here is the view:
{{extend 'layout.html'}}
<h1>This is the meets/import_csv.html template</h1>
{{=form}}
{{=BEAUTIFY(request.vars.import_csv.filename if
request.vars.import_csv else '')}}
The if clause above was to see if the field contained anything under
"import_csv". It did not.
I was trying to follow the information in the manual on page 177 but
there seemed to be missing information (like the input field itself).
I am currently using version 1.56.3. I plan to update as soon as the
current swim meet is over and I can take the site down for awhile as I
work on it.
