Using the form wizard, user inputs values into fields and upon completion
of form is redirected to sqlform.grid page, where the uploaded file can be
viewed, this all works. The problem is when I try to view the database I
get this error:
* def formatter(self,value): return '%.2f' % valueTypeError: float
argument required, not str*
This was not a problem until I implemented the form wizard, I can't figure
out what is causing it.
*Models:*from decimal import *
class IS_MYDECIMAL(IS_DECIMAL_IN_RANGE):
def formatter(self,value): return '%.2f' % value
db.define_table('tablecosts',
Field('yourname', 'string', requires=IS_NOT_EMPTY(), label='Your
name:'),
Field('thedate', 'date', requires=IS_DATE(format='%m-%d-%Y',
error_message=T('Enter date in the format: mm-dd-yyyy')), label='Report
date:'),
Field('num1', requires=IS_MYDECIMAL(None,None),
label='first:'),
Field('num2', requires=IS_MYDECIMAL(None,None),
label='second:'),
Field('num3', requires=IS_MYDECIMAL(None,None),
label='third:'),
Field('num4', requires=IS_MYDECIMAL(None,None),
label='fourth:'),
##there are a lot more fields but this is the gist of it, to keep the post
short
Field('costs_file', 'upload', compute=costs_calc),
Field('created_by', 'reference auth_user',
default=auth.user_id, readable=False, writable=False))
*Controller:*
@auth.requires_login()
def tablecosts():
STEPS = {0: ('yourname', 'thedate'), # fields for 1st page
1: ('num1', 'num2', 'num3'), # fields for 2nd page
2: ('num4'), #fields for 3rd
##this goes on for a few pages with more fields
6: URL('costslist')} # url when wizard completed
step = int(request.args(0) or 0)
if not step in STEPS: redirect(URL(args=0))
fields = STEPS[step]
print "Fields: " + str(fields) + " Step " + str(step)
if step==0:
session.tablecosts = {}
if isinstance(fields,tuple):
form = SQLFORM.factory(*[f for f in db.tablecosts if f.name in
fields])
if form.accepts(request,session):
session.tablecosts.update(form.vars)
redirect(URL(args=step+1))
else:
db.tablecosts.insert(**session.tablecosts)
session.flash = T('form completed')
redirect(fields)
return dict(form=form,step=step)
def done():
return dict(message="End of form", back=A("New form",
_href=URL("costslist")))
@auth.requires_login()
def costslist():
grid = SQLFORM.grid(db.tablecosts.created_by == auth.user_id,
fields=[db.tablecosts.yourname,
db.tablecosts.thedate, db.tablecosts.costs_file])
return locals()
If the user enters 10, it becomes 10.00 and if they enter 5.00 it stays
5.00. When I open the uploaded file, it works and shows this. However,
since implementing form wizard it does not allow me to view db because of
it, I am confused because it worked fine before.
