Thanks for the tips, Crusty!
I took your advice and changed the field
names in my models to be more specific
just in case. I felt a bit uncomfortable with
those field names, as I've had weird reserved
words bite me in the past. I "think" that's
why I was getting that `str object` stuff
in the field value. On top of that I had to
tweak the template snippet. I'd put:
value='values'
...instead of...
value=values
Genshi just quietly blew me off, taking what I gave
it and went on with it's life ignoring what I wanted.
Genchi's a lot like an ex girlfriend of mine. I just
had to learn to ask correctly. Huh, code as a metaphor
for social interaction. Go figure.
Thanks again, Crusty!
In case anyone else runs into a similar problem,
here's a slightly cut-down version of what I have
that works in a canned controller:
##########################################################
import datetime
from sprox.formbase import AddRecordForm
# ddate will be smarter later
ddate = datetime.datetime(2009, 10, 31)
prod = DBSession.query(Product).filter_by(
display_date = ddate).one()
# place_order_form
class PlaceOrder(AddRecordForm):
__model__ = SalesOrder
__hide_fields__ = ['order_id', 'product_id',]
place_order_form = PlaceOrder(DBSession)
class RootController(BaseController):
"""other stuff between here and placeorder"""
#placeorder
@expose('tgdeal.templates.placeorder')
def placeorder(self):
"""Displays the placeorder form using
the product for 'ddate'."""
tmpl_context.place_order_form = place_order_form
values = {
'product_id' : prod.prod_id,
'order_title': prod.prod_title,
'condition' : prod.condition,
'options' : prod.options,
'price' : prod.price,
'shipping' : prod.shipping,
}
return dict(product = prod,
values = values,
page='placeorder')
#place_order_form
@expose()
@validate(
form=place_order_form,
error_handler=placeorder,
)
## placeorder.html template
########################################################
${tmpl_context.place_order_form(
action = 'place_banana_order',
value=values
)}
