In my controller I have:
class SerialReachFields(WidgetsList):
serialnumber = Label(label="Serial Number")
reach=SingleSelectField('Reach', options=lambda: [(t.id, t.reach)
for t in Reach.select()])
class SerialReachSchema(validators.Schema):
serialnumber = validators.String(not_empty=True, max=8)
reach = validators.String(not_empty=True, max=45)
class SerialReachForm(TableForm):
fields = SerialReachFields()
validator = SerialReachSchema() # define schema outside of
SerialReachFields
AND
def edit(self, id=None, tg_paginate_limit=25, tg_paginate_no=1,
**kw):
if identity.current.anonymous:
raise redirect("/login", forward_url="%s/
list"%self.rootDir)
try:
record = SerialReach.get(int(id))
except:
flash = "Not valid edit"
RecordReach = record.reach
reachID = Reach.byReach(record.reach)
model_form.fields[1].default=reachID.id
return dict(modelname = self.modelname,
record = record,
form = model_form,
tg_paginate_limit=tg_paginate_limit, tg_paginate_no=tg_paginate_no,
rootDir=self.rootDir)
My App Page shows the way I expect it to the first time it pulls up.
However if i refresh the display for go back and select another record
to edit I get:
Page handler: <bound method serialreach.edit of
<ycwuadispatch.serialreach.controllers.serialreach object at
0x885448c>>

Why am I allowed to set it the first time through by now again? Is
there a way around this?
Thanks,
