I am a web2py newbie, and I'm sure this is a very basic question, but I
haven't found a post that addresses it exactly.
I am trying to create a form that modifies an existing record. My code,
which is modeled after stuff I saw in the tutorial, looks like:
if idToEdit :
record = db.langResource(idToEdit)
sqlForm = SQLFORM(db.langResource, record) # update existing
else :
sqlForm = SQLFORM(db.langResource) # create new
if sqlForm.process(session=None,
formname="langResource/create").accepted:
response.flash = 'New resource added.'
elif sqlForm.process(session=None,
formname="langResource/modify").accepted:
response.flash = 'Resource modified.'
elif sqlForm.errors:
response.flash = 'Form has errors.'
else:
response.flash = 'Please fill out the form.'
return sqlForm
When idToEdit is set to something, the resulting form is nicely populated
with the values of the existing record. However, when I press Submit, a new
record is added with the changes, and with a new unique ID. The old record
is still there.
I had originally tried to create the HTML by hand, so I could customize it,
and had the same problem, so I thought my HTML was missing something. But
using the SQLFORM directly does the same thing.
I did see this bit in the HTML: <input name="id" type="hidden" value="5" /> -
and wondered if that is the magic bit that makes it know that it is
supposed to update an existing record. But if so it doesn't seem to be
working.
