If it helps at all, here's the controller function that creates and
processes the form:
def dupAndEdit():
"""Create and process a form to insert a new record, pre-populated
with field values copied from an existing record."""
tablename = request.args[0]
rowid = request.args[1]
orderby = request.vars['orderby'] or 'id'
restrictor = request.vars['restrictor'] or None
formname = '%s/%s/dup' % (tablename, rowid)
src = db(db[tablename].id == rowid).select().first()
form = SQLFORM(db[tablename], separator='', showid=True, formstyle='ul')
for v in db[tablename].fields:
# on opening populate duplicate values
form.vars[v] = src[v] if v != 'id' and v in src else None
# FIXME: ajaxselect field values have to be added manually
if db[tablename].fields[1] in request.vars.keys(): # on submit add
ajaxselect values
extras = [f for f in db[tablename].fields
if f not in form.vars.keys()]
for e in extras:
form.vars[e] = request.vars[e] if e in request.vars.keys() \
else ''
del form.vars['id']
print 'form vars ========================================='
pprint(form.vars)
if form.process(formname=formname).accepted:
db.commit()
print 'accepted form ================================='
the_url = makeurl(tablename, orderby, restrictor)
response.js = "web2py_component('%s', " \
"'listpane');" % the_url
response.flash = 'New record successfully created.'
elif form.errors:
print 'listandedit form errors:', [e for e in form.errors]
print 'listandedit form vars:', form.vars
response.flash = 'Sorry, there was an error processing '\
'the form. The new record has not been created.'
else:
pass
return dict(form=form)
