maybe something like this would work :
if idToEdit :
record = db(db.langResource.id==idToEdit)
sqlForm = SQLFORM(db.langResource, record) # update existing
else :
sqlForm = SQLFORM(db.langResource) # create new
if sqlForm.process().accepted:
response.flash = 'New resource added.'
elif sqlForm.process().accepted:
response.flash = 'Resource modified.'
elif sqlForm.errors:
response.flash = 'Form has errors.'
else:
response.flash = 'Please fill out the form.'
return sqlForm
