update_onaccept=StorageList() won't do anything by itself -- that just
enables you to specify a dictionary of lists of update_onaccept functions
(different lists of functions for different tables). So, because the table
name is 'function', you'd do
crud.settings.update_onaccept.function.append(lambda form: ...). But if you
want to add the counter value to the form variables before the database
record is updated, then you'd probably want to use
crud.settings.update_onvalidation, which runs after validation but before DB
update. Even better, though, why not use a computed field:
Field('counter',type='integer',compute=count_functions)
def count_functions(row):
return sum(row.values()[1:9])
