If there's no typo here you're not passing a callable but the result
of the call to makeOptions. You'll need a closure for that to work:
def makeOptions(results, labelColumn, seperatorColumn=None,
AddNull=False,MultiLang=False):
def get_options():
values = []
for result in results:
try:
label = getattr(result,labelColumn)
except:
if MultiLang == True:
label = 'LabelNotFound'
else:
for lang in list
(myprojectweb.model.languages.select()):
label[lang.languageCode] = 'Error'
if MultiLang == False:
values.append((result.id,label
[myprojectweb.utils.getActiveLanguage()]))
else:
values.append((result.id, label))
if AddNull == True:
values.insert(0,('-1',' '))
return values
return get_options
