Странные деформировать/поведение дуршлаг «строковые индексы должны быть целыми числами»

Question

Так у меня есть следующий рабочий код, который я использую в течение последних нескольких месяцев

class UserSchema(colander.MappingSchema): 
    dob = colander.SchemaNode(
      colander.Date(), 
      title='Date of birth:') 

if 'submit' in request.POST: 

    controls = request.POST.items() 
    try: 
     appstruct = myform.validate(controls) 
    except ValidationFailure, e: 
     return {'form':e.render(), 'values': False} 

Теперь это базовая дата выбора, как показано на рисунке здесь:

Но вдруг, когда с помощью этого виджета я получаю ошибку:

По меньшей мере, форма управления формой дампа регистрируется и публикуется здесь. Постарайтесь быть более подробным & с примерами кода и не смешивать код схемы коллаборатора и код представления пирамиды.

if 'submit' in request.POST: 

    controls = request.POST.items() 
    try: 
     appstruct = myform.validate(controls) 
    except ValidationFailure, e: 
     log.debug('form validation fails for %r' % controls) 
     return {'form':e.render(), 'values': False}
