Ich versuche einige Python-Dateien von Django 1.3 auf Django 1.11 zu aktualisieren. In der views.py Datei habe ich eine Methode mit der folgenden ZeileUmzug von Django 1.3 nach Django 1.11 object_list
return object_list(request, queryset=results['flips'], extra_context=context, **kwargs)
ich, dass Object_List gelesen habe jetzt veraltet ist und statt dass ich Listview verwenden, um von django.views.generic.list und verwende Klassenansicht.
Ich habe mit dieser versucht:
Django 1.3
views.py
def flow(request, **kwargs):
agent = 'default'
lang = request.LANGUAGE_CODE.lower()
cache_key = '%s%s%s' % (request.build_absolute_uri(), request.user.id, lang)
results = cache.get(cache_key)
if results is None:
results = {}
flips = pushitem.visibles.visibles().by_lang(lang=lang)
sort = request.GET.get('sort', '')
if sort == 'popular':
flips = flips.order_by('-votes_total')
else:
flips = flips.order_by('-timestamp')
scope = request.GET.get('scope', '')
if scope:
today = datetime.now()
if scope == 'day':
flips = flips.filter(timestamp__year=today.year, timestamp__month=today.month, timestamp__day=today.day)
if scope == 'month':
flips = flips.filter(timestamp__year=today.year, timestamp__month=today.month)
if scope == 'year':
flips = flips.filter(timestamp__year=today.year)
#Todo use UserProfile instead of User for people and add a searchfield to UserProfile (faster)
query = request.GET.get('q', '')
if query:
people = User.objects.filter(Q(username__contains=query))
people |= User.objects.filter(Q(first_name__contains=query))
people |= User.objects.filter(Q(last_name__contains=query))
flips = flips.filter(Q(searchfield__contains=query))
topics = Tag.objects.filter(Q(name__contains=unidecode(query.lower())))
results['people'] = people
results['topics'] = topics
results['flips'] = flips
cache.set(cache_key, results)
context = {
'title': _('Flipter.com, Ask everything!'),
'description': _('The world\'s largest community of opinions, made with awesome polls.')
}
if results.has_key('people'):
context['people'] = results['people']
if results.has_key('topics'):
context['topics'] = results['topics']
return object_list(request, queryset=results['flips'], extra_context=context, **kwargs)

Aber wenn ich versuche, in die Seite zu gelangen, bin ich getti ng die folgenden Fehler:
'FlipView' object has no attribute 'kwargs'
oder
'FlipView' object has no attribute 'status_code'
