все! Я пытаюсь передать значение в функцию init и заполнить одно из моих полей данными из другой модели. Я жестко закодировал значение, чтобы получить правильные данные в своем поле.
Я хочу знать, как передать начальные значения в функцию init? Я нашел много решений, но они не работают для меня.
Я пытался передать первичный ключ в начальный func:
forms.py
class ObservationPartsForm(forms.ModelForm):
def __init__(self, pk=None, *args, **kwargs):
super(ObservationPartsForm, self).__init__(*args, **kwargs)
primary = kwargs.get('pk')
print('Get pk',primary) #Get pk None
instance = kwargs.get("instance")
meteostation = MeteoStation.objects.get(id=pk)
if instance == None:
meteoparam = forms.ModelChoiceField(
queryset=meteostation.meteo_parametrs.select_related().filter(is_active=True),
label='Метеопараметр',
)
self.fields['meteoparam'] = meteoparam
else:
value_selected = forms.ChoiceField(label='Значение для выбора')
self.fields['value_selected'] = value_selected
#print(instance)
class Meta():
model = ObservationParts
fields = ('meteoparam',
'value_digit',
'value_selected',
'author_parts',
'who_updated')
ObservationEntireFormset = inlineformset_factory(ObservationEntire, ObservationParts,
form=ObservationPartsForm, extra=1,
)
views.py
class ObservePartsCreateView(CreateView):
template_name = 'dairy/test.html'
model = ObservationParts
#form_class = ObservationPartsForm
success_message = 'Метеопараметры добавлены к наблюдению.'
formset = None
def get_form(self, form_class=None, **kwargs):
pk_ = self.kwargs.get("pk")
print(pk_)
form = ObservationPartsForm(pk=pk_)
return form
def get_initial(self, **kwargs):
initial = super(ObservePartsCreateView, self).get_initial()
initial['value_selected'] = ObserveDate.objects.all()
return initial
def get(self, request, *args, **kwargs):
pk_ = kwargs.get("pk")
observe_entire = ObservationEntire.objects.get(pk=pk_)
self.formset = ObservationEntireFormset(instance=observe_entire)
return super(ObservePartsCreateView, self).get(request, *args, **kwargs)
def get_context_data(self, **kwargs):
context = super(ObservePartsCreateView, self).get_context_data(**kwargs)
context['formset'] = self.formset
return context
def post(self, request, *args, **kwargs):
pk_ = self.kwargs.get("pk")
observe_entire = ObservationEntire.objects.get(pk=pk_)
self.formset = ObservationEntireFormset(request.POST, instance=observe_entire)
if self.formset.is_valid():
self.formset.save()
return redirect('test', pk=observe_entire.id)
else:
return super(ObservePartsCreateView, self).get(request, *args, **kwargs)
def get_form_kwargs(self, **kwargs):
pk_ = self.kwargs.get("pk")
kwargs = super(ObservePartsCreateView, self).get_form_kwargs()
kwargs['primary'] = pk_
return kwargs
Когда я передаю какие-либо значения в функцию init , у меня появляется ошибка:
Значение исключения:
'ObservationPartsForm'У объекта нет атрибута' name '
Traceback, если я пытаюсь передать значение, например,
ObservationEntireFormset = inlineformset_factory(ObservationEntire, ObservationParts, form=ObservationPartsForm(pk=1), extra=1,)
Traceback:
Exception in thread django-main-thread:
