Доброго дня. Просьба сразу не кидаться помидорами. Доки читал, но видать что то недополнял.
К делу. Есть код. В админке, при открытии страницы редактирования или добавления лезет эксепшен.
python: 3.4.3
django 1.10
models.py
class Question(models.Model):
question = models.TextField("Вопрос:")
def __str__(self):
return self.question
class Answers(models.Model):
question = models.ForeignKey(Question, verbose_name="Вопрос: ")
answer = models.CharField("Ответ:", max_length=250)
correctly = models.BooleanField("Правильный ответ", default=False)
def __str__(self):
return self.answer
forms.py
from django import forms
from django.forms.models import BaseModelFormSet
from .models import Answers
class BaseCreateAnswersFormset(BaseModelFormSet):
def clean(self):
"""Checks that no two answers have the same title."""
if any(self.errors):
return
# super(BaseCreateAnswersFormset, self).clean()
currently = False
answers = []
for form in self.forms:
answer = form.cleaned_data['answer']
if answer in answers:
raise forms.ValidationError("Answers must be different.")
if form.cleaned_data['correctly']:
currently = True
answers.append(answer)
if not currently:
raise forms.ValidationError("At least one answer must be correct.")
admin.py
from django.contrib import admin
from django.forms.models import modelformset_factory
from .models import Question, Answers
from .forms import BaseCreateAnswersFormset
class AnswerInline(admin.StackedInline):
model = Answers
extra = 3
max_num = 3
formset = modelformset_factory(model=Answers,
fields="__all__",
formset=BaseCreateAnswersFormset)
class QuestionAdmin(admin.ModelAdmin):
inlines = [AnswerInline]
admin.site.register(Question, QuestionAdmin)
С трейсбека только основное швыряю:
TypeError at /admin/tests/question/add/
__init__() got an unexpected keyword argument 'instance'
Ошибка тут: /home/nxexox/projects/cardio/venv/lib/python3.4/site-packages/django/forms/models.py in __init__, line 563
Вот данные что там есть:
__class__: <class 'django.forms.models.BaseModelFormSet'>
auto_id: 'id_%s'
data: None
defaults:
{'auto_id': 'id_%s',
'data': None,
'files': None,
'instance': <Question: >,
'prefix': 'form'}
files: None
kwargs: {'instance': <Question: >}
prefix: 'form'
queryset: <QuerySet []>
self: <django.forms.formsets.AnswersFormFormSet object at 0x7f5089b6c748>
Если надо полный выложу
