Question

Django-nested-inlines 응용 프로그램을 사용하려고하는데 오류가 발생합니다. 다음은 간단한 코드입니다

MODELS.PY

class Language_Quiz(models.Model): 
    name = models.CharField(max_length=40) 
    language = models.OneToOneField(sfl_models.Language) 


class Question(models.Model): 
    language_quiz = models.ForeignKey(Language_Quiz) 
    text = models.TextField() 

class Answer(models.Model): 
    question = models.ForeignKey(Question,related_name='answers') 
    text = models.TextField() 
    correct = models.BooleanField() 

ADMIN.PY

from django.contrib import admin 
import models 
from nested_inlines.admin import NestedModelAdmin, NestedTabularInline 

class AnswerInline(NestedTabularInline): 
    model = models.Answer 

class QuestionInline(NestedTabularInline): 
    model = models.Question 

class LanguageQuizAdmin(NestedModelAdmin): 
    inlines = [QuestionInline] 



admin.site.register(models.Language_Quiz,LanguageQuizAdmin) 
admin.site.register(models.Answer) 
admin.site.register(models.Question) 

하지만 서버를 실행하거나 마이그레이션을하려고 할 때 오류가 발생합니다. 나는 문제가 어디 있는지 전혀 모른다. 문제가 어디에 있습니까? 카필 Sachdev 및 karthikr은 주석으로서

Answer 1

문제는 호환성이다. 장고 - 중첩 - 인라인에는 Django 1.8 이상에서 작동하는 데 문제가있을 수 있습니다.

내 경우 솔루션은 매우 간단했습니다. pipDjango-nested-inline을 사용하여 다운로드하고 ('인라인'끝에 's'표시 없음) 가져 오기 만 변경하십시오. 코드를 변경할 필요조차 없었습니다.
