Django "XYZ 레이블이있는 응용 프로그램을 찾을 수 없습니다"

Question

나는이 문제에 대한 여러 가지 질문을 모두 해결했지만 아무도 내 문제를 해결하지 못했습니다. 파이썬 2.7이 설치된 Windows 7 가정용 컴퓨터에서 장고 프로젝트의 최신 버전 django 인 virtualenv로 작업하고 있습니다. 이 프로젝트는 Heroku에있을 예정이지만 로컬로도 작동하지 않습니다.

그것도 아주 새로운, 훼손되지 않은 응용 프로그램을 인식하지 못합니다 : manage.py sqlall appname을 실행하려고 할 때

는 기본적으로 항상 다음과 같은 오류 트리를 반환합니다. 예를 들어, manage.py startapp tryagain을 실행 한 다음 manage.py test tryagain과 같은 것을 시도 할 때 여전히 동일한 오류가 발생하므로 'tryagain'을 INSTALLED_APPS에 추가하십시오. 내 settings.py 파일이 정상적인 것과 다른 유일한 방법은 Heroku가, 나는 다음 두 줄을 추가 한 것입니다 :

import dj_database_url 
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')} 

어떤 도움을 크게 감상 할 수있다. 나는 나 자신을 미치게 여기에서 몰고있다.

: 는 또한 내가 manage.py syncdb을 실행할 때, 내가 대신 다음과 같은 오류를 얻을 도움이 될 수 생각 :

또 다른 편집 : , 여기 요청으로 내 models.py입니다.

# models.py 

from django.db import models 

# Create your models here. 

class listing(models.Model): 
    body = models.CharField(max_length=10000) 
    title = models.CharField(max_length=400)

    email = models.EmailField() 
    # imglist as separate model 

    def __str__(self): 
     return self.title

     return self.img_url 

Answer 1

많은 두통 후, 나는 그것을 알아 낸 것입니다. 어떤 이유

, 두 settings.py의가있다 - 전체 프로젝트 디렉토리 craigslist 하나와 하위 디렉토리 craigslist\craigslist 하나, 나는 최상위 settings.py을 편집하고, 나는 하나의 하위 편집되어 있어야합니다. 이유는 모르겠지만 최상위 수준에서 하위 수준 1로 모든 코드를 복사 한 후 갑자기 manage.py sqlall webpage이 작동했습니다.

Answer 2

제 경우에는 제 DJANGO_SETTINGS_MODULE을 수정했지만 내 gunicord 설정 파일 (/ webapps/run/gunicorn_start)에서만 변경했습니다. 그래서 'python mange.py'는 여전히 오래된 settings.pyc 파일을 참조하고있었습니다 ('py'파일은 이미 삭제되었지만 'pyc'는 남아 있습니다 ...).

일단 내가 다음을 수행하면 모든 것이 작동합니다. export DJANGO_SETTINGS_MODULE = ...
