Question

我有以下Django应用程序结构：

sarpedon33
   rango
       migrations
   sarpedon33
   media
   static
   templates

我收到此评论＆＃34; App＆＃39; rango＆＃39;无法找到。是INSTALLED_APPS吗？＆＃34;当我尝试为rango应用程序制作时。

settings.py是这样的：

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

STATIC_PATH = os.path.join(BASE_DIR,'static')

STATIC_URL = '/static/' # You may find this is already defined as such.

STATICFILES_DIRS = (STATIC_PATH,)
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media') # Absolute path to the media directory

SECRET_KEY = '****************************************************'

DEBUG = True

ALLOWED_HOSTS = []


# Application definition

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
)

Answer 1

将rango应用添加到INSTALLED_APPS：

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rango', # <--- HERE ----
)

Answer 2

如果有人来到这里是因为他们看到了这个错误，即使他们确实拥有 INSTALLED_APPS中列出的应用，就像我使用旧代码一样。

不要使用project_dir.app_name或任何类似的结构。只写应用程序名称，例如：

错误：

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'directory.my_app_name',
)

这是正确的：

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'my_app_name',
)

TangowithDjango - makemigrations - App＆＃39; rango＆＃39;无法找到。它在INSTALLED_APPS中吗？
