问题描述

我正在尝试创建Django项目/网站和教程的投票"部分( $ python manage.py进行迁移民意测验.这给了我错误->找不到应用程序"polls".是在INSTALLED_APPS中吗?我从这里做什么?添加民意调查后，我同步了数据库，但仍然无法正常工作.

I am trying to create the 'polls' part of my Django project/website and the tutorial (https://docs.djangoproject.com/en/1.8/intro/tutorial01/) says that before we 'activate' the models we have to include 'polls' in the INSTALLED_APPS library in settings.py. I did that, then I do--> $ python manage.py make migrations polls. This gives me the error--> App 'polls' could not be found. is it in INSTALLED_APPS?. What do I do from here?! I synced my database after I added polls, still doesn't work.

推荐答案

在settings.py中，您会发现INSTALLED_APPS，并且必须如下所示添加民意调查.

In settings.py you will find INSTALLED_APPS and you must add the polls as shown below.

    INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'polls'
]
