我完全按照https://devcenter.heroku.com/articles/django
指定了heroku但是当我正在运行heroku run python manage.py syncdb
它的说法ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.
这就是我的settings.py文件的样子。我尝试了所有似乎没有帮助的解决方案

Sultan和Joe都是正确的,如果你把它们放在一起并稍微挖一点就可以了,我只想更清楚地说明一点,这对我有帮助。 Heroku网站上的这些instructions解释了如何设置它,包括Sultan提到的内容,将此部分添加到settings.py:
# Parse database configuration from $DATABASE_URL
import dj_database_url
DATABASES['default'] = dj_database_url.config()
# Honor the 'X-Forwarded-Proto' header for request.is_secure()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
# Allow all host headers
ALLOWED_HOSTS = ['*']
# Static asset configuration
import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = 'staticfiles'
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)
然后,(和那些说明中没有提到的内容)在您的Heroku帐户中转到您的数据库部分并选择您要使用的数据库。转到“连接设置”(两个方向相反的小箭头)并选择Django选项。该代码看起来应该像Joe提到的那样:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'your_db_name',
'HOST': 'your_host',
'PORT': '5432',
'USER': 'your_db_user_name',
'PASSWORD': 'your_password',
}
}
将其粘贴到settings.py文件的底部并同步您的数据库。

您是否尝试过https://devcenter.heroku.com/articles/django#django-settings文档中的内容?
import dj_database_url
DATABASES['default'] = dj_database_url.config()
它说
Django设置
接下来,配置Heroku环境的应用程序,包括 Heroku的Postgres数据库。 dj-database-url模块将解析 DATABASE_URL环境变量的值并将它们转换为 Django可以理解的东西。
确保'dj-database-url'在您的需求文件中,然后添加 在settings.py文件的底部:
<强> settings.py 强>
# Parse database configuration from $DATABASE_URL
import dj_database_url
DATABASES['default'] = dj_database_url.config()
# Honor the 'X-Forwarded-Proto' header for request.is_secure()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
# Allow all host headers
ALLOWED_HOSTS = ['*']

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

STATICFILES_DIRS = (

)

您正在定义DATABASES = {'default': {... }}
两次。
解决方案:
如果您使用heroku为您的数据库提供服务,请使用此
import dj_database_url
DATABASES['default'] = dj_database_url.config()
如果您尝试连接到外部数据库服务器,请注释上面的两行并使用此
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
'NAME': '', # Or path to database file if using sqlite3.
# The following settings are not used with sqlite3:
'USER': '',
'PASSWORD': '',
'HOST': '', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
'PORT': '', # Set to empty string for default.
}
}
答案 3 :(得分:0)
您尚未定义任何数据库信息 您的DATABASES部分应如下所示:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'your_db_name',
'USER': 'your_db_user_name',
'PASSWORD': 'your_password',
'HOST': 'ec2-23-21-133-106.compute-1.amazonaws.com', # Or something like this
'PORT': '5432',
}
}
