Django無法在heroku上保存postgresql實例

我是Django和Heroku的新手。我剛剛在heroku文檔之後部署了我的項目。 settings.py的部分是：Django無法在heroku上保存postgresql實例

try: 
    userInfo.objects.exists() 
except DatabaseError: 
    user = userInfo() 
else: 
    user = userInfo.objects.filter(email = email) 

    if user: 
     # check if the account is fully registered 

     if user.gymID: 
      return HttpResponse(content = 'user exist', status = 503) 

user.email = email 
pwmd5 = hashlib.md5(password) 
user.password = pwmd5.hexdigest() 

user.save()

我推到Heroku的&執行syncdb後，出現以下錯誤：models.py

class userInfo(models.Model): 
    """The member information 
    """ 

    email = models.EmailField() 
    password = models.TextField() 
    account = models.CharField() 
    gender = models.CharField() 
    iconID = models.IntegerField() 
    gymID = models.IntegerField() 
    friendsNumber = models.IntegerField() 
    signature = models.CharField() 
    weibo = models.BooleanField()

在registerBasicInfo.py

的

DATABASES = { 
    'default': { 
    'ENGINE': 'django.db.backends.postgresql_psycopg2', 
    'NAME': 'dfuldndi54p56q', 
    'HOST': 'ec2-54-227-251-13.compute-1.amazonaws.com', 
    'PORT': 5432, 
    'USER': 'pmotmgcaijwixy', 
    'PASSWORD': 'Wp0Gjf66JEC4mRKkvKrF22ptnj' 
    } 
} 

# Parse database configuration from $DATABASE_URL 
import dj_database_url 
DATABASES['default'] = dj_database_url.config()

部分發生：

任何想法解決它？我忍受了好幾天，感謝你的幫助！

問題解決。我沒有正確創建我的應用程序的模型表，具體來說，我沒有正確地將我的應用程序放入settings.py中的INSTALLED_APPS。非常基本和愚蠢的問題...

更新您的代碼如下：

user = userInfo.objects.get_or_create(email=email) 
if user.gymID: 
    return HttpResponse(content = 'user exist', status = 503) 

pwmd5 = hashlib.md5(password) 
user.password = pwmd5.hexdigest() 
user.save()

另外，不要使用md5的密碼;改爲使用set_password。

嘗試與user = userInfo.objects.get_or_create（email = email），但仍然得到相同的錯誤 – Tate
