I am new to Django and Heroku. I just deployed my project following the heroku documents. Part of settings.py is:

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()

part of 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()

in registerBasicInfo.py: 

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()

after I push to heroku & syncdb, the following error occurred:

Any idea to solve it? I suffered it for days, appreciate your help!

将您的代码更新为：

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md5用于密码；而是使用set_password.

问题解决了。我没有为我的应用程序正确创建模型表，具体来说，我没有正确地将我的应用程序放入 settings.py 的 INSTALLED_APPS 中。非常基本和愚蠢的问题...
