我正在使用该教程来部署Django.[http://devcenter.heroku.com/articles/django]在我做了一个git push heroku master后,没有web进程.

在日志中它看起来如下.

我将repo推送到heroku master后,我收到此错误([Errno 2]没有这样的文件或目录).这是我的日志.

2012-04-17T18:24:53+00:00 app[web.1]: python: can't open file '/test/project/manage.py': [Errno 2]     No such file or directory

我的学生模型中有以下内容.我想跟踪给每个学生的每个点的日期.这个想法是这样我不仅可以看到每个学生有多少分,而且还可以看到每个学分的日期.在未来,我希望看到学生积分的趋势.我该怎么办呢？我应该在另一个班级使用外键吗？我是新手,所以感谢阅读.

class Student(models.Model): 
  CLASS_CHOICES = ( 
    (u'Yoga','Yoga'), 
    (u'Spanish', 'Spanish'), 
    (u'French', 'French'), 
    (u'Dance', 'Dance'), 
  ) 
  name = models.CharField(max_length=30) 
  points = models.IntegerField(max_length=4) 
  classname = models.CharField("Class Name",max_length=20, choices=CLASS_CHOICES) 

我已在本地服务器上使用south成功同步了我的数据库.我在Heroku中使用南方时遇到了问题.我跑的时候

git add app/migrations/*

git commit -m 'adding new migrations'

heroku run python manage.py migrate app

我收到了一个DatabaseError.关系字段已存在.

任何想法为什么这不起作用？此外,每次我的某个模型更改时,是否需要在本地和生产环境中运行迁移？谢谢阅读.
