Django遷移使用FileField與動態上載路徑失敗

我正嘗試使用django FileFiled的動態上載路徑。這是我的模型：，Django遷移使用FileField與動態上載路徑失敗

Traceback (most recent call last):

AttributeError: module 'models' has no attribute 'AutoField'

如果不知道它爲什麼發生在我使用的是靜態的上傳路徑是：

def use_assignment_path(instance, filename): 
    return 'assignment/%s/%s' % (instance.name, filename) 


class Assignment(models.Model): 
    admin = models.ForeignKey(Admin) 
    name = models.CharField(max_length=50, unique=True) 
    lang = models.CharField(max_length=5, default='c', choices=(('c', 'c'), ('java', 'java'))) 
    pointsRecommended = models.IntegerField() 
    file0 = models.FileField(upload_to=use_assignment_path) 
    file1 = models.FileField(upload_to=use_assignment_path, default='', blank=True)

當我嘗試遷移模型我得到這個錯誤工作得很好。

我已經閱讀了幾個類似的問題，但沒有什麼幫助，直到知道。

坦克你！

看起來好像你的應用程序名稱models與django.db.models衝突。嘗試重命名您的應用，刪除初始遷移，然後重新運行makemigrations和migrate。

謝謝你的工作！ – Max

刪除「/media/sf_Websites/HM/trunk/assignments/models/migrations/0001_initial.py」文件，然後再試一次
