我一直在我的本地机器上工作，我最近在一个现有的模型上添加了一些字段。
我今天早上试图在Heroku上推送它并进行迁移，这是我得到的消息：
我的models.py
Class Todo(models.Model):
author = models.ForeignKey(User, on_delete=models.CASCADE,verbose_name="Nom de l'utilisateur")
text = models.CharField(max_length=150, verbose_name="Nom de la Todo")
content = models.TextField(verbose_name="Description supplémentaire",null=True, blank=True)
date_posted = models.DateTimeField(default=timezone.now)
complete = models.BooleanField(default=False)
recurrence = models.BooleanField(default=False)
urgence = models.BooleanField(default=False,verbose_name="Tâche urgente")
def __str__(self):
return self.text
def get_absolute_url(self):
return reverse('dashboard-home')
Todo.recurrence是新领域。

我通常做的是删除我本地计算机上的数据库并再次运行迁移但我真的不能用真实数据做到这一点。
谢谢
你不应该在Heroku上运行makemigrations。在本地执行，提交结果，然后在Heroku上运行迁移。
