Question

我收到错误：

Exception Value:    
no such table: hello_surname

当我尝试显示访问Surname模型的视图时

在我的models.py

中

class Surname(models.Model):
    created = models.DateTimeField('date created', auto_now_add=True)
    name = models.CharField(max_length=35)

我尝试过运行迁移$ heroku run python manage.py migrate

输出中：

Running python manage.py migrate on ⬢ sleepy-fjord... up, run.7027

Operations to perform:
  Apply all migrations: sessions, auth, hello, contenttypes, admin
Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

然后我运行$ heroku run python manage.py makemigrations

输出：

Running python manage.py makemigrations on ⬢ sleepy-fjord... up, run.8567
Migrations for 'hello':
  0002_surname.py:
    - Create model Surname

当我再次运行top migrate时，它只会提供与我第一次运行它时相同的输出。好像我在这里错过了一步，但凭借输出我似乎无法自己解决。有人知道任何解决方案吗？

您必须运行本地迁移，提交结果，然后在Heroku上运行迁移。

如何使用新表在heroku上迁移本地数据库？
