无法迁移挂起的迁移

Question

我将我的django项目部署到heroku，并尝试迁移我的挂起的迁移，但在运行迁移命令时出现问题。首先我进行迁移，然后我开始迁移，但它显示

您的模型具有尚未在迁移中反映的更改，因此将不会应用。运行'manage.py makemigrations‘进行新的迁移，然后重新运行

  (postjust)erkans-MacBook-Air:postjust erkan$ heroku run python  manage.py makemigrations
        /Users/erkan/.rvm/gems/ruby-2.1.1/gems/heroku-3.7.5/lib/heroku/helpers.rb:93: warning: Insecure world writable dir /Users/erkan/Dev`enter code here`/Python in PATH, mode 040777
        Running `python manage.py makemigrations` attached to terminal... up, run.8854
        Migrations for 'pages':
          0002_auto_20150405_2137.py:
            - Alter field content on page
            - Alter field date on page
        Migrations for 'blog':
          0006_auto_20150405_2137.py:
            - Remove field categories from page
            - Delete model Page
            - Alter field date on blogcategory
            - Alter field date on blogpost


    (postjust)erkans-MacBook-Air:postjust erkan$ heroku run python  manage.py migrate
    /Users/erkan/.rvm/gems/ruby-2.1.1/gems/heroku-3.7.5/lib/heroku/helpers.rb:93: warning: Insecure world writable dir /Users/erkan/Dev/Python in PATH, mode 040777
    Running `python manage.py migrate` attached to terminal... up, run.9864
    Operations to perform:
      Synchronize unmigrated apps: django_extensions, tinymce
      Apply all migrations: sessions, contenttypes, pages, admin, auth, blog
    Synchronizing apps without migrations:
      Creating tables...
      Installing custom SQL...
      Installing indexes...
    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.

我找不到问题所在。

你不应该远程运行makemigrations。heroku run会为每个命令创建一个新的dyno，因此您创建的迁移会立即丢失。

在本地运行makemigrations命令，将它们提交到git，然后推送到heroku，它们将自动运行。
