Django Heroku users_customuser 表無法遷移

Question

我有一個 Django 項目，我在本地開發了一段時間。 它在我的本地機器上運行良好，我使用的是自定義用戶設置，因此我的登錄身份驗證只需要電子郵件/密碼，而不是需要電子郵件/用戶名/密碼的默認 Django 用戶表。

我剛剛在 Heroku 上托管了我的項目，並且可以看到網頁 UI 加載得很好。 但是我在單擊任何鏈接時收到 Django 錯誤，並認為它與我嘗試運行時出現的問題有關

heroku run python manage.py migrate

我正在嘗試在 heroku 上運行它來設置數據庫，但是當我這樣做時，我收到一條錯誤消息：

Running python manage.py migrate on ⬢ songsweeper... up, run.1353 (Free)
Operations to perform:
  Apply all migrations: account, admin, auth, contenttypes, playlist, sessions, sites

    return self.cursor.execute(sql, params)

The above exception was the direct cause of the following exception:

我的項目非常大，但為了概述我在哪里定義 customuser，它出現在以下位置：

有沒有人對如何解決此遷移錯誤有任何建議？ 或者它是指示性的還是其他的東西？ 我網站上的“登錄”鏈接導致了一個不同的錯誤，指出“關系“django_site”不存在”，但我認為這與這個失敗的自定義用戶錯誤有關。

我目前使用默認的 sqlite3 db。

我之前遇到過和你類似的問題。 在我看來，我認為這是因為用戶應用程序中的遷移文件。 因此，您必須遷移用戶模型。

$ python manage.py makemigrations users
$ python manage.py migrate

我用上面的方法解決了這個問題。
