私は自分のアプリを開発していたので、モデルにslugfieldを追加しました。その後、通常通りmakemigrations
に進み、大きな赤い壁のエラーが現れました。OperationalError:そのようなテーブルはありません
Traceback (most recent call last):

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

私は追加したフィールドを削除しようとしましたが、使用しませんでした。私は、stackoverflowで提案されているものは、ほとんどすべて行ってきました。
また、githubにプロジェクトを追加するのを忘れてしまったため、元のデータベースファイルもありません。

"プロジェクトをgithubに追加するのも忘れていましたが、元のデータベースファイルもありません。空のテーブルでマイグレーションを実行しているようです。そうですか? – e4c5
@ e4c5ええ、データベース内には何もありません(Pycharmのデータベースシステムでチェックされています)。おそらくすべてを残して、私がstackoverflowで見つけた解決策を試してはいけないはずです。 –
