Djangoでアプリケーション名を変えたらmigrateができなくなってしまったときの対処方法をメモ

Last updated at Posted at 2021-03-08

###環境

Python 3.8.7
Django==2.2

###エラー内容

アカウントの編集とかの操作するアプリケーション名を変更して

python manage.py makemigrations

をしたら

Traceback (most recent call last):
略
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration socialaccount.0001_initial is applied before its dependency account_manage.0001_initial on database 'default'.

とエラーが発生。

python manage.py migrate

も同じエラー。
そこで、エラー文をググってみると、

があった!
書いてあるように、

python manage.py showmigraions

をやったら、前に作ったアプリケーションでmigrateしたデータが残ってた、、、。そりゃそうだな。
###解決方法
すべてのアプリケーションのmigrations直下の__init__.py以外のファイルを削除。

python manage.py makemigrations
python manage.py migrate

をしたら動いた!
