これらのエラーは何を意味しますか？ djangoのmysql

Question

私は例として見ていたプログラムを実行しようとしています。ショッピングウェブサイトのように、Djangoで提供されている元のデータベースの代わりにMySQLデータベースを使用しています！私はちょうど誰かがこれらのエラーの意味を理解しているかどうかを見たいと思った？任意の情報をいただければ幸いです！私はウェブページのコードを提供していただろうが、それはあまり適合しないだろう！

Answer 1

これは、MySQLデータベースへの接続に使用している接続文字列（Djangoのデータベース認証情報）が間違っていることを意味します。 settings.pyであなたのユーザ名、パスワード、ホスト、ポート、DB名を確認し、データベースがサーバからの接続を受け入れていることを確認してください。

Answer 2

チェックsettings.py

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.mysql', 
     'NAME': 'djangocrud', 
     'USER':'root', 
     'PASSWORD':'pass$123', 
     'HOST':'127.0.0.1', 
     'PORT':'3306', 
    } 
}
