↑のDjangoのチャットボットをリンク先のページのドキュメントを元に、動かそうとしているのですが、「Build and run the app
locally」のところの、

```

    python manage.py makemigrations
    
```

を実行したところ下記エラーが出てきてしまいます。

```

```

インスタンス上のユーザー名・パスワード名が誤ってないかは何度も確認しているので、  
問題ないはずなのですが、何度やってもこのエラーが突破できません。  
様々検索した中で、

```

        C:\Users\ellay\Django-Dialogflow-GoogleVisionAPI>gcloud sql connect polls-instance2 --user=test
    ERROR: (gcloud.sql.connect) HTTPError 400: The incoming request contained invalid data.
    
```

上記のsql接続テストでエラーが出ていることが原因なのではとも思っておりますが、  
その先の原因特定・解決まで至っておりません。

またDjangoのsetting.py上の記載は下記になっています。

```

        DATABASES = {
            'default': {
                'ENGINE': 'django.db.backends.mysql',
                'HOST': '/cloudsql/michatbot-250809:us-central1:polls-instance2',
                'USER': 'test',
                'PASSWORD': '',
                'NAME': 'polls',
            }
        }
    else:
        # Running locally so connect to either a local MySQL instance or connect to
        # Cloud SQL via the proxy. To start the proxy via command line:
    
        #     $ cloud_sql_proxy -instances=[INSTANCE_CONNECTION_NAME]=tcp:3306
        #
        # See https://cloud.google.com/sql/docs/mysql-connect-proxy
        DATABASES = {
            'default': {
                'ENGINE': 'django.db.backends.mysql',
                'HOST': '127.0.0.1',
                'PORT': '3306',
                'NAME': 'polls',
                'USER': 'test',
                'PASSWORD': '',
            }
        }
    # [END db_setup]
    
```

question
mysql django dialogflow
Djangoでcloud sqlに接続出来ない。
`"Access denied for user 'test'@'localhost' (using password:
NO)"`のエラーは`test`というユーザーで`localhost`からMySQLにアクセスする権限が無いということです。

なので、以下のSQLを実行したら、このエラーは解消されるのではないかと思います。

```

    mysql> grant all privileges on *.* to test@localhost identified by '' with grant option;
    
```

"Access denied for user"でググるとたくさん情報が出てきます。
