Django Adminログイン画面でエラーが発生しました

Question

私はDjangoでWeb Developmentを初めて利用しています。学習のためにDjangoチュートリアル（PollsApp）に従っています。私がDjango Adminパネルを起動しようとしているとき、 'tuple'型の非intでシーケンスを掛けることはできません。

誰かが迷っていることをお伝えできますか？

編集 ここでは、settings.pyに私のデータベースを行く：あなたは、ジャンゴの

DATABASES = {

     'NAME': 'polls', 
     'USER': '.....', 
     'PASSWORD': '.....', 
     'HOST': 'localhost', # Or an IP Address that your DB is hosted on 
     'PORT': '4928', 
    } 
} 

Answer 1

どのバージョンを使用していますか？私は同じ問題を抱えています... Django/MySQL側の問題のようです。

あなたは

{Pythonのパッケージディレクトリ} /mysql/connector/django/operations.pyにbulk_insert_sqlを更新する必要があります。

それは次のようになります。

def bulk_insert_sql(self, fields, placeholder_rows): 
    """ 
     Format the SQL for bulk insert 
    """ 
     placeholder_rows_sql = (", ".join(row) for row in placeholder_rows) 
     values_sql = ", ".join("(%s)" % sql for sql in placeholder_rows_sql) 
     return "VALUES " + values_sql
