gevent を使用して、gunicorn サーバーで Django アプリを実行しようとしています。gunicorn.conf 内で、すべてにモンキーパッチを適用しました。

def on_starting(server):
    from gevent import monkey
    monkey.patch_socket()

def post_fork(server, worker):
    import pymysql
    pymysql.install_as_MySQLdb()

更新: pymysql 0.5 で Django 1.5 を使用しています

Django を実行すると、次の例外が発生します。

ImportError at /
Exception Value: cannot import name SERVER_STATUS
Exception Location: /var/www/virtualenvs/myproject/local/lib/python2.7/site-packages/pymysql/connections.py in <module>, line 37

これはトレースバックです:

File "/var/www/virtualenvs/myproject/local/lib/python2.7/site-packages/pymysql/connections.py" in <module>
  37. from constants import SERVER_STATUS

ここで SERVER_STATUS をインポートできない理由がわかりません。このファイルは存在し、「python manage.py shell」内にこのファイルをインポートできます。つまり、「pymysql.constants import SERVER_STATUS から」機能します。

何かアドバイスはありますか？これは本当にばかげたバグだと想像できます...

前もって感謝します！

以下を移動してみてください。

import pymysql
pymysql.install_as_MySQLdb()

settings.py へ
