odoo：内部サーバーエラー、バグはどこですか？

Question

私はWindows上でodooサーバーを実行しています。有名な "500 Inernal server error"を取得していますが、今はバグの原因ではありません！

サーバーを停止/再起動してもエラーは発生します。

ログファイルを探して、「openerp-server.txt」が見つかりました。

バグがある：

これは、ログファイルの最後のですか？

Answer 1

これはおそらくself.pool.get(model_name)に渡されたモデル名の誤植で、おそらくNoneを返し、遅れて失敗します。コード内のself.pool.get(model_name)をself.pool[model_name]に置き換えると、バグの原因となるクラッシュが発生します。
