Flask、SQLAlchemy、および WTForms を使用する Web アプリケーションと、必要な Flask 拡張機能を使用して、すべてを機能させています。MySQL はutf8_bin
すべてのテーブルと列に使用しています。
いくつかの漢字を挿入し、phpMyAdmin はそれらを正しく表示しますが、ページを開こうとするたびに次の例外が発生します。
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 0: ordinal not in range(128)
表示したいフィールドを表示する必要があることは理解decode('utf8')
していますが、これは SQLAlchemy によって処理されるべきではありませんか?
これを機能させる唯一の方法は、結果のリストを繰り返し処理し、次のようなことを行うことでした。
object.property = object.property.decode('utf8')
しかし、明らかにこれは手動で行う必要はありません。私は何が欠けていますか?
