私は私を提出しようとしているのではありませんフォーム、私はこれを取得している電子rror： <span class="help-inline">Select a valid choice. 29 is not one of the available choices.</span>。
トピックの選択した値に基づいて、AJAXを介してサブトピックドロップダウンリストのオプションを動的に生成しています。
私はrequest.POSTにsubtopicを見ることができますが、cleanメソッドになると、subtopicフィールドが消えます。
私は何が起こっているのかあまりわからないんだけど...
UPDATE
もう一つのサブトピックのための値がないとき、select要素がdisabled=disabledに設定されています。このように私のフォームを提出しようとすると、私はsubtopicフィールドを私の清潔な方法で得ることができます。フィールドが無効になっていないとき、私はそれを私のきれいな方法で得ることができません。それは、私が期待しているのとは逆の振る舞いです。
