NoReverseMatchエラー：引数を持つ「episodeshowlinks」「（）」のリバースとキーワード引数「{}」私はまだ考え出したていないいくつかの理由について

今、すべてうまくいきました。入力フィールドは正常に機能していて、データベースにポストしていました。別のテンプレートへのリダイレクトは今日までうまくいっていました。問題は私のform_chapter_marks.htmlテンプレートの<a class="btn btn-primary box-shadow--6dp" href="{% url 'podfunnel:episodeshowlinks' %}" role="button"><i class="fa fa-chevron-right pull-right" aria-hidden="true"></i>&nbsp Next</a>の下にあるようですが、以前に問題がなかったときにエラーが表示されている理由がわかりません。

ここで助けていただければ幸いです。 -------------------

Answer 1

私はあなたがすべての残りの部分を示してきた理由はわからないんだけどそのコードのURLとテンプレートフラグメントで十分です。

あなたが引用している部分には、{% url 'podfunnel:episodeshowlinks' %}と呼んでいることが示されています。しかし、あなたのURLとエラーメッセージは、episodeshowlinksという名前の唯一のパターンが引数：production_idを要求していることを示しています。 URLタグに渡す必要があるので、生成するURLを知ることができます。

一般に、あなたのURLは非常に壊れているように見えます。私は、なぜあなたが "episodeshowlinks /"という接頭辞を持つ2つのURLを持っているのか理解できません。これは、production_idを取るURLと、show_idを取るURL、 "episodeshowlinks_edit"という名前の第2のURLです。 Djangoがそれらを区別するための方法はないので、Djangoは常に最初のものを呼び出すでしょう。neverはkwargsで "showlink_id"を取得します。
