私の目標は、フォームを介してデータベースにデータを追加し、編集フォームで編集可能にすることです。Python Djangoは、データをフォームでデータベースに編集します（django v.1.9.4）
マイエラー：
Exception Type: NoReverseMatch at /testtable/car/new/
Exception Value: Reverse for 'car_list' with arguments '()' and keyword arguments '{'pk': 2}' not found. 0 pattern(s) tried: []
と次の問題がcar_edit.htmlするために、テンプレート/ car_list.html内のデータ を編集するためのリンクを作成する方法です。
<td><a href=>Edit</a> <a href="">Delete</a></td>
<td><a href="{% url 'tabletest:car_edit' pk=car.pk %}">Edit</a> <a href="">Delete</a></td>
私はそれが動作エクスプローラhttp://localhost:8000/testtable/car/1/に手動で入力すると、私は、データベース内の最初の記事の詳細を参照してください、しかし、PK引数でフォームが作業をdoesntの。
