Djangoのウェブサイト - TemplateDoesNotExist at/edit/117/

Question

私はUpdateViewを使ってフォームを使ってデータを編集しています。

TemplateDoesNotExist at /edit/117/ (or other pk...) 

DevOpsWeb/serverlist_form.html 
Request Method: POST 
Request URL: http://devopsweb:8000/edit/117/ 
Django Version: 1.11.6 
Exception Type: TemplateDoesNotExist 
Exception Value:  
DevOpsWeb/serverlist_form.html 

1. 私はこれを取得なぜ：

   モーダルを編集して、私が編集し、確認をクリックした後、私はエラーを取得することができ、いくつかの形でポップアップされる[編集]ボタンをclikingした後、エラー？

2. 私がモーダルを取得したときに、PKの情報が空白になるのはなぜですか？

誰でもこれらの質問がありますか？私は本当にこだわっ:( はありがとう

Answer 1

あなたはUpdateView属性の一つ、template_name_suffix、template_nameまたはget_templates_names()をオーバーライドしていないので、あなたのビューが見られるデフォルトのテンプレート名は<model_name>_form.htmlです。あなたはそのテンプレートを持っていません
