Django 网站 - TemplateDoesNotExist 在 /edit/117/

Posted 2023-02-24

【中文标题】Django 网站 - TemplateDoesNotExist 在 /edit/117/

【英文标题】：Django Website - TemplateDoesNotExist at /edit/117/

【发布时间】：2018-05-10 18:26:06

【问题描述】：

我正在使用 UpdateView 使用表单来编辑数据。

单击“编辑”按钮后，会弹出一个模式，其中包含一些可以编辑的表单，然后在我编辑并单击“确认”后出现错误：

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

为什么会出现此错误？ 为什么我拿到modal的时候PK的信息是空白的...？

有人知道这些问题吗？我真的被困住了:( 谢谢！

【问题讨论】：

模板中有serverlist_form.html 文件吗？

不，我从来没有这个模板......但问题是我使用的是一个类似于弹出窗口的模式......然后当我点击确认它应该重定向到相同页。我的编辑以前可以工作..我做了一些更改，从那以后我遇到了这个错误..

现在运行完美。你知道在我点击编辑而不是空白表单之前如何获取数据吗？

【参考方案1】：

由于您没有覆盖UpdateView 属性、template_name_suffix、template_name 或get_templates_names() 之一，因此您的视图将查看的默认模板名称是<model_name>_form.html。而你没有那个模板

【讨论】：

没错。我没有那个模板，因为我使用的是同一个页面，只是弹出一个模式（一个小窗口），在我按下确认后它应该带我回到同一个页面，我点击了按钮。我应该在视图中添加什么？我应该覆盖哪个属性？

@EilonAshkenazi 尝试使用template_name = 'index.html'

在我点击确认后在 UpdateVIew 下添加后，我进入 devopsweb/edit/117 并成功显示主页但没有任何数据...我尝试添加 - 帖子 = serverlist.objects。 all() 但它仍然没有显示任何内容，并且主页在没有任何数据库条目的情况下工作..就像它是空的..也许我需要另一个 Get 请求？就像也许我应该以某种方式调用 get 函数来在编辑后获取所有数据库？

另外，为什么在 PostDelete 下我不需要做 template_name？删除后成功将我重定向到主页

@EilonAshkenazi 因为它只是一个不需要模板的发布方法，它只是发送请求并重定向到提供的success_url
