【中文标题】覆盖管理模板时出现 TemplateSyntaxError【英文标题】：TemplateSyntaxError when overriding admin templates 【发布时间】：2020-04-21 14:36:53 【问题描述】：

我需要从 Django Admin 覆盖 index.html 模板。按照文档，我在 templates/admin 目录中创建了一个 index.html 文件，并从此处粘贴了原始内容 https://github.com/django/django/blob/master/django/contrib/admin/templates/admin/index.html

我收到了这个错误：

TemplateSyntaxError at /admin/

Invalid block tag on line 31: 'translate', expected 'elif', 'else' or 'endif'. Did you forget to register or load this tag?

Environment:


Request Method: GET
Request URL: http://127.0.0.1:8000/admin/

【问题讨论】：

但我从原件复制/粘贴。为什么默认模板不会发生此错误？您是否逐字粘贴了整个文件？您是否在模板顶部加载 i18n？您似乎也没有安装LocaleMiddleware。见docs.djangoproject.com/en/3.0/topics/i18n/translation 和docs.djangoproject.com/en/3.0/ref/middleware/… @Selcuk 是的，我确实复制/粘贴了整个文件并加载了 i18n。我添加了中间件，但没有解决问题 【参考方案1】：

我使用的是 Django 3.0.1，但在 GitHub 中复制了 3.0.2 的模板
