【中文标题】NoReverseMatch django 1.4 管理员

【问题描述】：

我将一个项目从 1.1 迁移到 1.2，然后迁移到 1.3，所有这些都完美无缺。但是，当我将版本升级到 1.4 时，我不断收到一个

NoReverseMatch at /admin/<app_name>/<model_name>/
Reverse for 'app_list' with arguments '()' and keyword arguments ''app_label': ''' not found.

所有其他管理功能似乎都可以正常工作，但每次我尝试查看列表时，都会收到此 NoReverseMatch 错误。

我的管理员网址是：

(r'^admin/', include(admin.site.urls)),

这是我的回溯：

Template error:

【问题讨论】：

您似乎忘记在您的INSTALLED_APPS 配置中包含一个应用程序。您是否按照these 的步骤使用管理页面？

您好，谢谢，我确实遵循了这些步骤。我想也许我错过了设置文件上的一些新的默认应用程序，甚至检查了顺序。问题依旧。无论如何，我发现了问题（而且很愚蠢），所以我会发布答案。

【参考方案1】：

我的错误最终相当愚蠢。我的一个自定义上下文处理器重新定义了“cl”上下文变量，因此使以下标记失败：

% url 'admin:app_list' app_label=cl.opts.app_label %

我只需要对我自己的上下文处理器和模板进行一些更改（并使用更好的上下文处理器变量名称）。

注意：我不知道为什么这之前没有让我感到困扰。理论上，即使在 1.1 中，它也应该是一个问题。
