在我的URLConf中，我的URL被整齐地命名，所以我可以进行反向查找并保持一切干燥。 
 
 我的所有模板都扩展了一个名为base.html的通用模板。 在base.html ，在很多HTML框架中，我显示了一个登录表单。 
 
 我还有一个特定的视图，它使用Django提供的auth_views.login视图，它显示我的自定义模板login.html 。 与所有其他模板一样，此模板扩展了base.html模板。 
 
 在这种情况下，我希望base.html模板不会显示其登录表单（ login.html模板已经显示了登录表单）。 为了做到这一点， base.html要么知道它被用于扩展login.html ，要么知道导致base.html被扩展的命名URL的名称是'myapp-login' 。 
 
 你能建议一种方法吗？ 我正在考虑编写自己的视图，该视图将使用包含suppress_header_login_form var的额外上下文调用auth_views.login 。 基于此var， base.html模板可以禁止登录表单。 但是，我试图看看是否有更好的方法来实现这一目标。 

In my URLConf, I have my URLs neatly named so I can do reverse lookups and keep everything DRY.
 
All my templates extend a universal template named base.html. In base.html, amongst a lot of HTML framework, I display a login form.
 
I also have a specific view which uses Django's provided auth_views.login view, which displays my custom template login.html. This template, like all others, extend the base.html template.
 
In cases like this, I would like that the base.html template would not display its login form (the login.html template already is displaying a login form). In order to do this, base.html either needs to know that it is being used to extend login.html, or, know that the named URL which resulted in base.html being extended is has the name 'myapp-login'.
 
Can you suggest a way to do this? I am thinking of writing my own view which will call auth_views.login with extra context which includes a suppress_header_login_form var. Based on this var, the base.html template could suppress the login form. However, I am trying to see if there is a nicer way to accomplish this.
