Django CBV: Easy access to url parameters in get_context_data()?

由 大兔子大兔子 提交于 2019-12-07 17:09:20
问题 I understand that the standard way of accessing named url parameters in a custom get_context_data() method is through self.kwargs . However, the self.kwargs syntax becomes awkward, especially when handling a significant number of parameters. So, I've been resorting to something like this at the top of every get_context_data() method -- just to get easy-to-handle local variables: def get_context_data(self, **kwargs): var1, var2, var3, var4, var5 = [self.kwargs[x] for x in ['var1', 'var2',

Django 1.11 404 Page while Debug=True

由 时间秒杀一切 提交于 2019-12-07 15:24:39
问题 Without making things difficult , I just want to show a special 404 render with staticfiles. If you set DEBUG = False you can use in urls.py handler404 = 'app.views.handler404' But it is without staticfiles. I don't want to install a web server for a simple app. With DEBUG = True in urls url(r'^404/$', views.handler400) is not overriding the default Page not found (404) page. What is the easy way to achieve a render e.g. when you type localhost/asdfhjfsda with staticfiles when DEBUG=True ?

Passing request.user to template in Django

由 蓝咒 提交于 2019-12-07 14:47:57
问题 Is there another way to get the request.user by not passing it from the views? I think passing request.user from all functions in views to the template is quite wrong. Is there any method or way that the template will get the user or any object in the database? 回答1: By default (I am talking about Django version 1.3) you do not need change TEMPLATE_CONTEXT_PROCESSORS. Because default value already contains *django.contrib.auth.context_processors.auth*. So to your question: By default, you
