问题描述
问题是:在Django模板中编写URL的正确方法是什么?
Question is: What's the right way of writing URL in Django templates?
如果我明确地编写它们(像这样):
If I write them explicitly (like this):
some_template.html
{% extends "base.html" %}
{% block someblock %}
<a href="/some_url">Anchor</a>
{% endblock someblock %}
然后我决定更改我的URL方案必须同时更改模板和urls.py模块(这似乎与DRY原理冲突)
and then I decide to change my URL scheme I will have to change both - template and urls.py module (Seems this way conflicts with the DRY principles)
另一种方法是使用变量(像这样):
Another way is to use variables (like this):
some_template.html
{% extends "base.html" %}
{% block someblock %}
<a href="{{ url_var }}">Anchor</a>
{% endblock someblock %}
views.py
def some_url (request):
return HttpResponse('Hello, world!')
def another_url (request):
return render_to_response('some_template.html', {'url_var': reverse('some_url')}
但是在这种情况下,如果我使用模板继承,则必须在上下文中指定所有url变量(也用于父模板)。
But in this case if I use template inheritance I have to specify in context ALL of the url variables (also for the parent templates). Probably it is not a good way too.
那是什么决定?
推荐答案
Use named urls and the {% url %}
tag.
urlpatterns = [
#...
url(r'^articles/$', views.archive, name='news-archive'),
#...
]
{% url 'news-archive' %}
