Django: How to get the root path of a site in template?

Question

I want to design a go back home button for my site and how can I get the root path of my site in the template so I can do something like this:

Answer 1

I found a trick, Use this tag:

{{ HTTP_HOST }}

you could do:

<a href="{{ HTTP_HOST }}"> back home <a>

or

<a href="{{ HTTP_HOST }}/what_you_want"> back home <a>

Answer 2

I think the proper way here is use the {% url %} tag and I'm assuming that you have a root url in your url conf.

urls.py

url(r'^mah_root/$', 'someapp.views.mah_view', name='mah_view'),

Then in your template:

<a href="{% url mah_view %}">Go back home</a>

Answer 3

Referring to standard Django example:

urlpatterns = [
    path('', views.index, name='index'),
]

Then template code:

href="{% url 'index' %}"

will also work.

Answer 4

You should be able to access the get_host() method of the request:

<a href="http://{{ request.get_host() }}">Go back home</a>

Though you could probably also do:

<a href="/">Go back home</a>

Answer 5

this is what i did:

in urls.py:

from django.contrib import admin
from django.urls import include, path
from django.views.generic import TemplateView

urlpatterns = [
    path('blog/', include('blog.urls')),
    path('admin/', admin.site.urls),
    path('', TemplateView.as_view(template_name='landing.html'), name='landing')
]

then, in whatever view:

<a href="{% url 'landing' %}">Site Title</a>

this will resolve to localhost:8000/ or site.domain.com/ whichever you are using, when you click the link
