If you want the actual HTTP Host header, see Daniel Roseman's comment on @Phsiao's answer. The other alternative is if you're using the <a href="http://docs.djangoproject.com/en/dev/ref/contrib/sites/#ref-contrib-sites" rel="noreferrer">contrib.sites framework</a>, you can set a canonical domain name for a Site in the database (mapping the request domain to a settings file with the proper SITE_ID is something you have to do yourself via your webserver setup). In that case you're looking for:

<pre><code>from django.contrib.sites.models import Site

current_site = Site.objects.get_current()
current_site.domain
</code></pre>

you'd have to put the current_site object into a template context yourself if you want to use it. If you're using it all over the place, you could package that up in a template context processor.

blocks|key|1449300|text|作为对Carl+Meyer的补充，您可以像这样制作一个上下文处理器：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1449301|module.context_processors.py|1449302|from+django.conf+import+settings

Complementing Carl Meyer, you can make a context processor like this:

<h3>module.context_processors.py</h3>

<pre><code>from django.conf import settings

def site(request):
 return {'SITE_URL': settings.SITE_URL}
</code></pre>

<h3>local settings.py</h3>

<pre><code>SITE_URL = 'http://google.com' # this will reduce the Sites framework db call.
</code></pre>

<h3>settings.py</h3>

<pre><code>TEMPLATE_CONTEXT_PROCESSORS = (
 ...
 "module.context_processors.site",
 ....
 )
</code></pre>

<h3>templates returning context instance the url site is {{ SITE_URL }}</h3>

you can write your own rutine if want to handle subdomains or SSL in the context processor.

Quick and simple, but not good for production:

(in a view)

<pre><code> request.scheme # http or https
 request.META['HTTP_HOST'] # example.com
 request.path # /some/content/1/
</code></pre>

(in a template)

<pre><code>{{ request.scheme }} :// {{ request.META.HTTP_HOST }} {{ request.path }}

Be sure to use a <a href="https://docs.djangoproject.com/en/1.7/ref/templates/api/#django.template.RequestContext">RequestContext</a>, which is the case if you're using <a href="https://docs.djangoproject.com/en/1.7/topics/http/shortcuts/#render">render</a>.

I figure what we want is an alternative to the existing <code>url</code> tag, so I wrote a new tag:
<pre><code>from django.template import Library
from django.urls import reverse

@register.simple_tag(takes_context = True)
def fullURL(context, name, *args, **kwargs):
 request = context['request']
 return f'{request.scheme}://{request.get_host()}{reverse(name, args = args, kwargs = kwargs)}'
</code></pre>
Then in your template you can have this...
<pre><code>{% extends &quot;myapp/email/email_base.html&quot; %}

{% load mytags %} {# Replace mytags with whatever the name of your custom tags calss is. #}

{% block content %}
&lt;p&gt;You can use &lt;a href=&quot;{% fullURL 'signup' %}&quot;&gt;this link&lt;/a&gt; to get started with your account. We look forward to seeing you soon!&lt;/p&gt;
{% endblock content %}
</code></pre>
Then when you generate this, you just need to remember to pass the <code>request</code> into the <code>context</code>, like so...
<pre><code>from django.template.loader import render_to_string

def sendEmail(subject, to, template, **context):
 html = render_to_string(f'myapp/email/{template}.html', context | {'subject': subject})
 # ... and so on with the rest of my function for sending email...
</code></pre>

How do I get the domain name of my current site from within a Django template? I've tried looking in the tag and filters but nothing there.

How can I get the domain name of my site within a Django template?
