Django signal get request full path

Question

I wrote a signal in my django project, inside I want to send an email with the full path of my website. But to do so, I need to get the request object inside the signal, how could I do that? Thanks.

    @receiver(pre_save, sender=AccessRequest)
    def email_if_access_true(sender, instance, **kwargs):
        #How can I get the full path of my website here?
        pass

Answer 1

If you don’t have access to the request object, you can use the get_current() method of the Site model’s manager.

from django.contrib.sites.models import Site

@receiver(pre_save, sender=AccessRequest)
def email_if_access_true(sender, instance, **kwargs):
    current_site = Site.objects.get_current()
    if current_site.domain == 'foo.com':
        #do other stuff here
    else:
        pass

you need to ensure that you defined SITE_ID=1 in your settings

Answer 2

Put following code in your pre_save signal receiver:

from django.contrib.sites.models import get_current_site
current_site = get_current_site(request=None)
domain = current_site.domain
protocol = "http"

You can generate absolute url to your website in email by passing required context variables to template. If access_request is instance in your case and there is one get_abosulte_url() method in your AccessRequest model, then following line in email template will give you absolute url.

{{ protocol }}://{{ domain }}{% access_request.get_absolute_url %}
