Django signal get request full path - django

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

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=MyModel)
def my_function_without_request(sender, instance, **kwargs):
current_site = Site.objects.get_current()
domain = current_site.domain
# Do something
To enable the sites framework, follow these steps:
Add 'django.contrib.sites' to your INSTALLED_APPS setting.
Define a SITE_ID setting: SITE_ID = 1
Run migrate.

To set the correct name and domain for your project, you can use a data migration.
To start, make an empty migration file you can work from (Django will put the file in the right place, suggest a name, and add dependencies for you):
python manage.py makemigrations --empty yourappname
Then, open up the file and create a new function and have RunPython use it.
from django.contrib.sites.models import Site
from django.db import migrations
def set_name_and_domain():
one = Site.objects.all()[0]
one.domain = 'yourdomain.com'
one.name = 'Your Name'
one.save()
class Migration(migrations.Migration):
dependencies = [
('yourappname', '0001_initial'),
]
operations = [
migrations.RunPython(set_name_and_domain),
]
All of this will save your domain and site name in your database where you can access it without having the request object. So far I have not found a better way to do this.

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 %}
