Settings parameters
You have to add these parameters to the settings, you have to include all of them except the last one:
def verified_callback(user):
user.is_active = True

EMAIL_MAIL_PLAIN = 'mail_body.txt'
EMAIL_TOKEN_LIFE = 60 * 60
EMAIL_PAGE_TEMPLATE = 'confirm_template.html'
EMAIL_PAGE_DOMAIN = 'http://mydomain.com/'

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'mymail@gmail.com'
EMAIL_HOST_PASSWORD = 'mYC00lP4ssw0rd' # os.environ['password_key'] suggested
EMAIL_USE_TLS = True
In detail:
EMAIL_VERIFIED_CALLBACK: the function that will be called when the user successfully verifies the email. Takes the user object as argument.EMAIL_FROM_ADDRESS: this can be the same asEMAIL_HOST_USERor an alias address if required.EMAIL_MAIL_:SUBJECT: the mail default subject.HTML: the mail body template in form of html.PLAIN: the mail body template in form of .txt file.
EMAIL_TOKEN_LIFE: the lifespan of the email link (in seconds).EMAIL_PAGE_TEMPLATE: the template of the success/error view.EMAIL_PAGE_DOMAIN: the domain of the confirmation link (usually your site's domain).
For the Django Email Backend fields look at the official documentation.
Templates examples
The EMAIL_MAIL_HTML should look like this ({{ link }}(str), {{ expiry }}(datetime) and user(Model) are
passed during the rendering):
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Email Confirmation</title>
</head>
<body>
<h1>You are almost there, {{ user.username }}!</h1><br>
<h2>Please click <a href="{{ link }}">here</a> to confirm your account</h2>
<h2>The token expires on {{ expiry|time:"TIME_FORMAT" }}</h2>
</body>
</html>
The EMAIL_MAIL_PLAIN should look like this ({{ link }}(str), {{ expiry }}(datetime) and user(Model) are
passed during the rendering):
You are almost there, {{ user.username }}!
Please click the following link to confirm your account: {{ link }}
The token expires on {{ expiry|time:"TIME_FORMAT" }}
The EMAIL_PAGE_TEMPLATE should look like this ({{ success }}(bool), {{ user }}(Model)
and {{ request }}(WSGIRequest) are passed during the rendering):
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Confirmation</title>
</head>
<body>
{% if success %}
{{ user.username }}, your account is confirmed!
{% else %}
Error, invalid token!
{% endif %}
</body>
</html>
Email sending
After you have created the user you can send the confirm email
from django.shortcuts import render
from django.contrib.auth import get_user_model
from django_email_verification import send_email
def my_functional_view(request):
...
user = get_user_model().objects.create(username=username, password=password, email=email)
user.is_active = False # Example
send_email(user)
return render(...)
send_email(user) sends an email with the defined template (and the pseudo-random generated token) to the user.
IMPORTANT: You have to manually set the user to inactive before sending the email.
If you are using class based views, then it is necessary to call the superclass before calling the send_confirm
method.
from django.views.generic.edit import FormView
from django_email_verification import send_email
class MyClassView(FormView):
def form_valid(self, form):
user = form.save()
returnVal = super(MyClassView, self).form_valid(form)
send_email(user)
return returnVal
Token verification
You have to include the urls in urls.py
from django.contrib import admin
from django.urls import path, include
from django_email_verification import urls as email_urls
urlpatterns = [
path('admin/', admin.site.urls),
...
path('email/', include(email_urls)),
]
When a request arrives to https.//mydomain.com/email/<base64-email>/<token> the package verifies the token and:
- if it corresponds to a pending token it renders the
EMAIL_PAGE_TEMPLATEpassingsuccess=Trueand deletes the token - if it doesn't correspond it renders the
EMAIL_PAGE_TEMPLATEpassingsuccess=False
Console backend for development
If you want to use the console email backend provided by django, then define:
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
You can use all the django email backends and also your custom one.
Custom salt for token generation
Pass the custom_salt keyword parameter to the send_confirm method as follows:
send_email(user, custom_salt=my_custom_key_salt)
