This lesson focuses on implementing the password reset email.

Create a view for requesting a password reset email

In this lesson, we’ll build a view to be called when a user requests a password reset email. Our view’s primary task is sending the user an email containing a password reset link. We can create the view class in our views.py file like this.

Python 3.8

class RequestPasswordResetEmailView(generics.GenericAPIView):
    serializer_class = RequestPasswordResetEmailSerializer
    def post(self, request):
        serializer = self.serializer_class(data=request.data)
        serializer.is_valid(raise_exception=True)
        
        Email = request.data['email']
        
        if User.objects.filter(email=Email).exists():
            user = User.objects.get(email=Email)
            uidb64 = urlsafe_base64_encode(smart_bytes(user.id))
            token = PasswordResetTokenGenerator().make_token(user)
            current_site = get_current_site(request=request).domain
            relativeLink = reverse('password-reset-confirm', kwargs={'uidb64': uidb64, 'token': token})
            absurl = 'https://' + current_site + relativeLink 
            
            email_body = "Hello! \n Use the link below to reset your password \n" + absurl
            data = {'email_body': email_body,'to_email': user.email,
                    'email_subject':'Reset your password'}
            
            Mail.send_email(data)
            
        return Response({'Success': 'Password reset email sent'}, status=status.HTTP_200_OK)

In the code above, we start by declaring a serializer class in our RequestPasswordResetEmailView class in line 13, and then we create a post() method in line 16. In the post() method:
