То, как лучше всего работать с, Истекает заголовок в ASP.NET MVC?

Хорошо, я нашел рабочее решение для этого. Вот мое решение.

Я изменил forms.py следующим образом

from django import forms
from accounts.tasks import send_mail
from django.contrib.auth.forms import PasswordResetForm as PasswordResetFormCore


class PasswordResetForm(PasswordResetFormCore):
    email = forms.EmailField(max_length=254, widget=forms.TextInput(
        attrs={
            'class': 'form-control',
            'id': 'email',
            'placeholder': 'Email'
        }
    ))

    def send_mail(self, subject_template_name, email_template_name, context, 
                  from_email, to_email, html_email_template_name=None):
        context['user'] = context['user'].id

        send_mail.delay(subject_template_name=subject_template_name, 
                        email_template_name=email_template_name,
                        context=context, from_email=from_email, to_email=to_email,
                        html_email_template_name=html_email_template_name)

И измененный tasks.py похож на следующий

from __future__ import absolute_import, unicode_literals
from accounts.models import User
from django.contrib.auth.forms import PasswordResetForm


@shared_task
def send_mail(subject_template_name, email_template_name, context,
              from_email, to_email, html_email_template_name):
    context['user'] = User.objects.get(pk=context['user'])

    PasswordResetForm.send_mail(
        None,
        subject_template_name,
        email_template_name,
        context,
        from_email,
        to_email,
        html_email_template_name
    )
