How to send letters with data to mail from the admin panel?

Question

Django

I extended the User class and you can create a user in the admin panel. Now I would like that when creating a user by the admin, all data is sent to him by mail. I know that this is very bad, but I would just like the password and login to come to the mail. here is my code.
models.py

class UserManager(BaseUserManager):
    def create_user(self, email, username, password=None):
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=UserManager.normalize_email(email),
            username=username)

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, username, password):
        user = self.create_user(email,
                                password=password,
                                username=username)
        user.is_admin = True
        user.save(using=self._db)
        return user


class User(AbstractBaseUser):
    email = models.EmailField(
        verbose_name='Электропочта',
        max_length=255,
        unique=True,
        db_index=True)
    username = models.CharField(verbose_name='Ник',  max_length=255, unique=True)
    first_name = models.CharField(verbose_name='Имя',  max_length=255, blank=True)
    last_name = models.CharField(verbose_name='Фамилия',  max_length=255, blank=True)
    date_of_birth = models.DateField(verbose_name='День рождения',  blank=True, null=True)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = UserManager()

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['email']

    def get_full_name(self):
        return '%s %s' % (self.first_name, self.last_name,)

    def get_short_name(self):
        return self.username

    def __unicode__(self):
        return self.email

    def has_perm(self, perm, obj=None):
        return True

    def has_module_perms(self, app_label):
        return True

    @property
    def is_staff(self):
        return self.is_admin

forms.py

class UserCreationForm(forms.ModelForm):
    password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)

    class Meta:
        model = User
        fields = ('email', 'username')

    def clean_password2(self):
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError("Passwords don't match")
        return password2

    def save(self, commit=True):
        user = super(UserCreationForm, self).save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user


class UserChangeForm(forms.ModelForm):
    password = ReadOnlyPasswordHashField()

    class Meta:
        model = User

    def clean_password(self):
        return self.initial["password"]

from account.models import User
from account.forms import UserChangeForm, UserCreationForm

    form = UserChangeForm
    add_form = UserCreationForm


    list_display = ('email', 'username', 'is_admin',)
    list_filter = ('is_admin',) 
    fieldsets = (
        (None, {'fields': ('email', 'username', 'password')}),

    filter_horizontal = ()

admin.site.register(User, UserAdmin)
admin.site.unregister(Group)

Answer 4

registered in models.py

def create_user(self, email, username, password=None):
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=UserManager.normalize_email(email),
            username=username)

        user.set_password(password)
        send_mail('Subject here', 'Here is the message.', '[email protected]', ['[email protected]'], fail_silently=False)
        user.save(using=self._db)
        return user

Error occurs while syncing database

ConnectionRefusedError: [WinError 10061] Подключение не установлено, т.к. конечн
ый компьютер отверг запрос на подключение

Answer 5

set up

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = '******@gmail.com'
EMAIL_HOST_PASSWORD =*********'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

The same error occurs

Answer 6

Do via signals: https://docs.djangoproject.com/en/1.6/topics/signals/
For example:

# signals.py

# -*- coding: utf-8 -*-
from django.db.models.signals import post_save
from django.dispatch import receiver
from django.core.mail import send_mail
from django.contrib.auth import get_user_model
from django.conf import settings

User = get_user_model()


@receiver(post_save, sender=User)
def send_notification(sender, instance, created, **kwargs):
    if created:
        # здесь можно провести дополнительную фильтрацию, например if instance.is_admin и т.п.
        send_mail(subject, body, settings.DEFAULT_FROM_EMAIL, instance.email)

In settings, you also specify DEFAULT_FROM_EMAILthe settings for sending mail.

Answer 7

typed in the command line

python -m smtpd -n -c DebuggingServer localhost:1025

after trying to synchronize the database, after entering the last field, an error occurs
