django-registration, error 500 after submitting the form

Question

I am trying to make signup form using django-registration app. But, when I submit registration form I get message "Server Error (500)"? Please, help me - what I do wrong?

templates/registration/registration_form.html:

<form method="post" action="">{% csrf_token %}
    <dl class="register">
        {% for field in form %}
            <dt>{{ field.label_tag }}</dt>
            <dd class="clearfix">{{ field }}
                {% if field.help_text %}<div class="clearfix">{{ field.help_text }}</div>{% endif %}
                {% if field.errors %}<div class="myerrors clearfix">{{ field.errors }}</div>{% endif %}
            </dd>
        {% endfor %}
    </dl>
    <input type="submit" value="Register" / class="clearfix">
</form>

urls.py:

url(r'^accounts/', include('registration.backends.default.urls')),

I ran smtp server for testing of mail sending:

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

There are no message with email at console

settings.py:

ACCOUNT_ACTIVATION_DAYS = 2 #
AUTH_USER_EMAIL_UNIQUE = True
EMAIL_HOST = 'localhost'
EMAIL_PORT = 1025
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_USE_TLS = False
DEFAULT_FROM_EMAIL = 'info@google.ru'

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.admin',
    'registration',
)

I created templates:

1.activation_email_subject.txt
Activation – {{ site }}

2.activation_email.txt
Follow {{ site }}/accounts/activate/{{ activation_key }}/

3.activate.html
Activated. <a href="{% url auth_login %}">Login</a> to site.

4.activation_email_subject.txt
Activation – {{ site }}

5.login.html
...

6.activation_complete.html
    activation_complete

7.activation_email_subject.txt
    Activation – {{ site }}

8.registration_complete.html
    Complete

9.logout.html
...

It looks like you swapped the default auth.User for a custom users.User.

if you want to use django-registration with a custom User class, you need to use a custom registration form, too. From the source code:

Note that all of these forms assume Django's bundle default User model; since it's not possible for a form to anticipate in advance the needs of custom user models, you will need to write your own forms if you're using a custom model.

You need to re-implement the registration form for your custom User and tell django-registration to use it (set the form_class attribute on your registration view)
