Я пытаюсь использовать общий вид входа в систему, предоставляемый Django. Я хочу, чтобы форма регистрации и входа была на одной странице. Вот мой urls.py
from django.conf.urls import patterns, include, url
from myApp.forms import UsersForm
urlpatterns = patterns('',
url(r'^$', 'django.contrib.auth.views.login', {'template_name': 'templates/login.html', 'authentication_form':UsersForm}),
)
а это мой login.html
<html>
<body>
<form method="post" action="">{% csrf_token %}
{{ authentication_form.first_name }} {{authentication_form.last_name }} <br>
{{ authentication_form.username }} {{ authentication_form.password }} <br>
<input type="submit" value="Register"/>
</form>
{% for field, error in form.errors.items %}
{% if forloop.counter == 1 %}
{{ error | striptags }}
{% endif %}
{% endfor %}
<form method="post" action="{% url 'django.contrib.auth.views.login' %}">{% csrf_token%}
{{authentication_form.username.label_tag}}
{{authentication_form.username}}
{{authentication_form.password.label_tag}}
{{authentication_form.password}}
<input type="submit" value="login" />
<input type="hidden" name="next" value="{{ next }}" />
</form>
</body>
</html>
Когда я запускаю сервер и перехожу к 127.0.0.1, отображаются только кнопки входа и регистрации, а фактические поля - нет (я не могу ничего вводить где-либо на странице, есть только две кнопки, одна из которых говорит 'вход в систему "и другой, который гласит" зарегистрироваться ". Там просто пустое пространство, где должны быть фактические поля. Почему поле для имени пользователя, пароля, имени и фамилии не отображается?
РЕДАКТИРОВАТЬ: когда я меняю authentication_form.username на просто form.username, он выдает ошибку шаблона, говорящую
'WSGIRequest' object has no attribute 'get'
и обратная связь с этим

Мой общий вид входа в систему - это просто
