Introduction Logout user Change password

This assumes that the user app has already been created (see introduction)

To support tabindex in the login we need to create a Django filter

In the home directory create a directory call templatetags with an init.py

in templatetags create app_filters.py:

 from django import template

 register = template.Library()    

 @register.filter
 def tabindex(value, index):
     """Add a tabindex attribute to the widget for a bound field."""
     value.field.widget.attrs['tabindex'] = index
     return value

This will be used in the template (see below).

In forms.py

 from django import forms
 from django.contrib.auth.models import User


 class LoginForm(forms.ModelForm):
     username = forms.CharField(label='User name', max_length=30)
     password = forms.PasswordInput()

     class Meta:
         model = User
         fields = '__all__'

         widgets = {'password': forms.PasswordInput()}

In users/urls.py:

 urlpatterns = [
         ...
         path(r'login/', views.login_view, name='login'),
     ]

In views.py

(This assumes the import statements in logout have already been inserted.)

 from django.http import HttpResponseRedirect

 def login_view(request):
     form_context = {'login_form': LoginForm,}
     url = "users/login.html"
     if request.method == 'POST':
         username = request.POST['username']
         password = request.POST['password']
         user = authenticate(username=username, password=password)
         if user is not None:
             if user.is_active:
                 login(request, user)
                 return HttpResponseRedirect(RETURN_FROM_LOGIN_URL)
             else:
                 messages.error(request, 'Your account is not enabled!')
             context = {}
         else:
             messages.error(request, 'Your username or password was not recognized!')
             context = form_context
     else:
         context = form_context
     return render(request, url, context)

And in login.html

 {% extends "base.html" %}
 {% load app_filters %}
 {% block content %}
     <br>
     {% if form.errors %}
         <p>Your username and password didn't match. Please try again.</p>
     {% endif %}

     {% if next %}
         {% if user.is_authenticated %}
             <p>Your account doesn't have access to this page. To proceed,
             please login with an account that has access.</p>
         {% else %}
             <p>Please login to see this page.</p>
         {% endif %}
     {% endif %}

     <form method="post" action="{% url 'login' %}">
     {% csrf_token %}
         <table>
             <tr>
                 <td></td>
                 <td><div></div></td>
                 <td rowspan="2"><div tabindex="3"><button type="submit" class="btn btn-success">Login</button></div></td>
             </tr>
             <tr>
                 <td></td>
                 <td><div></div></td>
             </tr>
         </table>
     </form>
     {% if messages %}
         <ul class="messages">
             {% for message in messages %}
             <li {% if message.tags %} class=""{% endif %}></li>
             {% endfor %}
         </ul>
     {% endif %}
 {% endblock %}
