Django View Questions

[G Z]

so I have a problem when ever I go to /manage/ it takes me to index and im not sure why.

Urls.py

url(r'^', views.IndexView.as_view(), name='index'),

url(r'^manage/$', views.ManageView.as_view(), name='manage'),

Views.py

from django.shortcuts import get_object_or_404, render

from django.http import HttpResponseRedirect

from django.contrib.auth import authenticate, login

from django.contrib.auth.decorators import login_required

from django.contrib.auth import logout

from django.views import generic

from portal.models import Customer

from django.views.generic import TemplateView

class IndexView(generic.ListView):

      model = Customer

      template_name = 'index.html'

      context_object_name = 'Customer'

class ManageView(TemplateView):

  

      template_name = 'manage.html'

      context_object_name = 'form'

      

     @login_required(login_url='/manage/')

      def my_view(request):

         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 redirect('index.html' % request.path)         

                

            else:

              return HttpResponse("Your, Account is Disabled.")

         

      def logout_view(request):

         logout(request)

manage.html

{% block content %}

{% if form.errors %}

<p>Your username and password didn't match. Please try again.</p>

{% endif %}

<form method="post" action="{% url 'django.contrib.auth.views.login' %}">

{% csrf_token %}

<table>

<tr>

    <td>{{ form.username.label_tag }}</td>

    <td>{{ form.username }}</td>

    <td>{{ form.password.label_tag }}</td>

    <td>{{ form.password }}</td>

</tr>

</table>

<input type="submit" value="login" />

<input type="hidden" name="next" value="{{ next }}" />

</form>

{% endblock %}

index.html

{% load staticfiles %}

<link rel="stylesheet" type="text/css" href="{% static 'customer/style.css' %}" />

{% if Customer %}

    <ul>

    {% for Customer in Customer %}

      

       <li>{{ Customer.customer_name }}</li>

    {% endfor %}

    </ul>

{% else %}

    <p>No customers are available.</p>

{% endif %}

if i comment out the urls for #url(r'^$', views.IndexView.as_view(), name='index'), it will give me an error that it cant find /manage

Page not found (404)

Request Method:	GET
Request URL:	http://127.0.0.1:8000/

Using the URLconf defined in holon.urls, Django tried these URL patterns, in this order:

1. ^$ ^manage/$ [name='manage']
2. ^portal/
3. ^manage/$
4. ^admin/

The current URL, , didn't match any of these.

[C. Kirby]

You actually have a urls error.

Your first one: url(r'^', views.IndexView.as_view(), name='index'),
Should be: url(r'^$', views.IndexView.as_view(), name='index'),  (Note the $)

$ tells the url resolver to stop trying to match a url at the $. Since you don't have it, calls to manage/ match on the first url and never go through to match the second.

I chagned it further and it is still not working

        # combination is valid - a User object is returned if it is.

        user = authenticate(username=username, password=password)

        # with matching credentials was found.

            return HttpResponse("Invalid login details supplied.")

    # The request is not a HTTP POST, so display the login form.

    # This scenario would most likely be a HTTP GET.

Do you have APPEND_SLASH set in settings? If you don't and are trying to hit register instead of register/ it will fail

[C. Kirby]

According to the error, you didn't try to access /manage, just the root url
