Django 1.11 404 Page while Debug=True

Question

Without making things difficult, I just want to show a special 404 render with staticfiles.

If you set DEBUG = False you can use in urls.py

handler404 = 'app.views.handler404'

But it is without staticfiles. I don't want to install a web server for a simple app.

With DEBUG = True in urls

url(r'^404/$', views.handler400)

is not overriding the default Page not found (404) page.

What is the easy way to achieve a render e.g. when you type localhost/asdfhjfsda with staticfiles when DEBUG=True?

Thanks in advance...

Answer 1

In django 1.10 docs:

Changed in Django 1.9: The signature of page_not_found() changed. The function now accepts a second parameter, the exception that triggered the error. A useful representation of the exception is also passed in the template context.

Have a look at your 'app.views.handler404' definition, it might miss a parameter, and maybe it's that why the r'^404/$'handler doesn't provide you with the correct method invocation.

Answer 2

Easiest way to do this post Django 1.9 is in your urls.py:

from django.views.defaults import page_not_found

url(r'^404/$', page_not_found, {'exception': Exception()})

It wants an exception, give it an exception :)

I have a complete solution

My development environment: Windows 7, Python 3.5.2, Django 1.11, WAMP 3.0.6 (Apache 2.4.23, mod_wsgi)

1. Suppose you have error_404.html template with static files
2. Create next directory structure ("mysite" - Django project root folder)

mysite\
        mysite\
                settings.py
                urls.py
                views.py
        static\
                error404\
                          files\
                                 style.css 
                                 image.jpg
        templates\
                   error404\
                             error_404.html

3. mysite\mysite\settings.py

    import os

    DEBUG = False

    TEMPLATES = [{
        ..
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        ..
    }]

    STATIC_URL = '/static/'
    STATIC_ROOT = 'FullPathToYourSite.com/mysite/static/'

4. mysite\mysite\urls.py

    from django.conf.urls import handler404, handler500
    from . import views

    urlpatterns = [..]

    handler404 = views.error_404
    handler500 = views.error_404

5. mysite\mysite\views.py

    from django.shortcuts import render

    def error_404(request):
        return render(request, 'error404/error_404.html')

6. Some Jinjo logic in "error_404.html" (pseudocode)

    {% load staticfiles %}
    ...
      link type="text/css" href="{% static 'error404/files/style.css' %}"
    ...
      img src="{% static 'error404/files/image.jpg' %}"
    ...
