Useful shortcuts

1. render, since Django 1.3.

• render() is the same as a call to render_to_response() with a context_instance argument that forces the use of a RequestContext.

2. redirect, since Django 1.1, usage:

• redirects to:
• 1. an object, with defined get_absolute_url
• 2. a named url
• 3. a hardcoded url (relative or full)

in views.py

from django.shortcuts import render
return render(request, 'my_template.html', context)

from django.shortcuts import redirect
return redirect('name_of_url')

Use named urls

models.py:

class Car(models.Model):
    ...

    def get_absolute_url():
        return reverse('car')

urls.py

url(r'/(\d+)/', 'car.views.car', name='car')

views.py

return redirect('car', car.id)

in cars.html template:

{% for car in cars %}
    <a href="{{ car.get_absolute_url }}">car.name</a>
{% endfor %}
