Django class-based view: How do I pass additional parameters to the as_view method?


Question

I have a custom class-based view

# myapp/views.py
from django.views.generic import *

class MyView(DetailView):
    template_name = 'detail.html'
    model = MyModel

    def get_object(self, queryset=None):
        return queryset.get(slug=self.slug)

I want to pass in the slug parameter (or other parameters to the view) like this

MyView.as_view(slug='hello_world')

Do I need to override any methods to be able to do this?

Accepted Answer

Every parameter that's passed to the as_view method is an instance variable of the View class. That means to add slug as a parameter you have to create it as an instance variable in your sub-class:

# myapp/views.py
from django.views.generic import DetailView

class MyView(DetailView):
    template_name = 'detail.html'
    model = MyModel
    # additional parameters
    slug = None

    def get_object(self, queryset=None):
        return queryset.get(slug=self.slug)

That should make MyView.as_view(slug='hello_world') work.

If you're passing the variables through keywords, use what Mr Erikkson suggested: https://stackoverflow.com/a/11494666/9903

If your urlconf looks something like this:

url(r'^(?P<slug>[a-zA-Z0-9-]+)/$', MyView.as_view(), name = 'my_named_view')

then the slug will be available inside your view functions (such as 'get_queryset') like this:

self.kwargs['slug']
