Django Generic Views Customizing Generic Views
Example
The above example only works if your tasks are entirely standard tasks. You do not add extra context here, for example.
Let's make a more realistic example. Assume we want to add a page title to the template. In the functional view, this would work like this - with just one additional line:
def create_object(request):
page_title = 'My Page Title'
# ...
return render_to_response('template.html', locals())
This is more difficult (or: counter-intutitive) to achieve with generic views. As they are class-based, you need to override one or several of the class's method to achieve the desired outcome. In our example, we need to override the class's get_context_data method like so:
class CreateObject(CreateView):
model = SampleObject
form_class = SampleObjectForm
success_url = 'url_to_redirect_to'
def get_context_data(self, **kwargs):
# Call class's get_context_data method to retrieve context
context = super().get_context_data(**kwargs)
context['page_title'] = 'My page title'
return context
Here, we need four additional lines to code instead of just one - at least for the first additional context variable we want to add.
