I'm using ListView in my Class Based Views and I was wondering if there was a way to display the model object set on the template by sorting it. This is what I have so far:
My views:
class Reviews(ListView):
model = ProductReview
paginate_by = 50
template_name = 'review_system/reviews.html'
The model ProductReview has a date_created field. I'd like to sort the date in descending order. How can I achieve this?
Set the ordering attribute for the view.
class Reviews(ListView):
model = ProductReview
paginate_by = 50
template_name = 'review_system/reviews.html'
ordering = ['-date_created']
If you need to change the ordering dynamically, you can use get_ordering instead.
class Reviews(ListView):
...
def get_ordering(self):
ordering = self.request.GET.get('ordering', '-date_created')
# validate ordering here
return ordering
If you are always sorting a fixed date field, you may be interested in the ArchiveIndexView.
from django.views.generic.dates import ArchiveIndexView
class Reviews(ArchiveIndexView):
model = ProductReview
paginate_by = 50
template_name = 'review_system/reviews.html'
date_field = "date_created"
Note that ArchiveIndexView won't show objects with a date in the future unless you set allow_future to True.
Why don't you override the get_queryset method like this:
class Reviews(ListView):
model = ProductReview
paginate_by = 50
template_name = 'review_system/reviews.html'
def get_queryset(self):
return YourModel.objects.order_by('model_field_here')
