Creating a list off a model based on time delta

[Conner DiPaolo]

Hi!

I was wondering if anybody knew how to create a list based on that list having a DateTime attribute that is less than 30 days old. I already have a boolean in the model itself of 'published_recent_month' that can say if it is or is not published within a month, but how do I put into that a list to put into a template? I know how to do a list based on pub_date and have it be a certain length, but I would rather have the list be dynamic to usage.

Thanks a lot!

abbreviated model to show the boolean definition I have:

class Model(models.Model):
   ...
   def published_recent_month(self):

return self.pub_date >= timezone.localtime(timezone.now()) - datetime.timedelta(days=30)

abbreviated  view using what I already know:

def index(request):
   ...
   latest_25_list =Model.objects.order_by('-pub_date')[:25]

I've been thinking about it and I think this should work but it doesn't.

latest_articles_list = Article.objects.filter(pub_date>=thirty_days_ago)

Django is saying 'pub_date' is not defined, even though I used it to filter a different list and it worked fine. What is wrong??

Thanks

Use __gte lookup:

latest_articles_list = Article.objects.filter(pub_date__gte=thirty_days_ago)

and take a look at other lookups:
