Question

I have this model

class messages(models.Model):
    status_choices = (
        (u'read',u'read'),
        (u'unread',u'unread')
        )
    user = models.ForeignKey(User)
    message = models.TextField()
    status = models.CharField(max_length=6,choices=status_choices,default='unread')
    sender = models.ForeignKey(User,related_name="sender")

Now I want to fetch only first 10 messages that belong “user1”,on the second request next 10 messages and so on.How can I do that?

Answer 1

Django provides this functionality already with a Paginator object. In your URL you’ll need a page parameter that says on which page you are and in your view you need to construct a Paginator object. You need to specify the number of objects on a page (in your case 10) and the Paginator will do the rest.

For example, the following code will print all instances that are displayed on page 3:

from django.core.paginator import Paginator

objects = messages.objects.all()
p = Paginator(objects, 10)
page3 = p.page(3)
print page3.object_list

The documentation gives examples on how to implement your views and how to pass the list of objects to your template.
