https://docs.djangoproject.com/en/1.9/topics/pagination/
分页命令行练习案列
>>> from django.core.paginator import Paginator>>> objects = [‘john‘, ‘paul‘, ‘george‘, ‘ringo‘]>>> p = Paginator(objects, 2)>>> p.count4>>> p.num_pages2>>> type(p.page_range) # `<type ‘rangeiterator‘>` in Python 2.<class ‘range_iterator‘>>>> p.page_rangerange(1, 3)>>> page1 = p.page(1)>>> page1<Page 1 of 2>>>> page1.object_list[‘john‘, ‘paul‘]>>> page2 = p.page(2)>>> page2.object_list[‘george‘, ‘ringo‘]>>> page2.has_next()False>>> page2.has_previous()True>>> page2.has_other_pages()True>>> page2.next_page_number()Traceback (most recent call last):...EmptyPage: That page contains no results>>> page2.previous_page_number()1>>> page2.start_index() # The 1-based index of the first item on this page3>>> page2.end_index() # The 1-based index of the last item on this page4>>> p.page(0)Traceback (most recent call last):...EmptyPage: That page number is less than 1>>> p.page(3)Traceback (most recent call last):...EmptyPage: That page contains no results
