Django 分页功能

Django 分页功能比较强大，这边是结合官网的内容写的可以参考

https://docs.djangoproject.com/en/1.9/topics/pagination/

>>> from django.core.paginator import Paginator

>>> objects = ['john', 'paul', 'george', 'ringo']

>>> p = Paginator(objects, 2)

 

>>> p.count

4

>>> p.num_pages

2

>>> type(p.page_range)  # `<type 'rangeiterator'>` in Python 2.

<class 'range_iterator'>

>>> p.page_range

range(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 page

3

>>> page2.end_index() # The 1-based index of the last item on this page

4

 

>>> 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
