Django中使用Pagination的分页范例源码

将做工程过程重要的内容做个珍藏，下面代码内容是关于Django中使用Pagination的分页范例的代码。

>> from django.core.paginator import Paginator
>> objects = ['john', 'paul', 'george', 'ringo']
>> p = Paginator(objects, 2)

>> p.count
4
>> p.num_pages
2
>> p.page_range
[1, 2]

>> 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
