display a pretty pagebar by using templatetag, and supply an optional customize Paginator based on official paginator.

django official display all pages by paginator and page_obj, like this:

[1] [2] [3] [4] [5] [6] [7] [...] [195] [196] [197] [198] [199] [200] # total 200 pages for example.

use this code:

{% for page_number in paginator.page_range %}
    <a href='?page={{page_number}}>{{page_number}}</a>
{% endfor %}

ugly display all the pages of 200, even if you have 2000 pages, it will display 2000 links on one page.

so, the problem is the paginator.page_range, if we can modify the paginator.page_range, the problem will fix.

so, my solution is modify the page_range, to display a part of origin page_range, just called slicing and some if else control.

for example, 200 pages, cur_page is var, it will display as follows:

[] and {} is for styling. {} is cur_page, [] is pages.

cur_page = 1

{1} [2] [3] [4] [...200] [Next]

cur_page = 2

[Previous] [1] {2} [3] [4] [5] [...200] [Next]

cur_page = 3

[Previous] [1] [2] {3} [4] [5] [6] [...200] [Next]

cur_page = 4

[Previous] [1] [2] [3] {4} [5] [6] [7] [...200] [Next]

cur_page = 5

[Previous] [1...] [2] [3] [4] {5} [6] [7] [8] [...200] [Next]

cur_page = 6

[Previous] [1...] [3] [4] [5] {6} [7] [8] [9] [...200] [Next]

cur_page = x > 4, x <= 200-4

[Previous] [1...] [x-3] [x-2] [x-1] {x} [x+1] [x+2] [x+3] [...200] [Next]

cur_page = 196

[Previous] [1...] [193] [194] [195] {196} [197] [198] [199] [...200] [Next]

cur_page = 197

[Previous] [1...] [194] [195] [196] {197} [198] [199] [200] [Next]

cur_page = 198

[Previous] [1...] [195] [196] [197] {198} [199] [200][Next]

cur_page = 199

[Previous] [1...] [196] [197] [198] {199} [200] [Next]

cur_page = 200

[Previous] [1...] [197] [198] [199] [200]

that is much more pretty than the origin pagebar display.

must use django1.4 or higher, to use more powerful {% if ...%} tag.

if you want use pagebar, do as follow:

• put the pagebar_tags.py in your appname/templatetags
• copy the news_pagebar.html to your templates/appname/appname_pagebar.html , just for rename,or keep same.
• see pagebar_tags.py , news_pagebar.html, news_list.html for more detail usage.
• any quetion, plz goto issues.-

it's very simple to use!
