PS:好吧，我真的不想发表文章，为什么呢？因为我是一个菜鸡，特别菜的那种，笔记，脑图一大堆，但是仍然菜的一匹，唉，不说了......
首先吧，学习Django第一个遇上的坑——slug字段，为啥呢？这货不懂中文.....
一、介绍：
django-uuslug是一个很方便的将中文转化成拼音slug的插件. 通过使用django-uuslug, 可以保确保slug是唯一的, 并且都是unicode编码的。
二、安装：
pip install django-uuslug
三、使用：
重写model.py中的save()方法:
from django.db import models
from uuslug import uuslug
class CoolSlug(models.Model):
name = models.CharField(max_length=100)
slug = models.CharField(max_length=200)
def __unicode__(self):
return self.name
def save(self, *args, **kwargs):
# self.slug = uuslug(self.name, instance=self, separator="_")
# optional non-dash separator
self.slug = uuslug(self.name, instance=self, start_no=2)
super(CoolSlug, self).save(*args, **kwargs)
默认：
去首尾符号
多个中划线变成一个
中文翻译成拼音用"-"隔开
separator 指定隔开字符：
separator="字符"
start_no 指定起始数字：
start_no=数字
max_length 限制slug的长短：
max_length=数字
word_boundary 字边界：配合mex_length在保存单词完整性下，保证slug的限制长短
word_boundary=True
save_order 保存顺序？：配合mex_length和word_boundary来保证字符长短，完整性下的顺序。（我TM在讲什么？）即在前两者满足情况下，如果save_order为false，在长度不够的情况下，可能会选择后面较短的字符。
save_order=True
过滤某些字符，接收参数为一个数组。该方法大小写不灵敏。
stopwords=['字符', '字符']
Django外使用
这个我直接copy的geihub
