问题描述
我正在Django中创建一个SlugField。我创建了这个简单的模型:
from django.db import models
class Test(models.Model):
q = models.CharField(max_length = 30)
s = models。 SlugField()
然后我这样做:
>>>来自mysite.books.models import Test
>>> t = Test(q =aa a a a,s =b b b b)
>>> t.s
'b b b b'
>>>> t.save()
>>> t.s
'b b b b'
>>>>
我期待bbbb
解决方案
您将需要使用slugify功能。
>>>来自django.template.defaultfilters import slugify
>>> slugify(b b b b)
u'b-b-b-b'
>>>
您可以自动调用 slugify
保存
方法:
类测试(models.Model):
q = models.CharField(max_length = 30)
s = models.SlugField()
def save(self,* args,** kwargs):
self.s = slugify(self.q)
super(test,self).save(* args,** kwargs)
请注意,当编辑 q
字段时,上述将导致您的URL更改,其中。创建新对象时,最好只生成一次块:
class test(models.Model):
q = models.CharField(max_length = 30)
s = models.SlugField()
def save(self,* args,** kwargs):
如果不是自己.id:
#新建的对象,所以设置slug
self.s = slugify(self.q)
super(test,self).save(* args,* * kwargs)
I am trying to create a SlugField in Django.
I created this simple model:
from django.db import models
class Test(models.Model):
q = models.CharField(max_length=30)
s = models.SlugField()
I then do this:
>>> from mysite.books.models import Test
>>> t=Test(q="aa a a a", s="b b b b")
>>> t.s
'b b b b'
>>> t.save()
>>> t.s
'b b b b'
>>>
I was expecting b-b-b-b
解决方案
You will need to use the slugify function.
>>> from django.template.defaultfilters import slugify
>>> slugify("b b b b")
u'b-b-b-b'
>>>
You can call slugify
automatically by overriding the save
method:
class test(models.Model):
q = models.CharField(max_length=30)
s = models.SlugField()
def save(self, *args, **kwargs):
self.s = slugify(self.q)
super(test, self).save(*args, **kwargs)
Be aware that the above will cause your URL to change when the q
field is edited, which can cause broken links. It may be preferable to generate the slug only once when you create a new object:
class test(models.Model):
q = models.CharField(max_length=30)
s = models.SlugField()
def save(self, *args, **kwargs):
if not self.id:
# Newly created object, so set slug
self.s = slugify(self.q)
super(test, self).save(*args, **kwargs)
