python - Create Django slug method -

i started using django time , stuck trying work slug. know are, it's dificult me define simple slug , display on browser.

here scenario: i've models.py containing class book 3 fields: name, price , autor. want retunr slug string name , autor hyphens (-) , lowercase letters.

my question how achieve this. using model, views , html. i've got till now. don't know how displayed on browser(localhost:8000/book_name)

class book(models.model):     name = models.charfield(max_length=100)     price = models.integerfield(default=0)     autor = models.charfield(max_length=100)      slug = models.slugfield(unique=true)      @models.permalink     def get_absolute_url(self):         return 'app:book', (self.slug,) 

from django.template.defaultfilters import slugify 

add following model:

def save(self,*args,**kwargs):    self.slug = slugify(self.name)   return super(book,self).save(*args,**kwargs) 

then can use slug in urls:

url(r'mybooks/(?p<slug>[-\w]+)/$', views.bookdetailview.as_view(),name='book_details'), 

views:

from django.views import generic  class bookdetailview(generic.detailview):     template_name = "templates/book_detail.html"
