Hi, any idea how to construct my get_absolute_url
(127.0.0.1:8000/category-slug/id-slug-post
<http://127.0.0.1:8000/category-slug/id-slug-post>)
for example i have my models like this
class Category(...):
name = CharField(....)
slug = SlugField(.....)
class MyModel(modesl.Model):
post = models.CharField(....)
slug = models.SlugField(.....)
categories = models.ManyToMany(Category)
def get_absolute_url(self):
return "/%s/%s-%s/" % (self.categories.slug, self.id
<http://self.id>, self.slug)
#error 'ManyRelatedManager' object has no attribute 'slug'
in self.categories.slug
https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.ManyToManyField
https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.ManyToManyField.through
The "through" table doesn't need a coded Django model if it is only used
to relate the two different tables in the m2m relationship. However, if
you want to include other data - such as a slug - then you need to code
it explicitly.
The "through" table will already exist in your database so choose the
same name for the model as you see there. It will only have two foreign
key fields, one to each of the related tables after which it is named.
Once you have a model with the two FKs and your slug,
makemigrations/migrate will adjust it to include the slug.
i would like this url in my page
127.0.0.1:8000/category-slug/id-slug-post
<http://127.0.0.1:8000/category-slug/id-slug-post>
example
http://mydomain.com/food-green/120-one-hundry-food-green
domain.com <http://domain.com> / category slug / pk - (dash) post slug
the problems is for my get_absolute_url see, one post have multiple
category
the error is:
'ManyRelatedManager' object has no attribute 'slug'
what is the best way to do this?
any idea?
Cheers
