python - Saving Image to Django, the correct way ? -


what best practice set upload path in django 1.4? have model 

def upload_image(instance, filename):      return os.path.join(instance.slug, filename)  class book(models.model):     ...     ...      image = models.imagefield(upload_to=upload_image)       def admin_image(self):         return "<img src='%s' />" % self.image      ....

with settings.py

project_dir = os.path.dirname(os.path.realpath(__file__)) root_dir = project_dir.rsplit(os.sep, 1)[0]  media_root = os.path.join(root_dir, 'books', 'static', 'books') media_url = '/media/'  static_root = '' static_url = '/static/'

and admin.py 

class bookadmin(admin.modeladmin):     list_display = ('title', 'admin_image')

so, in end, got image correctly saved /root-of-project/books/static/books/programming-java/wall.jpg, however, saved path in database "programming-java/wall.jpg" , have concat prefix '/static/books/' everytime displaying image

why concat/hardcode lines in templates? can use static tag purpose

{% load staticfiles %} <img src="{% static "images/hi.jpg" %}" />

alias

{% load staticfiles %} <img src="{% static object.image.url %}" />

and if must, can add method model you?
