What's the best way to rename photos with a unique filename on the server as they are uploaded, using django? I want to make sure each name is used only once. Are there any pinax apps that can do this, perhaps with GUID?
Use uuid. To tie that into your model see Django documentation for FileField upload_to.
For example in your models.py define the following function:
import uuid import os def get_file_path(instance, filename): ext = filename.split('.')[-1] filename = "%s.%s" % (uuid.uuid4(), ext) return os.path.join('uploads/logos', filename)
Then, when defining your FileField/ImageField, specify
get_file_path as the
file = models.FileField(upload_to=get_file_path, null=True, blank=True, verbose_name=_(u'Contact list'))
