I have model UserProfile
with field avatar = models.ImageField(upload_to=upload_avatar)
upload_avatar
function names image file according user.id
(12.png for example).
But when user updates the avatar, new avatar name coincide with old avatar name and Django adds suffix to file name (12-1.png for example).
There are way to overwrite file instead of create new file?
Yeah, this has come up for me, too. Here's what I've done.
Model:
from app.storage import OverwriteStorage class Thing(models.Model): image = models.ImageField(max_length=SOME_CONST, storage=OverwriteStorage(), upload_to=image_path)
Also defined in models.py:
def image_path(instance, filename): return os.path.join('some_dir', str(instance.some_identifier), 'filename.ext')
In a separate file, storage.py:
from django.core.files.storage import FileSystemStorage from django.conf import settings import os class OverwriteStorage(FileSystemStorage): def get_available_name(self, name): """Returns a filename that's free on the target storage system, and available for new content to be written to. Found at http://djangosnippets.org/snippets/976/ This file storage solves overwrite on upload problem. Another proposed solution was to override the save method on the model like so (from https://code.djangoproject.com/ticket/11663): def save(self, *args, **kwargs): try: this = MyModelName.objects.get(id=self.id) if this.MyImageFieldName != self.MyImageFieldName: this.MyImageFieldName.delete() except: pass super(MyModelName, self).save(*args, **kwargs) """ # If the filename already exists, remove it as if it was a true file system if self.exists(name): os.remove(os.path.join(settings.MEDIA_ROOT, name)) return name
Obviously, these are sample values here, but overall this works well for me and this should be pretty straightforward to modify as necessary.
class OverwriteStorage(get_storage_class()): def _save(self, name, content): self.delete(name) return super(OverwriteStorage, self)._save(name, content) def get_available_name(self, name): return name
