[Fixed]-How to mix Django, Uploadify, and S3Boto Storage Backend?

Use a URLField.

I had a similar issue where i want to store file to s3 either directly using FileField or i have an option for the user to input the url directly. So to circumvent that, i used 2 fields in my model, one for FileField and one for URLField. And in the template i could use ‘or’ to see which one exists and to use that like {{ instance.filefield or instance.url }}.

This is untested, but you should be able to use:

from django.core.files.storage import default_storage
f = default_storage.open('name_you_expect_in_s3', 'r')
#f is an instance of S3BotoStorageFile, and can be assigned to a field
obj, created = YourObject.objects.get_or_create(**stuff_you_know)
obj.s3file_field = f
obj.save()

I think this should set up the local pointer to s3 and save it, without over writing the content.

ETA: You should do this only after the upload completes on S3 and you know the key in s3.

Checkout django-filetransfers. Looks like it plays nice with django-storages.

I’ve never used django, so ymmv 🙂 but why not just write a single byte to populate the content? That way, you can still use FieldFile.

I’m thinking that writing actual SQL may be the easiest solution here. Alternatively you could subclass S3BotoStorage, override the _save method and allow for an optional kwarg of filepath which sidesteps all the other saving stuff and just returns the cleaned_name.
