a StringIO like class, that extends django.core.files.File

Question

class MyModel(models.Model)
 image = models.FileField(upload_to="blagh blagh...")

I have a file in memory and I want to save it via Django FileField save method, like this:

photo.image.save(name, buffer) # second arg should be django File

I've tried to use StringIO, but it doesn't extend django.core.files.File and thus doesn't implement method chunks(). I've wrapped it in a File object like that:

buffile = File(buffer, name) # first argument should be a file
photo.image.save(name, buffile)

But File methods use size and name fields of supplied file. StringIO doesn't define them. I've found this, but the link is dead

Answer 1

You can use ContentFile instead of File

from django.core.files.base import ContentFile

photo.image.save(name, ContentFile(buffer))
