Django stores Amazon S3 giving 400 exceptions for bad request

Question

This is the first time I've contacted AWS S3 to store media. The application is hosted in Heroku, for static files this was not a problem, so I do not want to change static files, but I want application users to upload files and images that I want to save to S3. I have already spent 2-3 days so far and have not found the right solution, since I get an exception of 400 for no good reason. Here is the documentation I was talking about: http://tech.marksblogg.com/file-uploads-amazon-s3-django.html So, my settings are now:

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'

AWS_S3_ACCESS_KEY_ID='dummyid'
AWS_S3_SECRET_ACCESS_KEY='dummykey'
AWS_STORAGE_BUCKET_NAME='dummyname'
AWS_QUERYSTRING_AUTH = False
AWS_HEADERS = {'Cache-Control': 'max-age=86400', }
MEDIAFILES_LOCATION = 'media'
MEDIA_URL = 'http://%s.s3.amazonaws.com/media/' % AWS_STORAGE_BUCKET_NAME

My model:

class DummyDocuments(models.Model): document = models.FileField(upload_to='documents')

My form:

class DummyUploadForm(forms.Form): documents = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple': True}))

And here is the view in which I use it:

def upload(request):
    if request.method == 'POST':
        form = DummyUploadForm(request.POST, request.FILES)
        if form.is_valid():
            files = request.FILES.getlist('documents')
            for file in files:
                instance = DummyDocuments(document=file)
                instance.save()
            return redirect('activation_upload')
    else:
        form = DummyUploadForm()

    documents = DummyDocuments.objects.all()

    return render(request, 'activation/dummyupload.html', {'form': form, 'documents': documents})

Here is my CORS configuration on AWS:

<?xml version="1.0" encoding="UTF-8"?> <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <AllowedMethod>POST</AllowedMethod> <AllowedMethod>PUT</AllowedMethod> <AllowedHeader>*</AllowedHeader> </CORSRule> </CORSConfiguration>

Here is the exception I get:

May I find out what exactly is wrong?
