I am using the s3boto backend, not the s3 backend.

In the django-storages docs it says to specify the AWS_HEADERS variable on your settings.py file:

AWS_HEADERS (optional)

If you’d like to set headers sent with each file of the storage:

# see http://developer.yahoo.com/performance/rules.html#expires

AWS_HEADERS = {

'Expires': 'Thu, 15 Apr 2010 20:00:00 GMT',

'Cache-Control': 'max-age=86400',

}

This is not working for me.

Here is my model:

class Photo(models.Model):

    """

        docstring for Photo

        represents a single photo.. a photo can have many things associated to it like

        a project, a portfolio, etc...

    """

    def image_upload_to(instance, filename):

        today = datetime.datetime.today()

        return 'user_uploads/%s/%s/%s/%s/%s/%s/original/%s' % (instance.owner.username, today.year, today.month, today.day, today.hour, today.minute, filename)

    def thumb_upload_to(instance, filename):

        today = datetime.datetime.today()

        return 'user_uploads/%s/%s/%s/%s/%s/%s/thumb/%s' % (instance.owner.username, today.year, today.month, today.day, today.hour, today.minute, filename)

    def medium_upload_to(instance, filename):

        today = datetime.datetime.today()

        return 'user_uploads/%s/%s/%s/%s/%s/%s/medium/%s' % (instance.owner.username, today.year, today.month, today.day, today.hour, today.minute, filename)

    owner = models.ForeignKey(User)

    # take out soon

    projects = models.ManyToManyField('Project', through='Connection', blank=True)

    image = models.ImageField(upload_to=image_upload_to)

    thumb = ThumbnailerImageField(upload_to=thumb_upload_to, resize_source=dict(size=(102,102), crop='center'),)

    medium = ThumbnailerImageField(upload_to=medium_upload_to, resize_source=dict(size=(700,525),))

    title = models.CharField(blank=True, max_length=300)

    caption = models.TextField(blank=True)

    can_view_full_res = models.BooleanField(default=False)

    is_portfolio = models.BooleanField(default=False)

    created_time = models.DateTimeField(blank=False, auto_now_add=True)

    disabled = models.DateTimeField(blank=True, null=True, auto_now_add=False)

    cost = models.FloatField(default=0)

    rating = models.IntegerField(default=0)

    mature_content = models.BooleanField(default=False)

    objects = ViewableManager()

    def get_absolute_url(self):

        return "/m/photo/%i/" % self.pk

    def get_prev_by_time(self):

        get_prev = Photo.objects.order_by('-created_time').filter(created_time__lt=self.created_time)

        try:

            return get_prev[0]

        except IndexError:

            return None

    def get_next_by_time(self):

        get_next = Photo.objects.order_by('created_time').filter(created_time__gt=self.created_time)

        try:

            return get_next[0]

        except IndexError:

            return None

    def __unicode__(self):

        return(self.title)

This is what is on my template where I have the image...

<img class='shadow' src='{{ object.medium.url }}'>
