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 }}'>

When I paste the path to the image into the address bar it WILL cache the image and give me a 304... Here are those request and response headers:
