below is the code... the first def doesn't return anything... (def
get_gal_teaser(self))
i'm using a custom tag to return the Gallery class to the base
template file, which works... so calling the method get_gal_teaser
works as well... and returns an object? when the second e =
e.image.get_thumbnail_url() is not there... ie this is returned:
[<ImageUpload: image 1>]
i want to return, obviously from above, the get_thumbnail url method
so i can work with html/css to display it nicely in a secondary nav
class Gallery(models.Model):
name = models.CharField(max_length=200)
descrip = models.TextField()
gallery_id = models.AutoField(primary_key=True)
def get_gal_teaser(self):
e = ImageUpload.objects.filter(gallery = self.gallery_id)[:1]
e = e.image.get_thumbnail_url()
return e
def __unicode__(self):
return u'%s ' %(self.name)
class ImageUpload(models.Model):
title = models.CharField(max_length=200)
image = models.ImageField(upload_to = 'gallery')
gallery = models.ForeignKey('Gallery')
def save(self):
super(ImageUpload, self).save()
if self.image:
tsize = 150,150
path = settings.MEDIA_ROOT + self.image.name
img2 = Image.open(path)
img2.thumbnail(tsize, Image.ANTIALIAS)
img2.save(self.get_thumbnail_path())
def get_thumbnail_path(self):
path = settings.MEDIA_ROOT + self.image.name
return self.convert_path_to_thumbnail(path)
def convert_path_to_thumbnail(self, path):
basedir = os.path.dirname(path) + '/'
base, ext = os.path.splitext(os.path.basename(path))
th_name = base + "_tn"
th_name += ext
return urlparse.urljoin(basedir,th_name)
def get_thumbnail_url(self):
path = settings.MEDIA_ROOT + self.image.name
