I'm having an odd problem when trying to import some python modules in my Django models. Things just aren't working how I'd expect:
The broken model is below. The problem occurs when _post_save is called, it will error out on the "thumbs_dir = os.path..." line because it says that "os" is not globally defined. This doesn't seem to jive with all my other python experience. If I import the module at the top of my file, I should be able to use it all over the place. To fix the problem, I can move the "from django.conf.settings import MEDIA_ROOT
import os.path
import Image" inside the _post_save(self) method. Any ideas why my conventional python wisdom is failing me here?
### Begin Broken Links Model ###
from django.core import meta
from django.conf.settings import MEDIA_ROOT
import os.path
import Image
class Link(meta.Model):
uri = meta.URLField()
link_name = meta.CharField(maxlength=255)
source_name = meta.CharField(maxlength=255)
clicks = meta.IntegerField(default=0)
pub_date = meta.DateTimeField()
thumbnail = meta.ImageField(upload_to="uploads")
approved = meta.BooleanField(default=False)
def __repr__(self):
return self.uri
def _post_save(self):
size = 100, 150
thumbs_dir = os.path.dirname(self.get_thumbnail_filename()) + "/thumbnails/"
thumbsfile = thumbs_dir + "tn_" + os.path.basename(self.get_thumbnail_filename())
infile = self.get_thumbnail_filename()
outfile = thumbsfile
im = Image.open(infile)
im.thumbnail(size)
im.save(outfile,quality=100)
class META:
admin = meta.Admin()
def get_thumb_url(self):
import os.path
tnd = "/thumbnails/"
tnp = "tn_"
fs = self.get_thumbnail_url ()
return os.path.dirname(fs) + tnd + tnp + os.path.basename(fs)
### End Broken Links Model ###
Thanks,Clint
