If I add a save(), it seems to work:
class HeaderImage(models.Model):
"""
A HeaderImage of an Article.
"""
picture = models.ImageField(null=True, upload_to='./
images/',core=True)
item = models.ForeignKey(Article, edit_inline=models.TABULAR,
max_num_in_admin=1)
remove = models.BooleanField(default=False)
def __unicode__(self):
return self.picture
def save(self):
super(CategoryImage,self).save()
if self.remove:
self.delete()
def delete(self):
if not self.picture==None and not self.picture=='':
basename, format = self.picture.rsplit('.', 1)
miniature_folder = os.path.join(s.MEDIA_ROOT, basename
+'/')
if os.path.exists(miniature_folder):
dir = os.getcwd()
os.chdir(miniature_folder)
listdir=os.listdir(miniature_folder)
for i in listdir:
os.remove(i)
os.chdir(dir)
os.removedirs(miniature_folder)
super(HeaderImage,self).delete()
