copied!<p>I want to change my ImageField's attribute, however I'm constantly getting the Can't set attribute error.</p> <p>My model is </p> <pre><code>class Society(models.Model): name = models.CharField(max_length=200) slug = models.SlugField(unique=True) summary = models.TextField(blank=True,null=True) members = models.ManyToManyField(User,null=True,blank=True) gallery = models.ForeignKey(Gallery,null=True,blank=True) avatar = models.ImageField(upload_to=get_society_path) def save(self,*args,**kwargs): super(Society, self).save(*args,**kwargs) fix_avatar_path(self) def clean(self): if self.id: self.avatar.path = get_society_path(self,self.avatar.path) save_thumb(self.avatar.path) </code></pre> <p>And my helper functions are :</p> <pre><code>def get_society_path(instance,filename): seperator_val = instance.id if seperator_val is None: seperator_val = get_time() return '%s/society_%s/%s' % (settings.UPLOAD_ROOT,seperator_val,time_to_name(filename)) def fix_avatar_path(instance): org_society_path = get_society_path(instance,instance.avatar.name) make_upload_dir(org_society_path) move(instance.avatar.path,org_society_path) os.rmdir(os.path.dirname(instance.avatar.path)) instance.clean() </code></pre> <p>The problem is :</p> <p>I want to save my society directories as society_society_id. But normally, I can't assign any id before the model is saved. So i'm creating a tmp file whose name is a time value.Then to reach societies folder, I want to rename this file. So, my fix_avatar simply moves the tmp file's content to society_(society_id) folder after the society is saved. So far so good everything works well. However, my society's ImageField still holds the previously created folder. In order to change it's value, I found that i can use clean method.(from this <a href="https://stackoverflow.com/questions/4583090/django-changing-the-url-of-an-optional-imagefield">SO question</a>) But still i'm getting the same result, the path doesn't change, and gives the "can't set attribute" response. </p> <p>Any idea ??</p>
