how can i access ForeignKey model attribute value in save() or
__unicode__ method?
some hint will help.
here is my model.py:
class PhotoSetPhotoItem(models.Model):
photo_item = models.ForeignKey('Photo', related_name='photoitem')
slug = models.SlugField(blank = True, null = True)
def __unicode__(self):
# ----> BELOW IS THE PROBLEMATIC PART
return str(self.photo_set)+str(self.photo_item)+str
(self.photo_item.img)
def save(self, force_insert=False, force_update=False):
if self.photo_item != None:
# ----> BELOW IS THE PROBLEMATIC PART
self.slug = str(self.photo_set)+str(self.photo_item)+str
(self.photo_item.img)
super(PhotoSetPhotoItem, self).save(force_insert,
force_update)
class Photo(models.Model):
title_hr = models.CharField('(hr)', max_length=255)
slug = models.SlugField()
img = FileBrowseField(max_length=200, initial_directory="", ...)
def __unicode__(self):
return self.title_hr
def getImg(self):
return self.img
tnx!
