Hi community I have two models in two apps, first named newsItem
from django.db import models from datetime import datetime class newsItem(models.Model): pubDate = models.DateTimeField('date published',default=datetime.now()) author = models.CharField(max_length=20, default="author") title = models.CharField(max_length=200) text = models.TextField() snippet = models.TextField(blank=True) tags = models.ManyToManyField('newsTag', through='TagsToNews') needsGallery = models.BooleanField() def __unicode__(self): return self.title def save(self, *args, **kwargs): if len(unicode.strip(self.snippet)) == 0: self.snippet = "" super(newsItem, self).save(*args, **kwargs) and second one in another app called subGallery, which is related to newsItem via foreign key from django.db import models from news.models import newsItem, newsTag class subGallery(models.Model): pubDate = models.DateTimeField('date published') title = models.CharField(max_length=200) text = models.TextField(blank=True) tags = models.ManyToManyField(newsTag, through='TagsToGalleries') newsItem = models.ForeignKey('news.newsItem') def __unicode__(self): return self.title class Meta: verbose_name_plural = "Galleries" What I want to do is to create new subGallery whenever newsItem with "needGallery" field set to true gets created or saved, so I altered save method of newsItem like this: def save(self, *args, **kwargs): if len(unicode.strip(self.snippet)) == 0: self.snippet = "" super(newsItem, self).save(*args, **kwargs) if self.needsGallery: if not(len(self.subGallery_set.all())): gallery = subGallery(title = self.title, pubDate=self.pubDate) gallery.save() but when I am creating newsItem through admin page it says: 'newsItem' object has no attribute 'subGallery_set' What am I doing wrong? -- You received this message because you are subscribed to the Google Groups "Django users" group.
