Body
copied!<p>I'm creating a simple CMS in django, with multiple "modules" (each as a django app). I've set up the following models:</p> <pre><code>class FooObject(models.Model): id = models.SlugField(primary_key=True) name = models.CharField(max_length=255) creator = models.ForeignKey(auth.models.User, editable=False, related_name="createdby") class FooPage(FooObject): content = models.TextField(blank=True, null=True) @models.permalink def get_absolute_url(self): return ('page', (), {'page_id':self.id} class FooSubitem(FooObject): parent = models.ForeignKey(FooPage, related_name='subitems') </code></pre> <p>In each of the modules, I create a subclass of FooPage, and at least one subclass of FooSubitem, e.g.</p> <pre><code># in FooBlog.models class FooBlog(FooPage): owner = models.ForeignKey(auth.models.User, editable=False) @models.permalink def get_absolute_url(self): return ('blog', (), {'blog_id':self.id}) class FooPost(FooSubitem): post_time = models.DateTimeField(auto_now_add=True) </code></pre> <p>and</p> <pre><code># in FooGallery.models class FooGallery(FooPage): location = models.CharField(max_length=255) @models.permalink def get_absolute_url(self): return ('gallery', (), {'gallery_id':self.id}) class FooImage(FooSubitem): image_file = models.ImageField(upload_to='foogallery') </code></pre> <p>These are simplifications, but should give you a good idea of what I'm trying to do. In the admins for FooPost and FooImage, I restrict the parent selection list to their corresponding parent pages.</p> <p>My problem arises when I try to use these in a template. In each view, I have the following:</p> <pre><code>page_list = FooPage.objects.all() </code></pre> <p>which returns a list of all FooPages, of both FooBlog and FooGallery types. However, when I iterate through this list:</p> <pre><code>{% for page in page_list %}{{ page.get_absolute_url }}{% endfor %} </code></pre> <p>it returns the 'page' url pattern, not the 'blog' or 'gallery' url pattern.</p> <p>How do I make this work without having to rewrite the code when I want to add a FooCalendar module later on? I want to make sure this works with any possible module.</p> <p>Thanks,</p> <ul> <li>Lexo</li> </ul>
