If you have a category instance in template: <pre><code>category.entry.all -> list of entries </code></pre> If you have an entry instance in template: <pre><code>entry.category_entry.all -> list of categories </code></pre> You should call M2M fields in plural form, then you will have a more readable code <pre><code>category.entries.all </code></pre> %model%_set syntax (or related name, if you've specified it) is using to access to model trough a backward relationship. <a href="https://docs.djangoproject.com/en/1.4/topics/db/queries/#following-relationships-backward" rel="nofollow">https://docs.djangoproject.com/en/1.4/topics/db/queries/#following-relationships-backward</a> But how do I get the 'votes' associated with the m2m instance? – Bryce I suggest you the following way: <pre><code>class Category(models.Model): title = models.CharField(max_length=1024,null=True,blank=True) entries = models.ManyToManyField(Entry,null=True,blank=True, related_name='categories', through='CategoryEntry', ) class CategoryEntry(models.Model): category = models.ForeignKey(Category, related_name='category_entries') entry = models.ForeignKey(Entry) votes = models.IntegerField(null=False, default=0) def category_detail(request, pk): category = models.Category.objects.select_related().get(pk=pk) category_entries = category.category_entries.filter(entry__temp_sort_order__gte=0).order_by('-entry__temp_sort_order') for category_entry in category_entries: # category_entry is an instance of the model CategoryEntry pprint('category entry votes: ' + str(category_entry.votes)) pprint('entry title: ' + category_entry.entry.title) .... HOW TO entry = Entry.objects.get(pk=1) entry.categories.all() # list of categories (here we work through related name of the field entries) category = Category.objects.get(pk=1) category.entries.all() # list of entries (here we work through m2m field entries) category.category_entries.all() # list of CategoryEntry objects (through related name category_entries of the field category in model CategoryEntry) </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
