Body
Your labels in the Document model is a M2M field, so that's going to end up rendering a multi-select in the rendered form (showing all the labels available in the system). Assuming that's what you want, in views.py <pre><code>def upload_document(request): if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) if form.is_valid(): labels = request.POST.getlist('labels') new_document = form.save() for label_id in labels: # we're only going to add currently defined labels label = Label.objects.get(id=int(label_id)) new_document.labels.add(label) new_document.save() return HttpResponseRedirect("/thanks/") else: form = DocumentForm() return render_to_response('doc_form.html', {'form':form}, context_instance=RequestContext(request)) </code></pre> I updated the model for Label in models.py, <pre><code>class Label(models.Model): name = models.CharField(max_length=40, unique=True) slug = models.SlugField(max_length=40, unique=True, editable=False) def save(self, *args, **kwargs): self.slug = slugify(self.name) super(Label, self).save(*args, **kwargs) def __unicode__(self): return self.name </code></pre> If you were thinking of having the user also create labels on the fly, you need to override the labels field in your form with something else, like an input field. As an example, if you're instructing the users to enter labels seperated by commas, then you'll have an updated views.py like, <pre><code>for label in labels: # labels entered by user try: lbl = Label.objects.get(name='label') except Label.DoesNotExist: lbl = None if not lbl: lbl = Label() lbl.name = label lbl.save() newDoc.labels.add(lbl) newDoc.save() </code></pre> Hope this solves your problem or give you something to work from.

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.
