    <p>This is one solution, though not the option i really wanted to use. You can do it by overriding the the whole <strong>add_view</strong> function and setting the intial attributes for each form in the formsets (look for the override comment below)</p> <pre><code>def add_view(self, request, form_url='', extra_context=None): "The 'add' admin view for this model." model = self.model opts = model._meta if not self.has_add_permission(request): raise PermissionDenied ModelForm = self.get_form(request) formsets = [] if request.method == 'POST': form = ModelForm(request.POST, request.FILES) if form.is_valid(): new_object = self.save_form(request, form, change=False) form_validated = True else: form_validated = False new_object = self.model() prefixes = {} for FormSet, inline in zip(self.get_formsets(request), self.inline_instances): prefix = FormSet.get_default_prefix() prefixes[prefix] = prefixes.get(prefix, 0) + 1 if prefixes[prefix] != 1: prefix = "%s-%s" % (prefix, prefixes[prefix]) formset = FormSet(data=request.POST, files=request.FILES, instance=new_object, save_as_new="_saveasnew" in request.POST, prefix=prefix, queryset=inline.queryset(request)) formsets.append(formset) if all_valid(formsets) and form_validated: self.save_model(request, new_object, form, change=False) form.save_m2m() for formset in formsets: self.save_formset(request, form, formset, change=False) self.log_addition(request, new_object) return self.response_add(request, new_object) else: # Prepare the dict of initial data from the request. # We have to special-case M2Ms as a list of comma-separated PKs. initial = dict(request.GET.items()) for k in initial: logger.info( "for k in initial, k = %s" % k ) try: f = opts.get_field(k) except models.FieldDoesNotExist: continue if isinstance(f, models.ManyToManyField): initial[k] = initial[k].split(",") form = ModelForm(initial=initial) prefixes = {} for FormSet, inline in zip(self.get_formsets(request), self.inline_instances): prefix = FormSet.get_default_prefix() prefixes[prefix] = prefixes.get(prefix, 0) + 1 if prefixes[prefix] != 1: prefix = "%s-%s" % (prefix, prefixes[prefix]) formset = FormSet(instance=self.model(), prefix=prefix, queryset=inline.queryset(request)) # # # override the inlines of my choice # to create initial values # # if inline.__class__.__name__ == 'ResourceCategoryInlineAdmin': for frm, category in zip( formset, Category.objects.all() ): frm.fields['category'].initial = category formsets.append(formset) adminForm = helpers.AdminForm(form, list(self.get_fieldsets(request)), self.prepopulated_fields, self.get_readonly_fields(request), model_admin=self) media = self.media + adminForm.media inline_admin_formsets = [] for inline, formset in zip(self.inline_instances, formsets): fieldsets = list(inline.get_fieldsets(request)) readonly = list(inline.get_readonly_fields(request)) inline_admin_formset = helpers.InlineAdminFormSet(inline, formset, fieldsets, readonly, model_admin=self) inline_admin_formsets.append(inline_admin_formset) media = media + inline_admin_formset.media context = { 'title': _('Add %s') % force_unicode(opts.verbose_name), 'adminform': adminForm, 'is_popup': "_popup" in request.REQUEST, 'show_delete': False, 'media': mark_safe(media), 'inline_admin_formsets': inline_admin_formsets, 'errors': helpers.AdminErrorList(form, formsets), 'root_path': self.admin_site.root_path, 'app_label': opts.app_label, } context.update(extra_context or {}) return self.render_change_form(request, context, form_url=form_url, add=True) #return super(ResourceUserAdmin, self).add_view(request, form_url=form_url, extra_context=extra_context) </code></pre>

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.
