Body
Two examples only slightly different: First: <pre><code>class ScanInlineAdmin(admin.TabularAdmin): model = Scan formset = ScanInlineFormset def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "visit": patient = self.get_object(kwargs['request'], Patient) kwargs["queryset"] = Visit.objects.filter(patient=patient) return super(ScanInlineAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs) def get_object(self, request, model): object_id = request.META['PATH_INFO'].strip('/').split('/')[-1] try: object_id = int(object_id) except ValueError: return None return model.objects.get(pk=object_id) </code></pre> Second: <pre><code>class ScanInline(admin.TabularInline): model = Scan formset = ScanInlineFormset def formfield_for_dbfield(self, field, **kwargs): if field.name == 'visit': # Note - get_object hasn't been defined yet patient = self.get_object(kwargs['request'], Patient) vists = Visit.objects.filter(patient=patient) return forms.ModelChoiceField(queryset=visits) return super(ScanInline, self).formfield_for_dbfield(field, **kwargs) def get_object(self, request, model): object_id = request.META['PATH_INFO'].strip('/').split('/')[-1] try: object_id = int(object_id) except ValueError: return None return model.objects.get(pk=object_id) </code></pre> You may find this <a href="http://www.stereoplex.com/blog/filtering-dropdown-lists-in-the-django-admin" rel="nofollow">article</a> helpful. I assume your in the patient page admin edit/view where you want to enter the new scan. Is that correct?

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.
