Body
The tricky part is basically the rendering of the <code>Temp.food</code> as something other than a select widget(which is the default for ForeignKey relationships). For this you'd have to subclass the <code>Select</code> widget and override the <code>render</code> method to output just a label with the selected value <pre><code>from django.forms.widgets import Select class MyLabelSelect(Select): def render(self, name, value, attrs=None, choices=()): # read the django.forms.widgets.Select.render() source to # understand what you have to do here. Not that hard. pass </code></pre> A formset is indeed what you need here, with a caveat: you'll need to pass it a slightly custom form that uses your new widget for the FK relationship. <pre><code>from django import forms from .widgets import MyLabelSelect from .models import Temp class TempForm(forms.ModelForm): class Meta: model = Temp exclude = ('date', 'time') widgets = { 'food': MyLabelSelect } </code></pre> OK now we need to construct the actual formset <pre><code>from django.forms.models import modelformset_factory from .forms import TempForm from .models import Temp def my_view(request): TempFormset = modelformset_factory( Temp, form = TempForm, max_num = Temp.objects.count() ) if request.method == 'POST' and request.POST: # I'll just demonstrate the GET request pass else: # Grab the Temp objects we want temps = Temp.objects.filter(food__tracktemp=True) temp_formset = TempFormset( queryset=temps ) return render_to_response(....) </code></pre> Haven't actually tested the above code, but something along those lines is what you're after. If I have any glaring errors tell me and I'll correct them.

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.
