If you need to edit the race and the candidates on the same page, and
the candidates are FK'ed to the race, I'd do it like this:
(Warning, just coding off the top of my head, might have bad syntax/
imports)
forms.py
-----------------
from django import forms
from django.forms.models import modelformset_factory
from models import Candidate, Race
class RaceForm(forms.ModelForm):
class Meta:
model = Race
CandidateFormSet = modelformset_factory(Candidate, extra=0)
views.py
------------------
from django.shortcuts import get_object_or_404, redirect
from django.views.generic.simple import direct_to_template
from forms import RaceForm, CandidateFormSet
from models import Candidate, Race
def edit_race(request, race_slug):
race = get_object_or_404(slug=race_slug)
race_form = RaceForm(request.POST or None, instance=race)
candidate_formset = (request.POST or None,
queryset=Candidate.objects.filter(race=race))
if race_form.is_valid() and candidate_formset.is_valid():
race_form.save()
candidate_formset.save()
return redirect('.') #Or whatever page you want them to go to
after saving
return direct_to_template(request, 'edit_race.html', {
'race_form': race_form,
'candidate_formset': candidate_formset,
})
edit_race.html
---------------------
{% block content %}
<form action="." method="post">
{{ race_form }}
{{ candidate_formset }}
<button type="submit">Save</button>
</form>
{% endblock %}
Hope I understood the question and that this helps,
Alex
