Ok I'm totally lost here. I've created an edit function which works
splendidly except for the inline-part, it displays alright but it isn't
saved at all.
My models look like this:
==================
class Recipe(models.Model):
author = models.ForeignKey(User)
name = models.CharField(max_length=255, verbose_name='Namn på rätten')
category = models.ForeignKey('Category', verbose_name='Kategori')
create_date = models.DateTimeField(auto_now_add=True)
servings = models.CharField(max_length=10, verbose_name='Portioner')
cooking_time = models.CharField(max_length=10,
verbose_name='Tillagningstid')
ingredients = models.TextField(verbose_name='Ingridienser')
instructions = models.TextField(verbose_name='Instruktioner')
oven_heat = models.CharField(max_length=10, null=True, blank=True,
verbose_name='Ugnsvärme')
serving_tips = models.TextField(null=True, blank=True,
verbose_name='Serveringsförslag')
tags = TagField(verbose_name='Taggar')
slug = models.SlugField()
published = models.NullBooleanField(default=1)
class Image(models.Model):
recipe = models.ForeignKey(Recipe)
file = models.ImageField(upload_to=get_file_path)
My view looks like this:
=================
from django.shortcuts import render_to_response, get_object_or_404
from django.template import RequestContext
from django.http import HttpResponseRedirect
from nitsche.recipes.models import Category, Recipe, Image
from nitsche.recipes.forms import RecipeForm
from django.contrib.auth.decorators import login_required
from django.forms.models import inlineformset_factory
@login_required
def edit(request, slug):
ImageFormSet = inlineformset_factory(Recipe, Image)
recipe = Recipe.objects.filter(published=True).get(slug=slug)
form = RecipeForm(instance=recipe)
formset = ImageFormSet(instance=recipe)
if request.method == 'POST':
form = RecipeForm(request.POST, instance=recipe)
formset = ImageFormSet(request.POST, request.FILES, instance=recipe)
if form.is_valid(): # All validation rules pass
form.save()
if formset.is_valid():
formset.save()
return HttpResponseRedirect('/recept')
return render_to_response('recipes/add.html',
{'form': form, 'formset': formset,
'slug':slug,},
context_instance=RequestContext(request))
And finaly my template looks like this:
============================
<form action="/recept/edit/{{ slug }}/" method="POST">
{{ form.as_p }}
<table>
{{ formset }}
</table>
<input type="submit" value="Submit" />
</form>
Every change I make in the main form (for the recipe-model) is saved but
nothing from the inline_formset (the image-model). I get no error or
anything, it behaves as if it is saving all the data but in the reality
nothing in the inline_formset is saved. I've read the documentation and as
far as I understand it should work this way. When I add or edit an item in
the backend it works as it should. Can somebody point out what I'm doing
wrong? At this point I am starting to feel a little desperate and any nudge
in the right direction would be greatly appreciated.
