Re: Models, forms and inlineformset

[andreas schmid]

is this an add or an edit form? or both?

i have a similar inlineformset and i need to loop over the inline
objects to set the foreignkey to the parent object like:

if form.is_valid() and formset.is_valid(): # All validation rules pass
new_idea = form.save(commit=False)
new_idea.author = request.user
new_idea = form.save()
formset_models = formset.save(commit=False)
for f in formset_models:
f.idea = new_idea
f.save()
return HttpResponseRedirect(new_idea.get_absolute_url())


im actually experiencing problems with the edit form where i can get the
values displayed in the form if i want to edit but i get a

Exception Type: MultiValueDictKeyError
Exception Value:

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.as_p }}

{{ formset }}




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.

Models, forms and inlineformset

[Stefan Nitsche]

Hi,

to begin with I would like to declare that I'm still on the beginner end of
the scale when it comes to Python and Django.

I have an app which has two models:

class Item(models.Model):
title = models.CharField()
description_markdown = models.TextField()

class ItemImage(models.Model):
item = models.ForeignKey(Item)
image = models.ImageField(upload_to='tmp')

What I want to do now is to create a page where users can submit an item and
upload an image (or images) at the same time. I can create a form using
ModelForm for the Item-model and I can create a form for the ItemImage-model
using inlineformset_factory, if I do this the submit page looks like it
should. However it doesn't behave the way I want it to when saving, but to
be honest I have no real idea of what I'm doing when it comes to the related
model/form.

If I understand it correctly when using inlineformset_factory I must give it
an instance so that it can map the foreignkey, correct? So how do one go
about and create a form where people can add "item" and "itemimages" at the
same time? I'm feeling totaly lost any pointers would be greatly
appreciated.
