KeyError at /partners/create/ 'name' - django

Question

I have a model Partner that is related to Product by a one to many relationships. I am using inlineformsets for the Product and I am gettig the following error which I don't understand:"KeyError at /partners/create/ 'name'"
my views are as follows:
def partner_create(request):
if not request.user.is_staff or not request.user.is_superuser:
raise Http404
ProductFormSet = inlineformset_factory(Partner, Product, form=ProductForm, extra=3, min_num=1)
if request.method == 'POST':
partnerForm = PartnerForm(request.POST or None, request.FILES or None)
formset = ProductFormSet(request.POST, request.FILES, queryset=Product.objects.none())
if partnerForm.is_valid() and formset.is_valid():
instance = partnerForm.save(commit=False)
instance.save()
for form in formset.cleaned_data:
name = form["name"]
description = form["description"]
price = form["price"]
image = form["image"]
product = Product(partner=instance, name=name, description=description, price=price, product_image=image)
product.save()
messages.success(request, "Partner Successfully Created")
else:
print partnerForm.errors, formset.errors
else:
partnerForm = PartnerForm()
formset = ProductFormSet(queryset=Product.objects.none())
return render(request, "partner_form.html", {"partnerForm": partnerForm, "formset": formset})
my forms.py are as follows:
class PartnerForm(forms.ModelForm):
mission = forms.CharField(widget=PagedownWidget(show_preview=False))
vision = forms.CharField(widget=PagedownWidget(show_preview=False))
# publish = forms.DateField(widget=forms.SelectDateWidget)
class Meta:
model = Partner
fields = [
"name",
"logo",
"banner_image",
"mission",
"vision",
"website_link",
"fb_link",
"twitter_link",
"ig_link",
]
class ProductForm(forms.ModelForm):
image = forms.ImageField(label='Image')
class Meta:
model = Product
fields = [
"partner",
"name",
"description",
"price",
"image",
]
My models.py are as follows:
def upload_location(instance, filename):
#filebase, extension = filename.split(".")
# return "%s/%s" %(instance.name, instance.id)
PartnerModel = instance.__class__
exists = PartnerModel.objects.exists()
if exists:
new_id = PartnerModel.objects.order_by("id").last().id + 1
else:
new_id = 1
file_name, file_extension = filename.split('.')
return "%s/%s/%s-%s.%s" %('partner',instance.name, file_name, new_id, file_extension)
class Partner(models.Model):
name = models.CharField(max_length=120)
logo = models.ImageField(upload_to=upload_location,
null=True,
blank=True,
width_field="width_field",
height_field="height_field")
banner_image = models.ImageField(upload_to=upload_location,
null=True,
blank=True,
width_field="width_field",
height_field="height_field")
mission = models.TextField()
vision = models.TextField()
height_field = models.IntegerField(default=0)
width_field = models.IntegerField(default=0)
# text = models.TextField()
website_link = models.CharField(max_length=120)
fb_link = models.CharField(max_length=120)
twitter_link = models.CharField(max_length=120)
ig_link = models.CharField(max_length=120)
slug = models.SlugField(unique=True)
updated = models.DateTimeField(auto_now=True, auto_now_add=False)
timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)
def __unicode__(self):
return self.name
def get_absolute_url(self):
return reverse("partners:detail", kwargs={"slug": self.slug})
# return "/partner/%s/" %(self.id)
def get_markdown(self):
mission = self.mission
markdown_text = markdown(mission)
return mark_safe(markdown_text)
#Creating a many to one relationship so that one can upload many Products
class Product(models.Model):
partner = models.ForeignKey(Partner, default=None)
name = models.CharField(max_length=120)
product_image = models.ImageField(upload_to=upload_location,
# product_image = models.ImageField(upload_to= (upload_location + '/' + name), Something like this need to append actual product name so these dont just get dumped in the media for partners
null=True,
blank=True,
width_field="width_field",
height_field="height_field",
verbose_name='Image',)
description = models.TextField()
price = models.DecimalField(max_digits=6, decimal_places=2, null=True)
height_field = models.IntegerField(default=0)
width_field = models.IntegerField(default=0)
def __unicode__(self): # __unicode__ on Python 2
return self.name
I would really like to understand what is going on as well as how to fix it or a hint in the right direction. Thank you in advance for your help!

Answer 1

To find out why you're getting the error, you should add some printing or logging to your code. What is the value of formset.cleaned_data? Is it what you think it should be?
There's a simpler approach that looping through the formset's cleaned_data. The docs show how to save a formset. You can save with commit=False, then set the partner field before saving to the database.
products = formset.save(commit=False)
for product in products:
product.partner=instance
product.save()
Note that if you do this, you should probably switch to a modelformset_factory instead of inlineformset_factory, and remove partner from the list of the fields of the ProductForm.

Answer 2

The formset form save method seems incorrect, use something like
for form in formset.cleaned_data:
if form.is_valid():
name = form.cleaned_data.get("name")
description = form.cleaned_data.get("description")
price = form.cleaned_data.get("price")
image = form.cleaned_data.get("image")
Please lemme know if this works :)
