« image » est un argument de mot-clé non valide pour cette fonction

Question

Voici l'erreur:

'image' is an invalid keyword argument for this function 

Toute aide à comprendre ce qui se passe et comment y remédier serait très apprécié.

Fondamentalement, j'ai un modèle 'Partenaire' avec une relation un à plusieurs à un modèle 'Produit'. J'utilise inlineFormSet pour le modèle 'Product' qui a des champs comme partenaire, image, desc, prix, etc.

Le formulaire s'affiche correctement dans admin et quand le formulaire est rendu, mais lors de la soumission il renvoie l'erreur.

ici est mon views.py

def partner_create(request): 
#Trying to add multiple product functionality 
    if not request.user.is_staff or not request.user.is_superuser: 
     raise Http404 

    ProductFormSet = inlineformset_factory(Partner, Product, form=ProductForm, extra=3) 

    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: 
       image = form['image'] 
       product = Product(partner=instance, 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}) 

ici est mon models.py

    product_image = models.ImageField(upload_to=upload_location,

    price = models.DecimalField(max_digits=6, decimal_places=2) 
    height_field = models.IntegerField(default=0) 
    width_field = models.IntegerField(default=0) 

    def __unicode__(self):    # __unicode__ on Python 2 
     return self.name 

ici est mon forms.py

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", 
      "image", 
      "description", 
      "price" 
     ] 

Je comprends que le problème est avec cette ligne dans le views.py

product = Product(partner=instance, image=image) 

Mais je ne comprends pas pourquoi ce que j'ai fait ne fonctionne pas "image = image" (je l'ai vu fait comme ça avant) ou où aller à partir d'ici. Merci à l'avance

Vous êtes le nom du mal orthographié champ tel qu'il est pas image mais product_image. Modifiez la ligne suivante:

product = Product(partner=instance, image=image) 

à

product = Product(partner=instance, product_image=image)
