Question

我想要一個視圖，可以在我創建的模型「聯繫人」中添加新聯繫人。 下面是一些代碼行被關注

views.py：

---

def contact(request): 
form = ContactForm(request.POST or None) 
if form.is_valid(): 
    sujet = form.cleaned_data['sujet'] 
    message = form.cleaned_data['message'] 
    envoyeur = form.cleaned_data['envoyeur'] 
    renvoi = form.cleaned_data['renvoi'] 
    envoi = True 
return render(request, 'blog/contact.html', locals()) 

def nouveau_contact(request): 
sauvegarde = False 
form = NouveauContactForm(request.POST or None, request.FILES) 
if form.is_valid(): 
    contact = Contact() 
    contact.nom = form.cleaned_data["nom"] 
    contact.adresse = form.cleaned_data["adresse"] 
    contact.photo = form.cleaned_data["photo"] 
    contact.save() 
    sauvegarde = True 
return render(request, 'blog/newcontact.html', { 
    'form': form, 
    'sauvegarde': sauvegarde 
})

forms.py：

---

class ContactForm(forms.Form): 
    sujet = forms.CharField(max_length=100) 
    message = forms.CharField(widget=forms.Textarea) 
    envoyeur = forms.EmailField(label="Votre adresse mail") 


class NouveauContactForm(forms.Form): 
    nom = forms.CharField() 
    adresse = forms.CharField(widget=forms.Textarea) 
    photo = forms.ImageField() 

class Contact(models.Model): 
    nom = models.CharField(max_length=255) 
    adresse = models.TextField() 
    photo = models.ImageField(upload_to="photos/") 

    def __str__(self): 
     return self.nom 

錯誤消息告訴我「」NewContactForm「」未定義 this is the ERROR_MESSAGE

添加在頂部視圖，

from .forms import NouveauContactForm 

你忘了進口形式。
