장고로 이미지 업로드를 시도하는 중 int()가 유효하지 않습니다.

Question

장고 (Django) 양식을 통해 이미지를 업로드하는 중에 문제가 있습니다. 사실은 내가 https://coderwall.com/p/bz0sng/simple-django-image-upload-to-model-imagefield보다 같은 일을했다하지만 난 텍스트 필드와 이미지 필드가 포함 된 양식을 게시 할 때,이 오류 얻을 : 여기

class Projet(models.Model): 
    title = models.CharField(max_length=100) 
    subtitle = models.CharField(max_length=100) 
    content = models.CharField(max_length=4000) 
    image = models.ImageField(upload_to='projets/') 

def __unicode__(self): 
    return self.title 

class ProjetForm(forms.Form): 
    title = forms.CharField(label="", max_length=100) 
    subtitle = forms.CharField(label="", max_length=100) 
    content = forms.CharField(label="", max_length=4000, widget=forms.Textarea) 
    image = forms.ImageField(label="") 

그리고 다음은

ValueError at /prive/nouveau-projet invalid literal for int() with base 10 내 모델과 내 양식의 모델을 여기

def newProject(request): 
if request.method == 'POST': 
    form = ProjetForm(request.POST, request.FILES) 
    if form.is_valid(): 
     title = form.cleaned_data["title"] 
     subtitle = form.cleaned_data["subtitle"] 
     content = form.cleaned_data["content"] 
     image = form.cleaned_data["image"] 
     p = Projet(title, subtitle, content, image) 
     print(p.image) 
     p.save() 
    else: 
     print('fail') 
    return HttpResponse() 
else: 
    pf = ProjetForm() 
    return render(request, 'newProject.html', locals())

내 views.py의 코드는 이 특정 오류가 발생하지만, 자동으로 ModelForm를 사용하여 양식을 저장하기 위해 훨씬 더 쉽게 접근 방식을 시도하는 당신을 제안 할 수있는 이유

Answer 1

확실하지 :

class Projet(models.Model): 
    title = models.CharField(max_length=100) 
    subtitle = models.CharField(max_length=100) 
    content = models.TextField() 
    image = models.ImageField(upload_to='projets/') 

    def __unicode__(self): 
     return self.title 

class ProjetForm(forms.ModelForm): 
    class Meta: 
     model = Projet 

를 그리고, 당신이 필요로하는 모든 단지 확인 후 form.save()을 할 수있다 :

def newProject(request): 
    if request.method == 'POST': 
     form = ProjetForm(request.POST, request.FILES) 
     if form.is_valid(): 
      form.save() 
      return HttpResponseRedirect("/redirect_url/") 
    else: 
     form = ProjetForm() 
    return render_to_response('newProject.html', locals(), context_instance=RequestContext(request))
