ModelForm。爲什麼我的表單沒有填充模型的數據？

Question

爲什麼我的表單沒有填充模型的數據？

這是我model.py

class People(models.Model): 
    user = models.OneToOneField(User) 
    name = models.CharField(max_length=100) 
    address = models.CharField(max_length=255) 

這是我forms.py

from django.forms import ModelForm 

class EditForm(ModelForm): 
    class Meta: 
     model = People 
     exclude=('user',) 

views.py

def edit_data(request): 
    user = request.user 
    people = People.objects.get(user=user) 
    form = EditForm(request.POST, instance = people) 
    if request.method == 'POST': 
     if form.is_valid(): 
      form.save() 
     else: 
      print 'Error' 
    else: 
     form = EditForm() 

    return render_to_response('profile.html',{'form':form}, context_instance=RequestContext(request)) 

profile.html

<form action="/profile/" method="post">{% csrf_token %} 
{{ form.as_p }} 
</form>

問題是，您正在else子句中重新定義form（到EditForm的新實例，該實例沒有instance變量集）。刪除else（和它下面的行），你應該很好去。
