編輯視圖不顯示django中的選擇字段數據？

Question

這是用於編輯通過profile_edit視圖的ModelForm代碼：

models.py

class Profile(models.Model): 

    user = models.OneToOneField(settings.AUTH_USER_MODEL) 
    city = models.CharField(default='kottayam', choices=CITY_CHOICES, max_length=150) 
    state = models.CharField(default='kerala', choices=STATE_CHOICES, max_length=150) 
    is_active = models.BooleanField() 

    def __unicode__(self): 
     return str(self.user) 

forms.py

class ProfileForm(forms.ModelForm): 
    class Meta: 
     model = Profile 
     exclude = ['is_active'] 

views.py

def profile_edit(request): 

    profile, created = Profile.objects.get_or_create(user=request.user) 
    form = ProfileForm(request.POST or None, request.FILES or None, instance=profile) 
    if form.is_valid(): 
     instance = form.save(commit=False) 
     instance.user = request.user 
     instance.save() 
     return redirect('profiles:profile', username=request.user.username) 

    context = { 
     "title": 'Edit Profile', 
     "form":form, 
    } 
    return render(request, 'profiles/form.html', context) 

form.html

<form method='POST' action='' enctype='multipart/form-data' role="form">{% csrf_token %} 
     {{ form|crispy }} 
     <input type='submit' class='btn btn-success' value='Add/Edit Profile' /> 
    </form> 

Charfield與選擇，情況是不可見的編輯，任何人都可以請幫助？

您需要更新ProfileForm您forms.py代碼：

class ProfileForm(forms.ModelForm): 
    class Meta: 
     model = Profile 
     fields = ('city', 'state') 
     CITY_CHOICES = your_city_choices # define your choices here. 
     STATE_CHOICES = your_state_choices 

     widgets = { 
      'city': forms.Select(choices=CITY_CHOICES), 
      'state': forms.Select(choices=STATE_CHOICES), 
     }
