Django默认字段验证在Ajax调用中跳过

Question

我浪费了大量的时间，最终在这个伟大的论坛寻求帮助。我有一个Django的起动器，并在一个模型表单上处理来自用户的地址细节，并通过重写字段的干净方法进行验证。当我尝试使用ajax调用Ajax调用时由于某种原因而跳过表单验证时，开始出现问题。请指导我，我无法弄清楚为什么我的视图中的is_valid（）值会变为True，尽管视图函数调用了包含所有验证方法的AdrressForm对象。

// IN my views.py// 
@transaction.atomic 
def update_profile_address(request): 
    user = request.user 
    if request.method == 'POST': 
     address_form = AddressForm(request.POST, instance=user.profile) 
     if address_form.is_valid(): 
      address_form.save() 
      response_data = {"success_message": " Details Saved Successfully."} 
      return HttpResponse(
      json.dumps(response_data), 
      content_type="application/json" 
      ) 
    else: 
     address_form = AddressForm(instance=user.profile) 
    return render(request, 'update_profile_address.html', { 
     'address_form': address_form, 
     }) 

//in my forms.py // 
class AddressForm(forms.ModelForm): 
    class Meta: 
     model = Profile 
     fields = ('address_city', 'address_state','address_country','address_pin') 
     labels = { 
        'address_city': 'City', 
        'address_state':'State', 
        'address_country': 'Country', 
        'address_pin':'Pincode', 
     } 
     widgets = { 
      'address_city': forms.TextInput(
       attrs={ 'required': True, 'placeholder': 'your city'} 
      ), 
      'address_state': forms.TextInput(
       attrs={'required': True, 'placeholder': 'Madhya Pradesh'} 
      ), 
      'address_country': forms.TextInput(
       attrs={ 'required': True, 'placeholder': 'India'} 
      ), 
      'address_pin': forms.TextInput(
       attrs={ 'required': True, 'placeholder': 'your pin code'} 
      ), 
     } 

     def clean_address_city(self): 
      address_city = self.cleaned_data['address_city'] 
      print(address_city) 
      if not address_city.isalpha(): 
       raise forms.ValidationError('Location can be alphabetic only.') 
      return address_city 

     def clean_address_state(self): 
      address_state = self.cleaned_data['address_state'] 
      if not address_state.isalpha(): 
       raise forms.ValidationError('State can be alphabetic only.') 
      return address_state 

     def clean_address_country(self): 
      address_country = self.cleaned_data['address_country'] 
      if not address_country.isalpha(): 
       raise forms.ValidationError('Country name can be alphabetic only.') 
      return address_country 

     def clean_address_pin(self): 
      address_pin = self.cleaned_data['address_pin'] 
      if not address_pin.isnumeric(): 
       raise forms.ValidationError('Pin can be numeric only.') 
      return address_pin 

// ajax call // 
    $("#tab2_2").click(function(event){ 
     event.preventDefault(); 
     $('li.active').removeClass('active'); 
     $(this).closest('li').addClass('active'); 
     var url = $(this).attr('href'); 
     $.ajax({ 
      url: url, 
      success: function(data){ 
       document.getElementById("inner-content").innerHTML = data; 
       $('#address-form').submit(function(event){ 
        event.preventDefault(); 
        console.log('form submission prevented'); 
        address_form_submit(); 

       }) 

      } 

     }); 
    }); 

    function address_form_submit(){ 
     console.log($('#address-form').serialize()); 

     $.ajax({ 
        url:"{% url 'update_profile_address' %}", 
        type:"POST", 
        /*data : { address_city : $('#address_city').val(), 
          address_state: $('#address_state').val(), 
          address_country:$('#address_country').val(), 
          address_pin:$('#address_pin').val(), 
          csrfmiddlewaretoken : '{{ csrf_token }}' 
        }, */ 
        dataType: "json", 
        data: $('#address-form').serialize(), 
        success: function(json){ 
        console.log(json); 
        var msg_box = document.getElementById('message-box'); 
        if (json.success_message) { 
         msg_box.innerHTML = json.success_message; 
         $('#message-box').addClass("alert-success"); 


        }; 


        } 
       }) 

    };

缩进问题。你的干净方法在Meta类中。
