無效字面INT（）基數爲10： '微' 在Django的網頁

Question

林與SQL腳本插入到該數據：

INSERT INTO "siteDB_accounttype" VALUES 
(1,'Micro'), 
(2,'Standart'), 
(3,'МТ-ECN'); 

而且必須在Django的驗證碼（使用Python 2.7版）：
1）的views.py

def registration(request): 
    reg_form = RegisterForm() 
    title = 'Регистрация клиента' 
    return render_to_response('registration.html', locals()) 

2）forms.py

class RegisterForm(forms.Form): 
    ids = AccountType.objects.values_list('Name', flat=True) 
    acc_types_lst = AccountType.objects.filter(pk__in=set(ids)) 
    Name = forms.CharField(max_length=255, required=True, label='Имя') 
    Surname = forms.CharField(max_length=255, required=True, label='Фамилия') 
    DateOfBirth = forms.DateField(required=True, label='Дата рождения') 
    Address = forms.CharField(max_length=255, required=True, label='Адрес', 
          widget=forms.Textarea(attrs={'cols': 55, 'rows': 5})) 
    Postcode = forms.IntegerField(min_value=100000, max_value=999999, required=True, label='Почтовый индекс') 
    Phone = forms.CharField(max_length=50, required=True, label='Телефон') 
    PassportID = forms.CharField(max_length=50, required=True, label='Номер паспорта') 
    AccountType = forms.ChoiceField(choices=[AccType for AccType in acc_types_lst], 
           required=True, label='Тип счета') 
    DepositeSize = forms.IntegerField(min_value=500, required=True, label='Начальный вклад') 

3）的models.py

from django.utils.encoding import smart_unicode 
class AccountType(models.Model): 
    ID = models.IntegerField(primary_key=True, blank=False) 
    Name = models.CharField(max_length=50, unique=True, blank=False) 

    def __unicode__(self): 
     return smart_unicode(self.Name) 

，但得到我的瀏覽器：

ValueError at /registration/ 
invalid literal for int() with base 10: 'Micro' 

完全回溯：

我怎樣才能解決這個問題？

Answer 1

似乎有在你的代碼一個錯字，改變

class RegisterForm(forms.Form): 
    ids = AccountType.objects.values_list('Name', flat=True) 

到

class RegisterForm(forms.Form): 
    ids = AccountType.objects.values_list('id', flat=True) 

由於通過Name S（串），而不是ID s到錯字以後過濾帳戶類型列表（整數），

acc_types_lst = AccountType.objects.filter(pk__in=set(ids)) 

因此錯誤。
