我有以下型号:Django的模型验证工作不

class CardInfo(models.Model): 
    custid = models.CharField(max_length=30, db_index=True, primary_key = True) 
    first_name = models.CharField(max_length=100) 
    last_name = models.CharField(max_length=100) 
    street = models.CharField(max_length=100) 
    building = models.CharField(max_length=100) 
    city = models.CharField(max_length=100) 
    state = models.CharField(max_length=100) 
    zipcode = models.CharField(max_length=100) 
    payment_method = models.CharField(max_length=100, null=True, blank=True) 
    amount = models.CharField(default = '0',max_length=10, null=True, blank=True) 
    valid_to_month = models.CharField(max_length=100, null=True, blank=True) 
    valid_to_year = models.CharField(max_length=100, null=True, blank=True) 
def __unicode__(self): 
    return "Cust ID %s" %(self.custid) 

在shell中,当我给full_clean我得到验证错误,但在保存它那得到保存,而不是抛出错误。为什么这样呢?我使用django1.3和Python 2.6:

c=CardInfo(custid="Asasasas") 
c.full_clean() 
Traceback (most recent call last): 
File "<console>", line 1, in <module> 
File "/usr/local/python2.6/lib/python2.6/site-packages/django/db/models/base.py", line 828, in full_clean 
raise ValidationError(errors) 
ValidationError: {'building': [u'This field cannot be blank.'], 'city': [u'This field cannot be blank.'], 'first_name': [u'This field cannot be blank.'], 'last_name': [u'This field cannot be blank.'], 'zipcode': [u'This field cannot be blank.'], 'state': [u'This field cannot be blank.'], 'street': [u'This field cannot be blank.']} 
c.save()

它应该给完整性错误。您的模型/数据库同步正确吗?您的应用程序的sqlall将有所帮助。 – Rohan 2012-08-03 04:59:51

的文档explicit about this

注意验证器,当你保存模型将不会自动运行,但如果您使用的是的ModelForm,它会在您的表单中包含的任何字段上运行您的验证器。

如果您没有使用表单,则在保存之前调用clean方法是您的责任。

调用模型验证可以强制这样的:

model_instance.full_clean()
