Django1.4 form.is_valid（）总是返回true

Question

class ContactForm(forms.Form): 
    subject = forms.CharField() 
    email = forms.EmailField(required = False) 
    message = forms.CharField() 

蟒蛇壳：

>>> f = ContactForm({'subject': 'Hello'}) 
>>> f.is_valid() 
>>> True 

这不是我所期待的。

Answer 1

这不是答案，但我没有看到这样的行为。在我的情况下，表格无效。 这是从django的外壳，

>>> class ContactForm(forms.Form): 
...  subject = forms.CharField() 
...  email = forms.EmailField(required = False) 
...  message = forms.CharField() 
... 
>>> 
>>> 
>>> cf = ContactForm({'subject': "hello"}) 
>>> cf.is_valid() 
False 
>>> cf.errors 
{'message': [u'This field is required.']}
