python3.4 + Django1.7.7 Some problems with forms

The above is not called cleaned_data the results of the submission, the visible template directly to the form of the entire label is received.

The following is the result of calling Cleaned_data

The Django form, which is then submitted, is this:

#coding: Gb2312from Django Import Formsclass contactform (forms. Form):    subject = forms. Charfield (max_length=10,label= ' subject ') #设置最大长度为10    email = forms. Emailfield (required=false,label= ' Email ') #非必要字段    message = forms. Charfield (widget=forms. textarea,label= ' message ') #指定form中组件的类型    #自定义校验规则, which is automatically called by the system at checksum, in order after "field constraint"    def clean_message (self):        message = self.cleaned_data[' message '] #能到此处说明数据符合 field constraint requires        num_words = Len (Message.split ())        if num_ Words < 1: #单词个数            raise forms. ValidationError ("Your word is too short!")        Return message

For example, the following sentence:

email = forms. Emailfield (required=false,label= ' Email ') #非必要字段

Can actually be used as a non-essential field, Required=false

Since the call to form.cleaned_data# only has the corresponding cleaned_data when each field meets the requirements, it must have been before:

If Form.is_valid (): #说明各个字段的输入值都符合要求

Therefore, the above fields Required=false, in testing things or writing their own things, such as the safety of the occasion is more necessary
