6(just form no database)

添加一个不需要写入数据库的表单contact

1. 在forms.py中添加contact类

class ContactForm(forms.Form):
    name = forms.CharField(max_length=120)
    email = forms.EmailField()
    phonenumber = forms.CharField(max_length=20)
    def clean_email(self):
        email = self.cleaned_data.get('email')
        email_base, email_provider = email.split("@")
        email_domain, email_extension = email_provider.split('.')
        print(email_base, email_provider, email_domain, email_extension)
        if not email_domain == '163':
            raise forms.ValidationError("you should input 163 email")
        return email #实际上被写入的email的值

2. 在views.py里添加如下代码:

def contact(request):
    form = ContactForm(request.POST or None)
    title = "hi contact"
    if form.is_valid():
        for key,value in form.cleaned_data.items():#python2.7使用iteritems()
            print(key,value)
    context = {
        'form':form,
        'title':title,
    }
    return render(request, 'contact.html', context)

3. 在templates文件夹下面添加contract.html文件

<h1>{{ title }}</h1>
<form method="POST" action=""> {% csrf_token %}
    {{ form.as_p }}<!-- as_p的作用是让他按行显示，而不是显示在一行 -->
    <input type="submit" value="submit">
</form>
