imlearningdjango1.8（python2.7.8），我试图验证email、firstname和lastname场。那个问题是我插入表单的内容都会保存到数据库中（只有默认的电子邮件验证有效）。下面是我的表单，视图，模型和管理文件的外观就像。任何人建议？谢谢你

在模型.py在

from django.db import models

# Create your models here.

class SignUp(models.Model):
email = models.EmailField()
first_name = models.CharField(max_length=25,blank=True,null=True)
last_name = models.CharField(max_length=25,blank=True,null=True)
timestamp = models.DateTimeField(auto_now_add=True,auto_now=False)
updated = models.DateTimeField(auto_now_add=False,auto_now=True)

def __unicode__(self):
    return self.email

在管理员py在

^{pr2}$

在视图.py在

from django.shortcuts import render
from forms import SignUpForm

# Create your views here.
def home(request):
    title = "Welcome"
    form = SignUpForm(request.POST or None)
    context = { "title": title,"form":form, }
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
    return render(request, "home.html", context)

在表单.py在

from django import forms
from .models import SignUp
import re

class SignUpForm(forms.ModelForm):
    class Meta:
        model = SignUp
        fields = ['first_name','last_name','email']
    def clean_email(self):
        email = self.cleaned_data.get('email')
        email_base, provider = email.split('@')
        domain,extension = provider.split('.')
        if provider.count('.')  > 2: #email provider should not have more than 2 "dots=> ."
            raise forms.ValidationError("Please use valid email address")
        return email
    def clean_first_name(self):
        first_name = self.cleaned_data.get('first_name')
        if bool(re.search('[\d\s]',first_name)): #firstname should not have whitespace or digits
            raise forms.ValidationError("Please dont use numbers or space in Name Field")
        return first_name
    def clean_last_name(self):
        last_name = self.cleaned_data.get('last_name')
        if bool(re.search('[\d]',last_name)): #lastname should not have digits
            raise forms.ValidationError("Please dont use numbers or space in Name Field")
        return last_name

在网址.py在

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$','newsletter.views.home', name='home'),
        ]

在主页.html在

<html>
<title>Home Page</title>
<body>
{{ title }} {{ request.user }} <br>
    <form method="post" action="">
     {% csrf_token %}

    {{ form.as_p }}
    <input type="submit" value="submit">
</form>
</body>
</html>

你的表单.py看起来不错。我想你没有在模板HTML中显示错误。
{%如果表格错误%}
{%中的错误表格错误%}
{{errors}}
{%endfor%}
{%endif%}

我犯了一些愚蠢的错误（缩进）。问题已更正，编码正确
