利用django form 模块处理post请求

from django.db import models

TITLE_CHOICES = (
    (‘MR‘, ‘Mr.‘),
    (‘MRS‘, ‘Mrs.‘),
    (‘MS‘, ‘Ms.‘),
)

class Author(models.Model):
    name = models.CharField(max_length=100)
    title = models.CharField(max_length=3, choices=TITLE_CHOICES)
    birth_date = models.DateField(blank=True, null=True)

    def __unicode__(self):
        return self.name

class Book(models.Model):
    name = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)

from django.forms import ModelForm

class AuthorForm(ModelForm):
    class Meta:
　　　　　# 绑定模型
        model = Author
　　　　 # 忽略该字段,将其排除出处理范围之内
　　　　 exclude = (‘birth_date‘,)

class BookForm(ModelForm):
    class Meta:
　　　　 # 绑定模型
        model = Book

def testModelForm(request):
#    a=Author.objects.get(pk=1)
#    form=AuthorForm(instance=a)
    form=AuthorForm()
    if request.method==‘POST‘:
        form=AuthorForm(request.POST)
　　　　　# 如果创建form对象成功,则将数据保存
        if form.is_valid():
            form.save()
            return HttpResponseRedirect(reverse(‘welcome‘))
    return render_to_response(‘testModelForm.html‘,locals(),RequestContext(request))
