利用django form 模块处理post请求

在django框架中,利用 form 模块处理post请求提交的数据,可以大大提高开发效率,减小代码冗余度,提高性能

models.py 中:

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)

自定义的form.py文件


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

views.py中

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))
