Question

我是django的新手，我正在尝试创建博客。我已经有用户使用外键的帖子模型。用户可以创建简单的消息帖，但我想进一步。我希望能够为每个帖子添加许多文件。我认为我应该创建一个名为Files with file area的模型。但我真的不知道如何制作一个带有帖子和输入的表格，以便在帖子表格下添加文件。我听说我需要使用formset，但是我找不到做这样的事情的好例子。总而言之，如果你能给我发一些教程（例子）或给出一些如何启动它的建议，我将不胜感激。

编辑：

我做了所有的事情，就像在示例中一样，现在我的表格有文件输入，但这不是实际上传的任何地方。当我运行shell时，我没有任何附件对象。继承我的代码。

型号：

 from django.db import models
from django.contrib.auth.models import User
from multiupload.fields import MultiFileField
import datetime
class PostManager(models.Manager):
    def published(self, ):
        return self.get_queryset().filter(active=True, pub_date__lt=datetime.datetime.now())

class Post(models.Model):
    author=models.ForeignKey(User, verbose_name=u"Autor postu", blank=True, null=True)
    active=models.BooleanField(verbose_name=u"Aktywnosc postu", default="False")
    title=models.CharField(max_length=40, verbose_name=u"tytul")
    lead=models.TextField(verbose_name=u"wprowadzenie")
    body=models.TextField(verbose_name=u"Zawartosc postu")
    pub_date=models.DateTimeField(verbose_name=u"Data publikacji", blank="True", null="True")

    objects= PostManager()

    class Meta:
        verbose_name=u"post"
        verbose_name_plural=u"posty"

class Attachment(models.Model):
    post = models.ForeignKey(Post, verbose_name=u"post")
    file = models.FileField(upload_to='attachments', verbose_name=u"Plik")
    file_name=models.TextField(verbose_name=u"Nazwa pliku")
