我是新的django，我正在嘗試創建博客。我已經有使用外鍵的發佈模型。用戶可以創建簡單的消息帖子，但我想走得更遠。我希望能夠爲每個帖子添加許多文件。我認爲我應該創建一個名爲Files with file area的模型。但我真的不知道如何使用文章和輸入來添加文件在帖子表單下。我聽說我需要使用formset，但我找不到任何這樣做的好例子。總之，如果你能給我一些教程（例子）或者給出一些建議如何啓動它，我將不勝感激。django創建多文件上傳表格
編輯：
我所做的一切就像例子，現在我有文件輸入形式，但這不是actualy上傳anytwhere。當我運行shell我沒有任何附件對象。繼承我的代碼。
型號：
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")

我認爲URL是罰款，所以我不要發佈。有人可以檢查它是否正確。如果不是那個有什麼問題。
