一.表結構設計：

　　1.帖子：

 1 class Article(models.Model):
 2     title = models.CharField(max_length=255,unique=True)
 3     category = models.ForeignKey('Category')
 4     priority = models.IntegerField(default=1000)
 5     author = models.ForeignKey("UserProfile")
 6     content = models.TextField(max_length=100000)
 
 7     breif = models.TextField(max_length=512,default='none.....')
 8     head_img = models.ImageField(upload_to="upload/bbs_summary/")
 9     publish_date = models.DateTimeField(auto_now_add=True)
10  
11     def __unicode__(self):
12         return self.title

　　2.評論：一對多。一個帖子有多個評論，一個評論針對一個帖子：

1 class Comment(models.Model):
2     bbs = models.ForeignKey('Article')
3     parent_comment = models.ForeignKey('Comment',blank=True,null=True,related_name='p_comment')
4     user = models.ForeignKey('UserProfile')
5     comment = models.TextField(max_length=1024)
6     date = models.DateTimeField(auto_now_add=True)
 
7  
8     def __str__(self):
9         return self.comment

　　3.：　　

1 class Thumb(models.Model):
2     bbs = models.ForeignKey('Article')
3     action_choices = (('thumb_up','Thumb Up'), ('view_count',"View Count"))
4     action = models.CharField(choices=action_choices,max_length=32)
5     user = models.ForeignKey('UserProfile')
6  
7     def __str__(self):
8         return "%s : %s" %(self.bbs.title,self.action)

　　4.板塊(分類)：

1 class Category(models.Model):
2     name = models.CharField(max_length=32,unique=True)
3     enabled = models.BooleanField(default=True)
4     def __str__(self):
5         return self.name

　　5.使用者：

 1 class UserProfile(models.Model):
 2     user = models.OneToOneField(User)
 3     name = models.CharField(max_length=64)
 4     user_groups = models.ManyToManyField('UserGroup')
 5  
 6     friends = models.ManyToManyField("self",blank=True)
 7     online = models.BooleanField(default=False)
 8  
 9     def __str__(self):
10         return self.name
