BBS论坛项目

一.表结构设计：

　　1.帖子：

 class Article(models.Model):
     title = models.CharField(max_length=255,unique=True)
     category = models.ForeignKey('Category')
     priority = models.IntegerField(default=1000)
     author = models.ForeignKey("UserProfile")
     content = models.TextField(max_length=100000)
     breif = models.TextField(max_length=512,default='none.....')
     head_img = models.ImageField(upload_to="upload/bbs_summary/")
     publish_date = models.DateTimeField(auto_now_add=True)

     def __unicode__(self):
         return self.title

　　2.评论：一对多。一个帖子有多个评论，一个评论针对一个帖子：

 class Comment(models.Model):
     bbs = models.ForeignKey('Article')
     parent_comment = models.ForeignKey('Comment',blank=True,null=True,related_name='p_comment')
     user = models.ForeignKey('UserProfile')
     comment = models.TextField(max_length=1024)
     date = models.DateTimeField(auto_now_add=True)

     def __str__(self):
         return self.comment

　　3.：　　

 class Thumb(models.Model):
     bbs = models.ForeignKey('Article')
     action_choices = (('thumb_up','Thumb Up'), ('view_count',"View Count"))
     action = models.CharField(choices=action_choices,max_length=32)
     user = models.ForeignKey('UserProfile')

     def __str__(self):
         return "%s : %s" %(self.bbs.title,self.action)

　　4.板块(分类)：

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

　　5.用户：

 class UserProfile(models.Model):
     user = models.OneToOneField(User)
     name = models.CharField(max_length=64)
     user_groups = models.ManyToManyField('UserGroup')

     friends = models.ManyToManyField("self",blank=True)
     online = models.BooleanField(default=False)

     def __str__(self):
         return self.name
