tag与user表之间是多对多关系就行了。在全局查看时，不处理user表，但在用户视角时，处理user信息。

因为有第三张表，可以通过命令行sqlall 查看建表的sql。因此从原来的两张表是看不出有什么关系的。

这个是由django自动做的，具体的比较复杂，我也不是特别的清楚，主要的密秘都在它的model类中了。在model中专门有一个manytomany的字段，具体叫什么我忘了，它会根据这个字段去找对应的其它的表。对于没有存放manytomany字段的表，在你使用时一般是：

tableb_set，这样根据这个特殊的_set后缀django会知道你想访问一个关系表，它会去查找是否有多对一，还是多对多的关系，然后如果找到了，再进行处理。
