关于 ThinkPHP 中建立模型的问题,可以不可以不要每个表都建立模型
关于 ThinkPHP 中建立模型的问题,可以不可以不要每个表都建立模型
按照我们 以前的办法 需要给每个表都要建立一个模型 例如 设计到用户有4张表 每个表我都要建立模型 分别进行增删改查
可以我发现有虚拟模型可以用 我建立一个虚拟模型 这个我用户这个我只需要建立一个 User 类 直接 D(User) 可是按照道理 虚拟模型就不应该对数据库操作. 例如这样我自动完成 自动验证就无法执行.请问有什么办法可以 将原先要建立4个模型的操作,合并成只要一个模型 除了虚拟模型还有什么办法?

搜索看看:关联模型 是不是你想要的
模型你可以随便建的,例如你建一个AbcModel.class.php,里面具体的方法具体怎么实现你自己写就好啊。就是你设想的方式,调用的时候直接D()就可以了,自动完成什么的就当然只能算了,其实感觉这个实际工作中用的好少,毕竟我觉得自动校验效率低。。。
可以的,模型和表之间没有绝对的关系!
用大M方法,只是用来做数据的CURD,实例化其实并没有的类。官方文档:http://document.thinkphp.cn/manual_3_2.html#model_instance
