Basic use of the Kohana framework ORM Class, Kohana framework Orm

1. First, you need to create a model class, in the case of the user,application/classes/model/user.php路径下创建user.php，并且一个表对应一个模型，且表名必须在类名后加“S”，即表名应该为users，在这个文件中，需要继承ORM类：

 
  extends orm{    ... }?>

Create an ORM instance on the controller (the access method must be prefixed with "Action_", The inherited class "Controller_admin" is for the convenience of the control of the permissions):

 
  PHPclassextends  controller_admin{    publicfunction  action_ Test ()    {        $user = orm::factory (' user ');
        Insert
        $user->name = ' Tina ';
        $user->age = ' 22 ';
        $user->save ();
        Query the record, get the result is an object
        $result = orm::factory (' user ')->where (' id ', ' = ', 1)->find ();
        Update, where the second parameter is the Primary_key of the table users, equivalent to Orm::factory (' user ')->where (' id ', ' = ', 1)->find ();
        $user _update = orm::factory (' user ', 1);
        The loaded method determines whether the load
        if ($user _update->loaded ()) {
            $user _update->name = ' Jack ';
            $user _update->save ();
        }
        Delete
        orm::factory (' user ', 1)->delete ();    }}? >

What is the ORM framework and what is the specific usage

ORM-that is object/relation Mapping
For detailed instructions see: baike.baidu.com/view/197951.htm

Presumably, this type of framework is designed to map class objects and relationships, creating a middle tier between application and database Io, and simply manipulating objects directly in the program (adding and removing objects from the database) rather than worrying about the columns of the tables in the database, relationships, whatever.

As an example:
Used to be a person at home to eat, need to buy rice to buy their own food, and then do their own, finished also have to clean up, feel good trouble, but also have to do, no way ah, bitter single-
This is equivalent to the traditional operating relationship (not using ORM);
And finally one day, found to eat in a restaurant is very convenient, do not worry about buying vegetables ah what, also do not worry about eating finish also have to pack a lot of what, order good food, eat good pay to leave on the line-what cook cooking things have someone else to do, specific people how to do, do not have tube--
This restaurant is the equivalent of an ORM mapping framework, for you to deal with those tedious and boring things, only the most important part--eat--let you do
And ordering is the equivalent of you do ORM mapping configuration, you tell the restaurant you want to eat something, the restaurant will be according to your needs to prepare for the dishes, ready to send you up!
