    public function action_index() {
        $view = new View('userdetails/index');
        $this->response->body($view);
    }
     public function action_add() {
        $userdetails = new Model_Userdetails();         
        $view = new View('userdetails/adddetails');
        $view->set("userdetails", $userdetails);         
        $this->response->body($view);
    }

model is

userdetails.php

<?php defined('SYSPATH') or die('No direct script access.');

class Model_Userdetails extends ORM {

}

userinfo.sql

I am newly learning php and kohana.I am using kohana 3.2 version.I am following this tutorial to create,edit,update and delete data in database.I tried with above code,i am getting this error

"Database_Exception [ 1146 ]: Table 'kohana.userdetailses' doesn't exist [ SHOW FULL COLUMNS FROM `userdetailses` ]"   

need some help to solve this.

Answer 1

Kohana guesses the table name if $_table_name is not set. It pluralizes the model name as most of the time a model describes a single object, and the table describes a lot of them.

EDIT :

I saw you actually named your table userinfo and the model userdetails . If that is what you want:

class Model_Userdetails {

    protected $_table_name = 'userinfo';

    ........
}

Or alternatively rename the model to Model_Userinfo , or the table to userdetails and:

--- END EDIT ---

In your case it would seem most appropiate to:

class Model_Userdetails {

    protected $_table_name = 'userdetails';

    ........
}

Offcourse, you could alternatively rename your class to Model_Userdetail so that the table name will be guessed as userdetails

UPDATE :

Even though Kohana should guess these as well (ie SHOW FULL COLUMNS FOR table or sth), this might resolve the property not found error as discussed below in the comments.

protected $_table_columns = array(
    'id'        => array('type' => 'int'),
    'firstname' => array('type' => 'string'),
    ....... // repeat for all columns
);

Update:

There is a typo in your PHP code: deScription . Anyway, it is a good habit to define the table columns as this will save you an extra query every time a model is initialized for the first time. Along with some validation stuff which can take parameters from the array (eg the description of type TEXT is more or less not restricted in length, but you might want to limit it to say 2000 characters)
