Each Model has a class to maintain the connection. Generally we creates all model class in below location:
/development/models
Each model as a Name that we used in class name as well as save in a member variable. Model class always extends appRain_Base_Model. See below example
// Model Name : page
// Class Name: pageModel
class pageModel extends appRain_Base_Model
{
public $name = "Page";
}
Model Version and Table Name is a vital entity to work with database. Assign false in $db_table if there is no database table to set. We save these values in below variables
public $version = "0.1.0";
public $name = "Page";
public $db_table = "pages";
A model can validate field data before we save. All validation role saved in below variable:
protected $model_validation = Array();
Model class can contain call back functions to execute on diffident event
Example of a Model:
class pageModel extends appRain_Base_Model
{
public $version = "0.1.0";
public $name = "Page";
public $db_table = "pages"; // Assign false if there is not table to set.
public $model_validation = Array();
public function _beforeSave($Model){
}
public function _afterSave($Model){
}
public function _onValidationSuccess($Model){
}
public function _onValidationFailed($Model){
}
}
