Load Config Into Model

Yii 1.1 General Discussion

Hi,

I’m not sure what a good approach is for loading default settings into my model.

I have a model Image that extends CActiveRecord. It’s based on my table ‘image’ that hold all the information about uploaded images.

In this model I have a method that generates thumbnails. And i want to define the width and height of them in my main config.

In config/main.php I have something like:




	'params'=>array(

		'image'=>array(

			'thumbnail_sizes'=>array(

							array('width'=>235,'height'=>null),

							array('width'=>350,'height'=>null),

							array('width'=>705,'height'=>1200)

				),

In my model:




public $thumbnail_sizes;


function __construct()

{

    $this->thumbnail_sizes = Yii::app()->params['image']['thumbnail_sizes']

}

Is this how I should do this or is there a better way?

Hi,

I think you can put the variable directly. Why we should over ride the __construct?

Cheers!

Hi, how do you mean directly?

I’m still a beginner you know :) .

if the thumbnail_sizes is a fixed constant means

You can write the code directly as follows




class yourmodelclass extends CActiveRecord{

	public  $thumbnail_sizes = Yii::app()->params['image']['thumbnail_sizes'];




//Blah... blah...

is enough.

I thought this was not possible and indeed my editor gives me a syntax error…

Somebody could explain this to me?

You can also use init() method for set variable.


 public  $thumbnail_sizes;


      public function init()

	{

        $this->thumbnail_sizes= Yii::app()->params['image']['thumbnail_sizes'];

	}
