    { 
        parent::_construct();

        $this->_init('banners/category');

    }
}

So how to run this and how this model resource know about has table..?

Answer 1

If you want to add another model to your custom module, you should enter your table name in config.xml file, which is located in yourmodule/etc folder:

<entities>
<banners>
    <table>Your table Name here</table>
</banners>

After that you should add your collection class in corresponding model/mysql4/category/Collection.php. You should create model class in model/file name.

Suppose category.php is the model file, you should initiate that model class by using these methods. These files should be in the model folder:

public function _construct()
{    
    // Note that the category_id refers to the key field in your database table.
    $this->_init('banner/category', 'category_id');
}
