Magento: Get record of my model by custom Field

Question

Is it possible to get a record of my model by another field of my model?

The normal way

$model = Mage::getModel('foo_bar/baz');
$model->load($id);
// do something with the loaded record

But i need something like this

$model = Mage::getModel('foo_bar/baz');
$model->loadByAnotherFieldOfModel($value)
// do something with the loaded record

is that possible?

Answer 1

$model = Mage::getModel('foo_bar/baz');
$model->load('field_value', 'field_name');

Answer 2

use this

$_category = Mage::getModel('catalog/category')->loadByAttribute('name', 'computer');  
$_product = Mage::getModel('catalog/product')->loadByAttribute('name', 'hp2312');  

// Load by SKU  
$_product = Mage::getModel('catalog/product')->loadByAttribute('sku', 'computer123');
