Question

I am creating a custom module.

I am testing the ability to update a products quantity.

I have created a bare bones magento module and began testing with code inside indexController.php here is my code:

public function indexAction() {

    //Just grabbing sku# 62701 for testing...
    $tempProduct = Mage::getModel('catalog/product')->loadByAttribute('sku', 62701 );

    $stockData['qty'] = 300;
    $tempProduct->setStockData($stockData);

    $tempProduct->save(); 

}

By having the last line in there i get the error.

From the error log:

a:5:{i:0;s:46:”Invalid method Varien_Object::save(Array
(
)

Followed by the stack trace…

Any help is appreciated, thank you.

I found a way to save data that seemed to work in my scenario (not sure why it worked) here:
https://stackoverflow.com/a/7608195/1110880

The code that made it work was the following:

    $productId = $tempProduct->getId();
    $stockItem = Mage::getModel('cataloginventory/stock_item')->loadByProduct($productId);
    $stockItem->setData('qty', $qty);

    $stockItem->save();

I hope this helps someone.
