How to fetch category products with all attributes in REST api

Question

There are categories in our store like featured and promotional. I fetch them in frontend by using there category id.Now I have fetch them through REST api.I made all the oauth configuration and set consumer successfully. So I have registered my module and added api2.xml. Added endpoint as /homepage/featured for featured products.

In V1.php

protected function _retrieveCollection() {
    $maincategory = Mage::getModel ( 'catalog/category' )->load ( 192 )->getProductCollection ();
    return $maincategory;
}

It is returning the product's but with less attributes.

How can I fetch all the product's attribute's from any category?

Answer 1

Use addAttributeToSelect(*)

protected function _retrieveCollection() {
    $maincategory = Mage::getModel ( 'catalog/category' )->load ( 192 )->getProductCollection ()->addAttributeToSelect('*');
    return $maincategory;
}
