php - Magento : Get data from Varien_Data_Collection -


hiho everybody! hope you'll give me clue because i'm still noob magento.

i try display list of products in array. in mage/catalog/block/product/list.php, created new varien_data_collection() in pushed products objects (with ->additem($product)).

then return custom collection , list.php class work display list of products.

when call page in browser, had right number of displayed products , when click on see product page, right page.

however, data (like product name, price, etc) empty. guess methods used list class catch these data fail varien_data_collection object.

to illustrate, here code sample :

// getting particular product $mainproduct = mage::getmodel('catalog/category')->load($currentcat->getid()); $mainproduct = $mainproduct->getproductcollection(); $mainproduct = $mainproduct->addattributetofilter('product_id', $_get['cat_id']);  // creating custom collection              $mycollection = new varien_data_collection();  foreach ($mainproduct $product) {     // getting particular product's related products in array     $related = $product->getrelatedproductids();                     if ($this->array_contains($related, $_get['cat_id'])) {         // if suits me, add in custom collection         $mycollection->additem($product);     } } return $mycollection;

and in list page :

enter image description here

when var_dump($mycollection), can see ['name'], ['price'], etc fields not referenced. ['product_id'] , many other fields don't care about.

my ultimate question : how can return collection containing these products data list class ? know poorly explained english limited , try best :(

calling ->getproductcollection() against category returns skeleton data each product in created collection. if want full data each of products, need load them, in foreach loop have:

$product = mage::getmodel('catalog/product')->load($product->getid());

however way in building collection not best working practice - should never have create own varien_data_collection object, instead should creating product collection follows:

$collection = mage::getmodel('catalog/product')->getcollection();

then before load collecion (which foreach loop or calling ->load() against collection 2 examples), can filter collection according requirements. can either using native magento methods, 1 of using (addattributetofilter()) or prefer pull select object collection , apply filtering way:

$select = $collection->getselect();

you can run of zend_db_select class methods against select object filter collection.

http://framework.zend.com/manual/1.12/en/zend.db.select.html

when collection has been loaded, products inside contain full product data.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
