I have few problems when try make a plugin.

This is my code:

**Mibloque.php

class Uniagro_Tpv_Block_Mibloque extends Mage_Core_Block_Template
{
    public function methodblock()
    {
        //return "informations about my block !!" ;
        //on initialize la variable
        $retour='';
        /* we are doing the query to select all elements of the pfay_test table (thanks to our model test/test and we sort them by id_pfay_test */
     $collection = Mage::getModel('tpv/tpv')->getCollection()->setOrder('id','asc');
         /* then, we check the result of the query and with the function getData() */
        foreach($collection as $data)
        {
             $retour .= $data->getData('banco').' '.$data->getData('codigotienda')
                     .' '.$data->getData('url').'<br />';
         }
         //i return a success message to the user thanks to the Session.
         Mage::getSingleton('adminhtml/session')->addSuccess('Cool Ca marche !!');
         return $retour;      
    }
}

** config.xml

              </connection>
            </tpv_read>
        </resources>
    </global>
</config>

** model/Tpv.php

class Uniagro_Tpv_Model_Tpv extends Mage_Core_Model_Abstract
{
     public function _construct()
     {
         parent::_construct();
         $this->_init('tpv/tpv');
     }
}

** model/Mysql4/Tpv.php

class Uniagro_Tpv_Mysql4_Tpv extends Mage_Core_Model_Mysql4_Abstract
{
    public function _construct()
    {
        $this->_init('tpv/tpv', 'id');
    }
}

I'm try some solutions (for example this [fatal error: Call to a member function getCollection() on a non-object in magento

[1]: fatal error: Call to a member function getCollection() on a non-object in magento ) but always send my the same error "Fatal error: Call to a member function setOrder()"

And i review my bd and have the column to order ('id')

2

Add model collection class and try

class Uniagro_Tpv_Mysql4_Tpv_Collection extends Mage_Core_Model_Mysql4_Collection_Abstract{
    public function _construct(){
        $this->_init('tpv/tpv');
    }
}

Edit (As result of the comments):

The Problem was the wrong named/placed class Uniagro_Tpv_Mysql4_Tpv which belongs into the Model area so it has to be Uniagro_Tpv_Model_Mysql4_Tpv

  • Thanks for your answer, but i try to put this code but, have the same error :S – Marcos Feb 26 '14 at 12:32
  • have you created the table – Helphin Feb 26 '14 at 12:37
  • Yes, I have the table in my bd and exists the column to the order ('id'), if need more code i can write – Marcos Feb 26 '14 at 12:42
  • class Uniagro_Tpv_Mysql4_Tpv extends Mage_Core_Model_Mysql4_Abstract missing model class, (ie) Uniagro_Tpv_Mysql4_Tpv to Uniagro_Tpv_Model_Mysql4_Tpv – Helphin Feb 26 '14 at 12:44
  • Hey! Thanks for your help! I found it my error....the problem is the PHP for Mysql4/Tpv/Collection.php...i delete this file and I write again and success! Thanks for all! – Marcos Feb 26 '14 at 12:53

This should work.

$collection = Mage::getModel('tpv/tpv')->getCollection();
$collection->getSelect()->order('main_table.id ASC');
  • Thanks for response, but don't work...This code give me the error " Fatal error: Call to a member function getSelect() on a non-object" – Marcos Feb 26 '14 at 12:34
  • This won't work because in the OP's case getCollection() returns null. – Marius Feb 26 '14 at 12:46
  • Hey! Thanks for your help, I found my problem...its for the Collection file, i delete this and make again and it's Ok! Thanks again! – Marcos Feb 26 '14 at 12:54
