Question

I have a static method ‘findAll’ on a model which basically gets all rows with certain criteria. This method works fine and I can call it using:

$m::findAll();

Where $m is the model name as a variable. I can output this and it returns correct results. However, when assigning this to a variable in the Zend_View object, as:

$this->view->viewvariable = $m::findAll();

I get the error:

Zend_Db_Table_Exception: Too many
columns for the primary key

Any ideas why?

Find all function:

final public static function findAll($where = false, array $options = array()) {
  $object = new static();

  if (!empty($options)) $options = array_merge($object->options, $options);
  else $options = $object->options;

  $run = $object->buildDefaultSelect($where, $options);
  $rows = $run->fetchAll();
  if ($options['asObject'] == true) {
   $result = array();
   foreach ($rows as $r) {
    $class = new static();
    $class->setInfo($r);
    $result[] = $class;
   }
   return $result;
  } else {
   if (count($rows) > 0) return $rows;
   else return array();
  }
 }

Note: This function works fine everywhere apart from when assigning to a view variable. If I run the below (not assigning it to a view variable), it shows the correct array data.

   var_dump($m::findAll($module['where'], $module['options']));
   exit;

In my view (I have replaced the actual name with viewvariable for the sake of this post):

<?php foreach($this->viewvariable as $item) { ?>
//Do some echoing of data in $item
//Close foreach

I doubt the issue is with Zend_View. It’s hard to tell without seeing your code, but my guess is that findAll() is using the Zend_Table_Db find() function incorrectly.

To my knowledge, the only place that throws that exception is the find() function on Zend_Db_Table_Abstract.

Perhaps, inside the findAll() function (or in a function it calls) you’re doing one of these:

$zendDbTable->find(1,2) //is looking for a compound key
$zendDbTable->find(array(1,2)) //is looking for two rows

When you really want the opposite.
