How to set get('Items') limit?

Question

By default, populateState seems to limit a call to any model's get('Items') function to 20 items.

How can this be overridden - by re-writing populateState? By writing a separate function in the model? I've gone for the second option...

public function getAll(){
    return $this->_getList($this->getListQuery());
}

which works, but I think there's a more Joomla-ish way of doing this - I just can't find it.

Answer 1

To answer the question in the title about "setting" the limit, this is done in the Joomla global configuration: "Default List Limit".

To override, Joomla components generally seem to use this in the model: Using $limit = 0 shows all items

protected function populateState($ordering = null, $direction = null)
{
    // set limit
    $this->setState('list.limit', $limit);
    // set start (eg. what record to begin pagination at)
    $this->setState('list.start', $value);
}

Answer 2

Like others have said - put this in the model's populateState function

$this->setState('list.limit', $limit); #limit=0 removes limit
$this->setState('list.start', $start);

But you must make sure that these lines are AFTER

parent::populateState($order, $dir);

or the parent class will override your values

Answer 3

Try this also

protected function populateState($ordering = null, $direction = null)
    {
    // Load the list state.
    $this->setState('list.start', 0);
    $this->setState('list.limit', 10);
    }
