Can't get a grid to load in Admin - although the php is being parsed? What's wrong?

Question

Let's start with my adminhtml layout (where I think the issue is)

/app/design/adminhtml/default/default/layout/mattforms.xml

<?xml version="1.0"?>
<layout version="0.1.0">
<adminhtml_contacts_index>
    <reference name="content">
        <block name="grid" type="matt/adminhtml_contacts_grid"/>
    </reference>
</adminhtml_contacts_index>
</layout>

Block - /app/code/local/Shero/Matt/Block/Adminhtml/Contacts.php

<?php  
class Shero_Matt_Block_Adminhtml_Contacts extends Mage_Adminhtml_Block_Template 
{
    public function __construct() 
    {
        $this->_controller = 'adminhtml_contacts';
        $this->_blockGroup = 'matt';
        $this->_headerText = Mage::helper('Shero_Matt')->__('Contacts Manager');
        $this->_addButtonLabel = Mage::helper('Shero_Matt')->__('Add Contact');
        parent::_construct();
    }
}
?>

Grid Block - /app/code/local/Shero/Matt/Block/Adminhtml/Contacts/Grid.php

<?php
class Shero_Matt_Block_Adminhtml_Contacts_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
    public function __construct()
    {
        parent::_construct();
        $this->setId('contactsGrid');
        $this->setDefaultSort('id');
        $this->setDefaultDir('ASC');
        $this->setSaveParametersInSession(true);
    }
    protected function _prepareCollection()
    {
        $collection = Mage::getModel('matt/contacts')->getCollection();  
        $this->setCollection($collection);
        return parent::_prepareCollection();
    }
    protected function _prepareColumns()
    {
        $this->addColumn('id', array(
            'header' => Mage::helper('Shero_Matt')->__('ID'),
            'align'  => 'right',
            'width'  => '100px',
            'index'  => 'matt_contact_id',
        ));  
        $this->addColumn('firstName', array(
            'header' => Mage::helper('Shero_Matt')->__('Name'),
            'align'  => 'left',
            'width'  => '50px',
            'index'  => 'first_name',
        ));
        $this->addColumn('lastName', array(
             'header' => Mage::helper('Shero_Matt')->__('Last Name'),
            'align'  => 'left',
            'width'  => '50px',
            'index'  => 'last_name',
        ));
        return parent::_prepareColumns();
    }
}
?>

controller - /app/code/local/Shero/Matt/controllers/Adminhtml/ContactsController.php

<?php
class Shero_Matt_Adminhtml_ContactsController extends Mage_Adminhtml_Controller_Action
{
    public function indexAction()
    {
        $this->loadLayout();
        $this->renderLayout();
    }
    public function gridAction()
    {
        $this->loadLayout();
        $this->renderLayout();
    }
}
?>

                </contacts>
            </updates>
        </layout>
    </adminhtml>
</config>

What's important to note, if in Grid.php in my blocks, I change the a column from the database to be wrong, it throws the following:

'matt_contacts_id' in 'order clause', query was: SELECT `main_table`.* FROM `matt_contact` AS `main_table` ORDER BY matt_contacts_id ASC LIMIT 20

EDIT:

<block name="grid" type="matt/adminhtml_contacts_grid"/>

should also be

<block name="grid" type="matt/adminhtml_contacts"/>

in adminhtml layout for the grid container!

Your class Shero_Matt_Block_Adminhtml_Contacts is a Grid Container. Grid containers need to extend the class Mage_Adminhtml_Block_Widget_Grid_Container. It is this class that calls _prepareLayout() which instantiates your grid class.

Your __construct() method inside this class also calls parent::_construct() (note the single underscore instead of two underscores). It needs to call parent::__construct().

I hope this helps.

THANK YOU! You have no idea how long I spent on this trying to figure out where I went wrong. I was also, from your answer able to check and see that in my grid.php I needed to use __construct instead of _construct. – Matthew Clayton Feb 07 '15 at 06:17
