upgrade from 1.4.x to 2.1.2 datamapper installation. - El Forum - 10-09-2012

I thought I had followed the instructions closely for installing datamaper:
http://datamapper.wanwizard.eu/pages/installation.html
But I get this error:
Fatal error: Class 'bands' not found in /home/opendoor/public_html/classicgaragerock.com/application/libraries/datamapper.php on line 1072
Code:
line 1072 $this->{$name} = new $class();// bands is one of the tables that gets converted in datamapper.

Datamapper doesn't do anything with tables, it deals with models.
So that should autoload /application/models/bands.php, which should contain a class called "Bands" which must extend Datamapper.

You are quite correct. Forgive my inaccuracy.
Is this how my models should look?
Code:
<?php
class Band extends DataMapper {
var $has_many = array('song' => 'songs', 'file' => 'files');
var $has_one = array('label' => 'labels');
function Band($condition = array())
{
parent::DataMapper($condition);
}

No.
As shown here and on the next page, you would normally use
Code:
var $has_many = array('song', 'file');
var $has_one = array('label');If your models are defined non-standard, or you want the relation name to be different from the model name, you need the advanced relationship notation, as documented here.

Also,
What is the intention of this method:
Code:
function Band($condition = array())
{
parent::DataMapper($condition);
}If it's meant to be a constructor, use __construct() instead. You can't call parent:
atamapper, you have to call parent::__construct(), as documented here.And the constructor parameter is a numeric id, not an array...

Thank you that helps a lot.
My new error code is:
Fatal error: Class 'labels' not found in /home/opendoor/public_html/classicgaragerock.com/application/libraries/datamapper.php on line 1072
The only place I can find a reference to "labels" is in a file called "common_model.php" This file joins various tables.
Is it coded correctly for Datamapper?
[code
class Common_model extends DataMapper {
.
// let me know if you need to see this code
.
//------- CUSTOM --------//
function get_bands($iLimit = null, $iOffset = 0)
{
$oData = new stdClass;
$oData->total = $this->db->count_all_results('bands');
$this->db->select('bands.*, labels.name as label');
$this->db->from('bands');
$this->db->join('bands_labels', 'bands.id = bands_labels.band_id', 'left');
$this->db->join('labels', 'labels.id = bands_labels.label_id', 'left');
if (! is_null($iLimit)) $this->db->limit($iLimit, $iOffset);
$this->db->order_by('labels.name asc, bands.sort asc');
if ($query = $this->db->get())
{
$oData->result = $query->result();
$this->db->flush_cache();
return $oData;
}
return false;
}
function get_songs($iLimit = null, $iOffset = 0)
{
$oData = new stdClass;
$oData->total = $this->db->count_all_results('songs');
$this->db->select('songs.*, bands.name as band, labels.name as label');
$this->db->from('songs');
$this->db->join('bands_songs', 'songs.id = bands_songs.song_id', 'left');
$this->db->join('bands', 'bands.id = bands_songs.band_id', 'left');
$this->db->join('labels_songs', 'songs.id = labels_songs.song_id', 'left');
$this->db->join('labels', 'labels.id = labels_songs.label_id', 'left');
if (! is_null($iLimit)) $this->db->limit($iLimit, $iOffset);
$this->db->order_by('labels.name asc, bands.sort asc, songs.sort asc');
if ($query = $this->db->get())
{
$oData->result = $query->result();
$this->db->flush_cache();
return $oData;
}
return false;
}
}[/code]
Thank you so much for looking at this.

wasn't labels one of your relations?
And why do you have a datamapper model that does db calls? If your model doesn't implement Datamapper, you better extend CI_Model instead, it will save you some memory and CPU.

I inherited this site. It was working fine till my isp decided to update php to the latest version, and my side broke.
I am attempting to upgrade CI to the latest version. I saw DM files in my forensic reconstruction of the site.
There were calls for it in the legacy site...

If this was a CI 1.4 site, chances are it is even using Stensi's Datamapper. Which has been dead for several years, and mine isn't really compatible anymore (it's around since early 2009).
