$callerClass = "imagenesGaleria",
$filter = "`GaleriaID` = '".$this->ID."'",
$sort = "",
$join = "",
$limit = "{$SQL_start},8"

[SOLVED]
this may help someone.
I find the way to render one Image (DataObject) of a gallery from the holder gallerys
My Class ImagenesGaleria:
class imagenesGaleria extends DataObject{
static $db = array (
'Title' => 'Varchar(250)',
);
static $has_one = array (
'Galeria' => 'Galeria',
'Photo' => 'Imagen',
);
public function getCMSFields_forPopup(){
return new FieldSet(
new TextField('Title'),
new FileIFrameField('Photo')
);
}
}My Class Galeria:
class Galeria extends Page {
static $has_many = array (
'FotosGal' => 'imagenesGaleria',
);
static $db = array(
);static $has_one = array(
);public function getCMSFields(){
$f = parent::getCMSFields();
$manager = new ImageDataObjectManager(
$this, // Controller
'FotosGal', // Source name
'imagenesGaleria', // Source class
'Photo', // File name on DataObject
array(
), // Headings
'getCMSFields_forPopup' // Detail fields
// Filter clause
// Sort clause
// Join clause
);
$f->addFieldToTab("Root.Content.Fotos",$manager);
return $f;
}
function forTemplate() {
$galeria = DataObject::get_one('imagenesGaleria', "GaleriaID = $this->ID");
return $galeria->renderWith('imagenesGaleria');
}
}class Galeria_Controller extends Page_Controller {
function fotos() { // to render al the images in the template Galeria.ss in the page type Galeria.
if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1) $_GET['start'] = 0;
$SQL_start = (int)$_GET['start'];
$doSet = DataObject::get(
$callerClass = "imagenesGaleria",
$filter = "`GaleriaID` = '".$this->ID."'",
$sort = "",
$join = "",
$limit = "{$SQL_start},8"
);
return $doSet ? $doSet : false;
}
}My Class imagenesGaleria:
class imagenesGaleria extends DataObject{
static $db = array (
'Title' => 'Varchar(250)',
);
static $has_one = array (
'Galeria' => 'Galeria',
'Photo' => 'Imagen',
);
public function getCMSFields_forPopup(){
return new FieldSet(
new TextField('Title'),
new FileIFrameField('Photo')
);
}
}And here is my holderGalerias.ss
<% control Children %>
<div class="thumb">
<a href="$Link" title="$Title"><img src="$Me" alt="" border="0" /></a>
<div class="title">$Title</div>
</div>
<% end_control %>Exist Me() method that returns $this, but if we use it in this case we will get this error.
Object->__call(): the method 'fortemplate' does not exist on 'Galeria'
for that i create the function forTemplate() inside the class Galeria:function forTemplate() {
$galeria = DataObject::get_one('imagenesGaleria', "GaleriaID = $this->ID");
return $galeria->renderWith('imagenesGaleria');
}witch get one image of the galeria and render with imagenesGaleria.ss, found in templates/Includes, with the following code:
$Photo.URL
Hopefully someone will understand my poor English
Bye.
