using DataObject::get() to fill dropdown in getCMSFields_forPopup()
22 August 2008 at 1:04am
I have created these two classes, but I would like to populate the dropdown in Project from another DataObject table that can be edited inside a tab in ProjectHolder.
class ProjectHolder extends Page {
static $db = array(
);
static $has_one = array();
static $has_many = array(
'Projects' => 'Project'
);function getCMSFields() {
$fields = parent::getCMSFields();$tablefield = new HasManyComplexTableField(
$this,
'Projects',
'Project',
array(
'title' => 'Title',
'manager' => 'Manager'
),
'getCMSFields_forPopup'
);
$tablefield->setAddTitle( 'A Project' );$fields->addFieldToTab( 'Root.Content.Projects', $tablefield );
return $fields;
}
}class Project extends DataObject {
static $db = array(
'title' => 'Text',
'manager' => "Enum('Manager1, Manager2')"
);static $has_one = array(
'MyProjectHolder' => 'ProjectHolder'
);function getCMSFields_forPopup() {
$fields = new FieldSet();
$fields->push( new TextField( 'title' ) );
$map = array('1' =>'Manager1','2' => 'Manager2');
$fields->push( new DropdownField(
'manager',
'manager of project',
$map)
);
return $fields;
}}

So you want to populate the 'Managers' list on Project.php from a seperate 'Managers' DataObject? Well What you would need to do is create a Managers DataObject first off, then a project has one Manager. Then I think you can call toArray() on a dataobjectset. So you would have
class Project extends DataObject {
static $db = array(
'title' => 'Text',
);static $has_one = array(
'MyProjectHolder' => 'ProjectHolder',
'Manager' => 'Manager'
);function getCMSFields_forPopup() {
$fields = new FieldSet();
$fields->push( new TextField( 'title' ) );
$managers = DataObject::get("Manager")->toArray();
$fields->push( new DropdownField(
'manager',
'manager of project',
$managers)
);return $fields;
}}
That would be your project code. You would also then need a Manager.php dataobject.

i'm still having a bit of trouble with this, as it is not populating the dropdown box with the contents of DataObject::get("Manager"), but merely giving one option, "Manager". The second problem is that even if this only option "Manager" is chosen it doesn't save - before I had
'manager' => "Enum('Manager1, Manager2')"
in $db.my files now look thus:
<?php
class Project extends DataObject {
static $db = array(
'title' => 'Text',
'manager' => 'Text'
);static $has_one = array(
'MyProjectHolder' => 'ProjectHolder',
'Manager' => 'Manager'
);function getCMSFields_forPopup() {
$fields = new FieldSet();
$fields->push( new TextField( 'title' ) );
$managers = DataObject::get("Manager")->toArray();
$fields->push( new DropdownField(
'manager',
'manager of project',
$managers)
);
return $fields;
}}
?>
<?php
class Manager extends DataObject {
static $db = array(
'Name' => 'Text'
);static $has_one = array(
'MyProjectHolder' => 'ProjectHolder'
);static $has_many = array(
'MyProject' => 'Project'
);function getCMSFields_forPopup() {
$fields = new FieldSet();
$fields->push( new TextField( 'Name' ) );
return $fields;
}}
?>
<?php
/**
* Defines the ProjectHolder page type
*/
class ProjectHolder extends Page {
static $db = array(
);
static $has_one = array();
static $has_many = array(
'Projects' => 'Project',
'Managers' => 'Manager'
);function getCMSFields() {
$fields = parent::getCMSFields();$tablefield = new HasManyComplexTableField(
$this,
'Projects',
'Project',
array(
'title' => 'Title',
'manager' => 'Manager'
),
'getCMSFields_forPopup'
);
$tablefield->setAddTitle( 'A Project' );$managertablefield = new HasManyComplexTableField(
$this,
'Managers',
'Manager',
array(
'name' => 'Name',
),
'getCMSFields_forPopup'
);
$managertablefield->setAddTitle( 'A Manager' );$fields->addFieldToTab( 'Root.Content.Projects', $tablefield );
$fields->addFieldToTab( 'Root.Content.Managers', $managertablefield );
return $fields;
}
}class ProjectHolder_Controller extends Page_Controller {
}
perhaps i'm doing something wrong? -

Well one of the issues that its not saving is because we defined a has_one relation on Project -> manager we dont need the manager database field (in the $db array) Instead the has_one automatically creates a FieldNameID database column we want to save into for the has_one so you would need to change the dropdown constructor
$fields->push( new DropdownField(
'ManagerID',
'manager of project',
$managers)
);as for only 1 manager showing up you might just like to do a Debug::show($managers); after the DataObject() call and see what it returns. See if anythings amiss

It still wont save, but I do get 2 options now, but they appear as "Manager" still in the dropdown. Here is the output of Debug::show($managers);
Debug (Project->getCMSFields_forPopup() in line 18 of Project.php)

I have sorted the problem with getting the dropdown populated thanks to your tip about debug, but I still have the problem that it doesn't save the dropdown selection - title is save but manager stays blank. Here is my code:
<?php
class Project extends DataObject {
static $db = array(
'title' => 'Text'
);static $has_one = array(
'MyProjectHolder' => 'ProjectHolder',
'Manager' => 'Manager'
);function getCMSFields_forPopup() {
$fields = new FieldSet();
$fields->push( new TextField( 'title' ) );
$managers = DataObject::get("Manager");
$map = $managers->toDropDownMap('ID', 'Name');
$fields->push( new DropdownField(
'ManagerID',
'manager of project',
$map)
);
return $fields;
}}
?>

hmm strange. If you look at the source code of the drop down is there a 'value="X"' in each option field? eg is there something to save
