Am trying to fetch the Project Name from Project Details table data is getting and project id saving in Timeline table but i can't set Product name in summary fields if anyone have the solution please help me . Thanks in Advance.!
is there any syntax issue in this codes? like has many, has one , many many ?
These are my codes
ProjectTimeline.php
class ProjectTimeline extends DataObject {
private static $table_name = 'ProjectTimeline';
private static $db = [
'Title' => "Varchar(255)",
'ProjectId' => "Varchar(255)"
];
private static $has_one = [
'ProjectPage' => ProjectPage::class
];
private static $has_many =[
'ProjectDetails'=>ProjectDetails::class
];
/**
* Data Listing Fields
*/
private static $summary_fields = [
'ProjectDetails.ProjectName' => 'Project Name',
'Title' => 'Title'
];
private static $extensions = [
Versioned::class,
];
private static $versioned_gridfield_extensions = true;
/**
* getCMSFields
* Projects - Amenities Form Fields
*
* @return void
*/
public function getCMSFields()
{
return new FieldList(
DropdownField::create('ProjectId', 'Link a Product', ProjectDetails::get()->map('ID', 'ProjectName')),
TextField::create('Title')
);
}
/**
* Search Fields
*/
private static $searchable_fields = [
'Title'
];
/**
* getCMSValidator - Required Fields
*
* @return void
*/
public function getCMSValidator()
{
return new RequiredFields([
'Title'
]);
}
ProjectDetails.php
private static $has_one = [
'ProjectPage' => ProjectPage::class,
'QuickFactsImage' => Image::class,
'ProjectTimeline' => ProjectTimeline::class
];
private static $many_many = [
'ProjectImage' => Image::class,
'FloorTypesImage' => Image::class
];
Unfortulantely this is not built into Silverstripe. A has_many relation will return a HasManyList, a subclass of DataList. You'll have to provide a getter method in your ProjectTimeline DataObject to loop over that list and concat the project names like:
public function getProjectDetailsNames()
{
$names = $this->ProjectDetails()->column('ProjectName'); //returns just that column as an array
return implode(', ' $names);
}
Then you can use this method in summary_fields:
private static $summary_fields = [
'getProjectDetailsNames' => 'Project Names',
'Title' => 'Title'
];
I hope that helps you solving that problem!
