我在项目中设置many_many_extraFields
之后某些DataObjects之间的<?php
// Definizione Namespace
use SilverStripe\ORM\DataObject;
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\TextField;
use SilverStripe\Forms\NumericField;
use SilverStripe\Forms\DropdownField;
use SilverStripe\Forms\GridField\GridField;
use SilverStripe\Forms\GridField\GridFieldConfig_RelationEditor;
use SilverStripe\Forms\RequiredFields;
use SilverStripe\Security\Permission;
/**

*/
class Sconto extends DataObject
{
[...]
private static $many_many = [
'Regole' => 'Regola'
];
private static $many_many_extraFields = [
'Regole' => [
'Area' => 'Varchar',
'Tipologia' => 'Varchar',
'Prezzo' => 'Currency'
]
];
[...]
/**
* Metodo gestione campi CMS
* Setter
* @return FieldList $fields Campi Back-End
*/
public function getCMSfields()
{
$fields = parent::getCMSFields();
[...]
// Fetching campi Regole
$regolaFields = singleton('Regola')->getCMSfields();
// Aggiunta campi specifici Regole
$regolaFields->addFieldsToTab('Root.Regola', array(
DropdownField::create('ManyMany[Area]', 'Area di applicazione', array(
'Prodotto' => 'Prodotto'
))->setEmptyString('Applica a'),
DropdownField::create('ManyMany[Tipologia]', 'Criterio di applicazione', array(
'Prezzo' => 'Prezzo'
))->setEmptyString('Applica per'),
NumericField::create('ManyMany[Prezzo]', 'Prezzo prodotto (€)')->setScale(2)->setAttribute('placeholder', 'Es. 5,00')
), 'Criterio');
$configRegole = GridFieldConfig_RelationEditor::create();
$configRegole->getComponentByType('GridFieldDetailForm')->setFields($regolaFields);
$gridRegole = GridField::create('Regole', 'Regole', $this->Regole(), $configRegole);
$fields->findOrMakeTab('Root.Sconto')->replaceField('Regole', $gridRegole);
[...]
return $fields;
}
}
关系。
使用以下代码:
$configRegole->getComponentByType('GridFieldDetailForm')->setFields($regolaFields);
framweork抛出这个例外:
[Alert]在null
上调用成员函数setFields()
参考这一行:
{col:df[col].dropna().to_dict() for col in df}
正如您所看到的,我在其之前添加了规范实例化 - 例如开发人员指南建议。
我正在试图弄清楚原因是什么,但我确信缺少某些东西。
提前致谢。
答案 0 :(得分:2)
您需要使用其完全限定的类名引用GridFieldComponent类。这也适用于SS4中的任何类,如果您养成使用::class
引用它们的习惯,则更容易使用,例如: Regola::class
即使他们没有自己的命名空间。
正确的代码:
use SilverStripe\Forms\GridField\GridFieldDetailForm;
// ...
$configRegole->getComponentByType(GridFieldDetailForm::class)->setFields($regolaFields);
