双重列表在 Symfony 1.4 嵌入表单中不起作用

问题描述 投票：0回答：1

我正在努力让一个简单的表单在 Symfony 1.4 后端模块中工作。

这个想法是创建一个嵌入式表单（一对多关系，Inschrijvingen -> Danser）。 每个嵌入表单都具有一对多的关系。 （Lessen）表单显示正确，但不保存 lessen_list。 （多对多关系）

我嵌入的 DanserForm 可以自行运行。 但将其嵌入到 InschrijvingenForm 中时不起作用。

我尝试了以下教程。 但这对我不起作用：http://inluck.net/Blog/Many-to-many-relations-in-embedded-form-in-Symfony-1_4

lessen_list
是您的
BaseDanserForm
和
BaseInchrijvingForm
类中的字段吗？ Symfony 通常提供一个小部件来管理多对多关系，就像您在基类中的关系一样。我只是以为它会被命名为
lessenvandanser_list
。

我认为您没有正确嵌入 Danser 表单。尝试类似于我在下面所做的操作，在使用这些 Danser 对象实例化嵌入表单之前，将 Danser 对象分配给 Inschrijving 对象。 我所做的是创建一个新的 DanserCollectionForm 类来处理此逻辑（见下文）。

// lib\form\DanserCollectionForm.class.php
class DanserCollectionForm extends sfForm
{
    if (!$inschrijving = $this->getOption('inschrijving')) {
        throw new InvalidArgumentException(sprintf("%s must be provided with inschrijving object", get_class($this)));
    }

    // Get all danser objects associated with this inschrijving
    $dansers = $inschrijving->getDansers();

    // If no dansers, then creat a new danser
    if (!$dansers) {
        $danser = new Danser();
        // Assign the danser to the inschrijving
        $danser->Inschrijving = $inschrijving;
        $dansers = array($danser);
    }

    // Embed Danser forms
    foreach ($dansers as $key => $danser) {
        $this->embedForm($key, new DanserForm($danser));
    }
}

然后在您的 InschrijvingForm 课程中 

// lib\form\InschrijvingForm.class.php 
class InschrijvingForm extends BaseInschrijvingForm
{
    public function configure()
    {
        unset(
            $this['created_at'],
            $this['updated_at'],
            $this['gestructureerde_mededeling']
        );

        $choices = CountryCodes::get();
        $this->widgetSchema['land'] = new sfWidgetFormChoice(array('choices' => $choices));

        $choice_keys = array();
        foreach ($choices as $choice) {
                $choice_keys = array_merge($choice_keys,array_keys($choice));
        }

        $this->setValidator('land', new sfValidatorChoice(array('choices' => $choice_keys, 'required' => true)));
        $this->setDefault('land','BE');

        $collectionForm = new DanserCollectionForm(null, array('inschrijving' => $this->getObject()));
        $this->embedForm('dansers', $collectionForm);
    }

    public function saveEmbeddedForms($con = null, $forms = null)
    {
        if (null === $forms) {
            $dansers = $this->getValue('dansers');
            $forms = $this->embeddedForms;

            foreach ($this->embeddedForms['dansers'] as $name => $form) {
                $deleteDanser = // Put logic of whether to ignore/delete danser forms here
                if ($deleteDanser) {
                    unset($forms['dansers'][$name]);
                    $form->getObject()->delete();
                }
            }
        }

        return parent::saveEmbeddedForms($con, $forms);
    }
}
