Question

我希望使用一些内置库（例如表单构建器）可以实现这一点。我有以下三个实体。中间的那个几乎只是一个常规的连接表，但它有一个额外的列，带有额外的数据。

公式 - ＆lt; FormulaColor＆gt; - 颜色

FormulaColor具有以下字段：公式，颜色和百分比。

百分比字段是指颜色构成给定公式的百分比。一个非常简单的例子是公式可能是77％红色和33％蓝色。我的问题是我想为公式选择颜色，并使用表格手动给它们一个百分比。所以我会添加（或编辑）某个公式并给它说紫色（20％）绿色（45％）和黄色（35％）。我不关心能否在公式添加/编辑视图中添加新颜色。我只是想能够选择现有的颜色。我一直在玩它几个小时收集和实体类型，但没有运气。

对我有任何指示或提示？如果没有表单组件等，我是否必须手动完成？

感谢。

我还有一个ColorAddEditType表格

class ColorAddEditType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('code', null, array(
                    'label' => 'Code'
                ))
            ->add('name', null, array(
                    'label' => 'Name'
                ))
        ;
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
                'data_class' => 'Prism\Portal\CommonBundle\Entity\Color'
            ));
    }

    public function getName()
    {
        return 'prism_portal_adminbundle_coloraddedittype';
    }
}

我还根据Ryan的回复更新了我的代码。

FormulaColorType

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('color', new ColorAddEditType());
    $builder->add('percent', 'number');
}

FormulaAddEditType

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('code', null, array(
                'label' => 'Code'
            ))
        ->add('name', null, array(
                'label' => 'Name'
            ));

    $builder->add('formulaColors', 'collection', array(
            'type' => new FormulaColorType(),
            'allow_add' => true,
            'allow_delete' => true,
            'prototype' => true,
        ));
}

现在我正在使用变换器/ set data_class来使异常为空。当我将一个更改为null时，它表示我可以将另一个更改为null。当我这样做时，它基本上会说要改回来。我应该为这样的事情设置数据转换器是正常的吗？

以下是我遇到的当前错误：

表单的视图数据应该是类的实例 Prism \ Portal \ CommonBundle \ Entity \ Color，但是是类的实例棱镜\门户\ CommonBundle \实体\ FormulaColor。你可以避免这种情况将“data_class”选项设置为null或添加视图时出错转换类实例的转换器 Prism \ Portal \ CommonBundle \ Entity \ FormulaColor为一个实例棱镜\门户\ CommonBundle \实体\颜色。

你应该可以做这样的事情。这是一种相当普遍的模式。棘手的一点是Javascript，但它不会太糟糕。您可能需要使用Javascript将数字添加到100。

<强> FormulaType

public function buildForm(FormBuilder $builder, array $options) {
    $builder->add('formulaColors', 'collection', array(
      'type' => new FormularColorType(),
      'allow_add' => true,
      'allow_delete' => true,
      'prototype' => true,
    ));
}

<强> FormulaColorType

public function buildForm(FormBuilder $builder, array $options) {
    $builder->add('color', new ColorType()); // Or similar
    $builder->add('percent', 'number');
}
