Question

我正在尝试使用liform或liform-bundle在我的控制器中生成我的表单类型的JSON，但收到错误：

CRITICAL - 未捕获的PHP异常Symfony \ Component \ Debug \ Exception \ UndefinedMethodException：“尝试调用类”Symfony \ Component \ Form \ Extension \ DataCollector \ Proxy \ ResolvedTypeDataCollectorProxy“的名为”getBlockPrefix“的未定义方法。” at /home/admin/Documents/displayce/code/vendor/limenius/liform/src/Limenius/Liform/FormUtil.php第39行

我控制器中的代码：

$form = $this->createForm(new FormType(), $entity, array(
        'method' => 'PUT',
        'csrf_protection' => false, 
    ));
$schema = json_encode($this->get('liform')->transform($form));

我的表单类型代码：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder

        ->add('startDate', 'date', array(
            'label' => 'Start Date',
            'required' => false,
            'widget' => 'single_text',
            'format' => 'dd/MM/yyyy',
            'input' => 'datetime',
        ))
        ->add('endDate', 'date', array(
            'label' => 'End Date (included)',
            'required' => false,
            'widget' => 'single_text',
            'format' => 'dd/MM/yyyy',
            'input' => 'datetime',
        ))
        ->add('name', 'text', array(
            'label' => 'Name',
            'max_length' => 255,
        ))
        ->add('budget', 'money', array(
            'label' => 'Budget (target)',
            'required' => true,
            'scale' => 0, // not showing decimals
        ))
        ->add('target', 'targeting', array(
            'cascade_validation' => true,
        ));
}

和定位类型：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('contexts', 'entity', array(
            'label' => 'Context(s)',
            'class' => 'AppBundle\Entity\Context',
            'choice_label' => 'name',
            'expanded' => false,
            'multiple' => true,
            'required' => false,
        ))
        ->add('contextDetails', 'entity', array(
            'label' => 'Detailed Context(s)',
            'class' => 'AppBundle\Entity\ContextDetail',
            'choice_label' => 'name',
            'group_by' => 'context.name',
            'expanded' => false,
            'multiple' => true,
            'required' => false,
        ))
        ->add('dataVariables', 'entity', array(
            'label' => 'Variable',
            'class' => 'AppBundle\Entity\DataVariable',
            'choice_label' => 'name',
            'expanded' => false,
            'multiple' => true,
            'group_by' => function($dataVariable, $key, $index) {
                return $dataVariable->getDataProvider()->getName();
            }
        ))

        // Include criteria
        ->add('region', 'choice', array(
            'label' => 'Region(s)',
            'choices' => RegionDepartment::$regions,
            'expanded' => false,
            'multiple' => true,
            'required' => false,
        ))
        ->add('department', 'choice', array(
            'label' => 'Department(s)',
            'choices' => RegionDepartment::$departments,
            'expanded' => false,
            'multiple' => true,
            'required' => false,
        ))
    ;

可能是因为我使用嵌套的formtype？

我的目标是将symfony FormType与React Component结合起来，只要您可以将我重定向到解决方案来做到这一点，我会很高兴。

Answer 1

将getBlockPrefix添加到您的formType和定位类型，如下所示：

  val mDF: DataFrame = spark.read.option("header", "true").option("inferSchema", "true").csv("src/test/resources/knimeMergedTRimmedVariables.csv")
  val mDFTyped = castAllTypedColumnsTo(mDF, IntegerType, DoubleType)

  val indexer = new StringIndexer()
    .setInputCol("Majors_Final")
    .setOutputCol("Majors_Final_Indexed")
  val mDFTypedIndexed = indexer.fit(mDFTyped).transform(mDFTyped)
  val mDFFinal = castColumnTo(mDFTypedIndexed,"Majors_Final_Indexed", IntegerType)

  mDFFinal.show()
  //only doubles accepted by sparse vector, so that's what we filter for
  val fieldSeq: scala.collection.Seq[StructField] = mDFFinal.schema.fields.toSeq.filter(f => f.dataType == DoubleType)
  val fieldNameSeq: Seq[String] = fieldSeq.map(f => f.name)

  var positionsArray: ArrayBuffer[LabeledPoint] = ArrayBuffer[LabeledPoint]()

  mDFFinal.collect().foreach
  {

    row => positionsArray+=convertRowToLabeledPoint(row,fieldNameSeq,row.getAs("Majors_Final_Indexed"));

  }

  val mRdd:RDD[LabeledPoint]= spark.sparkContext.parallelize(positionsArray.toSeq)

  MLUtils.saveAsLibSVMFile(mRdd, "./output/libsvm")

Answer 2

我将bundle更改为 - ＆gt; getBlockPrefix为 - ＆gt; getName（），因为第一个不在Symfony 2.7中的Form.php中

获取我的FormType架构的JSON
