Question

我的symfony2项目中出现此错误：

表单的视图数据应该是类Sub rename() Dim sName As String sName = Application.InputBox _ (Prompt:="Enter new worksheet name") Range("C4").Validation.Delete On Error Resume Next ActiveWorkbook.SaveAs ActiveWorkbook.Path & "\" & sName & ".xlsm", ConflictResolution:=xlUserResolution On Error GoTo 0 End Sub的实例，但是是类Proyecto\AdminBundle\Entity\Unidades的实例。您可以通过设置＆＃34; data_class＆＃34;来避免此错误。 null的选项或添加视图转换器，将类Proyecto\AdminBundle\Entity\Catalogo的实例转换为Proyecto\AdminBundle\Entity\Catalogo的实例。

避免使用getter，setter和实体属性等几件事。

Catalogo.php

Proyecto\AdminBundle\Entity\Unidades

Unidades.php

    class Catalogo
    {
     /**
     * @ORM\OneToMany(targetEntity="Unidades", mappedBy="catalogo")
     */
    protected $unidades;

    public function __construct()
    {
        $this->unidades = new ArrayCollection();
    }

    public function getUnidades()
    {
        return $this->unidades;
    }

    public function setUnidades($unidades)
    {
        $this->unidades[] = $unidades;
        foreach ($unidades as $unidad) {
        $unidad->setCatalogo($this);
        }
    }

CatalogoUnidadesType.php

class Unidades

    /**

    protected $catalogo;

   /**
     * Set catalogo
     *
     * @param float $catalogo
     * @return Unidades
     */
    public function setCatalogo($catalogo)
    {
        $this->catalogo = $catalogo;

        return $this;
    }

    /**

Answer 1

您应该构建一个名为b的类，其中包含CatalogoUnidades和Catalog，然后为其创建一个FormType。

我希望这会有所帮助。
