交响乐形式。既不是属性“TM”，也不是其中一种方法

构建表单时发生错误。

Neither the property "TM" nor one of the methods "getTM()", "isTM()", "hasTM()", "__get()" exist and have public access in class "Nitra\SchemaCDBBundle\Entity\MonthPlan.

错误在于它FormBuilder没有在 MonthPlan 实体类中找到任何方法或 TM 属性。但是我不明白他为什么要在 MonthPlan 实体中寻找这个方法。

我有一个班级MonthPlan，与员工的关系表示班级Employee

  /**
 * Сотрудник
 *
 * @ORM\ManyToOne(targetEntity="Employee", inversedBy="monthPlans")
 * @Assert\Type(type="Nitra\SchemaCDBBundle\Entity\Employee")
 */
protected $employee;

我需要为班级MonthPlan中的某些员工创建一个表格Employee。为此，我创建了一个类Form并声明了buildForm. 正如您在上次调用中看到的那样$builder->add()，我指定了选择员工所依据的类和查询以及显示结果所依据的属性'property' =>'name'，但最后我得到了上面指出的错误。

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

    $builder->add('chosenType', 'choice', array(
        'required' => true,
        'mapped' => false,
        'choices' => array(
            4 => 'fields.month.eta',
            2 => 'fields.month.TM'
        ),
        'label' => 'fields.month.typeEmployee',
        'translation_domain' => 'Admin'));

    $builder->add('TM', 'entity', array(
        'multiple' => false,
        'em' => 'default',
        'class' => 'NitraSchemaCDBBundle:Employee',
        'required' => false,
        'label' => 'fields.monthPlan.tm',
        'translation_domain' => 'Admin',
        'query_builder' => function(EntityRepository $er){
            return $er->createQueryBuilder('u')
                ->andWhere('u.lvl = :lvl')
                ->setParameter('lvl',2)
                ->addOrderBy('u.sureName','ASC');
        },
        'property' =>'name',
    ));

创建表单的完整代码。有一个父类EditType，里面是根据yml文件生成的。我继承并覆盖它buildForm

namespace Admingenerated\NitraEmployeeBundle\Form\BaseMonthPlanType;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use JMS\SecurityExtraBundle\Security\Authorization\Expression\Expression;

class EditType extends AbstractType
{
    protected $securityContext;

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

        $formOptions = $this->getFormOption('year', array(  'required' => true,  'mapped' => true,  'label' => 'fields.target.choseYear',  'translation_domain' => 'Admin',));
        $builder->add('year', new \Nitra\CommonBundle\Form\YearType(), $formOptions);


        $formOptions = $this->getFormOption('month', array(  'required' => true,  'mapped' => true,  'label' => 'fields.target.choseMonth',  'translation_domain' => 'Admin',));
        $builder->add('month', new \Nitra\CommonBundle\Form\MonthType(), $formOptions);


        $formOptions = $this->getFormOption('target', array(  'multiple' => false,  'em' => 'default',  'class' => 'Nitra\\SchemaCDBBundle\\Entity\\Target',  'required' => false,  'label' => 'fields.monthPlan.target',  'translation_domain' => 'Admin',));
        $builder->add('target', 'entity', $formOptions);


        $formOptions = $this->getFormOption('employee', array(  'multiple' => false,  'em' => 'default',  'class' => 'Nitra\\SchemaCDBBundle\\Entity\\Employee',  'required' => true,  'label' => 'fields.monthPlan.employee',  'translation_domain' => 'Admin',));
        $builder->add('employee', 'entity', $formOptions);


        $formOptions = $this->getFormOption('summ', array(  'precision' => 12,  'required' => true,  'label' => 'fields.monthPlan.summ',  'translation_domain' => 'Admin',));
        $builder->add('summ', 'number', $formOptions);


    }

    protected function getFormOption($name, array $formOptions)
    {
        return $formOptions;
    }

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

    public function setSecurityContext($securityContext)
    {
        $this->securityContext = $securityContext;
    }

}

我的自定义表单构建类。

    /**

     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);

        $builder->add('chosenType', 'choice', array(
            'required' => true,
            'mapped' => false,
            'choices' => array(
                4 => 'fields.month.eta',
                2 => 'fields.month.TM'

                    ->andWhere('u.lvl = :lvl')

    }

    protected function getFormOption($name, array $formOptions) {
        switch ($name) {
            case 'employee':
                $formOptions['query_builder'] = function (EmployeeRepository $er) {
                            return $er->getEmployeeAtPositionEta($this->securityContext->getToken()->getUser());
                        };
                break;
        }
        return $formOptions;
    }

}
