没有显示Symfony3表单错误（只是notNull / notBlank），其余的都在工作

Question

我尝试验证symfony3表单，我为每个实体字段使用两个约束（NotBlank和Float）。浮动约束的错误消息正确显示，因为NotBlank错误消息仅针对整个表单（全局错误）显示，而不是针对每个分离的字段。我也尝试使用NotNull而不是NotBlank，这对我没用。

Bellow我已经复制/粘贴了一段代码。

class ParametersType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('variable_sheer_header',  NumberType::class, [
                'label' => 'parameters.variable_sheer_header',
                'error_bubbling' => true ,
                'attr' => [
                    'placeholder' => 'parameters.variable_sheer_header',
                    "class" => 'form-control'
                ],
            ])
            ->add('variable_sheer_hem',     NumberType::class, [
                'label' => 'parameters.variable_sheer_hem',
                'error_bubbling' => true ,
                'attr' => [
                    'placeholder' => 'parameters.variable_sheer_hem',
                    "class" => 'form-control'
                ],
            ])
            ->add('variable_sheer_overlap', NumberType::class, [
                'label' => 'parameters.variable_sheer_overlap',
                'error_bubbling' => true ,
                'attr' => [
                    'placeholder' => 'parameters.variable_sheer_overlap',
                    "class" => 'form-control'
                ],
            ])

您希望在表单中使用required as true属性。
