Symfony 4 类型：选项“0”不存在

Question

我找到了一个与我的问题类似的答案，但我不明白它是如何工作的，也不知道我应该在我的代码中更改什么。所以我向你求助，我有这个错误信息：

The option "0" does not exist. Defined options are: "action", "allow_extra_fields", "allow_file_upload", "attr", "auto_initialize", "block_name", "by_reference", "compound", "constraints", "csrf_field_name", "csrf_message", "csrf_protection", "csrf_token_id", "csrf_token_manager", "data", "data_class", "disabled", "empty_data", "error_bubbling", "error_mapping", "extra_fields_message", "help", "help_attr", "inherit_data", "invalid_message", "invalid_message_parameters", "label", "label_attr", "label_format", "mapped", "method", "post_max_size_message", "property_path", "required", "translation_domain", "trim", "upload_max_size_message", "validation_groups".

这是我的类型：

                    'choice_label' => 'name'
                ]
            ])

                ]
            ])
            ->add('rentExcludingCharges', NumberType::class, [
                'required' => true,
                'label' => 'Loyer hors charges'
            ])

            ->add('purchasePrice', NumberType::class, ['required' => true, 'label' => 'Prix d\'achat']);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Property::class,
        ]);
    }
}

希望你能理解我的英语并且有人能帮助我（并告诉我如何避免再次犯这个错误）

感谢

编辑：

中那些无用的 [] 有问题

->add('equipments', EntityType::class, [
            'required' => false,
            'label' => 'Equipements',
            [
                'class' => Equipment::class,
                'multiple' => true,
                'expanded' => true,
                'choice_label' => 'name'
            ]
        ])

，我解决了，但错误信息是一样的

Answer 1

我认为你的 [] 太少了:

->add('equipments', EntityType::class, [
            'required' => false,
            'label' => 'Equipements',
            //[
                'class' => Equipment::class,
                'multiple' => true,
                'expanded' => true,
                'choice_label' => 'name'
            //]
        ])

Answer 2

此处您缺少标签属性：

->add('description', TextType::class, ['required' => false, 'Description'])
