php - EasyAdminBundle 实体表单字段自定义

Question

我试图在编辑表单中将标准的“created_at”字段设置为只读。正在关注the doc您必须添加以下配置:

    MyEntity:
        form:
            fields:
                - { property: 'created_at', type_options: { widget: 'single_text' } }

但它抛出以下错误:

An Exception was thrown while handling: The option "widget" does not exist. Defined options are: "action", "allow_extra_fields"...

是否有明显需要添加/修改的内容？

如果你想将字段设置为只读，你可能应该使用“禁用”选项:

MyEntity:
    form:
        fields:
            - { property: 'created_at', type_options: { disabled: true } }

如果这对您不起作用，您可以尝试明确设置表单类型吗？

MyEntity:
    form:
        fields:
            - { property: 'created_at', type: 'datetime', type_options: { widget: 'single_text' } }
