EasyAdminBundle實體表單字段自定義

Question

我試圖在編輯表單中只創建一個標準的「created_at」字段。繼the doc你必須添加以下配置：

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

但它引發以下錯誤：

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

有什麼明顯的添加/修改？

如果你想使字段只讀的，你應該使用「已禁用」選項：

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

如果這不適合你，你可以嘗試明確設置表單類型？

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