POMM2在Symfony3項目，註冊轉換器

Question

的想法是這樣的麻煩。在表'驅動程序'中，我有描述'驅動程序'的字段，但是我需要存儲另外一組大約100的字段，我不需要將其作爲表格列。所以我決定將它們存儲在Jsonb領域。我需要能夠使用這些領域作爲模型領域，但他們需要被自動保存在一個JSONB領域..當我從表中選擇我需要這個領域來顯示像表中的其他領域。

我已經檢查了有關文件轉換器和發現PgJson轉換器。所以我認爲這是處理這個問題的正確工具，但我目前還沒有設法正確配置。

我曾嘗試註冊場「testinfo」被註冊爲SessionBuilder轉換器類型「extrainfo」，但沒有成功。來自PG和PG的方法不被調用。這裏我展示了我的項目文件中的例子。

Answer 1

POMM的轉換器使用的字段類型來確定至極轉換器應該調用。你的領域應該是extrainfo。

創建這個新類型：

CREATE DOMAIN extrainfo AS jsonb; 

，並使用它的infodata列：

ALTER TABLE driver ALTER COLUMN infodata TYPE extrainfo;
