这个想法是这样的。在表＆＃39;驱动程序＆＃39;我有描述＆＃39; driver＆＃39;的字段，但是我需要存储另外一组大约100个字段，我不需要将它们作为表格列。所以我决定把它们存放在Jsonb领域。我需要能够将这些字段作为模型字段使用，但它们需要自动保存在一个jsonb字段中。当我从表中选择时，我需要将该字段显示为与表中的其他字段一样。
我检查了有关转换器的文档并找到了PgJson转换器。所以我认为这是处理这个问题的正确工具，但到目前为止我还没有设法以正确的方式配置。
我试图注册字段＆＃39; testinfo＆＃39;作为类型＆＃39; extrainfo＆＃39;它在SessionBuilder中注册为转换器，但没有成功。不调用fromPg和toPG的方法。这里我展示了我的项目文件中的示例。

答案 0 :(得分：1)
Pomm的转换器使用字段类型来确定它应该调用的转换器。您的字段应为extrainfo。
创建这种新类型：
CREATE DOMAIN extrainfo AS jsonb;
并将其用于infodata列：
ALTER TABLE driver ALTER COLUMN infodata TYPE extrainfo;
