php - Symfony3 项目中的 POMM2，注册转换器时遇到问题

Question

思路是这样的。在表“驱动程序”中，我有描述“驱动程序”的字段，但我需要存储另一组大约 100 个字段，我不需要将它们作为表列。所以我决定将它们存储在 Jsonb 字段中。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。当我从一个表中选择时，我需要这个字段像表中的其他字段一样显示。

我查看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，但到目前为止我没有设法以正确的方式配置东西。

我尝试将字段“testinfo”注册为类型“extrainfo”，该类型在 SessionBuilder 中注册为转换器，但没有成功。不会调用 fromPg 和 toPG 方法。在这里，我展示了我的项目文件中的示例。

Answer 1

Pomm 的转换器使用字段类型来确定应该调用哪个转换器。您的字段应该是 extrainfo。

创建这个新类型:

CREATE DOMAIN extrainfo AS jsonb;

并将其用于 infodata 列:

ALTER TABLE driver ALTER COLUMN infodata TYPE extrainfo;
