Typescript 如何在postgresql上存储typeorm的json对象数组？

我有一个假定包含json对象数组的用户实体，但我找不到typeorm本机存储的json数组类型，我不确定如何使用typeorm将它们存储在数据库中

当前的设置使用typegraphql，但我对它感到困惑

我的用户实体大致如下所示：

User.ts

import { Entity, PrimaryGeneratedColumn, Column, BaseEntity, ManyToOne } from "typeorm";
import { Field, Int, ObjectType, ID } from "type-graphql";


**//THIS ENTITY**
@ObjectType()
export class Softwares {
  @Field(() => Number)
  id: number;

  @Field()
  category: string;

  @Field(() => [String])
  list: string[];
}

@ObjectType()
export class About {
  @Field(  { nullable: true } )
  @Column("text", { nullable: true })
  about_header_message: string;

  **//THIS PART**
  @Field(() => [Softwares],  { nullable: true })
  softwares: Softwares[];

  @Field(() => [[String]],  { nullable: true })
  @Column("text", { nullable: true, array: true })
  info: string[][];
}

@ObjectType()
@Entity()
export class User extends BaseEntity {
  @Field(() => ID)
  @PrimaryGeneratedColumn()
  id: number;

  @Field({ nullable: true })
  @Column("text", { nullable: true })
  title_name: string;

  @Field({ nullable: true })
  @Column("text", { nullable: true })
  first_name: string;

  @Field({ nullable: true })
  @Column("text", { nullable: true })
  last_name: string;

  @Field((type) => About)
  @Column(() => About)
  about: About;
}

请注意，About类被继承到普通用户实体中。我这样做是因为get请求的最终GraphQL应该如下所示：

{
  title_name: "Sky Johnson",
  first_name: "Sky",
  last_name: "Johnson",
  about: {
    about_header_message: "A passionate developer, artist, and photographer",
    info: [
      ["University", "University of Colorado Boulder - Cumulative GPA: 3.376"],
      ["Graduation", "May Class of 2020"],
      ["Degree", "Computer Science (BS) - Degree GPA: 3.514"],
      ["2nd Degree", "Creative Technology and Design (BS) - Degree GPA: 3.657"],
      ["Minor", "Applied Mathematics: Theoretical Statistics"],
      ["Languages", "English: Native", "日本語：～N4 University Experience"],
    ],
    softwares: [
      {
        id: 1,
        category: "Favorite Languages",
        list: [
          "C# + Unity",
          "Python",
          "Java",
          "Scala",
          "Javascript/Typescript",
          "C/C++ (limited)",
          "Processing/Arduino",
          "OpenSCAD",
        ],
      },
      {
        id: 2,
        category: "Python Libraries",
        list: [
          "Tensor Flow",
          "MatPlotLib",
          "NetworkX",
          "Seaborn",
          "SciKit",
          "Keras",
        ],
      },
    ],
  },
};

我尝试在about类型的softwares字段的typeorm中使用manytone关系，但我无法使其工作，因为我认为用户上about类的继承性质将其搞乱（因为一个用户可以有许多软件对象，但软件列表在about实体中）

如果有人有任何想法，这将有很大帮助。谢谢

Typeform和Postgres支持

jsonb

字段

@Column('jsonb')
tasks: Foo[];

我想我是通过将软件实体拆分成一个新实体并使用`@manytone（（type）=>User，（User）=>User.about.softwares）调用多对一来解决这个问题的`
