带有外键约束的TypeORM QueryBuilder Insert Insert表

Question

我有两个表-组织和部门。departments表在organizationId列上具有组织的外键约束。显然，对于这两个表，我还有很多其他的外键关系。这只是一个用例。

在两个表上执行select语句可以很好地工作：

import "reflect-metadata";
import {createConnection} from "typeorm";
import {getConnection} from "typeorm";
import {Departments} from "./entity/Departments"

createConnection().then(async connection => {

    //get total estimated hours by month
    const departments = await getConnection()
        .createQueryBuilder( "Departments", "d")
        .innerJoinAndSelect("organizations", "o", "d.organizationId = o.organizationId")
        .select("organizationName, departmentName ")
        .where("d.organizationId = :organizationId", {organizationId: 2})
        .getRawMany();
    //  .getSql();

    console.log("Departments: ", departments);
}).catch(error => console.log(error));

当我尝试使用QueryBuilder插入部门时，organizationId未被识别为有效列：

import "reflect-metadata";
import {createConnection} from "typeorm";
import {getConnection} from "typeorm";
import {Departments} from "./entity/Departments"

createConnection().then(async connection => {

    //get total estimated hours by month
    await getConnection()
        .createQueryBuilder()
        .insert()
        .into(Departments)
        .values([
            { departmentName: "Test Product", organizationId: 2}
            ])
        .execute();
    //  .getSql();

}).catch(error => console.log(error));

以下是组织和部门的实体代码：

Organizations.ts -

import {
  Column,
  Entity,
  Index,
  OneToMany,
  PrimaryGeneratedColumn,
} from "typeorm";
import { Departments } from "./Departments";
import { Groups } from "./Groups";

import { Strategies } from "./Strategies";
import { Teammates } from "./Teammates";

  organizationId: number;

  @Column("varchar", { name: "organizationName", length: 100 })

  roadmapTemplates: RoadmapTemplates[];

  @OneToMany(() => Strategies, (strategies) => strategies.organization)
  strategies: Strategies[];

  @OneToMany(() => Teammates, (teammates) => teammates.organization)
  teammates: Teammates[];
}

Departments.ts

export class Departments {
  @PrimaryGeneratedColumn({ type: "int", name: "departmentId" })
  departmentId: number;

  @Column("nvarchar", { name: "departmentName", length: 100 })
  departmentName: string;

  @Column("int", { name: "ownerId", nullable: true })
  ownerId: number | null;

  @ManyToOne(() => Organizations, (organizations) => organizations.departments)
  @JoinColumn([
    { name: "organizationId", referencedColumnName: "organizationId" },
  ])
  organization: Organizations;

  @ManyToOne(() => Departments, (departments) => departments.departments)
  @JoinColumn([{ name: "parentId", referencedColumnName: "departmentId" }])
  parent: Departments;

  @OneToMany(() => Departments, (departments) => departments.parent)
  departments: Departments[];

  @OneToMany(() => Products, (products) => products.department)
  products: Products[];

  @ManyToMany(() => Programs, (programs) => programs.departments)
  @JoinTable({
    name: "programs_departments",
    joinColumns: [
      { name: "departmentId", referencedColumnName: "departmentId" },
    ],
    inverseJoinColumns: [
      { name: "programId", referencedColumnName: "programId" },
    ],
    schema: "dbo",
  })
  programs: Programs[];

  @OneToMany(() => Roadmaps, (roadmaps) => roadmaps.department)
  roadmaps: Roadmaps[];
}

不要紧--我想通了。即使在实体文件中正确定义了列关系，仍然需要添加@ ManyToOne引用。

@Column("int"，{ name："organizationId“}) organizationId:编号；
