将 faker seeds 与 sequelize.js 一起使用：基于其他列值的列值

Question

function deptTypes(items) { 
  return items[Math.floor(Math.random()*items.length)]; 
}
var items = ["a", "b","c","d","e","f"]; 
await queryInterface.bulkInsert('reviews', [...Array(50)].map((review) => (
  {
    user_id: users[Math.floor(Math.random()*users.length)].id, 
    title: faker.name.title(), 
    review: faker.lorem.sentences(6), 
    rating: Math.round(Math.random()*5),
    department_type: deptTypes(items), 
    department_uid: (deptTypes(items) == 'a' ) ? alist[Math.floor(Math.random()*alist.length)].id 
                      :(deptTypes(items) == 'b' ) ? blist[Math.floor(Math.random()*blist.length)].id
                        : (deptTypes(items)== 'c') ? clist[Math.floor(Math.random()*clist.length)].id 
                          : (deptTypes(items) == 'd') ? dlist[Math.floor(Math.random()*dlist.length)].id
                            : (deptTypes(items) == 'e') ? elist[Math.floor(Math.random()*elist.length)].id
                              : flist[Math.floor(Math.random()*flist.length)].id, 
    created_at: new Date(),
    updated_at: new Date()
  }
)), {});

我正在尝试的是我需要分配给 department_type 的同一个 deptType 项目，并根据 department_type 给 department_uid 一个值，但我没有得到想要的结果。 .. 请帮忙

在 map 函数的顶部，声明一个变量，它将作为本次迭代的部门：

await queryInterface.bulkInsert('reviews', [...Array(50)].map((review) => {

  const dept = deptTypes(items);

  return {
    user_id: users[Math.floor(Math.random()*users.length)].id, 
    title: faker.name.title(), 
    review: faker.lorem.sentences(6), 
    rating: Math.round(Math.random()*5),
    department_type: dept,
    department_uid: (dept == 'a' ) ? alist[Math.floor(Math.random()*alist.length)].id 
                      :(dept == 'b' ) ? blist[Math.floor(Math.random()*blist.length)].id
                        : (dept == 'c') ? clist[Math.floor(Math.random()*clist.length)].id 
                          : (dept == 'd') ? dlist[Math.floor(Math.random()*dlist.length)].id
                            : (dept == 'e') ? elist[Math.floor(Math.random()*elist.length)].id
                              : flist[Math.floor(Math.random()*flist.length)].id, 
    created_at: new Date(),
    updated_at: new Date()
  };
}), {});

将 faker seeds 与 sequelize.js 一起使用：基于其他列值的列值
