[英]using faker seeds with sequelize.js: a column value based on the value of other column value
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()
}
)), {});
what i'm trying is i need the same deptType item that is assigned to department_type
and give department_uid
a value based on department_type
, but im not getting desired result ... please help我想要是我需要被分配到相同deptType项目department_type
并给予department_uid
基于值department_type
,但IM没有得到期望的结果...请帮助
At the top of the map function, declare a variable which will be the dept for this iteration:在 map 函数的顶部,声明一个变量,它将作为这次迭代的部门:
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() }; }), {});
