使用 sequelize 将 JSON 数据播种到 PostgreSQL 数据库时出错 [英] Error seeding JSON data with sequelize into PostgreSQL database
问题描述
在我运行 sequelize-cli 命令时发生 sequelize db:seed:all
Occurs when I run the sequelize-cli command sequelize db:seed:all
当我尝试将对象作为 JSON 播种时,我收到以下错误:
When I try and seed an object as JSON I get the following error:
ERROR: Invalid value { viewId: null,
dateRanges: [ { startDate: null, endDate: null } ],
samplingLevel: 'DEFAULT',
dimensions: [ { name: 'ga:channelGrouping' } ],
metrics: [ { expression: 'ga:users' } ] }
这是我的模特
module.exports = (Sequelize, DataTypes) => {
const Report = Sequelize.define('Report', {
name: {
type: DataTypes.STRING,
allowNull: false,
unique: true,
validate: {
is: /^[a-z0-9\_-]+$/i,
},
},
platform: {
type: DataTypes.STRING,
allowNull: false,
validate: {
is: /^[a-z0-9\_-]+$/i,
},
},
query: {
type: DataTypes.JSON,
},
});
return Report;
};
这是我的种子文件
'use strict';
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.bulkInsert('Reports', [
{
name: 'users per channel',
platform: 'google',
query: {
"viewId": null,
"dateRanges": [
{
"startDate": null,
"endDate": null,
},
],
"samplingLevel": "DEFAULT",
"dimensions": [
{
"name": "ga:channelGrouping",
},
],
"metrics": [{ "expression": "ga:users" }],
},
createdAt: new Date(),
updatedAt: new Date(),
},
]);
},
down: (queryInterface, Sequelize) => {},
};
我可以通过这个查询直接插入相同的数据
I was able to insert the same data directly with this query
INSERT INTO "Reports" (id, name, platform, query, "createdAt", "updatedAt") VALUES (1, 'users per channel', 'google', '{"viewId":null,"dateRanges":[{"startDate":null,"endDate":null}],"samplingLevel":"DEFAULT","dimensions":[{"name":"ga:channelGrouping"}],"metrics":[{"expression":"ga:users"}]}', '2018-04-15 08:55:12.449-05', '2018-04-15 08:55:12.449-05');
我找不到和我有同样问题的人,所以我相信这很简单,但我看不到.
I wasn't able to find anyone having the same issue as me so I believe it is something simple but I cannot see it.
如果我将对象包装在 JSON.stringify() 中,我可以毫无问题地运行种子,但这肯定不是预期的.
I'm able to run the seed with no problem if I wrap the object in JSON.stringify() but surely that isn't what is intended.
推荐答案
遇到同样的问题只需将您的 query
字段字符串化,例如
Encountered same problem
Just stringify your query
field like
'{
"viewId": null,
"dateRanges": [
{
"startDate": null,
"endDate": null,
},
],
"samplingLevel": "DEFAULT",
"dimensions": [
{
"name": "ga:channelGrouping",
},
],
"metrics": [{ "expression": "ga:users" }],
}'
@Jaygles 看看你的 sql
@Jaygles take a look at your sql
INSERT INTO "Reports" (id, name, platform, query, "createdAt", "updatedAt") VALUES (1, 'users per channel', 'google', '{"viewId":null,"dateRanges":[{"startDate":null,"endDate":null}],"samplingLevel":"DEFAULT","dimensions":[{"name":"ga:channelGrouping"}],"metrics":[{"expression":"ga:users"}]}', '2018-04-15 08:55:12.449-05', '2018-04-15 08:55:12.449-05');
您正在插入字符串化数据.所以你还需要在种子中对其进行字符串化
you are inserting stringified data. So you need also stringify it in seed
