如何在cube.js 中处理postgres 数据库中的jsonb 对象？

Question

I have postgres database with a jsonb column which contains custom attribute keys and values. Is there any approach to get these to show up in the dimensions?

Answer 1

You can use ->> json operator for that https://www.postgresql.org/docs/9.5/functions-json.html . For example:

cube(`Users`, {
  sql: `select * from users`,

  // ...

  dimensions: {
    firstName: {
      sql: `${CUBE}.attributes->>'firstName'`,
      type: `string`
    },

    lastName: {
      sql: `${CUBE}.attributes->>'lastName'`,
      type: `string`
    }
  }
})
