You probably want the activerecord-postgres_enum gem, because it adds some good stuff for your migrations and allows you to keep using the schema.rb (instead of switching to a schema.sql:
gem 'activerecord-postgres_enum'Your migration would then look like this:
class AddCountryToCities < ActiveRecord::Migration[5.2]
| import async from 'async' | |
| export default class RetryQueue { | |
| constructor (strategy, opts = {}) { | |
| const options = Object.assign({ | |
| times: 14, | |
| interval (retryCount) { | |
| return 1000 * Math.pow(2, retryCount) | |
| } | |
| }, opts) |
| import mitt from 'mitt' | |
| const routeCache = new Map() | |
| const hotCache = new Map() | |
| const instanceCache = new Map() | |
| let latestRequest = null | |
| let isShowingPreview = false | |
| let prevRoute | |
| const eventBus = mitt() |
| import fsExtra from 'fs-extra' | |
| export default function jsonLog (filepath) { | |
| return async function (data) { | |
| await fsExtra.ensureFile(filepath) | |
| await fsExtra.appendFile(filepath, JSON.stringify(data) + '\n') | |
| } | |
