Alias Rails columns

Snippet kitt decided around 16:34 on 6 July 2022 to publish this:

When working with APIs, sometimes the fields from the APIs are reserved keywords (looking at you, Shopify, and your type fields). When saving the data directly, you don't can't have a field in the database named type, but you don't want to manipulate the parameters and models for every query call. That would suck.

Alias the field instead.

class User < Activerecord::Base
  alias_attribute :new_column_name, :real_column_name
end
 
# specific use case (metafields at Shopify)
ActiveRecord::Schema.define(version: 2022_07_04_191939) do
  create_table "metafields", force: :cascade do |t|
    t.string "namespace"
    t.string "key"
    t.string "value"
    t.string "value_type"
    t.string "variant_type"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end
end
 
# aliased
class Metafield < ApplicationRecord
  # the Shopify object has 'type' but 'type' is a DB reserved word
  alias_attribute :type, :variant_type
end
