Multiple MySQL Versions for Development

Options included below:

• Using Docker docker-compose
• Using Homebrew brew

Using Docker (recommended)

This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

This was my solution for a polymorphic many-to-many association

class ItemCountry < ActiveRecord::Base
  belongs_to :locatable, :polymorphic => true
  belongs_to :country
  # fields are :locatable_id, :locatable_type, :country_id
end

class Title < ActiveRecord::Base

has_many :countries, :through => :item_countries, :as => :locatable
