Using MYSQL enum in ecto migrations

Questions & Help Questions

I am using MYSQL instead of Postgres for my database. For Postgres it’s simple we can create a type using enum and use it in the migration to allow the values in the enum, but MYSQL doesn’t support this. Now, If I want the enum in the migrations. How can I do that with MYSQL? Let’s say this is my migration.

create table(:user) do

  add(:role, :string) # 'owner', 'worker', 'manager', 'pending_approval'
  add(:business_id, :string, null: false, default: "")
end

I only want to allow owner, worker, manager, pending approvals for role field.
Thanks.
