Rails 5 uuid issue with sqlite

I'm converting my rails 5.1 app to start using UUID instead of incremental ids as the default active_record.

I've changed my migration files to use id: :uuid

class CreateProjects < ActiveRecord::Migration[5.1]
  def change
    create_table :projects, id: :uuid do |t|
      t.string :title
      t.text :description

      t.timestamps
    end
  end
end

I've added a migration file to support 'uuid-ossp' and 'pgcrypto' as I intend to use pg in prod.

class EnablePgcryptoExtension < ActiveRecord::Migration[5.1]
  def change
    enable_extension 'uuid-ossp'
    enable_extension 'pgcrypto'
  end
end

But when I try to create an object, I get an error as if the id was null.

ActiveRecord::NotNullViolation: SQLite3::ConstraintException: NOT NULL constraint failed: projects.id: INSERT INTO "projects" ("created_at", "updated_at") VALUES (?, ?)

the schema.rb offers a hint that 'uuid' is not a known type

# Could not dump table "projects" because of following StandardError
#   Unknown type 'uuid' for column 'id'

I suggest I could start using string types instead of uuid for sqlite3, but I intend on using postgres for production and would like to use uuids.

Should I use pg in dev or is there another way ?
