Defined in:

lib/active_harness/memory/adapter/postgresql.rb

Overview

Convenience Memory subclass for PostgreSQL-backed storage.

Requires the ‘pg’ gem installed by the application:

gem 'pg'

Usage — plain Ruby (adapter owns the connection):

mem = ActiveHarness::Memory::Postgresql.new(
  session_id: "user_42",
  url:        ENV["DATABASE_URL"],
  depth:      10
)
mem.load
# ... use ...
mem.close

Usage — Rails (borrow the AR raw connection):

mem = ActiveHarness::Memory::Postgresql.new(
  session_id: "user_42",
  connection: ActiveRecord::Base.connection.raw_connection
)
