EctoTrail allows to store changeset changes into a separate audit_log table.
Installation and usage

def deps do
[{:ecto_trail, "~> 0.4.0"}]
end- Ensure
ecto_trailis started before your application:
def application do
[extra_applications: [:ecto_trail]]
end- Add a migration that creates
audit_logtable topriv/repo/migrationsfolder:
defmodule EctoTrail.TestRepo.Migrations.CreateAuditLogTable do
@moduledoc false
use Ecto.Migration
def change do
create table(:audit_log, primary_key: false) do
add :id, :uuid, primary_key: true
add :actor_id, :string, null: false
add :resource, :string, null: false
add :resource_id, :string, null: false
add :changeset, :map, null: false
timestamps([type: :utc_datetime, updated_at: false])
end
end
end- Use
EctoTrailin your repo:
defmodule MyApp.Repo do
use Ecto.Repo, otp_app: :my_app
use EctoTrail
end- Configure table name which is used to store audit log (in
config.ex):
config :ecto_trail, table_name: "audit_log"- Use logging functions instead of defaults. See
