From c52f313e2dc5b78981473586bb460679b9549ad3 Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Sun, 21 Dec 2025 13:31:59 -0600 Subject: [PATCH] 1. User Authentication - Full auth system with email/password (using phx.gen.auth) - Login, registration, password reset - Session management with remember-me functionality - Magic link login support 2. Organization Management - Multi-tenant organization system - Organizations schema with unique slugs - Automatic organization creation when users register - Organization switcher UI at /orgs 3. Membership System - Users can belong to multiple organizations - 4 permission levels: Owner, Admin, Member, Viewer - Complete permission matrix implemented - Join/leave organizations 4. Invitation System - Email-based invitations with secure tokens - 7-day expiration on invites - Track who invited and who accepted 5. Authorization - Full policy system (Organizations.Policy) - can?(membership, :action, :resource) helper - Enforced via plugs in router 6. LiveView Pages - /orgs - List all your organizations - /orgs/new - Create new organization - /orgs/:slug - Organization dashboard (placeholder) 7. Database Schema - users table - organizations table - organization_memberships table - organization_invitations table - All migrations run successfully --- AGENTS.md | 31 ++ IMPLEMENTATION_PLAN.md | 403 ++++++++++++++++++ config/config.exs | 13 + config/test.exs | 3 + lib/towerops/accounts.ex | 330 ++++++++++++++ lib/towerops/accounts/scope.ex | 33 ++ lib/towerops/accounts/user.ex | 137 ++++++ lib/towerops/accounts/user_notifier.ex | 85 ++++ lib/towerops/accounts/user_token.ex | 161 +++++++ lib/towerops/organizations.ex | 228 ++++++++++ lib/towerops/organizations/invitation.ex | 48 +++ lib/towerops/organizations/membership.ex | 29 ++ lib/towerops/organizations/organization.ex | 50 +++ lib/towerops/organizations/policy.ex | 46 ++ .../components/layouts/root.html.heex | 20 + .../user_registration_controller.ex | 32 ++ .../controllers/user_registration_html.ex | 5 + .../user_registration_html/new.html.heex | 31 ++ .../controllers/user_session_controller.ex | 88 ++++ .../controllers/user_session_html.ex | 9 + .../user_session_html/confirm.html.heex | 59 +++ .../user_session_html/new.html.heex | 70 +++ .../controllers/user_settings_controller.ex | 77 ++++ .../controllers/user_settings_html.ex | 5 + .../user_settings_html/edit.html.heex | 40 ++ lib/towerops_web/live/dashboard_live.ex | 11 + .../live/dashboard_live.html.heex | 45 ++ lib/towerops_web/live/org_live/index.ex | 22 + .../live/org_live/index.html.heex | 39 ++ lib/towerops_web/live/org_live/new.ex | 43 ++ lib/towerops_web/live/org_live/new.html.heex | 17 + lib/towerops_web/router.ex | 44 ++ lib/towerops_web/user_auth.ex | 255 +++++++++++ mix.exs | 1 + mix.lock | 2 + ...0251221192340_create_users_auth_tables.exs | 32 ++ .../20251221192454_create_organizations.exs | 15 + ...192505_create_organization_memberships.exs | 21 + ...192513_create_organization_invitations.exs | 26 ++ test/support/conn_case.ex | 41 ++ test/support/fixtures/accounts_fixtures.ex | 89 ++++ test/towerops/accounts_test.exs | 398 +++++++++++++++++ .../user_registration_controller_test.exs | 50 +++ .../user_session_controller_test.exs | 221 ++++++++++ .../user_settings_controller_test.exs | 149 +++++++ test/towerops_web/user_auth_test.exs | 293 +++++++++++++ 46 files changed, 3847 insertions(+) create mode 100644 IMPLEMENTATION_PLAN.md create mode 100644 lib/towerops/accounts.ex create mode 100644 lib/towerops/accounts/scope.ex create mode 100644 lib/towerops/accounts/user.ex create mode 100644 lib/towerops/accounts/user_notifier.ex create mode 100644 lib/towerops/accounts/user_token.ex create mode 100644 lib/towerops/organizations.ex create mode 100644 lib/towerops/organizations/invitation.ex create mode 100644 lib/towerops/organizations/membership.ex create mode 100644 lib/towerops/organizations/organization.ex create mode 100644 lib/towerops/organizations/policy.ex create mode 100644 lib/towerops_web/controllers/user_registration_controller.ex create mode 100644 lib/towerops_web/controllers/user_registration_html.ex create mode 100644 lib/towerops_web/controllers/user_registration_html/new.html.heex create mode 100644 lib/towerops_web/controllers/user_session_controller.ex create mode 100644 lib/towerops_web/controllers/user_session_html.ex create mode 100644 lib/towerops_web/controllers/user_session_html/confirm.html.heex create mode 100644 lib/towerops_web/controllers/user_session_html/new.html.heex create mode 100644 lib/towerops_web/controllers/user_settings_controller.ex create mode 100644 lib/towerops_web/controllers/user_settings_html.ex create mode 100644 lib/towerops_web/controllers/user_settings_html/edit.html.heex create mode 100644 lib/towerops_web/live/dashboard_live.ex create mode 100644 lib/towerops_web/live/dashboard_live.html.heex create mode 100644 lib/towerops_web/live/org_live/index.ex create mode 100644 lib/towerops_web/live/org_live/index.html.heex create mode 100644 lib/towerops_web/live/org_live/new.ex create mode 100644 lib/towerops_web/live/org_live/new.html.heex create mode 100644 lib/towerops_web/user_auth.ex create mode 100644 priv/repo/migrations/20251221192340_create_users_auth_tables.exs create mode 100644 priv/repo/migrations/20251221192454_create_organizations.exs create mode 100644 priv/repo/migrations/20251221192505_create_organization_memberships.exs create mode 100644 priv/repo/migrations/20251221192513_create_organization_invitations.exs create mode 100644 test/support/fixtures/accounts_fixtures.ex create mode 100644 test/towerops/accounts_test.exs create mode 100644 test/towerops_web/controllers/user_registration_controller_test.exs create mode 100644 test/towerops_web/controllers/user_session_controller_test.exs create mode 100644 test/towerops_web/controllers/user_settings_controller_test.exs create mode 100644 test/towerops_web/user_auth_test.exs diff --git a/AGENTS.md b/AGENTS.md index 0e1fe7ac..1913b13e 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -44,6 +44,37 @@ custom classes must fully style the input -
