From 6cbf7dc6dc37cfbd5183daba3e31fba1ccf1b9c6 Mon Sep 17 00:00:00 2001 From: Yaojia Wang Date: Tue, 4 Nov 2025 23:56:37 +0100 Subject: [PATCH] feat(backend): Implement Audit Query API (CQRS) - Sprint 2 Story 2 Task 4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented complete REST API for querying audit logs using CQRS pattern. Features: - GET /api/v1/auditlogs/{id} - Retrieve specific audit log - GET /api/v1/auditlogs/entity/{entityType}/{entityId} - Get entity history - GET /api/v1/auditlogs/recent?count=100 - Get recent logs (max 1000) Implementation: - AuditLogDto - Transfer object for query results - GetAuditLogByIdQuery + Handler - GetAuditLogsByEntity Query + Handler - GetRecentAuditLogsQuery + Handler - AuditLogsController with 3 endpoints Technical: - Multi-tenant isolation via Global Query Filters (automatic) - Read-only query endpoints (no mutations) - Swagger/OpenAPI documentation - Proper HTTP status codes (200 OK, 404 Not Found) - Cancellation token support - Primary constructor pattern (modern C# style) Tests: Build succeeded, no new test failures introduced 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .claude/settings.local.json | 9 ++- .../Controllers/AuditLogsController.cs | 81 +++++++++++++++++++ .../Queries/AuditLogs/AuditLogDto.cs | 15 ++++ .../GetAuditLogById/GetAuditLogByIdQuery.cs | 8 ++ .../GetAuditLogByIdQueryHandler.cs | 37 +++++++++ .../GetAuditLogsByEntityQuery.cs | 11 +++ .../GetAuditLogsByEntityQueryHandler.cs | 40 +++++++++ .../GetRecentAuditLogsQuery.cs | 8 ++ .../GetRecentAuditLogsQueryHandler.cs | 37 +++++++++ .../ProjectManagementModule.cs | 20 +++-- docs/plans/sprint_2_story_2_task_4.md | 45 +++++++++-- 11 files changed, 297 insertions(+), 14 deletions(-) create mode 100644 colaflow-api/src/ColaFlow.API/Controllers/AuditLogsController.cs create mode 100644 colaflow-api/src/Modules/ProjectManagement/ColaFlow.Modules.ProjectManagement.Application/Queries/AuditLogs/AuditLogDto.cs create mode 100644 colaflow-api/src/Modules/ProjectManagement/ColaFlow.Modules.ProjectManagement.Application/Queries/AuditLogs/GetAuditLogById/GetAuditLogByIdQuery.cs create mode 100644 colaflow-api/src/Modules/ProjectManagement/ColaFlow.Modules.ProjectManagement.Application/Queries/AuditLogs/GetAuditLogById/GetAuditLogByIdQueryHandler.cs create mode 100644 colaflow-api/src/Modules/ProjectManagement/ColaFlow.Modules.ProjectManagement.Application/Queries/AuditLogs/GetAuditLogsByEntity/GetAuditLogsByEntityQuery.cs create mode 100644 colaflow-api/src/Modules/ProjectManagement/ColaFlow.Modules.ProjectManagement.Application/Queries/AuditLogs/GetAuditLogsByEntity/GetAuditLogsByEntityQueryHandler.cs create mode 100644 colaflow-api/src/Modules/ProjectManagement/ColaFlow.Modules.ProjectManagement.Application/Queries/AuditLogs/GetRecentAuditLogs/GetRecentAuditLogsQuery.cs create mode 100644 colaflow-api/src/Modules/ProjectManagement/ColaFlow.Modules.ProjectManagement.Application/Queries/AuditLogs/GetRecentAuditLogs/GetRecentAuditLogsQueryHandler.cs diff --git a/.claude/settings.local.json b/.claude/settings.local.json index f560d16..1b58eff 100644 --- a/.claude/settings.local.json +++ b/.claude/settings.local.json @@ -42,7 +42,14 @@ "Bash(docker-compose up:*)", "Bash(docker-compose ps:*)", "Bash(docker-compose logs:*)", - "Bash(git reset:*)" + "Bash(git reset:*)", + "Bash(tasklist:*)", + "Bash(timeout 5 docker-compose logs:*)", + "Bash(pwsh -NoProfile -ExecutionPolicy Bypass -File \".\\scripts\\dev-start.ps1\" -Stop)", + "Bash(docker info:*)", + "Bash(docker:*)", + "Bash(docker-compose:*)", + "Bash(Start-Sleep -Seconds 30)" ], "deny": [], "ask": [] diff --git a/colaflow-api/src/ColaFlow.API/Controllers/AuditLogsController.cs b/colaflow-api/src/ColaFlow.API/Controllers/AuditLogsController.cs new file mode 100644 index 0000000..c2798c0 --- /dev/null +++ b/colaflow-api/src/ColaFlow.API/Controllers/AuditLogsController.cs @@ -0,0 +1,81 @@ +using ColaFlow.Modules.ProjectManagement.Application.Queries.AuditLogs; +using ColaFlow.Modules.ProjectManagement.Application.Queries.AuditLogs.GetAuditLogById; +using ColaFlow.Modules.ProjectManagement.Application.Queries.AuditLogs.GetAuditLogsByEntity; +using ColaFlow.Modules.ProjectManagement.Application.Queries.AuditLogs.GetRecentAuditLogs; +using MediatR; +using Microsoft.AspNetCore.Authorization; +using Microsoft.AspNetCore.Mvc; + +namespace ColaFlow.API.Controllers; + +/// +/// Audit Logs API Controller +/// Provides read-only access to audit history for entities +/// +[ApiController] +[Route("api/v1/[controller]")] +[Authorize] +public class AuditLogsController(IMediator mediator) : ControllerBase +{ + private readonly IMediator _mediator = mediator ??
