From cc517fd85c265814bba3cd602d59d6b512af27f9 Mon Sep 17 00:00:00 2001 From: Boromir Date: Fri, 15 May 2026 10:05:52 -0700 Subject: [PATCH 1/6] feat(339): add Category entity, CRUD handlers, safe delete, BlogPost category assignment Closes #339 (backend scope) Domain: - Add Category entity (Name unique enforced, Description required) - Add ICategoryRepository interface with name-uniqueness helpers - Add ExistsByCategoryAsync to IBlogPostRepository for safe-delete guard - Add CategoryId (Guid?) to BlogPost with AssignCategory / RemoveCategory methods Web/Data: - Add BlogDbContext.Categories DbSet with unique index on Name - Add MongoDbCategoryRepository (EF Core + Mongo) - Add CategoryDto / CategoryMappings - Update BlogPostDto + BlogPostMappings to include CategoryId - Update MongoDbBlogPostRepository with ExistsByCategoryAsync Web/Features/Categories: - GetCategoriesQuery + GetCategoriesHandler (list) - GetCategoryByIdQuery + GetCategoryByIdHandler (single lookup) - CreateCategoryCommand + Validator + Handler (uniqueness check via Conflict result) - EditCategoryCommand + Validator + Handler (not-found + uniqueness check) - DeleteCategoryCommand + Validator + Handler (blocks delete when posts assigned) Web/Features/BlogPosts: - CreateBlogPostCommand: add optional CategoryId param - CreateBlogPostHandler: call AssignCategory when CategoryId provided - EditBlogPostCommand: add optional CategoryId param - EditBlogPostHandler: call AssignCategory when CategoryId provided Program.cs: - Register MongoDbCategoryRepository / ICategoryRepository AppHost seed data: - Seed General category (stable Guid 00000000-...-0001) - Assign all seeded blog posts to General category Tests: - Update BlogPostDto constructors in test fixtures to pass null
