The implementation adds a `locale` column to + `active_storage_attachments` and provides a Mobility backend that generates + per-attribute, per-locale attachment accessors on models. + + Key goals: + - One attachment per `record`/`name`/`locale` (for example `hero_image` in + `:en` and `:es`). + - Preserve the familiar Active Storage API on models (`hero_image`, + `hero_image=`, `hero_image_url`, `hero_image?`). + - Provide explicit per-locale accessors (e.g. `hero_image_en`). + - Make the writer robust so attachments are created/updated via associations + and `record_id` (UUID) is always set. + + ## Key files and where to look + + - `lib/mobility/backends/attachments/backend.rb` — Mobility backend that + dynamically generates per-locale getters, writers, predicates, associations, + and URL helpers. The writer accepts many attachable shapes (Blob, IO, + Hash, file path) and creates attachments through the `has_many` association + so `record_id` is populated. + - `lib/mobility/dsl/attachments.rb` — small DSL exposing + `translates_attached` for immediate, class-time wiring (useful in test or + engine bootstraps). Prefer `translates ... backend: :attachments` when the + backend is registered earlier in initializers. + - `db/migrate/20250829000000_add_locale_to_active_storage_attachments.rb` — + migration that adds the `locale` column, backfills, and adds a unique + index for `%i[record_type record_id name locale]`. + - Specs: + - `spec/models/translatable_attachments_writer_spec.rb` + - `spec/models/translatable_attachments_api_spec.rb` + - `spec/features/translatable_attachments_integration_spec.rb` + + ## How it works (high level) + + - For each configured attribute (e.g. `:hero_image`) the backend defines: + - `has_many :hero_image_attachments_all` — all locales (admin management). + - `has_one :hero_image_attachment` (scoped to current `Mobility.locale`). + - Per-locale accessors: `hero_image_en`, `hero_image_en=`, `hero_image_en?`, + and `hero_image_en_url`. + - Non-locale delegators: `hero_image` delegates to the accessor for the + current `Mobility.locale`. + + - Writer behavior: + - Accepts `ActiveStorage::Blob`, attached wrappers, IO-like objects, + Hashes with `:io`/`:filename`/`:content_type`, or file paths. + - If an attachment for the locale exists, the writer updates the + `blob` on the row. Otherwise it creates the attachment via the + `has_many` association so ActiveRecord sets `record_id` correctly. + - Assigning `nil` purges and destroys the localized attachment row. + + ## Model usage + + Preferred (when backend is registered in initializers): + + ```ruby + class Page < ApplicationRecord + translates :hero_image, backend: :attachments, content_type: [/^image\//], presence: true + end + ``` + + Fallback DSL (when immediate generation is required, e.g. in tests or engine + dummy apps): + + ```ruby + class Page < ApplicationRecord + extend Mobility::DSL::Attachments + translates_attached :hero_image, content_type: [/^image\//], presence: true + end + ``` + + API surface examples: + - `page.hero_image_en` — returns `ActiveStorage::Attachment` or `nil`. + - `page.hero_image` — delegates to `page.hero_image_`. + - `page.hero_image_url(host: ...)` — returns blob URL, optionally for a + variant: `page.hero_image_en_url(variant: { resize_to_limit: [300, 300] })`. + + ## Migration details and rollout + + Migration strategy used in the repo (staged, safe for rolling deploys): + 1. Add nullable `locale` string column to `active_storage_attachments`. + 2. Backfill existing rows to `I18n.default_locale` using a single SQL update. + 3. Set `locale` to NOT NULL with a default backfilled value. + 4. Add a unique index on `%i[record_type record_id name locale]` to enforce + a single attachment per locale. + + Notes: + - Use `id: :uuid` as necessary in test/dummy tables to match production. + - Back up production DB before running backfills on large tables. + + ## Testing + + - Run focused specs with the project's Docker helper: + + ```bash + bin/dc-run bundle exec rspec spec/models/translatable_attachments_writer_spec.rb + bin/dc-run bundle exec rspec spec/features/translatable_attachments_integration_spec.rb + ``` + + - The writer specs create real `ActiveStorage::Blob` objects and validate + writer behavior for different attachable inputs. Integration specs attach + a real blob and verify `rails_blob_url` behavior. + - The test helper `spec/rails_helper.rb` was updated to accept keyword options + for `create_table` so specs can use `id: :uuid`. + + ## Linting / RuboCop rationale + + The backend concentrates dynamic method generation in one file which naturally + triggers RuboCop metrics (class/method length, complexity, ABC size). To + reduce noise and keep the implementation readable we included a focused + `rubocop:disable` header with a short justification at the top of the backend + file and a matching `rubocop:enable` at the end of the file. This is + documented in the backend source and in this doc. If you'd prefer, we can + refactor the backend into smaller helpers to remove the disables. + + ## Maintenance and upgrade notes + + - If Active Storage or Mobility changes internal APIs, verify these areas: + - `attachment_reflections` usage (the backend injects a minimal reflection + shim to satisfy Active Storage callbacks). + - `ActiveStorage::Blob.create_and_upload!` semantics. + + - When updating this feature, run: + + ```bash + bin/dc-run bundle exec rspec + bin/dc-run bundle exec rubocop -A + bin/dc-run bundle exec brakeman --quiet --no-pager + ``` + + ## Docs/diagrams + + - If you add diagrams, put Mermaid sources under + `docs/diagrams/source/translatable_attachments.mmd` and export to + `docs/diagrams/exports/` using `bin/render_diagrams`. + + Diagram + ------- + + Mermaid source for the translatable-attachments ER diagram is available at: + + `docs/diagrams/source/translatable_attachments.mmd` + + You can render exports by running the project's `bin/render_diagrams` helper + which writes PNG/SVG exports into `docs/diagrams/exports/`. + + ## Example (console) + + ```ruby + page = Page.create!(title: 'Home') + page.hero_image = File.open('spec/fixtures/images/sample.png') + page.save! + page.hero_image # => attachment for current locale + I18n.with_locale(:es) { page.hero_image } # => fallback to default if no Spanish attachment + ``` + + ## Next steps / options + + - Open a PR with the code + docs changes (I can create it for you). + - Add a Mermaid diagram and wire it into the docs index. + - Refactor the backend to remove RuboCop disables (larger effort). + + --- + + If you'd like I can open a PR with these docs and the earlier code changes, or + start the refactor to remove the RuboCop disables — tell me which you prefer. diff --git a/docs/users/translatable_attachments.md b/docs/users/translatable_attachments.md new file mode 100644 index 000000000..f274b5545 --- /dev/null +++ b/docs/users/translatable_attachments.md @@ -0,0 +1,25 @@ +## What are localized images and files (for users) + +On this site, some images and files are language-specific.
