Summary

  • Extends the sentinel-value filter pattern introduced in feat(transactions): add "No merchant"/"Untagged" filter options #3135 (Merchant::NO_MERCHANT_FILTER_VALUE, Tag::UNTAGGED_FILTER_VALUE) to the Category "Uncategorized" filter on the transactions page
  • Previously, Transaction::Search#apply_category_filter detected "uncategorized" by matching the translated display name against Category.all_uncategorized_names (every supported locale). This meant a real, user-created category that happened to be named "Uncategorized" (or a translation of it) could be misdetected as the synthetic filter option — no validation prevented that collision
  • Adds Category::UNCATEGORIZED_FILTER_VALUE (a stable, non-localized sentinel), a validation that rejects it as a real category name, and Category#filter_value (persisted name for real categories, sentinel for the synthetic Category.uncategorized) — mirroring Merchant#filter_value/Tag#filter_value from feat(transactions): add "No merchant"/"Untagged" filter options #3135 after all of that PR's review-fix rounds
  • _category_filter.html.erb now submits category.filter_value instead of category.name; _badge.html.erb gained a categories/UNCATEGORIZED_FILTER_VALUE special case so the filter chip still renders the localized label
  • Updated every other place that built a categories: query param for the synthetic Uncategorized category with the translated name instead of the sentinel, which would otherwise have silently broken once Search stopped matching on name: the Reports category-breakdown row link, the Dashboard outflows donut link, and the Budget category detail page's "View all transactions" link

Depends on #3135

This branches off feature/transactions-no-merchant-untagged-filter (#3135), not main, because it reuses Merchant::NO_MERCHANT_FILTER_VALUE/Tag::UNTAGGED_FILTER_VALUE as the direct pattern to mirror and its diff will include #3135's commits until that merges. Please merge #3135 first — this PR's diff against main will shrink to just the Category changes once that happens. Cross-referencing here since a missing link between related/dependent PRs was flagged as a bot review finding on a previous PR in this repo.

Not carried over from #3135 (and why)

  • The Tag-specific id subquery (PG DISTINCT/ORDER BY conflict) doesn't apply: category is a belongs_to, like merchant — max one row per transaction, so the existing left_joins(:category) stays correct as-is
  • The family-scoping fix for the Tag subquery doesn't apply either: the Category filter already operates on the already family-scoped query/family.categories
  • The token-backed-fallback-color fix (Merchant.no_merchant dropping its hardcoded DS::FilledIcon color) doesn't apply: the category filter renders categories/_badge (DS::Pill with an explicit custom_color: category.color), which has always set an explicit color for every category, uncategorized included — no bare fallback case to fix

Test plan

  • bin/rails test test/models/category_test.rb test/models/transaction/search_test.rb test/controllers/reports_controller_test.rb — 85 runs, 493 assertions, 0 failures, 0 errors (covers "Uncategorized" alone, combined with a real category, excluded when not selected, kind-filtering interaction, subcategory grouping, locale-independence now that matching is sentinel-based, and a name-collision regression test mirroring the Merchant/Tag ones)
  • bin/rubocop on changed Ruby files — no offenses
  • bin/brakeman — 0 security warnings, 0 errors
  • Manual verification on the NAS test stack: logged in, applied "Uncategorized" alone and combined with a real category on the transactions filter, confirmed the badge renders the translated label (not the raw sentinel), confirmed the Reports "Uncategorized" row link and the Budget category detail "View all transactions" link both resolve to the correct filtered transaction list using the new sentinel value

…in No merchant/Untagged filters

- Replace the top-level .distinct on the Untagged branch with an id
  subquery, since PostgreSQL rejects a DISTINCT select combined with
  reverse_chronological's CASE-expression ORDER BY unless that
  expression is also in the select list (PG::InvalidColumnReference).
- Switch both filters from matching on the localized display name to a
  stable, non-localized sentinel value (Merchant::NO_MERCHANT_FILTER_VALUE,
  Tag::UNTAGGED_FILTER_VALUE), so a real merchant/tag that happens to be
  named "No merchant"/"Untagged" (or a translation of either) can no
  longer be misdetected as the synthetic filter option. This also drops
  the per-locale I18n lookup previously needed for locale-safe detection.
- Add a badge special case so the filter chip still shows the
  translated label instead of the raw sentinel.

…ction into models

- Merchant/Tag now reject a name equal to their own sentinel value
  (NO_MERCHANT_FILTER_VALUE / UNTAGGED_FILTER_VALUE), closing the
  remaining collision where a merchant or tag literally named
  "__no_merchant__"/"__untagged__" would be misdetected as the
  synthetic filter option.
- Added Merchant#filter_value / Tag#filter_value so the
  persisted-vs-synthetic checkbox value is computed in the model
  instead of the view template, per CodeRabbit's nitpick and this
  repo's "domain logic out of views" convention.

Transaction.left_joins(:tags) queried across every family's
transactions/taggings/tags before being intersected with the
family-scoped outer query. Functionally correct (the outer query still
restricted results to the right family), but it meant every request
selecting "Untagged" ran a join across the whole platform's data
instead of just the current family's, unlike every other filter in
this file. Use family.transactions.left_joins(:tags) instead.

Merchant.no_merchant hardcoded #737373 into DS::FilledIcon instead of
letting its token-backed default (var(--color-gray-500)) apply, bypassing
theme changes.
…ant/Untagged pattern

Extends the sentinel-value filter pattern from PR we-promise#3135 (Merchant::NO_MERCHANT_FILTER_VALUE,
Tag::UNTAGGED_FILTER_VALUE) to the Category "Uncategorized" filter, which previously matched
on the translated display name across all supported locales instead of a stable, non-localized
sentinel. Adds Category::UNCATEGORIZED_FILTER_VALUE, a reserved-name validation, and
Category#filter_value, and updates every place that built a "categories:" transactions_path
link for the synthetic Uncategorized category (reports, dashboard outflows donut, budget
category detail) to use the new sentinel instead of the locale-dependent name.

📝 Walkthrough

Walkthrough

Category, merchant, and tag filters now use stable sentinel values for synthetic options. Models expose filter values, search logic handles the sentinels, and links, controls, badges, locales, assistant requests, and tests use the canonical values.

Changes

Canonical transaction filter values

Layer / File(s) Summary
Filter value contracts
app/models/category.rb, app/models/merchant.rb, app/models/tag.rb, test/models/*_test.rb
The models define reserved sentinels, synthetic-record helpers, localized names, and filter_value methods. Tests cover reserved names, locale independence, and synthetic versus persisted records.
Sentinel-aware transaction queries
app/models/transaction/search.rb, test/models/transaction/search_test.rb
Transaction search recognizes uncategorized, no-merchant, and untagged sentinels. Merchant searches include missing merchants. Untagged searches use a transaction-ID subquery. Tests cover combinations, lookalike names, locale changes, and ordering.
Filter controls and badges
app/views/transactions/searches/filters/*, config/locales/models/{merchant,tag}/en.yml
Filter controls submit canonical values and include synthetic merchant and tag options. Badges render localized names for sentinel values.
Transaction links and report data
app/controllers/{pages,reports}_controller.rb, app/views/{budget_categories,pages/dashboard,reports}/**, test/controllers/reports_controller_test.rb, test/controllers/pages_controller_test.rb
Dashboard, budget, report, Sankey, and donut links use category filter values. Report data carries those values, including opposite-direction Sankey subcategories. Controller tests verify stable values in generated links and Sankey nodes.
Client and assistant filter adapters
app/javascript/controllers/*, app/javascript/utils/transactions_filter_url.mjs, app/models/assistant/function/get_transactions.rb, test/javascript/**/*, test/models/assistant/function/get_transactions_test.rb
Client URL generation uses filterValue. The assistant maps unmatched "Uncategorized" aliases to the stable category sentinel while preserving matching real categories. Tests cover URL encoding, sentinel preservation, and assistant filtering.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 9b8cf

Assistant transaction requests may misclassify a real category when alias names are not fully reserved, potentially returning the wrong transactions. The PR is not fully merge-ready until that bounded correctness risk is addressed or explicitly accepted.

- Assistant::Function::GetTransactions still promised the literal "Uncategorized"
  string works as a category filter; translate it (and the current locale's
  display name) to Category::UNCATEGORIZED_FILTER_VALUE before building the
  search filters, so the AI assistant's documented contract keeps working now
  that Search matches on the sentinel instead of the name (chatgpt-codex-connector).
- The cashflow Sankey chart and the dashboard outflows donut's segment-click
  handler both still built their "Uncategorized" transactions deep link from the
  node/segment's localized display name. Added filter_value to the sankey node
  data and reused the donut's existing filter_value field; buildCategoryTransactionsUrl
  now takes filterValue instead of name (chatgpt-codex-connector).
- Reports subcategory rows never got a category_filter_value, so a clickable
  subcategory link built an empty categories[] filter (coderabbitai, chatgpt-codex-connector).
- Category#filter_value relied on the locale-sensitive uncategorized? predicate;
  a synthetic instance built under one locale and read under another would
  silently stop matching the sentinel. Added an explicit synthetic_uncategorized
  marker set by .uncategorized instead (coderabbitai).

Addressed all four review findings in 5429a1c:

  • Codex (P1) — non-form callers still used the localized name: Assistant::Function::GetTransactions#call now translates the documented "Uncategorized" alias (and the current locale's display name) to Category::UNCATEGORIZED_FILTER_VALUE before building the search filters. The Sankey chart's #navigateToTransactions now uses the node's filter_value (added server-side in build_cashflow_sankey_data) instead of d.name. Also proactively fixed the dashboard outflows donut's segment-click handler (donut_chart_controller.js), which had the identical bug via the same buildCategoryTransactionsUrl helper but wasn't called out explicitly.
  • Codex (P1) / CodeRabbit (duplicate) — subcategory report rows missing category_filter_value: added it to init_subcategory in ReportsController.
  • CodeRabbit — filter_value locale-dependence: Category#filter_value no longer derives from the locale-sensitive uncategorized? predicate; .uncategorized now sets an explicit synthetic_uncategorized marker instead.

Added regression tests for all four (AI-assistant alias translation, JS url-builder sentinel passthrough, and locale-independence of filter_value) plus updated buildCategoryTransactionsUrl's param name (namefilterValue) and its existing JS test file.

- Sankey opposite-direction subcategory nodes (net direction opposite their
  parent's) still built without a filter_value, so clicking one produced a
  null category filter (coderabbitai).
- Assistant::Function::GetTransactions's alias translation for "Uncategorized"
  didn't check for a real family category literally named that -- a real
  category by that name would get silently rerouted to the synthetic
  Uncategorized filter instead of its own transactions. Real categories now
  take priority over the alias (coderabbitai).
