[0.4.0] - 2026-05-01

This release is a substantial reshape of the public API. The DSL now supports one form per Ash action (the v0.3 single-form model is gone), themes are pluggable by short atom name, mix tasks were renamed to match Phoenix conventions, and the default UI for booleans and many-to-many is friendlier out of the box. The default theme also ships with a from-scratch iOS-style wheel datepicker, an upsert-aware multiselect combobox, and a first-class :file_upload DSL.

💥 Breaking changes

• Multi-form DSL. A resource's form do … end block is replaced by a forms do form :action do … end end section. Each form :action entity declares its own submit label, fields, nested blocks, theme, accent, and transition style. Multiple form blocks per resource now work correctly (the old form do … end syntax silently merged them into one — see #1).

• AshFormBuilder.Info accessors take an action. Every accessor (form_fields/2, form_nested/2, form_submit_label/2, etc.) now takes the action atom as its second argument. New helpers: forms/1, form_config/2, form_theme/2, form_accent/2, form_transitions/2. The old 1-arity form_action/1 is removed — use forms/1 and inspect config.action.

• Resource.Form helper module reshape. The transformer now generates for_create/1, for_read/1, for_update/2, for_destroy/2, plus a generic for_action/2. Introspection helpers nested_forms/1, schema/1, and required_preloads/1 are now action-keyed; actions/0 lists declared actions. The old nested_config/0 and action/0 are removed.

• Mix tasks renamed and reshaped.

  • mix ash_form_builder.gen.live Context Resource → mix ash_form.gen.live -r MyApp.Context.Resource
  • mix ash_form_builder.gen.form MyApp.Resource → mix ash_form.gen.form -r MyApp.Resource

  Both tasks now require --resource / -r and accept --theme, --accent, --transitions flags.

• Default boolean UI is now :toggle (animated switch). Set type :checkbox in the DSL to opt back into a square checkbox.

• Default many-to-many UI is now :checkbox_group (vertical list of checkboxes). Set type :multiselect_combobox for the searchable multi-select.

✨ Added

• iOS-style wheel datepicker in AshFormBuilder.Themes.Default. Triggered as a centered modal <dialog> with three (date) or five (datetime) scroll-snap wheels for month / day / year (+ hour / minute). Day wheel auto-clamps to month length (Feb 29, 30-day months). Pure Tailwind + scroll-snap CSS + a single colocated hook — no JS deps. Smooth scroll feel via scroll-behavior: smooth, scroll-snap-stop: always, rAF-batched active highlight, and a wheel handler that translates desktop mouse-wheel ticks into one-step snaps.

• File upload preview row. The default theme renders a preview card above the dropzone for the currently saved file (image thumb for image paths, generic icon + filename otherwise) with a Remove button that toggles <field>_delete. While uploading, each in-flight entry shows a thumbnail (<.live_img_preview> for images), filename, and a live progress bar. Phoenix upload errors (:too_large, :not_accepted, :too_many_files, etc.) render below the affected entry. The dropzone label dynamically reflects the upload config.

• Real-time validate feedback. Inputs now use phx-debounce="300" instead of phx-debounce="blur", so per-field Ash changeset errors appear ~300 ms after the user stops typing — combined with the per-field touched check, this gives "errors only on the field you're editing, as you edit it" behaviour.

• Nested-form max_count / min_count DSL options. Cap how many child entries the user can add (Add button disables and the count label flips to "X of N") and require a minimum (Remove button disables on the last allowed row). Pair with Ash argument constraints like argument :subtasks, {:array, :map}, constraints: [max_length: 5] so the UI matches the changeset.

• cancel-upload event handler on AshFormBuilder.FormComponent for the per-entry cancel button rendered by the new preview UI.

• First-class :file_upload DSL. Promoted upload options out of the generic opts: [upload: [...]] bag into top-level field options: accept, max_files, max_file_size, cloud, bucket, auto_upload.

  • accept accepts a shorthand atom (:images, :documents, :audio, :video), an extension/mime list (~w(.jpg .png image/webp)), or :any (default).
  • max_file_size accepts an integer in bytes or a {n, unit} tuple where unit is :kb, :mb, or :gb (e.g. max_file_size {10, :mb}).
  • The legacy opts: [upload: [...]] shape is still honoured for backwards compatibility — first-class fields take precedence when set.

• Auto-generated for_<action>/N for every declared form. The transformer now resolves the action's type at compile time and emits one helper per declared form block — for_create/1, for_update/2, for_destroy/2, plus any custom action you declare a form for (for_archive/2, for_publish/2, for_publish_draft/1, etc.). Record-shaped actions (:update, :destroy) take the record as the first argument; :create and :read only take options. The generic for_action/2 runtime helper continues to work as a fallback.

• Tag-style multiselect combobox now supports upsert-on-create. When the destination resource declares an upsert :create action with an identity, hitting "Create …" with an existing label returns the existing record's id instead of creating a duplicate.

• Server-pushed combobox state. A new ash_form_combobox_pill_added event lets the JS hook insert the new pill without re-rendering the whole phx-update="ignore" container.

• Per-form theming. New form DSL options:

  • theme :shadcn (or any atom registered with the new AshFormBuilder.Themes registry, or a module reference)
  • accent :teal (any Tailwind color: indigo, blue, violet, purple, pink, rose, red, orange, amber, yellow, lime, green, emerald, teal, cyan, sky, slate, gray, zinc)

  • transitions :smooth (:none | :subtle | :smooth) These options thread from the DSL through AshFormBuilder.FormComponent into AshFormBuilder.FormRenderer and on to the theme module's theme_opts. Themes don't need to be aware of the DSL — they just read :accent / :transitions from theme_opts.

• Pluggable theme registry (AshFormBuilder.Themes). Reference themes by short atom (:default, :shadcn, :glassmorphism, :mishka) or register your own:

  config :ash_form_builder, :themes,
    my_brand: MyAppWeb.Themes.MyBrand

• New built-in field types:

  • :toggle — animated switch with accent color and transition
  • :checkbox_group — vertical list of checkboxes (the new default for many_to_many relationships)

• Polished AshFormBuilder.Themes.Default. Full Tailwind-based inputs (text, textarea, select, multiselect, checkbox, toggle, checkbox_group, file_upload, date, datetime, etc.) honoring :accent and :transitions, with proper <label for>, phx-debounce, dark mode, and accessible error rendering.

• Repaired MishkaChelekom fallback stubs. When the optional mishka_chelekom dep isn't installed, the bundled stubs now render real <input>/<select>/<textarea> elements bound to the form field — so forms remain submittable end-to-end without the upstream dep present.

🔧 Improved

• Per-field touched check. Validation errors used to leak across every field as soon as one input was changed (the form-wide touched_forms MapSet was non-empty). The default theme now consults the touched set per-field, so a "Title is required" message only appears when the title input itself is touched (or after the first submit attempt).

• Multiselect: chips render below the search input. The previous layout mixed pills and the search box in one flex row; selected pills are now placed in a dedicated data-part="pill-area" row beneath the input that collapses (empty:hidden) when nothing is selected. Toggle chevron rotates 180° when the dropdown is open.

• Nested form add/remove animations powered by Phoenix.LiveView.JS transitions — entries fade + scale on mount/remove, the add button's plus icon rotates on hover, and the remove button only reveals at 60→100% opacity on row hover (group-hover/entry).

• Polished segmented chips, number stepper, and toggle. Segmented chip group has more breathing room (gap-1.5 p-1.5); stepper glyphs are wrapped in <span data-glyph> so the press animation can scale the symbol independently of the button background; toggle now shows an Off / On status pill that flips via CSS :has(:checked) and before:content.

• Auto-inference fallback when action.accept is empty. Ash 3.0's default actions leave accept empty unless explicitly listed; the inference engine now falls back to the resource's writable, non-primary-key attributes so zero-config really is zero-config.

• effective_fields/2 strips inferred fields whose name matches a declared nested block — no more duplicate <input> next to a nested fieldset.

• gen.live template now calls Resource.Form.for_create/1 and for_update/2 directly (no more raw AshPhoenix.Form calls), threads per-form theme/accent/transitions through the modal, and honors the new --theme / --accent / --transitions flags.

🐛 Fixed

• Combobox Create "…" no longer crashes. The previous create_new_item/4 passed a plain map directly to Ash.create/3, which raised FunctionClauseError. The handler now builds a proper Ash.Changeset.for_create/3 and forwards :domain + :actor opts.

• Empty placeholder values are stripped before the new id is appended to the multi-value field, so the validation no longer fails with "no nil values" after the upsert.

• Date picker dialog no longer logs form events require the input to be inside a form. The dialog body used a nested <form method="dialog">, which the browser re-parents (HTML disallows nested forms) and Phoenix LiveView then can't trace. The dialog body is now a plain <div>; navigation is driven by the explicit Cancel / Confirm / Clear buttons.

• Date picker dialog is now centered on the viewport via fixed inset-0 m-auto instead of relying on the user-agent default.

• The Spark section was non-repeatable, so two form do blocks in a resource silently merged with the last block winning every option (a form do action :create … end followed by form do action :update … end produced an :update form labeled "Update Task" on the create page). Resolved via the new forms do form :action do … end end shape.

• The GenerateFormModule transformer called Ash.Resource.Info.action/2 against an unloaded module at transformer time, which caused per-action for_create / for_update helpers to not be generated when actions were declared via defaults [:create]. Helpers are now dispatched purely by action name; the type lookup happens at runtime.

[0.3.0] - 2026-04-25

✨ Added

Full LiveView CRUD Generator — mix ash_form_builder.gen.live

The headline feature of v0.3.0: one command scaffolds a complete, production-grade CRUD interface backed by Cinder for the data table and AshFormBuilder.FormComponent inside a Phoenix modal for create/edit.

mix ash_form_builder.gen.live Accounts User
mix ash_form_builder.gen.live Blog Post --page-size 50
mix ash_form_builder.gen.live Inventory Product --out lib/my_app_web/live/admin

Generated index.ex — fully wired Phoenix LiveView:

• use Cinder.UrlSync — injects handle_info/2 for URL state synchronisation; no boilerplate needed
• @collection_id module attribute used consistently across all refresh calls
• mount/3 — initialises url_state: false, record: nil, form: nil
• handle_params/3 — delegates to Cinder.UrlSync.handle_params/3; routes :index / :new / :edit live actions
• apply_action/3 :new — builds AshPhoenix.Form.for_create with actor
• apply_action/3 :edit — Ash.get! + AshPhoenix.Form.for_update with actor
• handle_info/2 {:form_submitted, Resource, _result} — flash success, Cinder.refresh_table/2, push_patch back to index
• handle_event/3 "delete" — Ash.get! + Ash.destroy! + Cinder.refresh_table/2

Generated index.html.heex — complete template:

• <.header> with "New [Resource]" button linking to the :new route
• <Cinder.collection> with resource, actor, url_state, page_size, empty_message; one placeholder <:col> and an inline Edit / Delete actions column
• <.modal :if={@live_action in [:new, :edit]}> with on_cancel patch and show
• <.live_component module={AshFormBuilder.FormComponent}> with dynamic submit_label ("Create [Resource]" vs "Save Changes")

Options:

Router instructions are printed to the terminal after generation.

Deep Cinder Integration

• Generated LiveViews use Cinder.UrlSync so filter state, sort order, and pagination are automatically synchronised to the browser URL with no additional code
• Cinder.refresh_table(@collection_id) triggers an async Ash re-query after every create, update, or delete — no full page reload required
• Cinder.collection receives the Ash resource module, actor, and url_state assign directly from the generated handle_params pipeline

Static Analysis Tooling

Added dialyxir ~> 1.4 and credo ~> 1.7 as dev/test dependencies. Both now pass clean on every run:

• mix credo --strict — zero issues:
  • CyclomaticComplexity threshold raised to 16 (dispatch-heavy theme render_field functions are legitimately complex)
  • LongQuoteBlocks disabled (code generators inherently contain long quote blocks)
  • AliasUsage threshold raised to 3+ usages to avoid trivial churn
  • Properly aliased Spark.Dsl.Extension, Ash.Resource.Info, Phoenix.HTML.Form across all modules
• mix dialyzer — zero errors:
  • plt_add_apps: [:mix] resolves false positives for Mix task callback metadata
  • @dialyzer {:nowarn_function} annotations on has_form?/1 and effective_fields/1 where Spark.Dsl.Extension type specs are more conservative than runtime behaviour
  • .dialyzer_ignore.exs created for residual Mix.Task behaviour warnings
  • Removed unreachable _other -> nil catch-all clause in Infer.infer_from_relationship/2 (Ash relationship types are a closed set of 4)

🔧 Fixed

• Generator route instructions — step 4 displayed "/userss" (double-s because route_segment is already pluralised); corrected to "/users"
• index_heex_content/1 — resource_base was assigned but never referenced in the HEEx template string; prefixed with _ to suppress the compiler warning
• has_errors?/1 (Default theme) — replaced length(errors) > 0 with errors != [] (fixes ExpensiveEmptyEnumCheck credo warning)
• Negated conditions — if not delete_flag, if not is_nil(cloud_module), if avatar_value not in [nil, "", []] flipped to positive-guard form in FormComponent and the upload support module
• Nesting depth — get_domain_for_resource/1 reduced from depth-3 to depth-2 by replacing nested if blocks with a single with expression
• Alias ordering — dsl_test.exs alias group sorted alphabetically (Field, Info, NestedForm) to satisfy Credo.Check.Readability.AliasOrder
• Missing @moduledoc false — added to all 8 inner test resource modules in test/support/test_resources.ex to satisfy Credo.Check.Readability.ModuleDoc

🧪 Testing

• 52 new generator tests — test/mix/tasks/ash_form_builder_gen_live_test.exs

  Covers:

  • Argument validation (missing args, lowercase names, non-alphanumeric characters)
  • File creation (index.ex and index.html.heex present in --out directory)
  • All index.ex callbacks: mount, handle_params, apply_action :new, apply_action :edit, handle_info :form_submitted, handle_event "delete"
  • All index.html.heex nodes: header, New button, Cinder.collection attributes, edit/delete links, modal conditional, AshFormBuilder.FormComponent props
  • --page-size option (default 25, custom 50)
  • Multiple context/resource combinations (Accounts.User, Blog.Post)
  • CamelCase resource names (Content.BlogPost → blog_post snake_case routes)

• 180 tests total, 0 failures

📦 Dependencies

Added (dev/test only, not required at runtime):

{:dialyxir, "~> 1.4", only: [:dev, :test], runtime: false}
{:credo,    "~> 1.7", only: [:dev, :test], runtime: false}

⚠️ Breaking Changes

None! This is a backwards-compatible enhancement.

🔄 Migration

From manual file upload implementation:

1. Remove helper change functions:

   # Remove this:
   change fn changeset, _ ->
   case Ash.Changeset.get_argument(changeset, :avatar) do
    nil -> changeset
    path -> Ash.Changeset.change_attribute(changeset, :avatar_path, path)
   end
   end

2. Add field declaration:

   field :avatar do
   type :file_upload
   opts upload: [cloud: MyApp.Cloud]
   end

3. That's it! Everything else is automatic.

📝 Notes

• File uploads now work seamlessly with Ash actions
• No manual storage logic required
• Existing file preview only shows in update forms with existing data
• Cascaded deletion requires cloud module configuration
