| description | Handle Hotwire form workflows: form submission lifecycle, inline editing, validation errors, typeahead/autocomplete, modal forms, and external form controls. Prefer this skill when the core problem is correctness and UX of form interaction. Use hwc-navigation-content for pagination/tabs/filter navigation, hwc-realtime-streaming for WebSocket/Turbo Stream broadcasting, hwc-media-content for image/video/audio behavior, hwc-ux-feedback for generic loading/transition polish, and hwc-stimulus-fundamentals for framework-level Stimulus APIs not tied to forms. |
Forms & Validation
Implement form-centric Hotwire workflows with Turbo Frames and Stimulus.
Core Workflow
- Identify the form flow: create/edit, inline edit, typeahead, modal form, or external controls.
- Wrap the form interaction scope in a Turbo Frame when validation errors must rerender in place.
- Return
422 for validation failures and 303 for successful redirects.
- Handle post-submit behavior with
turbo:submit-end only when Turbo defaults are insufficient.
- Preserve user context during rerenders (focus/caret/selection).
Guardrails
- Keep one source of truth for input state; avoid duplicate controls across frame and non-frame DOM.
- Use the HTML
form attribute for controls rendered outside the target <form> hierarchy.
- Avoid firing submit logic on every keystroke without debounce/throttle.
- Keep post-submit behavior explicit when form responses update only a frame.
