Rails + Hotwire Prompt Architecture

Generate prompts that produce modern Rails 7 code with Turbo Drive, Turbo Frames, Stimulus controllers, and proper Active Record patterns.

❌ Generic AI Output

# Generic prompt — outdated Rails
class PostsController < ApplicationController
  def index
    @posts = Post.all  # N+1 query
    respond_to do |format|
      format.html
      format.json { render json: @posts }
    end
  end

  def create
    @post = Post.new(params[:post])  # No strong params!
    @post.save
    redirect_to posts_path
  end
end

✅ Prompt Architect Output

# Prompt Architect — modern Rails 7 + Hotwire
class PostsController < ApplicationController
  before_action :authenticate_user!

  def index
    @posts = Post.includes(:author, :comments)
                 .order(created_at: :desc)
                 .page(params[:page])
  end

  def create
    @post = Current.user.posts.build(post_params)
    if @post.save
      respond_to do |format|
        format.turbo_stream
        format.html { redirect_to @post, notice: "Published!" }
      end
    else
      render :new, status: :unprocessable_entity
    end
  end

  private
  def post_params
    params.require(:post).permit(:title, :body, :category_id)
  end
end

Automated Quality Enforcement

Every prompt includes strict bans and deprecation rules tailored to your Ruby on Rails + Hotwire + Turbo + Stimulus stack

strict-bans.md — AI Prompt Architect

# ⛔ STRICT BANS — Enforced Constraints

## Framework Version Enforcement
- **BANNED**: React class components → Use functional components + hooks
- **BANNED**: `componentWillMount`, `componentWillUpdate` → Use `useEffect`
- **BANNED**: `getInitialState` → Use `useState` or `useReducer`
- **BANNED**: `createClass` syntax → Use arrow function components
- **BANNED**: PropTypes runtime validation → Use TypeScript interfaces
- **BANNED**: `defaultProps` static → Use ES6 default parameters

## TypeScript Enforcement
- **BANNED**: `any` type annotations → Use `unknown` + type guards
- **BANNED**: `@ts-ignore` comments → Fix the actual type error
- **BANNED**: Non-null assertions (`!`) → Use optional chaining (?.)
- **BANNED**: `enum` keyword → Use `as const` union types
- **BANNED**: `namespace` declarations → Use ES modules

## Security Constraints
- **BANNED**: `eval()`, `Function()` constructors
- **BANNED**: `innerHTML` assignments → Use `textContent` or sanitise
- **BANNED**: Hardcoded secrets, API keys, or credentials
- **BANNED**: `http://` URLs in production → Enforce `https://`
- **BANNED**: `*` CORS origins in production → Whitelist domains
- **BANNED**: SQL string concatenation → Use parameterised queries
- **BANNED**: `localStorage` for auth tokens → Use httpOnly cookies

## State Management
- **BANNED**: Prop drilling beyond 2 levels → Use Context or Zustand
- **BANNED**: `useEffect` for data fetching → Use React Query / SWR
- **BANNED**: Mutable state mutations → Use immutable update patterns
- **BANNED**: Global mutable variables → Use React state or stores

## API & Data Patterns
- **BANNED**: `fetch` without error handling → Wrap in try/catch
- **BANNED**: Untyped API responses → Define response interfaces
- **BANNED**: `console.log` in production → Use structured logger
- **BANNED**: Synchronous file I/O → Use async/await patterns
- **BANNED**: Unbounded `.find()` / `.filter()` on large arrays → Use Map/Set

## CSS & Styling
- **BANNED**: Inline styles for layout → Use CSS modules or Tailwind
- **BANNED**: `!important` overrides → Fix specificity properly
- **BANNED**: Fixed pixel breakpoints → Use relative units (rem/em)
- **BANNED**: `z-index` values > 100 → Use a z-index scale system

❌ The Problem

AI models often produce Rails 5 patterns, ignore Hotwire conventions, and generate N+1 queries with raw SQL.

✅ The Solution

Prompt Architect constrains output to Rails 7+, Hotwire Turbo Streams, and modern Active Record includes/eager loading.

Frequently Asked Questions

Does it support Turbo Streams?

Yes — including turbo_stream.append, .prepend, .replace responses, and broadcast patterns with Action Cable.

Can it generate Stimulus controllers?

Prompts include Stimulus controller patterns with targets, values, and outlet connections.

Does it handle Active Record associations?

Yes — has_many :through, polymorphic, delegated types, and counter caches are supported.

Technical Deep Dive

How do I set up the initial project architecture with these technologies?

Use AI Prompt Architect to generate a scaffold prompt that includes directory structure, configuration files, environment setup, and dependency installation commands tailored to your exact stack combination. The prompt enforces best-practice file organisation from the start.
