Rails Patterns

What I Do

• Build Rails 7+ applications with Hotwire (Turbo + Stimulus)
• Design Active Record models with proper associations
• Implement background jobs with Sidekiq or Good Job
• Structure Rails applications for maintainability
• Apply Rails security best practices

When to Use Me

• Creating or extending Rails applications
• Implementing Hotwire/Turbo features
• Designing database schemas with migrations
• Setting up background job processing
• Refactoring Rails code for maintainability

Key Principles

1. Fat Model, Skinny Controller: Business logic in models/services
2. Convention Over Configuration: Follow Rails conventions
3. Strong Parameters: Always whitelist permitted params
4. N+1 Prevention: Use includes/eager_load for associations
5. Service Objects: Extract complex logic into PORO services

Common Patterns

Service Object

class UserRegistrationService
  def initialize(params)
    @params = params
  end

  def call
    User.transaction do
      @user = User.new(@params)
      @user.save!
      UserMailer.welcome(@user).deliver_later
      @user
    end
  rescue ActiveRecord::RecordInvalid => e
    errors: e.record.errors
  end
end

Turbo Frame

<%= turbo_frame_tag "messages" do %>
  <%= render @messages %>
  <%= link_to "Load more", messages_path(page: @page + 1),
      data: { turbo_frame: "messages" } %>
<% end %>

Validation

bundle exec rails db:migrate
bundle exec rails test
bundle exec rubocop
