Vanilla Rails
Default architecture when writing Rails, from the Vanilla Rails philosophy of 37signals/Basecamp. Apply it while implementing — do not wait for a review command or for the user to name the philosophy.
Based on Fizzy
This skill is informed by Fizzy - a production Rails application from 37signals.
Key Fizzy patterns:
- Controllers call Active Record directly:
@board.update!(board_params),@card.comments.create!(comment_params) - Models composed of concerns:
include Closeable, Golden, Postponable, Watchable - State tracked with dedicated models:
has_one :closure,has_one :goldness - No
app/services/directory - Complex multi-step processes use plain objects or ActiveRecord models with state
Quick Start
Vanilla Rails embraces Rails's built-in patterns and avoids premature abstraction:
Core Philosophy: Thin controllers that directly invoke a rich domain model. No service layers or other artifacts unless genuinely justified.
┌─────────────────────────────────────────┐
│ CONTROLLERS │
│ (Thin - HTTP concerns only) │
└─────────────────────────────────────────┘
↓
┌─────────────────────────────────────────┐
│ MODELS │
│ (Rich - Business logic lives here) │
└─────────────────────────────────────────┘
↓
┌─────────────────────────────────────────┐
│ ACTIVE RECORD / DATABASE │
└─────────────────────────────────────────┘
Core Rule: Don't add layers beyond what Rails provides unless you have a clear, justified reason.
Default constraint
This skill is the house style for Rails work, not an optional review lens. When loaded during implementation, apply the principles below while writing code. Do not ask which review command to run.
Do:
- Put domain logic on the model, or a namespaced concern of that model
- Keep controllers to params + one model call
- Prefer a new nested resource over a custom controller action
- Keep jobs and mailers shallow:
_laterenqueues,_nowdoes the work on the model
Do not introduce app/services/, app/queries/, interactors, managers, or handlers unless the bar in When Services Are Actually OK is met — and say so in the change.
Skip this overlay for migrations, gem/dependency bumps, CSS/JS, view-only markup, credentials, and anything that is not Rails application code.
Explicit commands
Use these only when the user asks to review, analyze, or plan a simplification — not as the default response to Rails implementation:
- Review code changes -
/vanilla-rails:review - Analyze codebase -
/vanilla-rails:analyze - Plan simplification -
/vanilla-rails:simplify [goal]
Core Principles
The Three Rules
- Thin Controllers - Controllers only parse params and invoke model methods
- Rich Domain Model - Business logic belongs in models
- No Premature Abstraction - Don't create service layers by default
Common Anti-Patterns
| Anti-Pattern | Example | Fix |
|---|---|---|
| Fat service | 100-line service with domain logic | Move logic to model |
| Anemic model | Model with only attributes and associations | Add business methods |
| Controller as orchestrator | Controller calling multiple services | Call rich model methods |
| Premature service | Simple CRUD wrapped in service | Use plain Active Record |
| Service explosion | DoSomethingService for every action | Most should be model methods |
See Anti-Patterns Reference for complete list.
When Services Are Actually OK
Services are justified when:
- Coordinating multiple models (orchestration, not domain logic)
- External API interactions
- Multi-step workflows with transaction boundaries
- Operations that don't naturally belong to any single model
Fizzy uses plain objects for this:
# Multi-step signup with ActiveModel::Model
class Signup
include ActiveModel::Model
validates :email_address, format: { with: URI::MailTo::EMAIL_REGEXP }
validates :full_name, presence: true
def create_identity
@identity = Identity.find_or_create_by!(email_address: email_address)
@identity.send_magic_link(for: :sign_up)
end
def complete
# Complex account creation with rollback handling
end
end
Fizzy uses ActiveRecord models for stateful operations:
# Stateful import with status tracking
class Account::Import < ApplicationRecord
enum :status, %w[ pending processing completed failed ].index_by(&:itself), default: :pending
def process(start: nil, callback: nil)
processing!
# Import logic with ZIP file handling
mark_completed
rescue => e
mark_as_failed
raise e
end
end
Style Preferences
Conditional Returns
Prefer expanded conditionals over guard clauses (unless returning early at method start for non-trivial bodies).
# Bad - Guard clause
def todos_for_new_group
ids = params.require(:todolist)[:todo_ids]
return [] unless ids
@bucket.recordings.todos.find(ids.split(","))
end
# Good - Expanded conditional
def todos_for_new_group
if ids = params.require(:todolist)[:todo_ids]
@bucket.recordings.todos.find(ids.split(","))
else
[]
end
end
Method Ordering
classmethodspublicmethods (withinitializeat top)privatemethods
Order methods vertically by invocation order to help readers follow code flow.
CRUD Controllers
Model endpoints as REST operations. Don't add custom actions - introduce new resources instead.
# Bad
resources :cards do
post :close
post :reopen
end
# Good
resources :cards do
resource :closure
end
Visibility Modifiers
No newline under visibility modifiers; indent content under them.
class SomeClass
def some_method
# ...
end
private
def some_private_method
# ...
end
end
If a module only has private methods, mark private at top with extra newline but don't indent.
Async Operations
Write shallow job classes that delegate to domain models:
- Use
_latersuffix for methods that enqueue jobs - Use
_nowsuffix for synchronous methods
# Fizzy pattern: _later enqueues, _now does the work
module Event::Relaying
extend ActiveSupport::Concern
included do
after_create_commit :relay_later
end
def relay_later
Event::RelayJob.perform_later(self)
end
def relay_now
# actual implementation
end
end
class Event::RelayJob < ApplicationJob
def perform(event)
event.relay_now
end
end
Bang Methods
Only use ! for methods with a counterpart without !. Don't use ! to flag destructive actions.
Pattern Catalog
| Pattern | Use When | Reference |
|---|---|---|
| Plain Active Record | Simple CRUD, no coordination needed | plain-activerecord.md |
| Rich Model API | Complex behavior single model should own | rich-models.md |
| Concern | Shared behavior across models, or organizing one rich model | concerns.md |
| Delegated Type | "Is-a" relationships with shared identity | delegated-type.md |
| Service/Form | Only when genuinely justified | when-to-use-services.md |
Red Flags (Over-Engineering)
Run /vanilla-rails:analyze to detect:
- 🔴 Service objects for simple operations
- 🔴 Business logic in services instead of models
- 🔴 Controllers with more than 10 lines
- 🔴 "Managers", "Handlers", "Processors" that are just proxies
- ⚠️ Anemic models (attributes + associations only)
- ⚠️ Domain logic scattered across service objects
- ⚠️ Unnecessary abstraction layers
Examples
See examples/ directory for before/after comparisons showing the Vanilla Rails approach.
Philosophy
"Vanilla Rails is plenty." - DHH
Most applications don't need layers beyond what Rails provides. Embrace:
ActiveRecordmodels as the home of business logic- Controllers as thin wrappers around model calls
- Callbacks and concerns for code organization
- Jobs and mailers called from models when appropriate
Resist:
- Service layers as default architecture
- Premature extraction
- "Clean Architecture" for simple CRUD
- Pattern-driven development
For more depth, read the Vanilla Rails blog post.

# Vanilla Rails
Default architecture when writing Rails, from the Vanilla Rails philosophy of 37signals/Basecamp. Apply it while implementing — do not wait for a review command or for the user to name the philosophy.

- Models composed of concerns: `include Closeable, Golden, Postponable, Watchable`
