Design Patterns

Value: (read-only) does some math or manipulation with one input value, like a model, but for one value only
Presenter: (read-only) takes complex data, like different models, and provides extra presentation values, even HTML
Service: (mainly-write) Has a main method that writes data through delegation, and can expose the results as read-methods (eg: errors)
Query: (read-only) Joins different models and performs SQL queries on them, ideally through SQL views
Gateway: (read-write) LIB Wrap of an API (lib: favour primitives, don't depend on app)
Serializer: (read-only) Converts input to a string like JSON, CSV, PDF blob etc (prefer others)
Parser: (read-only) convert data from one format to another (prefer others)
Decorator: (read-only) extends an object with extra value otherwise written in a presenter (prefer others)

Be restful
Put view partials in proper resource (table partial, not table body)
Namespace a lot, use lib a lot, but don't put app (eg AR models) stuff in lib
Models should not use change itself in callbacks; Use services, strategies, queries, have a clear dependency hirarchy
Limit the use of validation (defaults?), they are only for UI purposes, (almost) always add relative DB constraints
DB foreign_keys, unique indexes, null with defaults
No SQL outside of the model
Write extra models (or Query objects?) to connect models
Write non-AR models
