Defined in:

lib/treaty/entity/attribute/validation/base.rb

Overview

Base class for request and response validation.

Purpose

Provides common interface for validation used in Treaty. Subclasses implement specific validation logic for requests and responses.

Responsibilities

1. Validation Interface - Defines common validation interface
2. Factory Pattern - Provides class-level validate! method

Subclasses

• Request::Validation - Validates request data (uses Orchestrator::Request)
• Response::Validation - Validates response data (uses Orchestrator::Response)

Usage

Subclasses must implement:

• validate! - Performs validation and returns transformed data

Example usage:

Request::Validation.validate!(version_factory: factory, data: params)

Factory Method

The self.validate!(...) class method provides a convenient factory pattern:

Request::Validation.validate!(version_factory: factory, data: params)
# Equivalent to:
Request::Validation.new(version_factory: factory).validate!(data: params)

Architecture

Works with:

• VersionFactory - Provides version information
• Orchestrator::Base - Performs actual validation and transformation

Class Method Summary

• .validate! ⇒ Hash

  Class-level factory method for validation Creates instance and calls validate!.

Instance Method Summary

• #initialize(version_factory:) ⇒ Base constructor

  Creates a new validation instance.

• #validate! ⇒ Hash

  Performs validation and transformation Must be implemented in subclasses.

Constructor Details

#initialize(version_factory:) ⇒ Base

Creates a new validation instance

Parameters:

• version_factory (VersionFactory) —

  Factory containing version information

# File 'lib/treaty/entity/attribute/validation/base.rb', line 59

def initialize(version_factory:)
  @version_factory = version_factory
end

Class Method Details

.validate! ⇒ Hash

Class-level factory method for validation Creates instance and calls validate!

Parameters:

• args (Hash) —

  Arguments passed to initialize and validate!

Returns:

• (Hash) —

  Validated and transformed data

# File 'lib/treaty/entity/attribute/validation/base.rb', line 52

def self.validate!(...)
  new(...).validate!
end

Instance Method Details

#validate! ⇒ Hash

Performs validation and transformation Must be implemented in subclasses

Returns:

• (Hash) —

  Validated and transformed data

Raises:

• (Treaty::Exceptions::NotImplemented) —

  If subclass doesn't implement

# File 'lib/treaty/entity/attribute/validation/base.rb', line 68
