Defined in:

Overview

Raised when a Treaty class cannot be found or resolved

## Purpose

Indicates that the system attempted to load a Treaty class (typically via constantize) but the class does not exist in the expected location.

## Usage

Raised automatically by the Controller DSL when treaty class resolution fails:

“‘ruby # In PostsController, looking for Gate::API::Posts::IndexTreaty def treaty_class

treaty_class_name.constantize

rescue NameError

raise Treaty::Exceptions::ClassName,
      I18n.t("treaty.controller.treaty_class_not_found", class_name: treaty_class_name)

end “‘

## Integration

Can be rescued by application controllers:

“‘ruby rescue_from Treaty::Exceptions::ClassName, with: :render_treaty_class_not_found_error

def render_treaty_class_not_found_error(exception)

render json: { error: exception.message }, status: :internal_server_error

end “‘

## Common Causes

  • Treaty class file not created

  • Incorrect naming convention (should match controller name pattern)

  • Typo in class name

  • Missing autoload path configuration
