Overview

Request-scoped metadata storage for events.

EventMetainformation provides thread-isolated attribute storage for contextual data that should be attached to events, such as the acting user, controller action, or application version. It extends ActiveSupport::CurrentAttributes for automatic request isolation and includes ActiveModel::Validations for optional validation rules.

## Configuration

Attributes are defined via the array configuration, and validations via a block DSL:

Funes.configure do |config|
  config.event_metainformation_attributes = [:user_id, :action, :git_version]

  config.event_metainformation_validations do
    validates :user_id, presence: true
    validates :action, format: { with: /\A\w+#\w+\z/ }
  end
end

## Supported Validators

All standard ActiveModel validators are supported:

  • presence

  • format (with regex)

  • length (minimum, maximum, is, in)

  • numericality

  • inclusion / exclusion

  • custom validators

## Usage

Set values in a controller concern:

Funes::EventMetainformation.user_id = current_user.id
Funes::EventMetainformation.action = "#{controller_name}##{action_name}"

Check validity (when validations are configured):

Funes::EventMetainformation.valid?
Funes::EventMetainformation.errors.full_messages
