  def run
    "some report"
  end

Run the given method before run is called on an Operation.

Examples:

before_run :validate_inputs, if: :should_validate? before_run :validate_inputs, unless: :skip_validation?

private def validate_inputs validate_required data end

Run the given block before run is called on an Operation.

This runs before run is invoked on the operation. You can set defaults, validate, or perform any other setup necessary before running the operation.

Optionally you can pass an if or unless argument which allows you to run this conditionally. The symbol should reference a method you've defined that returns a truthy/falsey value.

before_run(unless: :skip_callback?) do
  validate_required data
end

private def skip_callback?
  false
end
