Class Ruote::Exp::OnErrorExpression
In: lib/ruote/exp/fe_on_error.rb
Parent: FlowExpression

Up until ruote 2.3.0, ‘on_error’ was only an attribute

  sequence :on_error => 'error_handler' do
    # ...
  end

This ‘on_error’ expression makes such definitions possible

  sequence do
    on_error /unknown participant/ => 'missing_participant'
    on_error 'decommission'
    # ...
  end

where errors containing ‘unknown participant’ in their messages are handled by the participant or subprocess named ‘missing participant’, while the rest of the errors is handled by the participant or the subprocess named ‘decommission’.

Speaking of subprocesses, this is also possible

  sequence do

    on_error /unknown participant/ do
      admin :msg => 'there was an unknown participant'
    end
    on_error do
      # decommissioning...
    end

    # ...
  end
