Instance Method Details

#cutoff(seconds, options = {}) ⇒ Object

Set a cutoff for the controller

Can be called multiple times with different options to configure cutoffs for various conditions. If multiple conditions match a given controller, the last applied cutoff "wins".

Examples:

class ApplicationController
  # Apply a global maximum
  cutoff 30
end

class UsersController < ApplicationController
  # Override the base time limit
  cutoff 5.0
  cutoff 3.0, only: :show
  cutoff 7, if: :signed_in
end

Parameters:

  • seconds (Float, Integer) —

    The allowed seconds for a controller action

  • options (Hash) (defaults to: {}) —

    Options to pass to around_action. For example, pass :only, :except, :if, to limit the scope of the cutoff.
