The filter class has a class method `filter` which gets run before or after the action, depending on if it's a before or after filter. Classes used as around filters can also use the same `filter` method, which will get run in the same way. The method must `yield` to execute the action. Alternatively, it can have both a `before` and an `after` method that are run before and after the action. -The Rails API documentation has "more information and detail on using filters":http://api.rubyonrails.org/classes/ActionController/Filters/ClassMethods.html +The Rails API documentation has link:http://api.rubyonrails.org/classes/ActionController/Filters/ClassMethods.html[more information on using filters]. |
