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 on using filters":http://ap.rubyonrails.org/classes/ActionController/Filters/ClassMethods.html. - h3. Verification Verifications make sure certain criteria are met in order for a controller or action to run. They can specify that a certain key (or several keys in the form of an array) is present in the +params+, +session+ or +flash+ hashes or that a certain HTTP method was used or that the request was made using +XMLHttpRequest+ (Ajax). The default action taken when these criteria are not met is to render a 400 Bad Request response, but you can customize this by specifying a redirect URL or rendering something else and you can also add flash messages and HTTP headers to the response. It is described in the "API documentation":http://ap.rubyonrails.org/classes/ActionController/Verification/ClassMethods.html as "essentially a special kind of before_filter". -- cgit v1.2.3
