<p>This plugin consists of two parts, the HTTPStatus exceptions and the default exception handler. Both of these can be changed easily to fit your own needs.</p> <h2>Changing the exception handler</h2> <p>This plugin uses <code>rescue_from</code> to catch all HTTPStatus exceptions and simply calls the <code>http_status_exception</code> method to handle it. You can reimplement this method in your application controller if you wish to customize the handling of these exceptions.</p> <p>This is the default implementation of this method:<br /> <pre><br /> def http_status_exception(exception)<br /> @exception = exception<br /> render(:template =&gt; exception.template, :status =&gt; exception.status)<br /> rescue ActionView::MissingTemplate<br /> head(exception.status)<br /> end<br /> </pre></p> <h2>Altering HTTPStatus::Base</h2> <p>All exception classes are automatically generated and based on the <code>HTTPStatus::Base</code>. You can reopen this class to change its functionality, which in turn will then be available to all exception classes. This can be done by adding a file to your <code>config/initializations</code> directory:</p> <pre> # Change the path from which the error page templates are loaded. # Default value: 'shared/http_status' HTTPStatus::Base.template_path = 'layouts/http_status' # Add a method to all exception classes class HTTPStatus::Base def hello_world 'Hello world!' end end </pre> 2008-09-21T01:38:55-07:00 58505 customization 54644 2008-09-21T01:39:28-07:00 15870
