While trying to install Passenger on my staging server the following error occurred:After digging around a little bit I figured out something that would work:passenger-4.0.0.rc4.gem is the file that was produced at the time of this writing.

Default values and attributes are set in config/routes.rb.Each time the values are built for a sitemap url or meta tag for a page, the default values are used as a base. The controller in question is "asked" to provide values for defined attributes and those values are merged with the default values overwriting them. Also, if a model object is available the same process is repeated.DuckMap defines default attributes for all values required by sitemap...

DuckMap supports the following HTML Meta Tags.To include the meta tags in your app, simply add the view helper method: sitemap_meta_tag.The default behavior is to acquire values from the first model found on a controller. The model is interrogated for the following attributes: :canonical, :description, :keywords, :lastmod, and :title. If the attribute exists on the model, then, the value is used. You have the option of mapping attributes to your model.For example, here we are...

Filters give you the power to control the contents of a sitemap based on verbs, controller name, action name, and route name. The default configuration is to exclude everything except routes that have an action name of :index or :show. For most Rails apps, that should cover the general needs of generating a sitemap.You can apply route filters using two methods: - Using exclude and include statements within a sitemap block. - Using exclude and...

I think the easiest way to explain sitemaps with nested resources is to explain the process from a high level.When a sitemap is built:Given the following configuration:Would have a named route like:The mechanism used to acquire these values is: sitemap_capture_segments. You can see that the "show" action for the route has segment keys :book_id and :id. When the url is built, the Comment model is "asked" for the segment key values for the route by...

DuckMap provides support for namespaces and could be a big help for logically grouping sitemaps for large sites. Sitemaps behave in the same manner with or without a namespace. The main difference is the actual path pointing to the sitemap.A few points:Given the following config/routes.rbNotice that we were able to insert a sitemap without using a block and the default name is still sitemap.The demo application shows a few combinations of what is possible....
