There is no url information in the @page instance object, why I can get url path by passing this parameter into redirect_to method ?

17,603 PointsI think I found someone else who had a similar question here. I don't think I can answer the question better than Nishant did (which you can find here), however I'll try to explain briefly.
The @page instance variable is a specific record with an id. Because of this, rails is smart enough to figure out you would probably want to show that particular page (identified with the id). Thus, the show method is used as a template.
For more information you could always check out the documentation: http://api.rubyonrails.org/classes/ActionController/Redirecting.html#method-i-redirect_to

I'm assumign it just parses the id calls url_for on it and then issues a route to a controller action that matched the GET and the option(record) locally. I'm pretty sure it doesn't tell the browser to issue the show route, right?
