i am having the page about.html under app/views/pages/

please give some suggestions of why i am getting like this .

Answer 1

Your code is looking for what is called a named route. You need to define these in config/routes.rb. In addition you will need some controller and action to handle them. See this post describing a very simple way to handle static pages by way of illustration.

To get the about_path named route, then you would add this to routes.rb

map.about "/pages/about", :controller => "pages", :action => "show", :id => "about"

Then add your about page contents to a file called app/views/pages/about.html.erb

Finally:

$ rake routes

tells you all of the named routes defined for your application and what they do
