Srijith, the second isn't correct because you're
trying to find a page that doesn't exist the database.
Thus, this will generate ActiveRecord::RecordNotFound
as would the first line if it doesn't exist and the second
should like like the following:
@page = @course.pages.build( params[:page] )
@David - make sure that you have a 'new' method
on the PagesController defined as follows:
def new
@course = Course.find( params[:course_id] )
@page = @course.pages.build
end
Good luck,
