session in the model

Hello,

I needed a couple of session variables to allow a reader of a blog to be redirected to the correct URL if the blog name he's visiting (app/:blogname) gets updated; Question: is it convenient to pass 'base' to the model or would it be more efficient to do everything in the controller?

ex. in blog.rb

  def self.locate(base)     if !base.session[:last_visited_blog_id].nil? && base.params[:blog] == base.session[:last_visited_blog_seo]       return Blog.find_by_id(base.session[:last_visited_blog_id])     end   end

thanks!

redirection and related stuff is handled inside your controllers.
