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.
