SEO rubyonrails

In your model override the to_param method. For instance

class Post < ActiveRecord::Base
   def to_param
           “#{id}-#{title.parameterize}.html”
   end
end

Assume we have a post :

 @post = Post.create! :title => "simple SEO with rubyonrails",
                                  :content => "blah blah ... "

In our view we call

link_to  "Detail", post_url(@post) # "1-simple-SEO-with-rubyonrails"

We get seo url pretty easy.

In our controller we simply call the find or where method as normal since Rails will convert the params[:id] to integer automatically :

@post = Post.where(["id=?", params[:id]) # or @post = Post.find(params[:id])
