Question

I created model objects of from generating a scaffold, but now I want to instead of linking to
/:controller/:id (/objectname/1) to /:controller/:title (/objectname/new_blog_post). How do I do this so that links will correct link to the title and not id?

I want to go from:

/:controller/:id 

to

/:controller/:name 

Answer 1

Use to param

class User < ActiveRecord::Base

  def to_param
    name.blank? ? id : name
  end

end

Or look into a plugin, acts_as_sluggable and friendly_id are ones I know of.

EDIT: Oh yes and as mentioned make sure whatever you use is unique.

EDIT:

it would work like:

class UsersController < ActionController::Base

  def index
    @users = User.all
  end

end

In view:

<% @users.each do |user| %>
  <%= link_to user.name, user_path(@user.id) %>
<% end %>

And if the that users name is John then it will render /users/John after you click that link
