How do I create relationships and associations for a User Model of Devise

I am using devise for my user model and in the routes.rb I have devise_for :users How would I go about giving users posts?

Would it just be in the routes:

resources :users do
    resources :posts
end

Or do you have to do something special due to devise

Those routes will work, additionally you need to set up your relationships in your models, assuming your posts table includes user_id as a foreign key:

class User < ActiveRecord::Base
  has_many :posts
  has_many :comments
end

class Post < ActiveRecord::Base
  belongs_to :user
  has_many :comments
end

class Comments < ActiveRecord::Base
  belongs_to :user
  belongs_to :post
end

edit

To add the foreign key to your Post model:

rails g migration add_user_id_to_posts user_id:integer

This will create a migration file in the db/migrate folder that looks like:

class AddUserIdToPosts < ActiveRecord::Migration
  def self.up
    add_column :posts, :user_id, :integer
  end

  def self.down
    remove_column :posts, :user_id
  end
end

You can then migrate these changes to your database using: rake db:migrate
