Rails: Display user's liked post & own their posts on the same page -

i'm new rails & i've been stuck on problem hours. trying display posts user has liked , user's actual posts.

with current code, i'm getting error "undefined method `title' #" , it's being extracted line: "<%= link_to post.title, post %>".

coud shed light how can work? (more code below)

def show @user = user.find_by_username(params[:id])  if @user     @posts = @user.posts.all + @user.likes.all     render actions: :show     @likes = @user.likes.all else     render file: 'public/404', status: 404, formats: [:html] end end 

here's routes file:

resources :likes, only: [:create, :destroy] resources :posts  devise_scope :user   'register', to: 'devise/registrations#new'   'edit', to: 'devise/registrations#edit'   'login', to: 'devise/sessions#new'   'logout', to: 'devise/sessions#destroy' end 

here's 'show' view:

<% if @posts %>   <% @posts.each |post| %>     <%= link_to post.title, post %>   <% end %> <% end %> 

"<%= link_to post.title, post %> display <%= post.inspect %>" here's results

<post id: 11, title: "testing123", user_id: 2, created_at: "2013-05-18 19:25:45", updated_at: "2013-05-18 19:25:45"> #<like id: 23, post_id: 10, user_id: 2, created_at: "2013-05-18 21:39:17", updated_at: "2013-05-18 21:39:17"> 

it works when use -> @posts = @user.posts.all problem starts when use -> @posts = @user.posts.all + @user.likes.all

which gives me "undefined method `title'" message..

you may want add user model...

class user < activerecord::base    has_many :likes   has_many :liked_posts, :through => :likes, :source => :post    ...  end 

then, in controller can this

@posts = @user.posts + @user.liked_posts
