I start to use Socialization gem. So, created User model with devise:
class User < ActiveRecord::Base
    has_many :posts
    devise :database_authenticatable, 
    :registerable,
    :recoverable, 
    :rememberable, 
    :trackable, 
    :validatable
    acts_as_follower
    acts_as_followable
    acts_as_liker
end
Then I created Post with scaffold:
class Post < ActiveRecord::Base
   belongs_to :user
   acts_as_likeable
end
And I want to allow user like posts. But I don't know how to create view with like button, also I dont know how to write methods for likes. Please give me little example. I'm new in rails
I create link in veiw/posts/show.html.erb. 
<%= link_to "Like", like_post_path(@post), 
:method => :post, :class => 'btn btn-primary btn-xs' %>
And method in app_contoller:
def like        
    @post = Post.find(params[:id])
    current_user.like!(@post)       
end
How to write route for this?
                        
You can already test in your console to see how it works first:
rails cSo you can create an action:
likesin your Posts controller.And create a route for that action:
And in your views:
