Rails: list of pins that a user upvoted - ruby-on-rails

Question

I have a rails app with a basic set up to allows users to upvote pins, those pins are ordered from the most upvoted to the less upvoted. What I would like to do now is to render the lists of pins that a user upvoted on his profile.
Here is my config:
app/controllers/pins_controllers.rb
def upvote
#pin = Pin.find(params[:id])
if #pin.votes.create(user_id: current_user.id)
flash[:notice] = "Thank you for upvoting! You can upvote a startup only once."
redirect_to(pins_path)
else
flash[:notice] = "You have already upvoted this!"
redirect_to(pins_path)
end
end
app/models/pin.rb
class Pin < ActiveRecord::Base
belongs_to :user
has_many :votes, dependent: :destroy
has_many :upvoted_users, through: :votes, source: :user
has_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>" }
has_attached_file :logo, :styles => { :medium => "300x300>", :thumb => "100x100>" }
end
app/models/user.rb
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :pins
has_many :votes, dependent: :destroy
has_many :upvoted_pins, through: :votes, source: :pin
end
app/models/vote.rb
class Vote < ActiveRecord::Base
belongs_to :user
belongs_to :pin, counter_cache: true
validates_uniqueness_of :pin_id, scope: :user_id
end
And my routes.rb
resources :pins do
member do
post 'upvote'
end
end
Do you have any ideas how I could do that?

Answer 1

You can get the pins a user #user upvoted for example by the following:
#pins_for_user = []
#user.votes.each do |vote|
#pins_for_user << vote.pin
end
You can embedd this in your user controller, for example in the show method.
Then you can refer to #pins_for_user in your show view (show.html.erb) and display it by:
<% #pins_for_user.each do |pin| %>
<%= pin.name %> # or any other code to display that special pin
<% end %>
