Question

I am using the thumbsup gem to allow users to vote on microposts and now I am trying to render all of the users that have voted for a select micropost. All of the voting functionality and routes work fine, however I am now getting the error from my Micropost controller:

undefined method `voted_for?'

micropost controller:

def into_it  #for the view; displays who likes the post
  @micropost = Micropost.find(params[:id])
  @users = User.voted_for?(@micropost)
  render 'show_users_into_it'
end

micropost model:

acts_as_voteable

User model:

acts_as_voter

Schema info:

# Table name: users
#  id                       
#  name            
#  email    

# Table name: microposts
#  id         :integer       
#  comment    :text
#  user_id    :integer    

# Table name: votes
#  id            :integer          not null, primary key
#  vote          :boolean          default(FALSE), not null
#  voteable_id   :integer          not null
#  voteable_type :string(255)      not null
#  voter_id      :integer
#  voter_type    :string(255)

Do I have to do some sort of SQL query instead is there no simple way? thanks.

Answer 1

You are getting an undefined method voted_for? because you are calling it on the User class instead of an instance of the user.

I think the method you’re looking for is voters_who_voted which would be used like:

def into_it  #for the view; displays who likes the post
  @micropost = Micropost.find(params[:id])
  @users = @micropost.voters_who_voted
  render 'show_users_into_it'
end
