Question

I have User and Community models.

Community model will be liked by a user by this command

    if current_user.voted_up_on? @community
        current_user.dislikes @community
    else
        current_user.likes @community
    end

and I’m now trying to fetch all the users who liked @community.
I’m trying to do it with this. But it won’t return correct users.
How can I fix this?

@users =  User.where(:id => @community.likes.map(&:voter_id)).order("last_active_at DESC").limit(10)

I’m using the gem called ‘acts_as_votable’ for this

Answer 1

That would return AR::Relation

# Note: I'm not sure that polymorphic fields are: "votable_type" and "votable_id"

class Community
  ...
  def last_liked(limit = 10)
    User.includes(:votes).where(["votes.votable_type = ? AND votes.votable_id = ?", self.class.name, self.id]).order("users.last_active_at DESC").limit(limit)
  end
end
