Rails testing error: argument of WHERE must be type boolean, not type integer

Users can vote for Posts through a has_many association. I'm getting this error from running tests:

ActiveRecord::StatementInvalid: PG::DatatypeMismatch: ERROR: argument of WHERE must be type boolean, not type integer

From this test: 

test "should unvote a post the standard way" do
  @user.vote(@post_2)
  postvoterelationship = @user.active_post_vote_relationships.find_by(voted_id: @post_2.id)
  assert_difference '@user.postvoting.count', -1 do
    delete postvoterelationship_path(postvoterelationship)
  end
end

postvoterelationships_controller.rb

def destroy
  @user = Postvoterelationship.find(params[:id]).voter
  @post = Postvoterelationship.find_by(params[:id]).voted
  @user.unvote(@post)
  respond_to do |format|
    format.html do
      redirect_to @user
    end
    format.js
  end
end # destroy

routes.rb

resources :postvoterelationships,  only: [:create, :destroy]

postvoterelationship.rb

class Postvoterelationship < ActiveRecord::Base
  belongs_to :voter, class_name: "User"
  belongs_to :voted, class_name: "Post"
  validates  :voter_id, presence: true
  validates  :voted_id, presence: true
end

user.rb

has_many :postvoting, through: :active_post_vote_relationships, source: :voted

EDIT:

Have you tried to look at the SQL queries made? You can show them in test environment, check this question.

And, in postvoterelationships_controller.rb, I think:

  @post = Postvoterelationship.find_by(params[:id]).voted

should be:

  @post = Postvoterelationship.find(params[:id]).voted
