Rspec test can not locate method in model file

My rspec test vote__spec.rb is stating that my up_votes method is undefined but it is listed within the votes.rb file listed below. Can anyone guide me on why its stating it is undefined?

Rspec error

2) Vote validations value validation only allows -1 or 1 as values
 Failure/Error: expect(@votes.up_votes).where(value: [1,-1])
 NoMethodError:
   undefined method `up_votes' for nil:NilClass
 # ./spec/models/vote_spec.rb:5:in `block (4 levels) in <top    (required)>'

Vote Rspec

describe Vote do
 describe "validations" do
  describe "value validation" do
    it "only allows -1 or 1 as values" do
    expect(@post.up_votes).where(value: [1,-1]) 
  end
 end
end
end

Vote.rb file

class Vote < ActiveRecord::Base
 belongs_to :user
 belongs_to :post

  def up_votes
   votes.where(value: 1).count
  end

end

Upvotes: 0

The error is appearing because the @post variable needs to be initialized. Once I initialized the @post variable as shown below, the error is resolved:

before do
  @post = Post.create(title: 'Post title', body: 'Post bodies must be   pretty long.')
  3.times {@post.votes.create(value: 1)}
  2.times {@post.votes.create(value: -1)}
end
