我正在開發一款Rails應用程序，目前正在進行測試。現在我有用戶，會話和產品。用戶和會話工作正常。但是當我運行一天前運行良好的產品測試套件時，現在我的測試中出現了stack-level too deep錯誤。Rspec失敗/錯誤：堆棧級別太深
我使用
'rspec-rails', '~> 3.3.0'
rails 4.1.8
active_model_serializers
products_controller_spec.rb
require 'rails_helper'
describe Api::V1::ProductsController, :controller => true do

end

expect(product_response[:title]).to eql @product.title
end

end

it "returns 4 unique products" do
products_response = json_response
expect(products_response[:products]).to have(4).items
end

end

end
it "renders the json response for the product updated" do

expect(product_response[:title]).to eql "An expensive TV"
end

end

end

end
end
describe "DELETE #destroy" do

@user = FactoryGirl.create :user
@product = FactoryGirl.create :product, user: @user
api_authorization_header @user.auth_token
delete :destroy, { user_id: @user.id, id: @product.id }
end
it { should respond_with 204 }
end
end
products_serializer.rb
class ProductSerializer < ActiveModel::Serializer
attributes :id, :title, :published
has_one :user
end
users_serializer.rb
class UserSerializer < ActiveModel::Serializer
embed :ids
attributes :id, :email, :created_at, :updated_at, :auth_token
has_many :products
end
這一直以來我得到這個錯誤我已經改變了唯一的文件。我可以發佈其他代碼，但我認爲它只涉及這些。任何幫助，將不勝感激。

DEPRECATION WARNING: ** Notice: embed is deprecated. **
The use of .embed method on a Serializer will be soon removed, as this should have a global scope and not a class scope.
Please use the global .setup method instead:
ActiveModel::Serializer.setup do |config|
config.embed = :ids
config.embed_in_root = false
end
