Pundit::NotDefinedError：从 Pundit 0.3 迁移到 1.0 时无法找到策略

Question

当我在我的一个项目规范类上运行 rspec wit pundit 1.0 版 时，我遇到了多个以前从未见过的错误。但是，当我切换到以前版本的 pundit (0.3) 时，一切正常。

到目前为止，我注意到的是新版本的 pundit @error 在 create 函数中没有正确分配（而不是错误类，我从错误类中得到一个错误消息字符串）。

class ErrorsController < ApplicationController
  before_action :set_execution_environment

  def authorize!
    authorize(@error || @errors)
  end
  private :authorize!

  def create
    @error = Error.new(error_params)
    authorize!
  end

  def error_params
    params[:error].permit(:message, :submission_id).merge(execution_environment_id: @execution_environment.id)
  end
  private :error_params

在规格/工厂中：

FactoryGirl.define do
  factory :error, class: Error do
    association :execution_environment, factory: :ruby
    message "exercise.rb:4:in `<main>': undefined local variable or method `foo' for main:Object (NameError)"
  end
end

在规范/控制器/error_controller.rb 中：

 describe 'POST #create' do
    context 'with a valid error' do
      let(:request) { proc { post :create, execution_environment_id: FactoryGirl.build(:error).execution_environment.id, error: FactoryGirl.attributes_for(:error), format: :json } }

      context 'when a hint can be matched' do
        let(:hint) { FactoryGirl.build(:ruby_syntax_error).message }

        before(:each) do
          expect_any_instance_of(Whistleblower).to receive(:generate_hint).and_return(hint)
          request.call
        end

        expect_assigns(execution_environment: :execution_environment)

        it 'does not create the error' do
          allow_any_instance_of(Whistleblower).to receive(:generate_hint).and_return(hint)
          expect { request.call }.not_to change(Error, :count)
        end

        it 'returns the hint' do
          expect(response.body).to eq({hint: hint}.to_json)
        end

        expect_json
        expect_status(200)
      end

      context 'when no hint can be matched' do
        before(:each) do
          expect_any_instance_of(Whistleblower).to receive(:generate_hint).and_return(nil)
          request.call
        end

        expect_assigns(execution_environment: :execution_environment)

        it 'creates the error' do
          allow_any_instance_of(Whistleblower).to receive(:generate_hint)
          expect { request.call }.to change(Error, :count).by(1)
        end

        expect_json
        expect_status(201)
      end
    end

我收到错误消息

Pundit::NotDefinedError: 无法为 #<Pundit::Error: {"message"=>"exercise.rb:4:in' 找到策略 Pundit::ErrorPolicy：未定义 局部变量或方法foo' for main:Object (NameError)", "execution_environment_id"=>1}>

因为没有正确创建错误类。之后，错误类中的每个测试都失败了。

我的政策：

class AdminOrAuthorPolicy < ApplicationPolicy
  [:create?, :index?, :new?].each do |action|
    define_method(action) { @user.internal_user? }
  end

  [:destroy?, :edit?, :show?, :update?].each do |action|
    define_method(action) { admin? || author? }
  end
end


class ErrorPolicy < AdminOrAuthorPolicy
  def author?
    @user == @record.execution_environment.author
  end
end

我对任何其他课程都没有这样的问题。

过去半小时我一直在处理同样的问题，尽管使用的是 minitest，解决方案是运行 spring stop 然后重新运行我的测试。希望这会有所帮助。
