我正在尝试为 RyanBates 编写 CanCan 的权限规范，但出现错误 "uninitialized constant Ability::CanCan"

Question

我认为这个问题 CanCan uninitialized constant Ability::CanCan 没有解决我的问题。

根据 CanCan 的说法 Abilities 并不难测试。我跟着 https://github.com/ryanb/cancan/wiki/Testing-Abilities 写规格：

当我尝试以下命令时

bundle exec rspec spec/cancan/ability.rb

我收到以下错误

/projects/ATS/app/models/ability.rb:2:in `<class:Ability>': uninitialized constant Ability::CanCan (NameError)
        from /home/shiva/projects/ATS/app/models/ability.rb:1:in `<top (required)>'
        from /home/shiva/projects/ATS/spec/cancan/ability.rb:3:in `<top (required)>'
from /home/shiva/.rvm/gems/ruby-2.1.1/gems/cancan-1.6.10/lib/cancan.rb:1:in `<top (required)>'
        from /home/shiva/projects/ATS/spec/rails_helper.rb:14:in `<top (required)>'
        from /home/shiva/projects/ATS/spec/cancan/ability.rb:1:in `<top (required)>'

我的代码在spec/cancan/ability.rb

require 'rails_helper'

RSpec.describe Ability, type: :model do
  subject(:ability) {Ability.new(user)}
  let(:user) {nil}
  context 'Logged in as CSA' do
    let(:org) {create(:organization)}
    let(:user) {create(:user, organization: org, role_ids: [Role::ROLE_CSA])}
    describe 'Not Permitted' do
      it 'to visit /admins' do
          it {is_expected.to be_able_to(:manage, Workflow.new)}
      end

    end
  end
end

和代码片段 models/ability.rb

class Ability
  include CanCan::Ability

  def initialize(user, url, admin_session_id, my_applicant_id)
    if user.present?
      user.roles[0].permissions_by_organization(user).each do |permission|
        case permission.subject_class

Answer 1

我得到了问题的答案。

问题是 spec 文件的 filename 应该是
spec/cancan/ability_spec.rb 但它是
spec/cancan/ability.rb

我应该调用
bundle exec rspec spec/cancan/ability_spec.rb
