Question

标题几乎解释了这个问题。我已经将提交的JSON POST数据从开发服务器上的成功提交粘贴到测试中并且它不起作用，所以我相信问题在于我如何测试，而不是在控制器中

此外，该应用程序的测试套件已经非常成熟，因此我无法切换到RSpec。

这是失败的消息：

  1) Failure:
LessonsControllerTest#test_create [/test/controllers/lessons_controller_test.rb:24]:
"Lesson.count" didn't change by 1.
Expected: 1
  Actual: 0

这是我的测试

def setup
  @user1    = users(:michael).id
  @user2    = users(:john).id
  @date1    = Date.parse('30-8-2015')
  @date2    = Date.parse('31-8-2015')
  @school1  = schools(:hhs).id
  @school2  = schools(:harper).id
end

test "create" do
  # Invalid submission
  assert_no_difference ['Goal.count', 'Lesson.count'] do
    post :create, lesson: { date: @date1,
                            school_id: @school1,
                            user_id: @user1,
                            goals_attributes: {'0' => { text: '',
                                                        user_id: @user1 }}}
  end
  # Valid submission
  assert_difference ['Goal.count', 'Lesson.count'], 1 do
    post :create, lesson: { date: @date1,
                            school_id: @school1,
                            user_id: @user1,
                            goals_attributes: {'0' => { text: 'test',
                                                        user_id: @user1 }}}
  end

这是我的控制器，虽然我确定错误在其他地方

def create
  find_or_initialize_lesson
  if @lesson.save
    flash[:success] = "Response logged"
    redirect_to @lesson
  else
    @user = current_user
    @school_options = School.all.map { |s| [s.name, s.id] }
    render 'new'
  end
end

private

  # strong params
  def lesson_params
    params.require(:lesson).permit(:school_id, :date,
                                   goals_attributes: [:id, :user_id,
                                                      :text, :lesson_id])
  end

  # Finds a lesson with the same date and school, or creates the lesson
  def find_or_initialize_lesson
    @lesson = Lesson.find_or_initialize_by(
      date: lesson_params[:date],
      school_id: lesson_params[:school_id]
    )
    goal = Goal.new(lesson_params[:goals_attributes]['0'])
    @lesson.goals << goal
  end

lesson.rb：

class Lesson < ActiveRecord::Base
  belongs_to :school
  has_many   :users, through: :goals
  has_many   :goals, dependent: :destroy

  validates_presence_of :date, :school_id

  accepts_nested_attributes_for :goals
end

goal.rb

class Goal < ActiveRecord::Base
  belongs_to :lesson
  belongs_to :user

  validates_presence_of :text
end

schools.yml

hhs:
  name: Hillsborough High School

harper:
  name: Harper High School

users.yml里

michael:
  id: 1
  name: Michael Example
  email: test@example.com
  admin: false
  activated: true
  activated_at: <%= Time.zone.now %>
  password_digest: <%= User.digest('password') %>

john:
  id: 3
  name: John Example
  email: john@example.com
  admin: false
  activated: true
  activated_at: <%= Time.zone.now %>
  password_digest: <%= User.digest('password') %>

创建操作在实践中有效，但控制器测试不会通过
