Question

这里是rails的新手，

我理解错误，但我不知道为什么我的测试没有通过。我也不知道如何查看传递给动作的params哈希，所以调试对我来说有点混乱。

测试失败错误

1) SectionsController PATCH #update with valid attributes finds the correct course.section assigns @section
     Failure/Error: patch :update, course_id: @section.course_id, id: @section.id
     ActionController::ParameterMissing:
       param is missing or the value is empty: section
     # ./app/controllers/sections_controller.rb:52:in `section_params'
     # ./app/controllers/sections_controller.rb:36:in `update'
     # ./spec/controllers/sections_controller_spec.rb:95:in `block (4 levels) in <top (required)>'

测试

describe "PATCH #update" do
    context "with valid attributes" do
      before :each do 
          @course = create(:course)
          @section = create(:section, name: "section1")
      end
      it "finds the correct course.section & assigns @section" do 
        patch :update, course_id: @section.course_id, id: @section.id
        expect(assigns(:section)).to eq(@section)
      end
    end
end

部分控制器更新方法

def update
    @course = Course.find(params[:course_id])
    @section = Section.find(params[:id])
      if @section.update_attributes(section_params)
      flash[:success] = "the section has been updated"
      redirect_to [@course, @section]
    else
      flash[:error] = "you must enter the correct information"
      render action: "edit"
    end
  end

private 

  def section_params
    params.require(:section).permit(:name, :course_id) 
  end
end

路线

resources :courses do
    resources :sections
end

模型

class Section < ActiveRecord::Base
    belongs_to :course
    validates :name, :course_id, presence: true
end

class Course < ActiveRecord::Base
    has_many :sections
    accepts_nested_attributes_for :sections
    validates :name, presence: true
end

感谢您的帮助！

使用所有必需参数进行发布的正确方法如下：

post :update, course_id: @section.course_id, id: @section.id, section: {name: @section.name,course_id: @section.course_id}

Rails 4 Params缺失，Rspec测试嵌套资源控制器更新方法
