Question

我正在使用Rails 4和Ruby 2，我正在尝试修复一个在创建新记录时给我一个Forbidden Attributes错误的错误。

这是我的控制器中的创建代码：

def create
    @instructor = Instructor.new(instructor_params)

    respond_to do |format|
      if @instructor.save
        format.html { redirect_to @instructor, notice: 'Instructor was successfully created.' }
        format.json { render json: @instructor, status: :created, location: @instructor }
      else
        format.html { render action: "new" }
        format.json { render json: @instructor.errors, status: :unprocessable_entity }
      end
    end
  end

我强大的参数代码：

  def instructor_params
    params.require(:instructor).permit(:bio, :hometown, :name, :school, :sort_order, :started_sailing, :started_teaching, :photo)
  end

这是我的instructor.rb文件：

class Instructor < ActiveRecord::Base
  validates_presence_of :bio, :name

  mount_uploader :photo, PhotoUploader

  def experience
     distance_of_time_in_words_to_now (self.started_sailing)
  end
end

我得到的错误是：

ActiveModel::ForbiddenAttributesError in InstructorsController#create
ActiveModel::ForbiddenAttributesError

 @content_type="image/jpeg",
 @headers="Content-Disposition: form-data; name=\"instructor[photo]\"; filename=\"Libby2.jpg\"\r\nContent-Type: image/jpeg\r\n">},
 "commit"=>"Create Instructor"}

我正在使用cancan进行授权，并找到了此页面： https://github.com/ryanb/cancan/issues/835

我尝试了下面显示的AntonTrapp发布的解决方法，但这也没有用。

before_filter do
  resource = controller_name.singularize.to_sym
  method = "#{resource}_params"
  params[resource] &&= send(method) if respond_to?(method, true)
end

知道我做错了什么吗？我很难过。

提前致谢。
