Question

我正在使用设计和导轨4.我有以下型号：

class Video
  include Mongoid::Document
  include Mongoid::Timestamps

  field :url,                type: String
  field :video_id,           type: String
  field :title,              type: String
  field :description,        type: String
  field :suggested_by_name,  type: String
  field :suggested_by_email, type: String
  field :active,             type: Boolean, default: false

end

使用以下控制器：

class Frontend::VideosController < ApplicationController

  before_action :authenticate_user!, only: [:index, :edit, :update, :destroy]

  def index
  end

  def new
    @videos = Video.new
  end

  def create
    if @person = Video.create(params[:video])
      flash.now[:success] = "Thanks for suggest this video"
      redirect_to root_path
    else
      flash.now[:error] = "Impossible to add this suggestion"
      redirect_to new_frontend_video_path
    end
  end

  def edit
  end

  def update
  end

  def destroy
  end

  private
    def video_params
      params.require(:video).permit(:url, :title, :description, :suggested_by_name, :suggested_by_email)
    end

end

我正试图在我的mongodb上保存一条记录，但我得到了：

::加载ActiveModel ForbiddenAttributesError

所以我认为我在强参数中犯了一个错误，请帮忙。

在create操作更改params[:video]至video_params：

 def create
    if @person = Video.create(video_params)
      flash.now[:success] = "Thanks for suggest this video"
      redirect_to root_path
    else
      flash.now[:error] = "Impossible to add this suggestion"
      redirect_to new_frontend_video_path
    end
  end

您应该permit参数，而不是Rails加注ActiveModel::ForbiddenAttributesError。

new使用rails 4 - ActiveModel :: ForbiddenAttributesError
