Rails 4未经许可的参数：产品(Rails 4 Unpermitted parameters: products)

 我需要将一个数组保存到我的order.rb模型中。 
 
 数组是： params[:products] 
 
 数组给我这样的东西： 
 
[{"'name'"=>"31 DVIE33N - Traditional ", "'id'"=>"2", "'quantity'"=>"1", "'accessory'"=>{"'id'"=>"7", "'name'"=>"31-SK4BLANKD-2"}}]
 
 创建动作： 
 
def create
    @order = Order.new(order_params)

    respond_to do |format|
      if @order.save
        format.html { redirect_to admin_orders_path(@order), notice: 'Order was successfully created.' }
        format.json { render :show, status: :created, location: @order }
      else
        format.html { render :new }
        format.json { render json: @order.errors, status: :unprocessable_entity }
      end
    end
 end
 
 我的订单有限。 
 
private
    def order_params
      params.permit({:products=>[], products:[])
    end
 
 我正在尝试两种不同的方式来产品，这就是为什么你会看到上面的两个数组 
 
 请看一下，我没有使用像这样的东西： 
 
params.require(:order).permit(:products => []}, :products=>[])
 
 因为如果我使用它我得到错误： 
 
 ActionController::ParameterMissing - param is missing or the value is empty: order: 
 
 谢谢。 

I need to save an array into my order.rb model.
 
The array is: params[:products]
 
The array is giving me something like this:
 
[{"'name'"=>"31 DVIE33N - Traditional ", "'id'"=>"2", "'quantity'"=>"1", "'accessory'"=>{"'id'"=>"7", "'name'"=>"31-SK4BLANKD-2"}}]
 
Create action:
 
def create
    @order = Order.new(order_params)

    respond_to do |format|
      if @order.save
        format.html { redirect_to admin_orders_path(@order), notice: 'Order was successfully created.' }
        format.json { render :show, status: :created, location: @order }
      else
        format.html { render :new }
        format.json { render json: @order.errors, status: :unprocessable_entity }
      end
    end
 end
 
My orders params.
 
private
    def order_params
      params.permit({:products=>[], products:[])
    end
 
I'm trying two different ways to permite products, that why you will see two arrays above
 
Please take a look, I'm not using somethig like: 
 
params.require(:order).permit(:products => []}, :products=>[])
 
because if I use that I get the error:
 
ActionController::ParameterMissing - param is missing or the value is empty: order:
 
Thank you.
