Ruby on Rails未经许可的参数有很多通过

我有订单和产品，以及一个名为orders_products的连接表，订单有许多产品通过order_products并接受嵌套归因于它。Ruby on Rails未经许可的参数有很多通过

当我试图挽救它口口声声说不允许，paramters：order_product

PARAMS

def order_params 
    params.require(:order).permit(:id, :order_number, :customer_id, {order_products_attributes: [:id, :order, :product, :quantity ]}, {:product_ids => []}) 

end

订货型号

class Order < ActiveRecord::Base 
    belongs_to :customer 
    has_many :order_products, class_name: "OrderProduct" 
    has_many :products, through: :order_products 
    accepts_nested_attributes_for :order_products, :allow_destroy => true 
end

订购产品型号

class OrderProduct < ActiveRecord::Base 
    belongs_to :product 
    belongs_to :order 
end

订单控制器新的动作

def new 
    @order = Order.new 
    @order.order_products.build 
end

订购单

<%= simple_form_for @order do |f| %> 
<%= f.input :order_number %> 

<%= f.fields_for :order_product do |fa| %> 
    <%= fa.input :product, collection: Product.all %> 
    <%= fa.input :quantity %> 

    <% end %> 

<%= f.association :customer, as: :select %> 

<%= f.submit %> 
<% end %>

PARAMS散列 - { “UTF8”=> “√”， “authenticity_token”=> “yBrH91u0OHTSPnCFO/484Ff6CRtyRLSg5AKD1Lc33k4 =”，“order”=> {“order_number”=>“0121”，“order_product”=> {“product”=>“4”， “量”=> “5”}， “CUSTOMER_ID”=> “3”}， “提交”=> “创建订单”}

好吧我现在加了这个，我得到了不允许的参数：产品 – user2829533

你的参数现在是什么样子？ –

也许'产品'需要是一个关联？ '<％= fa.association：product，如：：select，collection：Product.all％>'。 –
