无法引用参数

-1

class Checkout::PaymentsController < ApplicationController 
    before_action :params 
    def create 

     if Order.where(:date => params[:date]).present? 
      redirect_to reserva_path 
     end 
    end 

     def params 
     params.require(:Order).permit(:date) 
     end 
    end 

class Products::ReservesController < ApplicationController 
    before_action :set_product, only: [:show] 

    def index 
    @products = Product.all 
    end 

    def show 
    @product = Product.find(params[:pr_id]) 
    end 

    def set_product 
    @partner = Product.find(params[:pr_id]) 
    end

端

和视图（show.html.erb）

<div class="detail"> 
    <h3><%= @product.name %></h3> 
    <p><%= @product.description %></p> 
    <h4>R$ <%= @product.price %></h4> 
    <h4>Escolha a data</h4> 
    <%= form_tag(checkout_payments_path) do%> 
     <%= hidden_field_tag :product_id, @product.id %> 
     <div class="data"> 
     <%= date_select(:date, :date, start_year: 2017) %> 
     </div> 
     <%= submit_tag "Alugar", class: "btn btn-success"%> 
    <% end %>

show.html.erb将product_id和date_select的日期作为参数发送给Checkout/Payment控制器，但是我收到错误，说不能引用控制器（返回是动作控制器参数的一个实例）我做错了什么？

OBS：控制器在不同的命名空间

编辑：服务器日志错误

编辑2：只见日期作为哈希过去了，看到日志

我加入控制器：

def date_params 
    params.require(:date).permit(:date) 
end

，但我仍然有这个vallue：

#<ActionController::Parameters:0x0000000d4d7c60>

什么是确切的错误信息？请在服务器日志 – Pavan

中生成的'params'发布看看编辑，请 –

我认为这个问题是你坚强的参数使用

# I delete before_action here 

def create 
    @order = Order.new(params) 
    # here is you filter your order through params method below 
end 

def params 
    params.require(:Order).permit(:date) 
end

为您的代码上面有具体日期，检查顺序（从PARAMS值）

my_date = params[:date].to_date 
if Order.where("date = ? ",my_date).count > 0 
    redirect_to reserva_path 
end

不工作，这里是日志（循环） app/controllers/checkout/payments_controller.rb：10：在'params' app/controllers/checkout/payments_controller.rb：10：在'params' –
