查看/表格

<div class="col-lg-12">
            <div class="ibox-content">
                <div class="row">
                        <%= simple_form_for supplier_fuel_prices_path(@supplier,@fuel_price), method: :post do |f| %>

控制器

class Supplier::FuelPricesController < Supplier::ApplicationController
  before_action :set_supplier

  def index
  end

  def new
    @fuel_price = @supplier.fuel_prices.build
  end

  def create
    @fuel_price = @supplier.fuel_price.build(fuel_price_params)
    if @fuel_price.save
      flash[:notice] = "You have successfully Added new Fuel Price."
      redirect_to supplier_fuel_prices_path
    else
      flash.now[:alert] = "Something went wrong. Please try again."
      render "new"
    end
  end

  private

  def fuel_price_params
    params.require(:fuel_price).permit(:regular, :medium, :premium, :diesel)
  end

  def set_supplier
    @supplier = User.find_by(params[:supplier_id])
  end
end

模特

用户模型has_many：fuel_prices，foreign_key :: supplier_id

燃油价格模型有belongs_to＆＃34;供应商＆＃34;，class_name：＆＃34;用户＆＃34;

提交表单时收到的错误是

没有路线匹配[POST]＆＃34; / supplier / fuel_prices / new＆＃34;

我的路线看起来像这样

 namespace :supplier do
    root to: 'dashboard#index', as: 'dashboard'
    resources :retailers
    resources :fuel_prices

  end

路线

supplier_fuel_prices_path GET /supplier/fuel_prices(.:format） POST /supplier/fuel_prices(.:format）supplier / fuel_prices #create

new_supplier_fuel_price_path GET /supplier/fuel_prices/new(.:format）supplier / fuel_prices #new

edit_supplier_fuel_price_path GET /supplier/fuel_prices/:id/edit(.:format）supplier / fuel_prices #edit supplier_fuel_price_path

Answer 1

您只是试图post走错路。以new结尾的网址通常是get请求。运行rake routes并确保您发布到正确的post路线并更新您的表单。

简单的表单和路由错误
