Question

我正在使用此example for uploading files in Ruby on Rails.

我在路由方面遇到了一些问题：

错误：

ActionController::RoutingError (No route matches {:action=>"show", :controller=>"cars", :locale=>#<Car id: 19, car_name: "bwl",, created_at: "2013-01-27 19:12:13", updated_at: "2013-01-27 19:12:13">}):
  app/models/arraydb.rb:46:in `to_jq_car'

我发现问题出现在to_jq_car函数和行中：

"delete_url" => car_path(self)

但我不知道如何纠正它。

routes.rb中：

resources :cars
match '/show', :to =>'car#index'

root :to => 'cars#index'

cars_controllers.rb

class CarsController < ApplicationController


  def index
    @cars = Car.all

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @cars.map{|car| car.to_jq_car } }
    end
  end


  def show
    @car = Car.find(params[:id])

    respond_to do |format|
      format.html 
      format.json { render json: @car }
    end
  end

end

并在car.rb中我有以下功能：

 def to_jq_car
    {
      "name" => (read_attribute(:arraydb_name)).split(".").first,
      "url" => car.url(:original),
      "delete_url" => car_path(self),
      "delete_type" => "DELETE",


    }
  end

rake routes：

cars GET        (/:locale)/cars(.:format)                                  cars#index {:locale=>/en|de|es|ru|zh_cn|ar/}
POST       (/:locale)/cars(.:format)                                  cars#create {:locale=>/en|de|es|ru|zh_cn|ar/}
new_car GET        (/:locale)/cars/new(.:format)                              cars#new {:locale=>/en|de|es|ru|zh_cn|ar/}
edit_car GET        (/:locale)/cars/:id/edit(.:format)                         cars#edit {:locale=>/en|de|es|ru|zh_cn|ar/}
car GET        (/:locale)/cars/:id(.:format)                              cars#show {:locale=>/en|de|es|ru|zh_cn|ar/}
PUT        (/:locale)/cars/:id(.:format)                              cars#update {:locale=>/en|de|es|ru|zh_cn|ar/}
DELETE     (/:locale)/cars/:id(.:format)                              cars#destroy {:locale=>/en|de|es|ru|zh_cn|ar/}
show            (/:locale)/show(.:format)                                      car#index {:locale=>/en|de|es|ru|zh_cn|ar/}
root            /(:locale)(.:format)                                           cars#index {:locale=>/en|de|es|ru|zh_cn|ar/}

提前致谢

Answer 1

错误原因：locale param

你有路线

cars#index {:locale=>/en|de|es|ru|zh_cn|ar/}

所以：locale值必须是列表en|de|es|ru|zh_cn|ar

中的一个

你需要找到你把这个参数传递给控制器并将其更正的地方

您可以在ApplicationController中使用（或者您已经使用过）

def default_url_options
  {:locale => I18n.locale}
end

Ruby On Rails：ActionController :: RoutingError没有路由匹配，动作显示
