Question

我试图将参数从一个站点传递到下一个站点并使用它但我遇到了问题！

商店＆gt;索引

<h1>All Priorities</h1>


<% @buildings.each do |building| %>
<div class="entry">
    <div class="img">
    <%= image_tag (building.photo.url)%></div>
    <div class=" disc">
    <h3>Name of the Bulding:  <%= building.title %></h3>
     <h4>Status: <%= building.status %></h4>
    Info: <%=sanitize(building.description)%>
    <div class="price_line">
        <span class="price">Price: <%= sprintf("€ %0.02f",building.price)%></span><br/>
        <div class="button">
        <%= button_to "I Want to See it", new_seeit_path(building.id), :method => :get%>

</div>
    </div>
    </div>


    <%end%>
    <div class="pages">
    <%= will_paginate @buildings %></p>
    </div>

在下一个网站，当我按下按钮时我想看到它说：

http://localhost:3000/seeits/new.4?

并且不会打开页面

如果我删除（building.id），它会说：

http://localhost:3000/seeits/new?

它带我到下一个网站，但没有param

观看＆gt; wish_receive.text.erb＆lt; =这会在电子邮件中发送给我这些信息

You got a wish from   <%= @seeit.name %> 
<%= @seeit.telephone_number %>
<%= @seeit.email %>
<%= @seeit.comments %>

路由

Projectproperties::Application.routes.draw do
  resources :seeits

  get "about/index"

  get "contact/index"

  get "store/index"

  resources :buildings
 root :to => 'store#index', :as => 'store'
end

seeits_controller

def new
    @seeit = Seeit.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @seeit }
    end
  end

  # GET /seeits/1/edit
  def edit
    @seeit = Seeit.find(params[:id])
  end

  # POST /seeits
  # POST /seeits.json
  def create
    @seeit = Seeit.new(params[:seeit])

    respond_to do |format|
      if @seeit.save
        Notifier.wish_received(@seeit).deliver
        format.html { redirect_to(store_url, notice: 'Thank you for your wish will contac you very soon.') }
        format.json { render json: @seeit, status: :created, location: @seeit }
      else
        format.html { render action: "new" }
        format.json { render json: @seeit.errors, status: :unprocessable_entity }
      end
    end
  end

rake routes命令

      seeits GET    /seeits(.:format)             seeits#index
              POST   /seeits(.:format)             seeits#create
    new_seeit GET    /seeits/new(.:format)         seeits#new
   edit_seeit GET    /seeits/:id/edit(.:format)    seeits#edit
        seeit GET    /seeits/:id(.:format)         seeits#show
              PUT    /seeits/:id(.:format)         seeits#update
              DELETE /seeits/:id(.:format)         seeits#destroy
  about_index GET    /about/index(.:format)        about#index
contact_index GET    /contact/index(.:format)      contact#index
  store_index GET    /store/index(.:format)        store#index
    buildings GET    /buildings(.:format)          buildings#index
              POST   /buildings(.:format)          buildings#create
 new_building GET    /buildings/new(.:format)      buildings#new
edit_building GET    /buildings/:id/edit(.:format) buildings#edit
     building GET    /buildings/:id(.:format)      buildings#show
              PUT    /buildings/:id(.:format)      buildings#update
              DELETE /buildings/:id(.:format)      buildings#destroy
        store        /                             store#index

您能告诉我们您的routes.rb文件和rake路由输出吗？

我们走了。

在routes.rb文件中，添加：

  resources :seeits do
    member do 
      post 'new'
    end
  end

在seeits_controller.rb文件中，您的新方法应如下所示：

  def new
      # raise params.inspect
      @seeit = Seeit.new
      @building = Building.find(params[:building_id])

      respond_to do |format|
        format.html # new.html.erb
        format.json { render json: @seeit }
      end
    end

最后，在您的视图文件中，将button_to代码替换为此

<%= button_to("I want to see it", {:controller => "seeits", :action => "new", :building_id => building.id})%>

注意，现在，您的按钮将变量building_id作为参数传递，允许您访问@building对象。控制器中的新操作现在是一个post函数，因为我们正在向服务器发送信息。现在，您可以在新模板中使用@building。希望这会有所帮助。

用ror传递参数
