Question

有2个应用App1和App2，我正在尝试使用items

从App1创建App2 ActiveResource表中的条目

我希望这项工作：

new_item = App2::Item.create(:property1 => "foo", :property2 => "bar")

这就是我在做的事情：

在App1中：

module App2
    class Item < ActiveResource::Base
        self.site = "http://localhost:3001" # This is where App2 is running
        self.prefix = "api/create_item/"
        def self.create(params)
            begin
                @item = App2::Item.new(:property1 => params[:property1], :property2 => params[:property2] )
                if @item.save
                  format.xml { render :xml => @item, :status => :created, :location => @item }
                else
                  format.xml { render :xml => @item.errors, :status => :unprocessable_entity}
                end
              rescue ActiveResource::ResourceNotFound => ex
                puts ex.message
              end
        end
    end
end

在App2中，CONTROLLER：

    module App2
        class ItemController < ApplicationController
            def create_item
                begin
                    @item = Item.new(:property1 => "foo", :property2 => "bar")
                    @item.save
                    respond_to do |format|
                      if @item.save
                        format.xml { render :xml => %Q[
                <?xml version="1.0" encoding="UTF-8"?>
                    <item>
                    <property1>#{item.property1}</property1>
                    <property2>#{item.property2}</property2>
                    </item>
                    ], :status => 200 }
                      else
                        format.xml { render :xml => %Q[<?xml version="1.0" encoding="UTF-8"?><error>Item was not created</error>], :status => 404 }
                      end
                    end
                  rescue Exception => ex
                        format.xml { render :xml => %Q[<?xml version="1.0" encoding="UTF-8"?><error>Item was not created. REASON: #{ex.message}</error>], :status => 404 }
                  end
            end
        end
    end

App2，ROUTE：

map.connect 'api/create_item', :controller => 'app2/item', :action => "create_item", :conditions => {:method => :post}

当我评论self.prefix = "api/create_item/"时，我在App2尾部看到了一些动作：

Processing ApplicationController#routes_catchall (for 10.104.232.160 at 2010-06-22 13:07:01) [POST]
  Parameters: {"item"=>{"property1"=> "abc", "property2"=>"def"}, "action"=>"routes_catchall", "path"=>["items.xml"], "controller"=>"application"}
Rendering template within layouts/error
Rendering error/404 (404 Not Found)
Completed in 743ms (View: 726, DB: 1) | 404 Not Found [http://localhost:3001/items.xml]

和App1中的Failed with 404 Not Found

当我使用前缀时，我看不到任何动作。

我搞砸了什么？

好吧，我刚发现问题:)
问题在于路由中没有能力响应xml格式。所以我不得不改变路线

map.connect 'api/create_item/items.:format', :controller => 'app2/item', :action => "create_item", :conditions => {:method => :post}

我（实际上我的朋友）通过记录它在connection.rb文件中点击的确切网址来调试它。

希望这有助于某人：）
