我剛開始寫紅寶石軌道。我寫了一個控制器,但得到錯誤的數量的「參數(1爲0)」的錯誤,我不明白爲什麼。它沒有關於錯誤發生的信息?它有一個堆棧跟蹤的完整列表,但我的控制器文件不在那裏!紅寶石軌道調試輸出
在我的控制器中,我只有兩種方法,我將測試activemq。但是當我把控制器拿出來後,我得到了上面的錯誤,所以我把所有的代碼都註釋掉了,但是我仍然得到相同的錯誤。我無法弄清楚爲什麼。
我搜索谷歌的紅寶石調試,我還沒有發現任何有用的東西。
這裏是我的控制器來源:
class ActivemqTestController < ApplicationController
def send
#client = Stomp::Client.open("stomp://localhost:61613")
#station_id=101
#data = {'station_id' => station_id, 'username' => 'yangyanzhe'}
#client.publish('/listener/add', data)
end
def receive
#client = Stomp::Client.open("stomp://localhost:61613")
# Processing loop
#client.subscribe('/listener/add', headers) do |msg|
# Process your message here
# Your submitted data is in msg.body
#puts msg['username'] + " joined " + msg['station_id'] + "\n"
#client.acknowledge(msg)
#end
#client.join # Wait until listening thread dies
end
end
這是錯誤:
ArgumentError in Activemq testController#index
wrong number of arguments (1 for 0)

感謝您提前任何幫助。
O,那就是爲什麼。謝謝。我仍然認爲紅寶石可能會給我一個有意義的消息 – Darkerstar 2010-03-24 08:16:03
我想知道爲什麼rails使用'.send'而不是'__send__'。 – 2010-03-24 23:01:23
