我刚开始写红宝石轨道。我写了一个控制器,但得到错误的数量的“参数(1为0)”的错误,我不明白为什么。它没有关于错误发生的信息?它有一个堆栈跟踪的完整列表,但我的控制器文件不在那里!红宝石轨道调试输出
在我的控制器中,我只有两种方法,我将测试activemq。但是当我把控制器拿出来后,我得到了上面的错误,所以我把所有的代码都注释掉了,但是我仍然得到相同的错误。我无法弄清楚为什么。
我搜索谷歌的红宝石调试,我还没有发现任何有用的东西。
这里是我的控制器来源:
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
这是错误:
ArgumentError in Activemq testController#index
wrong number of arguments (1 for 0)

感谢您提前任何帮助。
O,那就是为什么。谢谢。我仍然认为红宝石可能会给我一个有意义的消息 – Darkerstar 2010-03-24 08:16:03
我想知道为什么rails使用'.send'而不是'__send__'。 – 2010-03-24 23:01:23
