我刚开始写ruby-rails。我写了一个控制器,但得到的“参数(0为1)”错误的数目,我不明白为什么。它没有错误发生在哪里的信息?它有一个完整的堆栈跟踪列表,但我的控制器文件不在那里!
在我的控制器中,我只有两个方法,我要测试activemq。但是在我把控制器放出来之后,我得到了上面的错误,所以我注释掉了所有的代码,但是我仍然得到了同样的错误。我不明白为什么。
我在google上搜索ruby debug,没有发现任何有用的东西。
这是我的控制器源:
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)
