Question

是否有可能在方法中达到方法？例如：

class HardWorker < WebsocketRails::BaseController
  def perform
    self.main_method
  end

  def main_method
    puts "main method"

    def simple_method  # how to call this from outisde?
      puts "simple method"
    end

    def another_method
      puts "another_method"
      # do stuff
    end
    another_method     #start running "another method in background"
  end
end

我需要在“主要方法”中找到“simple_method”。

WebsocketRails::EventMap.describe do  # now it works like that:
  subscribe :event_name, :to => HardWorker, :with_method => :main_method
end

触发:event_name后，我的控制台上显示"main method"。但我需要在那里写"simple method"，而无需重新启动main_method。我需要在simple_method内找到此main_method。 Becouse main_method已经在后台运行了，我需要在其中找到一个方法并做很多计算。我使用sidekiq，所以我不能使用main_method范围之外的全局变量。我想我需要它来工作：

WebsocketRails::EventMap.describe do  # i wish it works, but it doesn't
  subscribe :event_name, :to => HardWorker, :with_method => :main_method[:simple_method]
end

更新：我需要更新这个@global_object。如果我记得“main_method”，我会松开本地增加的@global_object。我需要它在本地增加，但我不记得main_method。

  def main_method

    @global_object = 0

    def simple_method
      @global_object += 100
    end

    def another_method
      (1..(2**(0.size * 8 -2) -1)).each do |number|
        # every second updating my data and sending to Redis DB
        @global_object++
        sleep 1
      end
    end
    another_method
  end

你要问的不太清楚，但是如果你想定义类方法，为什么不定义类方法？

class HardWorker < WebsocketRails::BaseController
  def perform
    self.main_method
  end

  def self.main_method
    puts "main method"
    self.simple_method
    self.another_method     #start running "another method in background"
  end

  def self.simple_method  # how to call this from outisde?
    puts "simple method"
  end

  def self.another_method
    puts "another_method"
    # do stuff
  end
end

是否可以在方法中调用方法？
