Question

我正在存储Hash of Hash。

filelists { filename => [another hash] }
anotherhash {id => method}

其中filename是文件名，id是服务器id，method是锁，读或写的类型。

def addfile(client, input)
  #byebug
  serverid = input.split(' ')[2].strip
  filename = input.split(' ')[1].strip
  puts "RECEIVED FILE NOTIFICATION: " + serverid + " FILENAME: " + filename
  if @filelists.include?(filename)
    @filelists[filename] = {serverid.to_i => 'r'}
  else
    @filelists[filename] = Hash.new
    @filelists[filename] = {serverid.to_i => 'w'}
    puts "New Hash Created for: " + filename
  end
  client.puts "File Accepted: " + filename
  puts "File Accepted: " + filename + "\n\n"
  printfiles(filename)
end

当向哈希中添加另一个元素时，它只会删除前一个元素。

第一台服务器上传文件后，有：

 {"ds.txt"=>{1=>"w"}, "fileserver.rb"=>{1=>"w"}}

然后，当第二台服务器开始上传文件时，它只会重写上一个哈希值。

任何意见/建议都将不胜感激。

使用了错误的格式。需要改为

@filelists[filename][serverid.to_i] = 'r'

最终代码

def addfile(client, input)
#byebug
serverid = input.split(' ')[2].strip
filename = input.split(' ')[1].strip
puts "RECEIVED FILE NOTIFICATION: " + serverid + " FILENAME: " + filename
if @filelists.include?(filename)
  @filelists[filename] = {serverid.to_i => 'r'}
else
 **@filelists[filename][serverid.to_i] = 'r'**
  puts "New Hash Created for: " + filename
end
client.puts "File Accepted: " + filename
puts "File Accepted: " + filename + "\n\n"
printfiles(filename)
end

Hash的Ruby Hash，添加新项目
