Question

更新：我的答案在下面，简单的.merge是需要的。

我需要从build_virtual_boards_hash方法获取散列哈希作为输出我无法弄清楚如何将哈希添加到哈希堆栈中。甚至如何创建这样的东西......首先我会列出方法，然后向你展示我得到的输出。

以下是使用的两种方法...问题位于'build_virtual_boards_hash'...

def build_virtual_boards_hash(board, player)
  virtual_board = board.dup

  virtual_board_hash = {}
  new_board_hash = {}

  empty_spaces_on_board = virtual_board.grid.select{ |k, v| v == " " }.keys
  index_mark = 'VB'+empty_spaces_on_board.length.to_s

  #THIS IS WHERE I THINK THE PROBLEM IS
  #HOW DO I ADD EACH LOOP RESULT TO -SOMETHING- 
  #THAT CAN BE CALLED ON LATER AFTER THE LOOP ENDS
  #SO I GET THE DESIRED RESULTING OUTPUT?
  # 
  empty_spaces_on_board.each do |empty_space_symbol|
    # create a hash
    new_board_hash = {index_mark => move_as_somebody(board, player, empty_space_symbol).grid} #value
    p new_board_hash  
  end

end


#takes board....returns new board
def move_as_somebody(board, player, empty_space)
  new_board = board
  if player == 'X'
    new_board.grid[empty_space] = player
  else
    player == 'O'
    new_board.grid[empty_space] = player
  end
  return new_board
end

我目前从这两种方法得到这个输出......

{"VB7"=>{:a1=>"X", :a2=>"X", :a3=>" ", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}}
{"VB7"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}}
{"VB7"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}}
{"VB7"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>" ", :c2=>" ", :c3=>" "}}
{"VB7"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>"X", :c2=>" ", :c3=>" "}}
{"VB7"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>"X", :c2=>"X", :c3=>" "}}
{"VB7"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>"X", :c2=>"X", :c3=>"X"}}

我需要的是......

virtual_boards = {
    {"VB7"=>{:a1=>"X", :a2=>"X", :a3=>" ", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}},
    {"VB6"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}},
    {"VB5"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}},
    {"VB4"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>" ", :c2=>" ", :c3=>" "}},
    {"VB3"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>"X", :c2=>" ", :c3=>" "}},
    {"VB2"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>"X", :c2=>"X", :c3=>" "}},
    {"VB1"=>{:a1=>"X", :a2=>"X", :a3=>"X", :b1=>"X", :b2=>"O", :b3=>"X", :c1=>"X", :c2=>"X", :c3=>"X"}}
}

我如何做到这一点？

Answer 1

哈希哈希的问题通常是如何初始化深度哈希。

此问题已经解决并存入Ruby Facetes

h = Hash.autonew

现在您可以通过以下方式轻松初始化哈希：

h[:h1][:key] = 'value'
h[:h2][:key] = 'value'
...

Answer 2

答案是....

#builds hash of hash of fake boards
def build_virtual_boards_hash(board, player)
  virtual_board = board.dup
  i = 0
  virtual_board_hash = {}
  new_board_hash = {}

  empty_spaces_on_board = virtual_board.grid.select{ |k, v| v == " " }.keys


  while i < empty_spaces_on_board.length do
    p empty_space_symbol = empty_spaces_on_board[i]
    p index_mark = 'VB'+i.to_s

    new_board_hash = {index_mark => move_as_somebody(board, player, empty_space_symbol).grid}

    virtual_board_hash = virtual_board_hash.merge(new_board_hash)        

    i += 1
  end
  p virtual_board_hash
end
