如果项与字符串数组匹配,则从Ruby哈希数组中删除项

它看起来像你的 hash_list 缺少右括号。我在下面添加了它们。尝试在irb中运行此命令:

playlist_track_names = ["I Might", "Me & You", "Day 1", "I Got You (feat. Nana Rogues)", "Feels So Good (feat. Anna of the North)", "306", "Location Unknown (feat. Georgia)", "Crying Over You (feat. BEKA)", "Shrink", "I Just Wanna Go Back", "Sometimes", "Forget Me Not"] 

hash_list = [
  {"id"=>"1426036284", "type"=>"songs", "attributes"=>{"name"=>"I Might", "albumName"=>"Love Me / Love Me Not" } },
  {"id"=>"1426036285", "type"=>"songs", "attributes"=>{"name"=>"Feels So Good (feat. Anna of the North)", "albumName"=>"Love Me / Love Me Not" } },
  {"id"=>"1426036286", "type"=>"songs", "attributes"=>{"name"=>"Forget Me Not", "albumName"=>"Love Me / Love Me Not" } },
  {"id"=>"1426036287", "type"=>"songs", "attributes"=>{"name"=>"Some Other Name", "albumName"=>"Love Me / Love Me Not" } }
]

hash_list.delete_if { |i| playlist_track_names.include? i["attributes"]["name"] }
puts hash_list

你可以用 Array#delete_if 删除与块匹配的任何条目。在街区使用 Array#include?

tracks.delete_if { |track|
  playlist_track_names.include? track["attributes"]["name"]
}

请注意,因为 playlist_track_names.include? 必须搜索 playlist_track_names 一个接一个的速度会变慢 播放列表\曲目\名称 Set

require 'set'

playlist_track_names = ["I Might", "Me & You", ...].to_set

收集 快速查找的值。 播放列表\u曲目_姓名。包括? 播放列表\曲目\名称 得到。
