我有一系列散列名称和电子邮件,如下所示：
array = [{"email"=>"test@test.com","name"=>"Test"},{"email"=>"testA@gmail.com","name"=>"Test A"},{"name"=>"Test B","email"=>"testB@test.com"},{"email"=>"testC@yahoo.com","name"=>"Test C"},{"name"=>"Test D","email"=>"testD@hotmail.com"},{"email"=>"testE@test.com"},{"name"=>"Test F","email"=>"testF@test.com"}]
我想过滤掉“黑名单”数组中的某些电子邮件.以下作品,但它太冗长了.
blacklist = ["@test.com","@gmail.com"]
na = array
blacklist.each do |b|
na = na.reject{ |e| e["email"].include?(b) }
end
# na => [{"email"=>"testC@yahoo.com","email"=>"testD@hotmail.com"}]
有人可以通过把它变成性感的Ruby单行来帮助我吗？
解决方法
还有一个建议:)
array.reject { |h| blacklist.any? { |b| h["email"].include? b } }
