ruby-on-rails – 在Ruby on Rails中正确使用REJECT方法 – 帮助

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？
