将数组的值与哈希值组合

Question

我有一个由我定义的属性数组，我得到了一个哈希值，我需要将它们组合成一个输出数组。请告诉我最简单的方法。

属性 = [:user_id, :project_id, :task_id, :date, :time_spent, :comment]

entry_hash = {"User"=>1, "Project"=>[8], "Task"=>[87], "Date"=>"05/22/2017" , "时间(小时)"=>"1", "评论"=>"是"}

当它被组合时，我想要一个类似的哈希

输出 = {"user_id"=>1, "project_id"=>8, "task_id"=>87, "date"=>6/22/2017,"time_spent"=>1,"comment"=>"yes"}

感谢您的帮助！

试试这个

attributes = [:user_id, :project_id, :task_id, :date, :time_spent, :comment]
# puts attributes.inspect
entry_hash = {"User"=>1, "Project"=>[8], "Task"=>[87], "Date"=>"05/22/2017", "Time (Hours)"=>"1", "Comment"=>"yes"}
# puts entry_hash.inspect

output = {}
a = 0
entry_hash.each do |key,value|
    if value.class == Array
        output[attributes[a]] = value.first.to_s
        #output[attributes[a]] = value.first.to_i   //also you can convert them into int
    else
        output[attributes[a]] = value
    end
    a += 1

end
#puts output.inspect
#{:user_id=>1, :project_id=>"8", :task_id=>"87", :date=>"05/22/2017", :time_spent=>"1", :comment=>"yes"}
