Iterate array of hashes and display in dropdown in ruby

Question

my array of hash is the below one.

[{"status"=>"Submitted", "reachable"=>false}, 
{"status"=>"Replied", "reachable"=>false}, 
{"status"=>"Answered", "reachable"=>false}, 
{"status"=>"Assigned", "reachable"=>false}, 
{"status"=>"Started", "reachable"=>true}, 
{"status"=>"Closed", "reachable"=>false}, 
{"status"=>"Canceled", "reachable"=>true}]

I need the "status" values and display them in a dropdown in a html with embedded ruby code. Can anyone of you let me know the sample code ? I am pretty much new to ruby and getting confused alot in iterations and displaying the values in the dropdown.

Yes as below:

array = [{"status"=>"Submitted", "reachable"=>false}, 
        {"status"=>"Replied", "reachable"=>false}, 
        {"status"=>"Answered", "reachable"=>false}, 
        {"status"=>"Assigned", "reachable"=>false}, 
        {"status"=>"Started", "reachable"=>true}, 
        {"status"=>"Closed", "reachable"=>false}, 
        {"status"=>"Canceled", "reachable"=>true}]

p array.map{|h| h["status"] }
# >> ["Submitted", "Replied", "Answered", "Assigned", "Started", "Closed", "Canceled"]

@user19098 As per your question I gave this solution.. But don't know anything about ROR.. So can't help. But my answer will work 100% if you fit it properly in your code base..

Yes it works perfectly as you mentioned. I am able to get it as an array of status names. But was trying to get that names in a dropdown list !

@user19098 Use puts instead of p.. :)
