紅寶石散在鑰匙串和價值

Question

你好我'紅寶石新的數組，我想拿到鑰匙用繩子散列和值的Array，就像這樣：

Hash = new HashMap 
for (issue :is) 
Hash.add(is.user_name) 
    if(hash.contains(is.user_name)) then 
    hash.value.add(is) 
    end 
end 

得到這樣的結果：

{"jane"[issue123,issue234,issue345]; "mike" [issue333,issue444,issue555]; "Alain" [issue876,issue987,issue356] } 

簡有[issue123，issue234，issue345]

感謝

東西LIK e如下：

result = Hash.new { |hash, key| hash[key] = [] } 

issues.each do |issue| 
    result[issue.user_name].push issue 
end
