通过哈希遍历数组

Question

里面我有一个存储过程返回单个阵列内的以下散列：

@cars = [{"make"=>"honda"}, {"color"=>"black"}, {"make"=>"acura"}, {"color"=>"red"}] 

如何我将通过每一种迭代，这样我可以正确地把它们放进表。导致：

<table> 
    <tr> 
    <td>honda</td> 
    <td>black</td> 
    </tr> 
    <tr> 
    <td>acura</td> 
    <td>red</td> 
    </tr> 
</table> 

Answer 1

我会改变数据的格式红宝石：

@good_cars = @cars.each_slice(2).map { |a,b| a.merge(b) } 
# returns [{"make"=>"honda", "color"=>"black"}, {"make"=>"acura", "color"=>"red"}] 

Answer 2

<table> 
<% @cars.each_slice(2) do |hash1, hash2| %> 
    <tr> 
    <td><%= hash1['make'] %></td> 
    <td><%= hash2['color'] %></td> 
    </tr> 
<% end %> 
</table>
