我有以下数组

[["convertible", "2010", "red"], ["convertible", "2010", "green"]]

如何在rails或ruby中将上述数组合并到这个数组中?
["convertible", "2010", "red", "convertible", "2010", "green"]

编辑-1
@category.each do |content|
      form_chain = JSON.parse(content.content)
      chained_array << form_chain.values
    end

    chained_array

这就产生了
[["convertible", "2010", "red"], ["convertible", "2010", "green"]]

如果我使用chained_array.flatten!它会给出相同的结果。

最佳答案

[["convertible", "2010", "red"], ["convertible", "2010", "green"]].flatten!
