我有两个散列数组:
[{:status=>"failed", :tag=>"tag156", :node=>"isfw-a"},
{:status=>"unchanged", :tag=>"tag156", :node=>"ayfw-a"},
{:status=>"changed", :tag=>"tag156", :node=>"vpfw-a"}]
[{:status=>"success", :sender=>"ayfw-a"},
{:status=>"success", :sender=>"vpfw-a"}]
我可以用来合并的键是:node
和:sender
。我需要将第二个数组中的:status
参数添加到第一个数组中,作为:another_status
,在第二个阵列中没有相应:sender
的地方放入"跳过",如下所示:
[{:status=>"failed", :tag=>"tag156", :node=>"isfw-a", :another_status=>"skipped"},
{:status=>"unchanged", :tag=>"tag156", :node=>"ayfw-a", :another_status=>"success"},
{:status=>"changed", :tag=>"tag156", :node=>"vpfw-a", :another_status=>"success"}]
我无法想出实现这一点的解决方案。
可能是这样的吗?
a1 = [
{:status=>"failed", :tag=>"tag156", :node=>"isfw-a"},
{:status=>"unchanged", :tag=>"tag156", :node=>"ayfw-a"},
{:status=>"changed", :tag=>"tag156", :node=>"vpfw-a"},
]
a2 = [
{:status=>"success", :sender=>"ayfw-a"},
{:status=>"success", :sender=>"vpfw-a"},
]
sender_status = Hash[ a2.map { |item| [ item[:sender], item[:status] ] } ]
a1.each do |item|
item[:another_status] = sender_status[item[:node]] || 'skipped'
end
a1.each { |item| p item }
输出
{:status=>"failed", :tag=>"tag156", :node=>"isfw-a", :another_status=>"skipped"}
{:status=>"unchanged", :tag=>"tag156", :node=>"ayfw-a", :another_status=>"success"}
{:status=>"changed", :tag=>"tag156", :node=>"vpfw-a", :another_status=>"success"}
a1 = [{:status=>"failed", :tag=>"tag156", :node=>"isfw-a"},
{:status=>"unchanged", :tag=>"tag156", :node=>"ayfw-a"},
{:status=>"changed", :tag=>"tag156", :node=>"vpfw-a"}]
a2 = [{:status=>"success", :sender=>"ayfw-a"},
{:status=>"success", :sender=>"vpfw-a"}]
a1.map do |h1| h1.merge(another_status:
a2.find{|h2| h2[:sender] == h1[:node]}.to_h[:status] || "skipped"
) end
输出

:tag => "tag156",

:another_status => "skipped"
