我有一个 id，它有一个嵌套在地图深处的匹配项。我需要找到匹配项并返回该地图。
不过，它比那要复杂一些。在这张大地图中，有称为homeand 的键away，我拥有的 id 可以嵌套在这些键中的任何一个中。
我正在尝试找到一种方法，基本上将这两个键平展为一个，以便我可以与所有值进行比较。
Map.take(game, ["away", "home"]) |> Map.get("players")
但这回 nil
更清楚一点：
这是我用来挖掘地图的方法：
defp evaluate_player_points(game, question) do
Map.get(game, "away")
|> Map.get("players")
|> Enum.find(fn %{"id" => id} -> question.player_id == id end)
|> Map.get("statistics")
|> Map.get("points")
end
但是正如您所看到的，顶部 Map.get 需要是动态的才能查找home或away

希望显示地图可以帮助您了解我要完成的任务。
players是一个列表。
Map.take(game, ["away", "home"])应该肯定有效，但是Kernel.get_in/2使用Access行为更惯用。
你需要的一切就是点缀Kernel.get_in/2用Enum.find/2的查找：
game
|> get_in(~w|away players|)
|> Enum.find(fn e -> CONDITION end)
|> get_in(~w|statistics points|)
如果您要发布 MCVE 而不是无效对象，我可以对此进行测试。
