Question

我试图在凤凰elixir的postgres中创建一个Geo Point对象数组。我得到错误类型_geometry无法由类型模块Terror.PostgrexType处理。

在Terror.Postgrextype中：

Postgrex.Types.define(Terror.PostgrexTypes,
[Geo.PostGIS.Extension] ++ Ecto.Adapters.Postgres.extensions(),
json: Poison)

我已成功将相关表格修改为 - ＆gt;

alter table(:terrorgrouplocations) do
 modify :geo_locs, {:array,:geometry}
end

相应的模型包含：

field :geo_locs, {:array, Geo.Point}

仍然是elixir的新手，并且可以真正使用一些指导！谢谢！

整个堆栈跟踪：
