Hi, Jeremy.

Following is a example:

Jin10MessageCategory.dataset.map { _1.to_hash.slice(:id, :name) }

    {
          :id => 1,
        :name => "贵金属"
    },
    {
          :id => 2,
        :name => "石油"
    },
    {
          :id => 3,
        :name => "外汇"
    },
    {
          :id => 4,
        :name => "期货"
    },
}

Is there exists a more simple way to do this?

Thank you.

This would be my way to do it:

Jin10MessageCategory.select(:id, :name).naked.all

Yes, better.
