Add .pluck_to_hash to ActiveRecord. The result will get the columns specified as keys for the hash and their values.

ActiveRecordPluckToHash.rb

module ActiveRecordPluckToHash
  def pluck_to_hash(*keys)
    formatted_keys = keys.map do |k|
      "'#{k.to_s.split(/\b.\b/i)[-1].strip}', #{k}"
    end.join(', ')

    pluck(Arel.sql("json_build_object(#{formatted_keys})")).map(&:with_indifferent_access)
  end
end

ActiveRecord::Relation.send :include, ActiveRecordPluckToHash

# Usage: Skill.where(id: 10).pluck_to_hash(:id, :name, :category) => [{'id' => 10, 'name' => 'HTML', 'category' => 'Programming'}]
