アプリケーションにデータをレーキしようとすると、このエラーが発生します。

次のようなJSONファイルがあります…</p> 

[{"code": "OCH", "name": "blah", "location": "Texas, United States"},…

私のdb：seedsは次のようになります：

Airport.delete_all
airport_codes = JSON.parse(File.read(Rails.root.join('db/airport_codes.json')))
airport_codes.each do |code|
  Airport.create!(code)
end

そして私のスタックトレース：

このようなレーキタスクを作成したことを願っています

task :<rake task name> => :environment do
   Airport.delete_all
   airport_codes = JSON.parse(File.read(Rails.root.join('db/airport_codes.json')))
   airport_codes.each do |code|
     Airport.create!(code)
   end
end

これも正しい場合は、airport.rb をレーキ ファイルにインクルードしてみてください。

require 'airport.rb'

、しかし、私が知る限り、上記のrakeタスク形式はあなたのために働くはずです
