ubuntu rails s エラー

Question

railsの環境構築での質問です。
ubuntuでrails の環境構築中rails sとしたところ、エラーが表示されました。

/home/toshiki23/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/factory_bot-5.0.2/lib/factory_bot/definition_proxy.rb:97:in `method_missing': undefined method 'key' in 'ae_param' factory (NoMethodError)

と表示されました。

エラー全文はこちらになります。

以下、definition_proxy.rb、91行目からのコードとなります。

def method_missing(name, *args, &block) # rubocop:disable Style/MethodMissing
      if args.empty?
        __declare_attribute__(name, block)
      elsif args.first.respond_to?(:has_key?) && args.first.has_key?(:factory)
        association(name, *args)
      else
        raise NoMethodError.new(
          "undefined method '#{name}' in '#{@definition.name}' factory",
        )
      end
 end

definition_proxy.rbの内容は以下の通りです。

module FactoryBot
  class DefinitionProxy
    UNPROXIED_METHODS = %w(
      __send__
      __id__
      nil?
      send

      caller
      method
    ).freeze

    (instance_methods + private_instance_methods).each do |method|
      undef_method(method) unless UNPROXIED_METHODS.include?(method.to_s)
    end

    delegate :before, :after, :callback, to: :@definition

    attr_reader :child_factories

    def initialize(definition, ignore = false)
      @definition      = definition
      @ignore          = ignore

    end

    def singleton_method_added(name)
      message = "Defining methods in blocks (trait or factory) is not supported (#{name})"

    end

    # Adds an attribute to the factory.
    # The attribute value will be generated "lazily"
    # by calling the block whenever an instance is generated.
    # The block will not be called if the
    # attribute is overridden for a specific instance.
    #
    # Arguments:
    # * name: +Symbol+ or +String+
    #   The name of this attribute. This will be assigned using "name=" for
    #   generated instances.
    def add_attribute(name, &block)
      declaration = Declaration::Dynamic.new(name, @ignore, block)
      @definition.declare_attribute(declaration)
    end

    def transient(&block)
      proxy = DefinitionProxy.new(@definition, true)
      proxy.instance_eval(&block)
    end

    # Calls add_attribute using the missing method name as the name of the
    # attribute, so that:
    #
    #   factory :user do

    #   end
    #
    # and:
    #

    #   end
    #
    # are equivalent.
    #
    # If no argument or block is given, factory_bot will first look for an
    # association, then for a sequence, and finally for a trait with the same
    # name. This means that given an "admin" trait, an "email" sequence, and an
    # "account" factory:
    #
    #   factory :user, traits: [:admin] do
    #     email { generate(:email) }
    #     association :account
    #   end
    #
    # and:

    #     email
    #     account
    #   end
    #

また同じようなエラーの解決策を Qiitaで見つけたのですが該当箇所が異なり、未解決のままです。

同じような経験のある方いらっしゃいますでしょうか？

エラーの元は　 undefined method 'key' in 'ae_param' factory　です。
spec/factory に 問題があります。　ae_param　を探してみて下さい

[asm]

エラーログをpastebinやgistあたりにアップロードするなどの方法でよいので全文提示できますか？

[Toshinori23]

/home/toshiki23の以下の階層でspecと検索してみたのですが、spec/factoryというディレクトリは見つかりませんでした。

[Toshinori23]

pastebinにエラー全文表示させていただきました。

[winterboum]

ごめ　factories　でした、これはありませんか？

[Toshinori23]

ありました！
FactoryBot.define do ～～
の中の属性名を｛｝することで解決することができました！

エラーログを見るコツとして
まず、Tracebackの中から自分が書いた行を探し出すことです。
(ライブラリ側よりも、自分で書いたスクリプトの方が原因である事が圧倒的に多い)

今回のエラーログですと

49: from /mnt/c/pick_pro/PickGoManagerRuby/config/environment.rb:5:in `<top (required)>'
8: from /mnt/c/pick_pro/PickGoManagerRuby/spec/factories/auto_entries.rb:1:in `<top (required)>'
4: from /mnt/c/pick_pro/PickGoManagerRuby/spec/factories/auto_entries.rb:4:in `block in <top (required)>'
1: from /mnt/c/pick_pro/PickGoManagerRuby/spec/factories/auto_entries.rb:5:in `block (2 levels) in <top (required)>'

が、あなたが管理している筈の行になります。

エラーの内容から鑑みて/mnt/c/pick_pro/PickGoManagerRuby/spec/factories/auto_entries.rb:5がエラー発生行だと思います。

ズバリそこでした汗
エラー文をしっかり読もうと思います。。。
大変助かりました。ありがとうございました！
