開発データベースで一連のレコード (200k) を更新する必要がありますが、Rails コンソールを介してクエリを実行すると、コンピューターがチョークします (コンソールがクエリの結果を出力するため)。

例：

1.9.3p194 :083 > Player.first
 => #<Player id: 1, IsActive: false, IsVisible: false, FirstName: "Ovie", LastName: "Soko", HeightFeet: 6, HeightInches: 8, Weight: 210, Birthday: nil, Gender: "M", HometownCity: "London", HometownState: "", HometownZip: "", HometownCountry: "", HighSchoolId: "", HighSchoolIdTemp: 0, HighSchoolGradYear: "2009", CollegeYear: "", Redshirted: false, Transferred: false, CollegeId: "{299F909C-88D9-4D26-8ADC-3EC1A66168BB}", CollegeIdTemp: 844, CollegeGradYear: "2013", OtherAccountId: 0, PreviousCollegeId: 0, CurrentTeamId: 0, LateralRecommendationReason: "", LateralRecommendationLink: "", CreationDate: "2011-02-16 20:53:34.877000000", CreatedBy: "", LastModifiedDate: "2011-02-16 20:53:34.877000000", LastModifiedBy: "", TwitterLink: "", FacebookLink: "", PersonalWebsite: "", PlayerImage: "", FirstNameNickName: "", NeulionID: 0, OtherTeamID: 0, OtherSportTypeID: 0, SourceDataTypeID: 1, PlayerTypeID: 2, LoadID: "", SameNameTeammate: "", SameNameSchoolMate: "", SD_SportID: 0, SD_PlayerID: 0, ZeroNCAAStats: "", ModifiedByPythonGame: "", Missing2011: "", Transfer2011: "", RecruitingClass: "\r", created_at: nil, updated_at: nil, high_school_id: nil, high_school_name: nil, not_valid: nil, city_to_zip_id: nil, user_id: nil>

おわかりのように、20 万件のレコードを印刷するのは難しいことではありません。

ここで解決策を試しました: Disable Rails SQL logging in consoleですが、その後もログ出力が得られます。

1.9.3p194 :087 > old_logger = ActiveRecord::Base.logger
 => #<Logger:0x007feb04b8de58 @progname=nil, @level=1, @default_formatter=#<Logger::Formatter:0x007feb04b8dde0 @datetime_format=nil>, @formatter=#<Logger::SimpleFormatter:0x007feb04b8dc50 @datetime_format=nil>, @logdev=#<Logger::LogDevice:0x007feb04b8dcf0 @shift_size=nil, @shift_age=nil, @filename=nil, @dev=#<IO:<STDERR>>, @mutex=#<Logger::LogDevice::LogDeviceMutex:0x007feb04b8dcc8 @mon_owner=nil, @mon_count=0, @mon_mutex=#<Mutex:0x007feb04b8dc78>>>> 
1.9.3p194 :088 > ActiveRecord::Base.logger = nil
 => nil 
1.9.3p194 :089 > Player.first
 => #<Player id: 1, IsActive: false, IsVisible: false, FirstName: "Ovie", LastName: "Soko", HeightFeet: 6, HeightInches: 8, Weight: 210, Birthday: nil, Gender: "M", HometownCity: "London", HometownState: "", HometownZip: "", HometownCountry: "", HighSchoolId: "", HighSchoolIdTemp: 0, HighSchoolGradYear: "2009", CollegeYear: "", Redshirted: false, Transferred: false, CollegeId: "{299F909C-88D9-4D26-8ADC-3EC1A66168BB}", CollegeIdTemp: 844, CollegeGradYear: "2013", OtherAccountId: 0, PreviousCollegeId: 0, CurrentTeamId: 0, LateralRecommendationReason: "", LateralRecommendationLink: "", CreationDate: "2011-02-16 20:53:34.877000000", CreatedBy: "", LastModifiedDate: "2011-02-16 20:53:34.877000000", LastModifiedBy: "", TwitterLink: "", FacebookLink: "", PersonalWebsite: "", PlayerImage: "", FirstNameNickName: "", NeulionID: 0, OtherTeamID: 0, OtherSportTypeID: 0, SourceDataTypeID: 1, PlayerTypeID: 2, LoadID: "", SameNameTeammate: "", SameNameSchoolMate: "", SD_SportID: 0, SD_PlayerID: 0, ZeroNCAAStats: "", ModifiedByPythonGame: "", Missing2011: "", Transfer2011: "", RecruitingClass: "\r", created_at: nil, updated_at: nil, high_school_id: nil, high_school_name: nil, not_valid: nil, city_to_zip_id: nil, user_id: nil>

Rails 3.2.1 の新しいハックがありますか、それとも何か間違っていますか?

最後のステートメントの結果をコンソールに出力する必要はありません。これは少し不自然な例ですが、最後のステートメントを nil にすることができます:

irb(main):156:0> Player.update_all(:IsActive => true); nil

SQL (1.8ms)  UPDATE "players" SET "IsActive" = 't'
=> nil

私はあなたが何か悪いことをしているとは思わない。Player.allすべてを返しますか？私の推測では、表示される出力はActiveRecordロガーではなくRailsメインロガーである可能性があります。

おそらく、これらのいずれかをnilに設定できますdevelopment.rb。
