    RailsとiPhoneではじめるアプリケーション開発 の動かないところ

    ・iOSのサンプルコードが間違っている
    TPRegisterController.mからonSubmitメソッド がごっそり抜けている。
    https://gist.github.com/shinriyo/8234566
    のコードを追加しました。


    ・TPLoginController.hが誤っている。

    //- (void)onRegisterFacebook:(NSString *)email uid:(NSString *)uid;
- (void)onRegisterFacebook:(NSString *)email uid:(NSString *)uid username:(NSString *)username;

    →username引数がない。


    ・TPTravelCreateController.mのエラーメッセージが誤り 

    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"エラーが発生しました" message:@"メールアドレスまたはパスワードが間違っています"

    とあるが、そもそも旅行情報を登録するフォームなので、メールアドレスもパスワードも入力するところではない。

    ・P244のユーザのログイン時

    Started POST "/api/users/sign_in" for 127.0.0.1 at 2014-01-05 20:41:07 +0900
Processing by Api::SessionsController#create as */*
  Parameters: {"user"=>{"email"=>"shinriyo@gmail.com", "password"=>"[FILTERED]"}}
WARNING: Can't verify CSRF token authenticity
  User Load (0.4ms)  SELECT `users`.* FROM `users` WHERE `users`.`email` = 'shinriyo@gmail.com' LIMIT 1
   (0.2ms)  BEGIN
   (0.1ms)  COMMIT
Completed 401 Unauthorized in 76ms

    →「WARNING: Can't verify CSRF token authenticity」の警告が出る。

    →根本的な解決ではないが、app/controllers/application_controller.rb から「protect_from_forgery」を外す。
    または、
    app/controllers/api/sessions_controller.rb に「skip_before_filter :verify_authenticity_token」 を追加する。


    ちなみに、iPhone側のログには

    2014-01-05 21:05:09.264 travelphoto[44927:c07] Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Expected content type {(
    "text/json",
    "application/json",
    "text/javascript"

)}, got text/html" UserInfo=0xbe8c330 {NSLocalizedRecoverySuggestion=<!DOCTYPE html>

    が出力される。※Deviseがうまく認証できなくて「You have to confirm your account before continuing.」のエラーページが表示されるせい？

    Gemfile

    gem 'devise', '2.2.8'

    にして最新版が入らないようにインストールしています。

    →しかし、新しいdeviseだとtoken_authが利用できなくなっているので、2.2.4を利用する方がいいとのことなので、入れなおした。


    ◯Devise2.2.4版を入れなおした時のRailsに出てくるエラーメッセージ

    Started POST "/api/users/sign_in" for 127.0.0.1 at 2014-01-09 10:17:19 +0900
Processing by Api::SessionsController#create as */*
  Parameters: {"user"=>{"email"=>"shinriyo@gmail.com", "password"=>"[FILTERED]"}}
  User Load (2.3ms)  SELECT `users`.* FROM `users` WHERE `users`.`email` = 'shinriyo@gmail.com' LIMIT 1
   (0.2ms)  BEGIN
   (0.2ms)  COMMIT
Completed 401 Unauthorized in 238ms


Started GET "/users/sign_in" for 127.0.0.1 at 2014-01-09 10:17:19 +0900
Processing by Devise::SessionsController#new as */*
  Rendered users/shared/_links.haml (3.5ms)
  Rendered users/sessions/new.html.haml within layouts/application (19.1ms)
Completed 200 OK in 286ms (Views: 285.1ms | ActiveRecord: 0.0ms)

    Devise2.2.4を入れなおしたことにより、バージョンが古いのでセキュリティが甘くなったせいか、
    app/controllers/application_controller.rb から「protect_from_forgery」を外さなくても、
    「WARNING: Can't verify CSRF token authenticity」の警告は出なくなった。
    しかし、401のエラーが発生した。

    ・Xcodeには相変わらず同じエラーが発生
