Я только что закончил главу 10 учебника по Ruby on Rails , добавив возможность редактировать / обновлять, индексировать и уничтожать пользователей.Кажется, что все работает правильно в моем приложении, но многие мои тесты не выполняются, когда я запускаю RSpec.
У меня настроен users_controller_spec точно так же, как в книге, и код моего приложения такой же.Может ли быть одна проблема, что я использую Rails 3.1.1, а не Rails 3.0, который он использует в книге?Это на самом деле не было проблемой для предыдущих тестов, иногда для нескольких разных строк кода.Проблемы начали появляться после того, как я начал раздел 10.2.1 .
Вот список ошибок, которые я вижу, и, пожалуйста, дайте мне знать, если вам нужна дополнительная информация.Спасибо!

ОБНОВЛЕНИЕ:
Я исправил 2 ошибки, но большинство все еще не устранены.Одна проблема заключается в том, что, когда тест пытается «получить: индекс», он не находит правильную страницу из-за перенаправления (на страницу / signin).Я не создавал никаких перенаправлений (намеренно в любом случае), но, возможно, у кого-то есть представление о том, как это могло произойти и как это можно исправить?
ОБНОВЛЕНИЕ № 2:
По запросу @ bkempner приведен соответствующий код из users_controller_spec и users_controller (сначала users_controller_spec).Много кода, но много ошибок ...:
