Heroku Rails應用程序不允許通過設計登錄/註銷

Question

我目前的項目似乎有登錄/註銷的問題，但僅在生產（返回500錯誤）。當我在開發中本地運行它時，一切都很順利。這些頁面出現，只有當我成功輸入我的登錄信息或嘗試註銷時纔會出現錯誤。我已經通過代碼，查看了heroku日誌等，但我無法解決問題。有些東西讓我覺得它是由於我的郵件程序在環境/開發和生產文件中，但可能不是？

我一直在檢查整天，無法解決此問題。它昨天工作得很好，我還會補充說我已經嘗試遷移到heroku，但仍然沒有。那只是返回：ActiveRecord::SchemaMigration Load (2.8ms) SELECT "schema_migrations".* FROM "schema_migrations"。這是我的文件是這樣的：

環境/開發：

Rails.application.configure do 
# Settings specified here will take precedence over those in config/application.rb. 

# In the development environment your application's code is reloaded on 
# every request. This slows down response time but is perfect for development 
# since you don't have to restart the web server when you make code changes. 
config.cache_classes = false 

# Do not eager load code on boot. 
config.eager_load = false 

# Show full error reports and disable caching. 
config.consider_all_requests_local  = true 
config.action_controller.perform_caching = false 

# Don't care if the mailer can't send.

# Print deprecation notices to the Rails logger. 
config.active_support.deprecation = :log 

# Raise an error on page load if there are pending migrations. 
config.active_record.migration_error = :page_load 

# Debug mode disables concatenation and preprocessing of assets. 
# This option may cause significant delays in view rendering with a large 
# number of complex assets. 
config.assets.debug = true 

# Asset digests allow you to set far-future HTTP expiration dates on all assets, 
# yet still be able to expire them through the digest params. 
config.assets.digest = true 

# Adds additional error checking when serving assets at runtime. 
# Checks for improperly declared sprockets dependencies. 
# Raises helpful error messages. 
config.assets.raise_runtime_errors = true

# Use a different logger for distributed setups.

# config.action_mailer.raise_delivery_errors = false 

# Enable locale fallbacks for I18n (makes lookups for any locale fall back to 
# the I18n.default_locale when a translation cannot be found). 
config.i18n.fallbacks = true

這似乎是什麼Heroku的數收益：

您可能會提供的任何信息將非常感激！我只是堅持不知道該從哪裏出發。非常感謝。

編輯：這是我的模型對9號線：

before_save :http_protocol 

def http_protocol 
    unless self.website[/\Ahttp:\/\//] || self.website[/\Ahttps:\/\//] 
    self.website = "http://#{self.website}" 
    end 
end

Answer 1

您保存之前過濾http_protocol嘗試匹配用戶的website與正則表達式：

self.website[/\Ahttp:\/\//] 

這根據您的日誌文件失敗，因爲website是nil。

爲避免你需要檢查的website首先存在這樣的問題，請更改的方法是這樣的：

def http_protocol 
    if website.present? 
    self.website = "http://#{self.website}" unless website[/\Ahttps?:\/\//] 
    end 
end
