我在 heroku 上的应用程序出现应用程序错误。 这是日志：

这是我的 gemfile：

source 'https://rubygems.org'
ruby '1.9.3'

gem 'rails', '3.2.13'
gem 'jquery-rails', '2.0.2'
gem 'haml-rails'
gem 'bcrypt-ruby', '~> 3.0.0'

group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.11.0'
end

group :development do
  gem 'better_errors'
  gem 'binding_of_caller'
end

group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
  gem 'zurb-foundation', '~> 4.0.0'
end

group :test do
  gem 'capybara', '1.1.2'
end

group :production do
  gem 'pg'
end

我不知道该怎么办。我搜索但没有找到一些 gem 来改善日志错误，例如本地的 better_erros gem。有没有类似的宝石？无论如何，我需要解决这个大问题！ 请给我光！ 谢谢！

Answer 1

发生的情况是，当您的应用程序在生产模式下运行时，它不会响应“设计”方法。这通常意味着您尚未加载 ORM 文件或加载得太晚。要修复它，请务必在 'config/initializers/devise.rb' 内或在 'config/application.rb' (RuntimeError) 中的应用程序定义之前添加 require 'devise/orm/active_record'。

所以你的devise.rb应该有以下内容

# ==> ORM configuration
  # Load and configure the ORM. Supports :active_record (default) and
  # :mongoid (bson_ext recommended) by default. Other ORMs may be
  # available as additional gems.
  require 'devise/orm/active_record'

只有我一个人。我相信我在您的 gemfile 中看不到 gem 'devise' ！难怪这可能会引发错误。
