调试Heroku部署(500错误)

[英]Debugging Heroku Deployment (500 Error)

在过去的几个晚上我一直在努力将我的第一个rails应用程序部署到heroku,并且正在努力弄清楚如何解决这个问题。

我使用Michael Hartl的教程(http://ruby.railstutorial.org/chapters/beginning#sec-deploying)来确保我在Cedar Stack上设置我的应用程序。

根据Heroku教程,我使用“瘦”作为服务器。

我已经阅读了很多帖子并使用以下方法预编译了我的资产:

heroku run bundle exec rake assets:precompile bundle exec rake assets:precompile

我也迁移了我的数据库。

我的应用程序适用于我的localhost。

这是我的gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.8'
gem 'bootstrap-sass', '2.0.0'
gem 'bcrypt-ruby'
gem 'thin'

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

group :development do
  gem 'sqlite3'
end

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :production do
  gem 'pg'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

group :test do
  gem 'capybara'
  gem 'factory_girl_rails'
end

这是我的heroku日志

这看起来像是重要的部分:

ActionView::Template::Error (screen.css isn't precompiled):

似乎这个线程将解决您的问题。

正如它所说:

On heroku server (readonly filesystem), If you want runtime compilation of css (its not recommended but you can do it), make sure you have done settings like below -

# inside config/application.rb
config.assets.enabled = true
config.assets.prefix = Rails.root.join('tmp/assets').to_s

# If you are using sass then keep gem outside of asset group
 gem 'sass-rails',   '3.1.4'

# inside config/environments/production.rb
config.assets.compile = true

我在这里找到了答案: 蓝图css rails 3.1帮助

据我所知,这似乎是使用Blueprint CSS Framework的一个问题。 那说,另外两个说明:

  1. 我从application.html.erb布局文件中注释掉了<%= stylesheet_link_tag“屏幕”,:media =>“screen”%>代码。
  2. 我没有安装'rubyracer'宝石。 我安装它是因为它在引用答案的gem profile中。 我不知道它的作用。
  3. 现在,只要有链接,URL斜杠(“/”)就会再次出现。 我的预感是,它只是我需要深入研究和调试的一个CSS文件中的内容。 但是,我首先得到stylesheet_link_tag事情的全部原因是因为我试图摆脱那些讨厌的斜线。 最终,我认为部署更重要。

希望这对其他人有帮助!

以下是我最终解决问题的方法。 感谢那些把我推荐到别处的人,以便我可以把它们放在一起。

首先,我将Blueprint移动到了一个供应商目录。 我不认为这对解决方案至关重要,但感觉更清洁。

编译问题:

这个主题: 蓝图css rails 3.1帮助真的很有帮助。 我发现Martin和Gary的回答(第2和第3条)比选择的回答更有帮助。

我编译(个人)的部分原因是因为我对Blueprint文件进行了一些编辑,这意味着他们需要在部署之前再次编译。

这个线程: rails 3.1.0 ActionView :: Template :: Error(application.css未预编译)在这方面很有帮助。 基本上,在上传到heroku之前,只需运行“Bundle exec rake assets:precompile”。 上传后我还运行“heroku run rake assets:precompile”。

如何删除链接中的URL斜杠: URL是Blueprint / print.css中此代码的结果:

a:link, a:visited {background:transparent;font-weight:700;text-decoration:underline;}
a:link:after, a:visited:after {content:" (" attr(href) ")";font-size:90%;}

我通过注释掉那段代码解决了这个问题。 当然,在更改文件后,您必须耙资产:再次预编译。 但是,这一切都有效!
