Ruby on rails 推送到heroku后无法访问应用程序

Ruby on rails 推送到heroku后无法访问应用程序,ruby-on-rails,ruby,heroku,gemfile,Ruby On Rails,Ruby,Heroku,Gemfile,在gemfile和config/application.rb文件中进行了一些操作之后,我将我的应用程序推送到了heroku 我在Bundler.require上方的application.rb文件中有config.assets.initialize\on\u precompile=false 这是档案 source 'https://rubygems.org' ruby '2.1.0' gem 'rails', '4.0.5' group :development, :test do

在gemfile和config/application.rb文件中进行了一些操作之后,我将我的应用程序推送到了heroku

我在Bundler.require上方的application.rb文件中有
config.assets.initialize\on\u precompile=false

这是档案

source 'https://rubygems.org'
ruby '2.1.0'

gem 'rails', '4.0.5'

group :development, :test do
    gem 'sqlite3'
end

group :production do
    gem 'pg'
end

gem 'sass-rails', '~> 4.0.2'

gem 'uglifier', '>= 1.3.0'

 gem 'bcrypt', '~> 3.1.7'

group :test, :development do
  gem "rspec-rails", "2.13.1"

group :test do
  gem "capybara", "2.1.0"
end

group :development do
    gem 'pry-rails'
    gem 'nokogiri', '1.6.3.1'
end
当我尝试访问heroku上的应用程序时,我得到一个:

'应用程序错误 应用程序中出现错误,无法提供您的页面。请稍后再试

如果您是应用程序所有者,请查看日志以了解详细信息。”

有什么想法吗

编辑:Application.rb按要求发布在下面:

require File.expand_path('../boot', __FILE__)

require 'rails/all'

config.assets.initialize_on_precompile = false

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Planner
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de
  end
end
需要文件。展开路径('../boot',文件)
需要“rails/all”
config.assets.initialize\u on\u precompile=false
#需要Gemfile中列出的宝石,包括任何宝石
#您仅限于:测试、开发或:生产。
Bundler.require(*Rails.groups)

类应用程序
它正在抱怨第5行的config语句。这需要在应用程序类定义中,如下所示:

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Planner
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    config.assets.initialize_on_precompile = false
  end
end

您检查日志了吗?(
heroku日志
)是。我看到:Slug编译失败:未能编译Ruby应用程序,以及:/app/config/application.rb:5:in
':main:Object(NameError)的未定义局部变量或方法
config')。您能发布您的application.rb文件吗?谢谢。你能解释一下这一行的必要性吗?有时候我推的应用程序需要它,但我真的不明白为什么在某些情况下需要它,而在其他情况下不需要它。奇怪的是,这个应用程序是因为这个错误而成功推出的。我真的不确定。一些快速研究表明,它曾经是Rails 3中的一个常见设置,但后来被弃用并从文档中删除。我在这里找到了一个参考:
