我有一个在我的本地服务器上呈现的静态登录页面（students / index.html.erb）;但是，当我将它推送到Heroku时，默认的public / index.html文件呈现而不是着陆页。当我删除public / index.html时，会提供public / 500.html。
我正在努力解决这个问题。希望以下信息有助于解释我的情况：
routes.rb中：
AlumniKickstarter::Application.routes.draw do
resources :students
# match '/', to: 'students#index'
root :to => 'students#index'
的Gemfile：
source 'https://rubygems.org'
gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
group :development do
gem 'sqlite3', '1.3.5'
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'
gem 'twitter-bootstrap-rails'
gem 'libv8', '~> 3.11.8'
gem 'less-rails'
gem 'therubyracer'
end
gem 'jquery-rails'
group :production do
gem 'pg', '0.12.2'
end
