Question

我有一个简单的Sinatra应用程序。在本地机器上正常工作。

将它部署到Heroku，我不断在日志上获得404.

我保证我会在网上搜索大约5小时，并且无法解决这个问题。

我得到的日志是：

2014-11-08T00:17:12.537150+00:00 heroku[web.1]: Starting process with command `bundle exec rackup config.ru -p 51609`

我的 Gemfile 是这样的：

ruby '2.0.0'
source "https://rubygems.org"

gem 'sinatra-base'
gem 'sinatra-assetpack'
gem 'sinatra-asset-pipeline'
gem 'sass'
gem 'datamapper'
gem 'pony'

group :production do
    gem "pg"
    gem "dm-postgres-adapter"
end

group :development, :test do
    gem "sqlite3"
    gem "dm-sqlite-adapter"
end

Proclife：

web: bundle exec rackup config.ru -p $PORT

我用红宝石代替了机架和其他一些我找到的变种。

Config.ru

require './my_launch'
run Sinatra::Application

最后，我的应用：my_launch.rb ：

require 'sinatra/base'
require 'sinatra/assetpack'
require 'sass'
require 'data_mapper'
require 'dm-migrations'
require 'pony'

DataMapper.setup(:default, ENV['DATABASE_URL'] || "sqlite3://#{Dir.pwd}/mylaunch.db")

class Users
  include DataMapper::Resource
  property :id, Serial
  property :email, String, :required => true, :format => :email_address
  property :created_at, DateTime
end

DataMapper.finalize.auto_upgrade!


class MyLaunch < Sinatra::Base
  set :sessions, true
  register Sinatra::AssetPack

  assets do
     css :main, [
      '/css/*.css'
     ]
     css_compression :sass
  end

  get '/' do
    erb :index
  end

  post '/' do
    n = Users.new
    n.email = params[:email]
    n.created_at = Time.now
    n.save
    redirect '/obrigado'
  end

  get '/obrigado' do
    erb :obrigado
  end

  get '/admin' do
    @users = Users.all :order => :id.desc
    erb :admin
  end

  run! if app_file == $0
end

我的数据库似乎没问题。为了测试我启动了heroku控制台并在我的数据库上创建了一个条目。通过需要my_launch.rb并制作Users.new及以后的Users.save

在您的配置文件中，您的调用run Sinatra::Application不同于您的Sinatra继承类，其中定义了所有路由。将其更改为

require './my_launch'
run MyLaunch

在Ruby Sinatra App上获得404 - Heroku
