Question

我尝试使用Heroku部署我的应用。我想我已经成功部署了它，但每当我尝试在浏览器上打开我的应用程序时，它就说......

应用程序错误应用程序和页面发生错误无法提供服务。如果您是应用程序所有者，请检查日志详情

当我输入heroku logs时，我得到......

2017-07-15T14:20:37.334994+00:00 heroku[web.1]: State changed from starting to crashed
2017-07-15T14:20:38.012558+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=deucex.herokuapp.com request_id=8a0d5560-e3bb-4cc2-82c3-9258db8eacb5 fwd="98.26.96.65" dyno= connect= service= status=503 bytes= protocol=https

我知道我的应用程序崩溃了，但我不知道为什么。我尝试输入heroku restart，但没有工作。我也尝试过查找这个问题，但没有成功。我该怎么办？

======更新=====

当我进入时：

$ heroku run rake db:create

我收到以下错误：

=====更新========

当我尝试跑步时：

$ rails server -b $IP -p $PORT

我明白了：

ActiveRecord :: NoDatabaseError致命：数据库＆＃34; sale_development＆＃34;不不存在

这是我的database.yml代码

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
default: &default
  adapter: postgresql
  encoding: unicode
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

development:
  <<: *default
  database: sale_development

test:
  <<: *default
  database: sale_test

production:
  <<: *default
  database: sale_production
  username: sale
  password: <%= ENV['SALE_DATABASE_PASSWORD'] %>

显然sale_development存在。销售是我的应用程序的名称。为什么说它不存在？

Answer 1

您是否创建了数据库？尝试heroku run rake db:create或heroku run rails db:create，然后迁移。

您收到消息sale_development不存在，因为当您推送到heroku时，它正在生产和生产中启动您的应用程序，您有另一个数据库。
