Question

我很难将最新的rails 3.2应用程序推送到heroku。我之前没有遇到任何问题，我一直在推动它，自上次工作提交以来我所做的最新事情是为postgres添加了一个hstore列和一个模型的联合。这些都可以在我和其他计算机上完美运行。

正在运行

heroku run rake db：migrate我得到以下输出：

james@James-PC:~/tendersave$ heroku run rake db:migrate
Running `rake db:migrate` attached to terminal... up, run.1
DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/Rakefile:7)

注意最后一行的错误

同样在运行heroku run db：setup时我得到了这个：

james@James-PC:~/tendersave$ heroku run rake db:setup
Running `rake db:setup` attached to terminal... up, run.1

d36q1tfb51f169 already exists
sh: psql: not found

再次在最后一行出现错误。

然后，如果我检查heroku的日志，我会得到以下内容（我认为因为它没有运行迁移）：

提前感谢您的帮助

Answer 1

最好的猜测是，您有未运行的优秀迁移。

试试heroku run rake db:migrate。这应该清除relations do not exist错误。

其余的，他们是警告。您可以忽略它们，但是您看到了这一点，因为项目中的vendor/plugins文件夹可能非空，而当Rails 4到达时，这将被弃用。

Answer 2

为了解决这个问题，我只是从它工作的时候经过我的git，并逐步添加了新的功能并且能够找到问题

Answer 3

对于未来的浏览器，this question为我解答了这个问题。只需将其添加到Rakefile的底部：

Rake::Task["db:structure:dump"].clear unless Rails.env.development?

Rails Postgres部署到heroku问题
