Heroku + Sinatra + Datamapper(Heroku + Sinatra + Datamapper)

Heroku + Sinatra + Datamapper(Heroku + Sinatra + Datamapper)

我的问题部署我的Sinatra + DataMapper应用程序到Heroku。 该应用程序在本地工作，但部署它爆炸。

这是错误：

带有显式：串行选项的整数ID已弃用，请使用串行（./hello.rb:15）/home/slugs/339253_c667ceb_65a5-45e31e8c-0236-4d03-96ec-a59bdabdf788/mnt/.gems/gems/dm-migrations- 1.0.2 / lib / dm-migrations / adapters / dm-postgres-adapter.rb：84：在`property_schema_hash'：范围错误值（ArgumentError）

代码如下所示：

Class Post include DataMapper::Resource property :id, Integer, :serial => true property :title, String end Post.auto_migrate! first_post = Post.new first_post.title = "First!" first_post.save

这是一个宝石版本问题，还是我错过了什么？

Im getting issues deploying my Sinatra + DataMapper app to Heroku. The app works locally but deploying it blows up.

Here's the error:

Integer id with explicit :serial option is deprecated, use Serial instead (./hello.rb:15) /home/slugs/339253_c667ceb_65a5-45e31e8c-0236-4d03-96ec-a59bdabdf788/mnt/.gems/gems/dm-migrations-1.0.2/lib/dm-migrations/adapters/dm-postgres-adapter.rb:84:in `property_schema_hash': bad value for range (ArgumentError)

The code looks like this:

Class Post include DataMapper::Resource property :id, Integer, :serial => true property :title, String end Post.auto_migrate! first_post = Post.new first_post.title = "First!" first_post.save

Is this a gem versioning issue, or am I missing something?

最满意答案

看起来你在本地使用了另一个版本的datamapper。

使用： gem list --local检查您的本地版本

建议使用Serial而不是Integer。

You use another version of datamapper locally it seems.

Check your local version with: gem list --local

Also use Serial instead of Integer as proposed.
