我无法获得rake db:migrate在Heroku上的rails 4.0.1 app上运行。
我猜我没有正确配置postgres ...但是阅读heroku上的文档并没有真正帮助,我不知道该怎么做。我对heroku或postgres不太了解。
非常感谢任何帮助或资源。如果还有其他我可以发布的内容,请告诉我。
(另外,我正在使用设计,如果重要的话)
当我运行heroku run rake db:migrate
时,我明白了:
Running `rake db:migrate` attached to terminal... up, run.5077
PG::UndefinedTable: ERROR: relation "users" does not exist
LINE 5: WHERE a.attrelid = '"users"'::regclass
^
: SELECT a.attname, format_type(a.atttypid, a.atttypmod),
pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"users"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
rake aborted!

当我运行heroku run rake db:setup
时,我明白了:
FATAL: permission denied for database "postgres"

我会先尝试
heroku restart
heroku rake db:migrate
如果这不起作用,请尝试。
heroku pg:reset DATABASE_URL #Literally type in heroku pg:reset DATABASE_URL
heroku rake db:migrate

我应该更仔细地阅读堆栈跟踪。我的factories.rb正在创建用户对象作为其他工厂的属性。将它们包裹在一个块中固定它:

运行
heroku pg:reset DATABASE_URL
你已经完成了。

Jason的回答可能会解决您的问题,但我想扩展您遇到错误的原因以及解决方法。
你不能在Heroku上运行“rake db:setup”,因为它会尝试创建一个数据库,你的数据库已经存在于Heroku上
在您的database.yml中,您应该从环境变量中读取数据库URL,如:
制作:<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="app"/>
我认为您收到第二个错误,因为您的迁移中存在一些版本错误,从一开始就运行它们应该修复它:
url: <%= ENV["DATABASE_URL"] %>

删除并重新创建数据库
heroku pg:reset DATABASE
