Heroku Postgres错误：PGError：错误：关系“组织”不存在（ActiveRecord :: StatementInvalid）

问题描述

  SELECT a.attname，format_type（a.atttypid，a.atttypmod），d.adsrc，a.attnotnull 
 FROM pg_attribute a LEFT JOIN pg_attrdef d 
 ON a.attrelid = d.adrelid AND a.attnum = d.adnum 
 WHERE a.attrelid ='organizations'：regclass 
 AND a.attnum> 0 AND NOT a.attisdropped 
 ORDER BY a.attnum 
  

有人有什么想法吗？这对我来说是第一次，尤其是因为我一直在Heroku上使用其他应用程序一年的时间，并没有看到类似的东西。当然，所有的东西都可以在本地SQLite上运行。

解决方案

我遇到了同样的问题。为了解决这个问题，重置数据库更容易。

• heroku rake db：reset（'heroku run rake db：reset'if you'
  
• heroku rake db：migrate（'heroku run rake db：migrate'如果您使用雪松）

然后，迁移成功完成了我的情况：）

虽然这是一个很好的解决方案，但不要这样做在生产上。它会删除数据库中的所有记录

I'm having a problem deploying my Rails app to Heroku, where this error is thrown when trying to access the app:

SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
FROM pg_attribute a LEFT JOIN pg_attrdef d
  ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"organizations"'::regclass
  AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum

Anybody have any ideas? This is a first for me, especially because I've been working with Heroku for a year on other apps, and haven't see anything like this. Of course, everything works on local SQLite.

解决方案

I had the same problem. To solve it, resetting the database is more easier.

• heroku rake db:reset ('heroku run rake db:reset' if you're on cedar)
• heroku rake db:migrate ('heroku run rake db:migrate' if you're on cedar)

Then, migration was done successfully for my case :)

While this is a good solution in this context, don't do it on production. It will delete all the records from your database
