Heroku rake db：migrate aborted

Question

我有一个应用程序在开发中工作正常，但是当我将它推到heroku并试图运行“heroku run rake db：migrate”时，耙子中止并显示以下消息：

rake aborted! 
PG::Error: ERROR: relation "submissions" does not exist 
LINE 4:    WHERE a.attrelid = '"submissions"'::regclass 
             ^
:    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 = '"submissions"'::regclass 
       AND a.attnum > 0 AND NOT a.attisdropped 
      ORDER BY a.attnum 

我不确定从哪里开始测试。我在模式中找不到问题。耙db：安装也不起作用。这是我的模式：

    end 

end 

任何建议我应该在哪里寻找问题？我应该寻找什么？

我见过很多类似的问题，但似乎没有明确的答案来寻找。

UPDATE： 这里是我的ActiveAdmin初始化：

ActiveAdmin.setup do |config| 
    config.site_title = "Cif4" 
    config.authentication_method = :authenticate_admin_user! 
    config.current_user_method = :current_admin_user 
    config.logout_link_path = :destroy_admin_user_session_path 
    config.batch_actions = true 
end 

Answer 1

有此遭遇的很多人近来由于Heroku的定价和数据库大小的变化。

如果您的应用有超过10,000行并且您的计划不够高，写入失败。

我们回答这个是我们必须：

1）选择higehr计划，将使40万行，而不是刚开始只要10000

2）重新指向我们的应用程序到新的数据库。我没有参与，但显然这一步是认为已经完成，但实际上并没有，所以如果有必要的话搜索。
