ruby-on-rails – Heroku上的Authlogic抛出错误

这是我在我的production.log中得到的：

ActionView::TemplateError (undefined method `password' for #<User:0x2b0ddb58cdc0>) on line #11 of app/views/users/new.html.erb:
8:         </p>
9:         <p>
10:           <%= f.label :password,"Password:" %><br />
11:           <%= f.password_field :password %>
12:         </p>
13:         <p>
14:           <%= f.label :password_confirmation,"Password again:" %><br />

当我尝试：

$heroku rake db:reset RAILS_ENV=production

我明白了：

yeqynzfiku already exists
(in /disk1/home/slugs/109616_e6df6f2_8837/mnt)
Couldn't drop yeqynzfiku : #<ActiveRecord::StatementInvalid: PGError: ERROR:  must be owner of database yeqynzfiku
: DROP DATABASE IF EXISTS "yeqynzfiku">

我不知道这意味着什么.我也试过了

$heroku rake db:reset
$heroku rake db:migrate RAILS_ENV=production
$heroku rake db:migrate
$heroku rake gems:install (for what it's worth)

在开发和生产模式下,一切都在本地运行良好.我的应用程序中有一个.gems文件,当我第一次推送到Heroku时,似乎安装了AuthLogic和Paperclip就好了.

难住了.谢谢.
