Heroku 500內部服務器錯誤

我正在開發一個Ruby on Rails應用程序並試圖用Heroku進行部署，但是我有一些我無法解決的錯誤。我已經瀏覽了Heroku日誌，可以看到詳細信息，但我不知道什麼是錯的。這個問題在我看來是來自我的_header.html.erb文件，但我不知道爲什麼。任何幫助，將不勝感激。以下是日誌（道歉長度）：Heroku 500內部服務器錯誤

這是我的頭：

<header> 
    <%= link_to logo, root_path %> 
    <nav class="round"> 
    <ul> 
     <li><%= link_to "Home", root_path %></li> 
     <% if signed_in? %> 
     <li><%= link_to "Profile", current_user %></li> 
      <li><%= link_to "Settings", edit_user_path(current_user) %></li> 
       <% if current_user.admin? %> 
        <li><%= link_to "Users", users_path%></li> 
       <% end%> 
     <li><%= link_to "Sign out", signout_path, :method => :delete %></li> 
     <% else %> 
     <li><%= link_to "Sign in", signin_path %></li> 
     <% end %> 
    </ul> 
    </nav> 
</header>

，這些都是2種方法在日誌中提到的會議助手：

def user_from_remember_token 
     User.authenticate_with_salt(*remember_token) 
    end 

def current_user 
    @current_user ||= user_from_remember_token 
    end

我想你的數據庫heroku是不同步的。嘗試：

heroku run rake db:version

如果它從本地數據庫則有所不同：

heroku run rake db:migrate

謝謝，我是個白癡。 – Hugs

你不是。通常，當我們太專注於某些事情時，我們錯過了簡單的猜測:) – lucapette

對於感興趣的各方，「heroku rake」已被棄用。它不應該是「heroku run rake」，而是用於在服務器上運行rake命令。 – csalvato
