ruby-on-rails - Heroku 500 内部服务器错误

标签 ruby-on-rails heroku

我正在开发 Ruby on Rails 应用程序并尝试使用 Heroku 部署它，但是我遇到了一些无法解决的错误。我已经查看了 Heroku 日志，可以看到详细信息，但我不知道出了什么问题。在我看来，问题来 self 的 _header.html.erb 文件，但我不知道为什么。任何帮助将不胜感激。以下是日志(对长度表示歉意):

这是我的标题:

<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>

这些是日志中提到的 session 帮助程序中的 2 个方法:

def user_from_remember_token
      User.authenticate_with_salt(*remember_token)
    end

def current_user
    @current_user ||= user_from_remember_token
  end

最佳答案

我猜你的heroku上的数据库不同步。尝试:

heroku run rake db:version

如果它与您的本地数据库不同，则:

heroku run rake db:migrate
