我已经安装了Rails并尝试按照说明设置自定义错误处理，但是我仍然收到gem创建的标准500错误消息：

500内部服务器错误

如果您是本网站的管理员请阅读此web应用程序的日志文件和/或 web服务器的日志文件，以查找出了什么问题

下面是我添加到

config/application.rb

的内容：

class Application < Rails::Application
  config.exception_handler = {
      dev: true,
      layouts: {
        '500' => 'exception'
      }
  }
end

<!DOCTYPE html>
<html>
  <head>
    <title><%= "Error - #{@exception.status} Error" %></title>
  </head>

  <body>

    <div class="container">
      <%= yield %>
    </div>

  </body>
</html>

并使用以下命令生成默认异常视图：

rails generate exception\u handler:views

<div class="error">
    <% if /^(5[0-9]{2})$/ =~ @exception.status.to_s %>

        <!--Message -->
        <%= content_tag :div, class: "message" do %>
            <%= content_tag :div, class: "title" do %>
                <span><%= "#{@exception.status} Error - #{details[:name]}" %></span>
                <%= link_to image_tag("exception_handler/close.png"), main_app.root_url, title: "Close (Go back home)", class: "close" %>
            <% end %>

            <%= content_tag :div, class: "details" do %>
                <%= image_tag "exception_handler/alert.png", title: "#{@exception.status} Error" %>
                <div class="status"><%= @exception.status %> Error</div>
            <% end %>

            <%= content_tag :div, class: "info" do %>
                <span><%= details[:description] %></span>
                <div class="notification">
                    <%= link_to image_tag("exception_handler/home.png", title: "Go Back Home"), main_app.root_url, class: "home" %>
                    <div class="version">v<%= Rails.version %></div>
                    <strong>Our developers have been notified - we're working on it!</strong>
                </div>
            <% end %>
            
        <% end %>

    <% else %>

        <%= content_tag :div, details[:description], class: "message" %>
            
    <% end %>
</div>


错误

我们的开发者已经得到通知-我们正在努力

我尝试重新启动rails服务器，只是为了确保更改生效，但仍然不起作用。我错过了什么？
在版本异常处理程序0.8.0.0的config/application.rb中

config.exception_handler = { dev: nil, # allows you to turn ExceptionHandler "on" in development db:nil, # allocates a "table name" into which exceptions are saved (defaults to nil) email: "", # sends exception emails to a listed email (string // "you@email.com") # Custom Exceptions custom_exceptions: { #'ActionController::RoutingError' => :not_found # => example }, # On default 5xx error page, social media links included social: { facebook: nil, # Facebook page name twitter: nil, # Twitter handle youtube: nil, # Youtube channel name / ID linkedin: nil, # LinkedIn name fusion: nil # FL Fusion handle }, # This is an entirely NEW structure for the "layouts" area # You're able to define layouts, notifications etc ↴ # All keys interpolated as strings, so you can use symbols, strings or integers where necessary exceptions: { :all => { layout: "exception", # define layout notification: true # (false by default) # action: ____, (this is general) # background: (can define custom background for exceptions layout if required) }, 404 => { layout: "exception", # define layout notification: true # (false by default) # action: ____, (this is general) # background: (can define custom background for exceptions layout if required) }, 500 => { layout: "exception", # define layout notification: true # (false by default) # action: ____, (this is general) # background: (can define custom background for exceptions layout if required) } # This is the old structure # Still works but will be deprecated in future versions # 501 => "exception", # 502 => "exception", # 503 => "exception", # 504 => "exception", # 505 => "exception", # 507 => "exception", # 510 => "exception" } }

您是否查看了日志文件错误是什么？可能是这个gem无法处理的错误。您的
config/development.rb
中确实有
配置。请考虑所有请求\u local=true
，对吗？PS：我假设您正在dev env上测试此功能。@AlexandreAngelim yes@slowjack2k似乎正在尝试使用我的默认布局
application.html.erb
，而不是
exception.html.erb
：

应将

更改为

（键500-是整数而不是字符串）
