Rails:重定向到原始404页面时错误丢失模板

Luc*_*cas 1 ruby-on-rails ruby-on-rails-3

这是我的问题.

在我的控制器中,我检查URL中给出的参数是否是有效用户,如果不是我希望将访问者重定向到"经典"404页面.这是我的控制器:

def home
  @user = User.find_by_domain(params[:domain])

  if !@user.nil?
    respond_to do |format|
      format.html # home.html.erb
    end
    else
      render(:file => "#{RAILS_ROOT}/public/404.html", :status => 404, :layout => false)
    end
end

然而,当@user就是nil我得到以下错误:

Template is missing Missing template D:/Project/public/404.html with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} in view paths

我没有修改Rails生成的404页面:

<!DOCTYPE html>
<html>
<head>
  <title>The page you were looking for doesn't exist (404)</title>
  <style type="text/css">
    body { background-color: #fff; color: #666; text-align: center; font-family: arial, sans-serif; }
    div.dialog {
      width: 25em;
      padding: 0 4em;
      margin: 4em auto 0 auto;
      border: 1px solid #ccc;
      border-right-color: #999;
      border-bottom-color: #999;
    }
    h1 { font-size: 100%; color: #f00; line-height: 1.5em; }
  </style>
</head>

<body>
  <!-- This file lives in public/404.html -->
  <div class="dialog">
    <h1>The page you were looking for doesn't exist.</h1>
    <p>You may have mistyped the address or the page may have moved.</p>
  </div>
</body>
</html>

试试这个,可能对你有帮助,谢谢

if !@user.nil?
 respond_to do |format|
   format.html # home.html.erb
 end
else
  raise ActiveRecord::RecordNotFound
end

我是rails应用程序,这是我处理404的方式,在我的application_controller.rb中,我的代码如下:

unless Rails.application.config.consider_all_requests_local
rescue_from Exception, :with => :render_error
rescue_from ActiveRecord::RecordNotFound, :with => :render_not_found
rescue_from ActionController::UnknownController, :with => :render_not_found
rescue_from ActionController::UnknownAction, :with => :render_not_found
end

private
def render_not_found(exception)
  render :template =>"/error/404", :status => 404
end

def render_error(exception)
  render :template =>"/error/500", :status => 500
end

在config/environments/development.rb中确保:

config.consider_all_requests_local = true
