rails_admin不显示视图/编辑控件

Question

我在生产服务器上使用Ruby 1.9.3p194和rails_admin 0.3.0有一个遗留的Rails应用3.2.14。工作正常。

我将这个传统的Rails应用程序迁移到新服务器并让应用程序启动，到目前为止很少有问题。我遇到的主要问题之一是使用rails_admin。当我以管理员用户身份登录时，我可以看到所有模型/表格，但在选择表格时，我会看到一个记录列表，但没有用于编辑/查看每条记录的控件。

添加新记录不是问题，rails_admin行为正常。但我无法查看或编辑特定记录。

它可以在我们的生产服务器上运行，但是当我把它推到这个新服务器时（这几乎是一个相同的环境，而不是在64位Ubuntu和生产中的32位Ubuntu）我看不到任何控件编辑记录。

我只是不确定它为何在生产中运行，但在部署到第二台服务器时出现此问题。

这是我的Gemfile

Answer 1

您需要从gemfile中删除gem 'font-awesome-rails', '~> 4.1.0.0'并运行bundle install。

实际上rails_admin使用Bootstrap 2和FontAwesome 3.但是你要从gemfile安装FontAwesome 4。它导致宝石版本的冲突。 RailsAdmin使用旧式语法（例如＆＃39; icon icon-pencil＆＃39;）而不是新式（例如＆＃39; fa fa-pencil＆＃39;）。因此，图标没有显示出来。

您可以在没有FontAwesome 4的情况下生活，只需删除它即可。

杰夫也有same problem。
