我试图使用Chartkick生成显示在rails主动管理仪表板上的图形.这是我正在使用的教程:http://www.patrickedelman.com/simple-charting-for-activeadmin/

但是,图表没有显示,而是显示"正在加载..."

我已经安装了javascript_include_tag"//www.google.com/jsapi","chartkick"和gem chartkick,但它仍然无效.

请帮忙!谢谢.

我使用 twitter APIfetchTimelineForUser:(NSString *)username来获取推文时间线。该对象中用户头像的大小是正常的。但我需要更大尺寸的图像。

我怎样才能做到这一点？

顺便说一句，我不想​​从 Twitter 获取用户对象。

谢谢。

我正在使用ActiveAdmin,我有一个文件这样做:

ActiveAdmin.register角色做点什么---结束

但是,我的服务器给了我这个错误:
