这种情况一直持续下去

我写了这三行代码来获取我所需要的两个不同对象的操作中的categories/category

@categories = Category.all
@category = Category.first
@category = Category.where(:search_index => params[:s_i], :keyword => params[:key]).first if params[:s_i]

我甚至没有在development.rb中启用缓存

config.action_controller.perform_caching = false

奇怪的是，它在heroku上我的登台服务器上运行良好

我尝试了以下命令，但似乎没有任何帮助

Rails.cache.clear

rake tmp:cache:clear

如果有人帮助我理解出了什么问题，我会非常感激

我在

ubuntu14.04

上使用

rails4.2.5

和

Ruby 2.2.3

，看起来你在一遍又一遍地渲染

welcome/store.html.erb

。查看呈现该模板的部分代码。哦，您看到的

缓存与rails缓存无关。这是activerecord在同一请求中执行相同sql查询的方法。@jvnill对此表示感谢。你知道为什么这个查询会被重复吗？通常，当一个无限循环发生时，你会在自己内部调用模板。尝试对整个文件进行注释，然后慢慢取消对部分文件的注释。很抱歉，我最初是这样做的。
