问题描述

一段时间以来，我一直面临一个奇怪的问题，其中ActiveRecord查询未在终端或Rails控制台中记录(使用 ActiveRecord :: Base.logger = Logger.new(STDOUT)).

I have been facing a weird problem for some time, wherein ActiveRecord queries are not getting logged in the terminal, or in the Rails console (using ActiveRecord::Base.logger = Logger.new(STDOUT)).

这是我得到的例外:

Could not log "sql.active_record" event. NameError: undefined
local variable or method `s'
for # ActiveSupport::Notifications::Event:0x007f9ae02a60c0.

我尝试了一些操作，包括重新安装Rails，但无济于事.

I tried out a few things, including reinstalling Rails, but to no avail.

除了想知道为什么会发生这种情况之外，我无法检查由此对数据库触发的实际SQL查询.

Apart from wondering why this is happening, I’m unable to check the actual SQL queries fired against the database as a result.

`推荐答案`

此问题是由于在instrumenter.rb文件中插入了流浪(偶然)引起的.删除角色可以帮助我解决问题.我不确定为什么重新安装滑轨对我没有帮助.

This problem was due to a stray (and accidental) 's' being inserted in the instrumenter.rb file. Removing the character helped me fix the problem. I'm not sure about why reinstalling rails did not help me though.
