Ruby on Rails : Where i can get error log?
提问by AviSingh Rajput
I am new in ruby on rails. When ever something is wrong I got this error:
我是 ruby on rails 的新手。每当出现问题时，我都会收到此错误：
Template is missing
Missing template errors/error_404 with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee]}.
Searched in: * "C:/Users/Avi/Documents/Aptana Studio 3 Workspace/social/app/views" * "C:/RubyonRails/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/devise-2.2.4/app/views"
But the problem is something syntax error or programming error.
但问题是语法错误或编程错误。
Can I get a error log, something like in cakephp?
我可以得到一个错误日志，比如 cakephp 吗？

like @thomas-klemm already wrote, you can tail the files in log. those logs are named after the environment you are running (development locally, production for live etc).
就像@thomas-klemm 已经写过的那样，你可以在日志中拖尾文件。这些日志以您正在运行的环境命名（本地开发、实时生产等）。
if you want to get all the output you can do a tail log/*
如果你想获得所有的输出，你可以做一个 tail log/*
from what i know, cakephp has a really nice application monitoring and administration backend. if you want something similar for rails, you can use better_errors: https://github.com/charliesome/better_errors
据我所知，cakephp 有一个非常好的应用程序监控和管理后端。如果你想要类似 rails 的东西，你可以使用 better_errors：https: //github.com/charliesome/better_errors

Open your rails application. You will find a directory named log. Open it then you will find a log file named development. It is the file where are the errors are logged.
打开您的 Rails 应用程序。您将找到一个名为log的目录。打开它，你会发现一个名为development的日志文件。它是记录错误的文件。
