先安裝 request-log-analyzer gem，建議把 log 檔抓到自己電腦來做分析。

gem i request-log-analyzer

分析某一個 log 檔

request-log-analyzer log/production.log --output HTML --file tmp/log_report.html

指定多個 log 檔

Flash

# supports only notice and alert by default
# the rest has to go into flash hash
redirect_to :index, notice: "success"
redirect_to :new, notice: "errors"
redirect_to :new, flash: { success: "yeah" }
flash[:info] = "updated"

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

API workthough

Open a browser

# start an instance of firefox with selenium-webdriver
driver = Selenium::WebDriver.for :firefox
# :chrome -> chrome
# :ie     -> iexplore

Go to a specified URL

Some smart people who didn’t want to teach users how to code in HTML invented Textile markup language

Someone more lazy invented MarkDown syntax which is much easier to learn. MarkDown is really nice for small content management systems, blogging engines etc.

For instance, to mark text as bold, you write the “bold text” like “bold text”. Other rules can be found in the syntax page.

However, when you have a MS Word document with several pages of bolds, italics and lists, you don’t really want to re-code all the markup.

Welcome to #rubyonrails

Please behave in a polite, considerate and inclusive manner in the channel at all times. People volunteer their time in the channel to help people like you with your Rails problems and some respect (in both directions) will go an extremely long way.

These rules are in place so that you can get the quickest and best support from #rubyonrails.

Rule #0: Show rather than tell. Explaining your problem with code, stacktraces or errors is always preferred to explaining it with just text. Show us what's happening, rather than telling us.

Do your research before hand. Your question may be answerable with a quick Google search or by simply experimenting. If you're using a method in Rails, look it up in the API Docs or in the Official Guides.
If you've tried Googling, explain what terms you've tried to use so people can better help you.
