ruby-on-rails-3.2

问题 I'm following along with the Ruby on Rails Tutorial. Things are working pretty well, but I noticed that Guard only runs after I save some files (view or controller files), but doesn't run when I save others (routes or spec files).

When I looked at the console window running Guard/Spork, I noticed an error after I saved the non-running tests: Exception encountered: #<LoadError: no such file to load -- /Users/Tyler/Development

问题 I was wondering what rails offers to obfuscate e-mail addresses to protect it from crawlers, spambots and mail harvesters, gathering addresses to send spam. May be I used wrong keywords, but wasn’t really able to find a gem. I found a statistic comparing different methods to mask the mail address: http://techblog.tilllate.com/2008/07/20/ten-methods-to-obfuscate-e-mail-addresses-compared/ I wrote a snippet that combines the top two methods. The snipped isn’t mature yet, but I like to share it

问题 Working on a rails app in French, however whenever i include an accent on the flash messages it breaks the site. For example format.html {redirect_to @message.annonce, notice:"Votre message a été envoyé"} format.html {redirect_to @message.annonce, notice:"Votre email n'a pas pu être envoyer à cause d'une erreur."} my config/application.rb looks like this config.i18n.default_locale = :fr config.encoding = "utf-8" How does one do about this? 回答1: You should add # encoding: UTF-8 as the first

问题 I am currently using Rails 3.2.5 with the latest devise gem. Currently users can access their profile page at... example.com/users/john-doe I want to remove the users portion of the url, so the url would be example.com/john-doe . Is this possible with devise? Right now in my routes file I have the following... devise_for :users, :controllers => {:omniauth_callbacks => 'omniauth_callbacks'} 回答1: Just add a route for it. You will probably want it to be the last one in the routes file. Something
