关于 secret_token？

jhunter — Tue, 01 Jul 2014 21:38:45 +0800

我的 ruby 版本是 2.0.0，rails 的版本是 4.1.1，然后问题是 rails new 项目的时候不会自动产生 secret_token.rb 文件，这是为什么呢？

测试失败，路由不知道哪里有问题

user_pages_spec.rb 的源程序如下：

 1 require 'spec_helper'
 2 
 3 describe "User pages" do
 4 
 5     subject { page }
 6 
 7     describe "profile page" do
 8         let(:user) { FactoryGirl.create(:user) }
 9         before { visit user_path(user) }
10 
11         it { should have_content(user.name) }
12         it { should have_title(user.name) }
13     end
14 
15     describe "signup page" do
16         before { visit signup_path }
17 
18         it { should have_content('Sign up') }
19         it { should have_title(full_title('Sign up')) }
20     end
21 end

错误如下：

  1) User pages profile page 
     Failure/Error: before { visit user_path(user) }
     ActionController::RoutingError:
       uninitialized constant UsersController

不知道哪里出了问题？请大家帮帮忙

关于 git 切换问题？

问题是我首先 git checkout -b new，这个时候会切换到 new 这个分支，然后在分支上代码改动过了，不做任何提交，这个时候我 git checkout master，切换到主分支，为什么主分支的代码也变了，怎么样切换到不会变化的主分支？

卡住了，Rails Tutorial Chapter 遇到的问题

jhunter — Thu, 29 May 2014 18:11:45 +0800

完全卡住了，看书加了 gem 'bootstrap-sass'，并在 config/application.rb 里添加

config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)，到这一步还没有出错，然后再按照书上操作向应用程序中添加自定义的 CSS，首先要创建一个 CSS 文件：app/assets/stylesheets/custom.css.scss，然后在 custom.css.scss 文件中写入下面的代码

@import "bootstrap"。再次运行的时候就报错，显示的错误是：

Showing /Users/33kkk/ruby/rails_projects/sample_app/app/views/layouts/application.html.erb where line #5 raised:

undefined method `environment' for nil:NilClass (in /Users/33kkk/ruby/rails_projects/sample_app/app/assets/stylesheets/custom.css.scss) Extracted source (around line #5):

第五行被红色标注，不知道是为什么，能不能帮忙解决一下一直停在这里
