我有一个Rails应用程序,我试图在生产环境中测试.我跑了RAILS_ENV=production rake assets:precompile,它在/ public/assets中生成了我的所有资产.问题是,当我启动我的应用程序时,RAILS_ENV=production rails s thin我得到:
ActionController::RoutingError (No route matches [GET] "/assets/application-eff78fd67423795a7be3aa21512f0bd2.css"):
这个文件确实存在于/public/assets/application-eff78fd67423795a7be3aa21512f0bd2.css.
有什么想法为什么我得到这个RoutingError？
我刚刚阅读了一篇博客文章,并注意到作者tap在一个片段中使用了类似于:
user = User.new.tap do |u|
u.username = "foobar"
u.save!
end
我的问题是使用的好处或优势究竟是什么tap？我不能这样做:
user = User.new
user.username = "foobar"
user.save!
或者更好的是:
user = User.create! username: "foobar"
鉴于我Personable在我的Rails 4应用程序中有一个问题有一个full_name方法,我将如何使用RSpec进行测试？
关注/ personable.rb
module Personable
extend ActiveSupport::Concern
def full_name
"#{first_name} #{last_name}"
end
end
我需要调整一些与iPhone状态栏高度相关的元素.我知道状态栏通常是20点高,但当它处于网络共享模式时不是这种情况.它被加倍到40.确定它的高度的正确方法是什么？我试过了
[[UIApplication sharedApplication] statusBarFrame]
但它给了我20 x 480的景观,这是正确的,但它给了我320 x 40的肖像.它为什么不给我相反的(40 x 320)？
我试图bundle在OSX 10.9上运行我的Rails项目.pg使用此错误进入gem 时失败:

validates :text,
presence: { :unless => Proc.new{ |a| a.question.is_a? Question::Document } }
这给了我警告

如何防止发生此警告(不重命名我的课程)？
我正在创建一个红宝石宝石,我注意到(据我所知)似乎没有宝石的命名约定.例如,我见过两个:
gem 'foo-bar'
gem 'foo_bar'
红宝石的命名是否有某种明确的指导/惯例？
ruby rubygems ruby-on-rails ruby-on-rails-3 ruby-on-rails-3.1
我有一个处理基于断码的用户密码的编辑定制控制器在这里.
用户模型
attr_accessible :password, :password_confirmation, :username, :login
...
devise :database_authenticatable,
:lockable,
:registerable,
:recoverable,
:rememberable,
:trackable
PasswordsController
expose(:user) { current_user }
def update
if user.update_with_password(params[:user])
sign_in(user, :bypass => true)
flash[:notice] = "success"
else
render :edit
end
end
我的编辑密码表单位于此处.
问题在于,无论我输入(或不输入该内容)到编辑密码表单中,都会显示"成功"闪存方法.
我正在尝试调试运行时我的应用程序试图连接到我的数据库的原因rake assets:precompile --trace.
我可能在堆栈跟踪中遗漏了一些东西......有人看到相关的线路吗？

我可以通过做某些事情来访问元素,jsonResponse['version']但我无法做到jsonResponse.version.为什么是这样？
