我试着让它在玉模板中工作:
HTML:
<li><i class="icon-comment"></i> 5</li>
玉:
li:i.icon-comment 5
ofcource 5现在嵌套在i标签下,而不是li.有什么办法吗？
嗨,我正在尝试使用ec2的橡胶宝石,但有一些问题通过快速启动部分.出于某种原因,橡胶下的雾没有找到关键对.这是详细信息:
在irb中(这里的路径是我的rubber.yml key_file属性 - gsg-keypair是我没有pem扩展名的私钥,它的公钥在同一个dir中):
1.9.3p125 :010 > File.open("#{Dir[(File.expand_path('~') rescue '/root') + '/.ec2/*'].first}")
=> #<File:/home/charlie/.ec2/gsg-keypair>
但每次我运行:cap rubber:create_staging接受所有默认值我得到这个:
/home/charlie/.rvm/gems/ruby-1.9.3-p125@bag/gems/excon-0.15.4/lib/excon/connection.rb:276:in `request_kernel': The key pair 'gsg-keypair' does not exist (Fog::Compute::AWS::NotFound)

知道为什么会这样吗？
谢谢查理
我有一个rspec模拟对象,一个值被赋值为属性.我很难在我的rspec测试中满足这种期望.只是想知道sytax是什么？代码:
def create
@new_campaign = AdCampaign.new(params[:new_campaign])
@new_campaign.creationDate = "#{Time.now.year}/#{Time.now.mon}/#{Time.now.day}"
if @new_campaign.save
flash[:status] = "Success"
else
flash[:status] = "Failed"
end end
考试
it "should able to create new campaign when form is submitted" do
campaign_model = mock_model(AdCampaign)
AdCampaign.should_receive(:new).with(params[:new_campaign]).and_return(campaign_model)
campaign_model.should_receive(:creationDate).with("#{Time.now.year}/#{Time.now.mon}/#{Time.now.day}")campaign_model.should_receive(:save).and_return(true)
post :create
flash[:status].should == 'Success'
response.should render_template('create') end
问题是我收到此错误:
Spec::Mocks::MockExpectationError in 'CampaignController new campaigns should able to create new campaign when form is submitted' Mock "AdCampaign_1002" received unexpected message :creationDate= with ("2010/5/7")
那么我如何设置对象属性赋值的期望？
谢谢
我正在使用bootstrap作为我正在编写的chrome扩展.当作为内容脚本导入时,css似乎与我正在查看的很多站点冲突(即使在谷歌搜索结果页面中).
想知道我是否可以做任何事情来限制我使用内容脚本注入的dom元素？
我has_one在序列化程序中有一段关系,但设置root: :some_other_root似乎没有任何区别.我在文档中看到他们只使用了不同的root名称has_many.所以问题是是否可以使用不同的根名称has_one？
给定:
class UserSerializer < ActiveModel::Serializer
attributes :id
has_one :address, root: :primary_address
end
收益:
{"user":{"id": 12, "address":{"id":5,"company_name":"widgets co"}}}
预期:
{"user":{"id": 12, "primary_address":{"id":5,"company_name":"widgets co"}}}
