有没有办法将带有敲除的src属性数据绑定iframe到我的modelView中的项目？这个...

<iframe data-bind="src: BioLink" width="100%" height="300">
<p>Your browser does not support iframes.</p>
</iframe>

......没有做到这一点.

这个查询

SELECT
FirstName, LastName, NCAAStats.AccountId, College_Translator.school_name, StatTypeId, COUNT(*) AS 'Count'
FROM NCAAstats
INNER JOIN College_Translator
ON College_Translator.AccountID = NCAAstats.AccountId
GROUP BY FirstName, LastName, NCAAStats.AccountId, College_Translator.school_name, CalendarYear, StatTypeId
HAVING COUNT(*) >1
ORDER BY 'Count' DESC

选择我想一个记录集ISValid位0.

这些记录是由于输入错误而在我的数据库中出现两次的记录.

我正在寻找类似的东西:

UPDATE NCAAstats
SET IsValid = 0
WHERE (my select statement)

这是在MS SQL SERVER 2008上

谢谢!

我正在尝试使用Passenger来托管我的rails应用程序,但正如本期所述,在rails 3.2.1中,日志记录有点不可思议.有人已经通过修复发布了一个提交(已被拉入主分支).如何告诉我的应用程序使用主分支而不是特定版本的rails gem？另外,是否有一种方法可以指定提交,以防更改稍后被另一次拉取覆盖？

像(在我的Gemfile中):

gem 'rails', git => 'git://github.com/rails/rails.git:<commit hash>'

我创建了一个.ics包含多个事件的文件,我想将其作为新日历添加到Outlook中(因此我可以轻松删除它).如果我双击该.ics文件,事件将添加到我当前的日历(而不是新的日历).我找不到要添加或导入日历的菜单项.

我想我错过了一些明显的东西.有任何想法吗？

Outlook 2011 for Mac

谢谢

我想在Storyboard中设置递归表视图.通过递归,我的意思是你单击TableView中的一个项目,它会加载一个新的表视图实例,只显示新的数据.这样,我可以重用Table View Controller中包含的Table View Cells和逻辑.我的数据在数组数组的数组中......

我能找到的唯一工作就是设置ua导航控制器,将我的表视图控制器作为根视图控制器,然后使用Push推送另一个Table View Controller实例.然后,第二个表视图控制器推送原始的表视图控制器,我有我的递归表视图控制器.我只是想消除表视图控制器的重复(即使它只有一次).

谢谢

当我尝试运行任何cap命令时,我得到一个"没有这样的文件加载 - 部署"错误.

我ActiveSupport::HashWithIndifferentAccess尝试更新嵌入表单时遇到错误.

这是最简单的例子:

形成:

<h1>PlayersToTeams#edit</h1>
<%= form_for @players_to_teams do |field| %>
    <%= field.fields_for @players_to_teams.player do |f| %>
        <%= f.label :IsActive %>
        <%= f.text_field :IsActive %>
    <% end %>
    <%= field.label :BT %>
    <%= field.text_field :BT %>
    <br/>
    <%= field.submit "Save", class: 'btn btn-primary' %>
<% end %>

楷模:

class PlayersToTeam < ActiveRecord::Base
  belongs_to :player
  belongs_to :team

  accepts_nested_attributes_for :player
end

class Player < ActiveRecord::Base
  has_many :players_to_teams
  has_many :teams, through: :players_to_teams
end

控制器:

class PlayersToTeamsController < ApplicationController
  def edit
    @players_to_teams=PlayersToTeam.find(params[:id])
  end …

我有一个佣金任务

task :post_hit, [:host, :title, :description, :model, :num_assignments, :reward, :lifetime, :qualifications, :p, :opts] => :environment do |t, args|

:p 需要是一个哈希,但如果我尝试:

rake turkee:post_hit["http://www.staging.collegesportsbluebook.com","LS Info","Fill In Player First Name","MechanicalTurk",100,0.01,2,{},{id: 5},{}]

它错误地说id:无法解析(空间似乎做了一些事情).

如果我试过:

rake turkee:post_hit["http://www.staging.collegesportsbluebook.com","LS Info","Fill In Player First Name","MechanicalTurk",100,0.01,2,{},{"id: 5"},{}]

who字符串"id: 5"被解释为单个字符串.

我们不允许通过哈希来耙任务吗？

我们的实习生的计算机在安装mysql2 gem时遇到问题.我们刚刚将他的计算机从OS X 10.6升级到10.8(Mountain Lion).我尝试通过自制软件和64位DMG安装程序安装mysql.我也尝试了对开发工具的符号化(如这里所指出的:在山狮升级后无法安装一些宝石).我们安装了Xcode(4.4)并安装了命令行工具.我们在安装命令行工具后尝试重新启动.

这是他的PATH宣言~/.bashrc:

我的理解是ruby返回函数中评估的最后一个语句.如果函数以一个if计算结果为false 的语句结束,该怎么办？

def thing(input)
  item = input == "hi"
  if item
    []
  end
end

puts thing("hi").class #> Array
puts thing("not hi").class #> NilClass

我喜欢这个功能(nil如果语句为false则false返回),但为什么不返回(从赋值到item)？
