尝试部署到Google AppEngine时出现此错误.我选择了JDK!

我已经清理了项目,将Eclipse重新安装到最新版本,重新安装了所有插件等等.我还编辑了Program …

出于某种原因(可能是更新的gem),Rails现在正在记录我的所有SQL命令.我运行自动测试,他们在测试期间也被发送垃圾邮件.我该如何关闭它？

我尝试将此添加到config/environments/test.rb但它不起作用.logger已经nil.

# ActiveRecord::Base.logger = nil
# ActiveRecord::Base.logger.level = 1

Rails 4.0.0

我尝试了以下内容,但是我看看CSS源代码并没有缩小!我重启了服务器几十次.我在浏览器中关闭了缓存.我也试过'yui-compressor'宝石.

配置/环境/ development.rb

  config.assets.debug = false
  config.assets.css_compressor = :sass
  config.assets.compile = true

的Gemfile

group :assets do
  # Add any compass extensions here
  # Use SCSS for stylesheets
  gem 'sass-rails', '~> 4.0.0'

版

WEBrick 1.3.1,ruby 2.0.0(2013-06-27)[i386-mingw32],Rails 4.0.3

我收到了这个错误,但显然我已经联系了!我15小时前和Heroku订了一张票,但没有得到回应.

C:\>heroku config

Password (typing will be hidden):

$ heroku status
 !    Unable to connect to Heroku API, please check internet connectivity and try again.

我甚至重新安装了Heroku客户端.当这个问题通过Git发生时我甚至推到了Heroku.

我有一个相当困难的问题,我坚持认为如果使用CSS甚至可以实现这一点,我将不胜感激.我有6个div,1-3个需要在左栏中,4-6个在右栏中.当您单击任何div时,它们使用jquery hide()隐藏.我发现困难的部分是当你删除一个div时,我需要它们以特定方式重新排序.请参阅附图,了解订单/重新订购.看到我的进步,感谢一帮助.

https://jsfiddle.net/m44pzvz4/

 <div id="container">
     <div class="child">1</div>
     <div class="child">2</div>
     <div class="child">3</div>
     <div class="child">4</div>
     <div class="child">5</div>
     <div class="child">6</div>  
 </div>

因此,您可以看到,如果删除了任何1-3 div,则4-6中的div需要从左列移动到第一列中的最后一个点.

我试着安装一个包.它没有连接到soft-download.org.我不知道它为什么要连接到那台主机.

内部类是Adapter,内部类是Listener.如何从Listener访问(隐藏)适配器成员/方法？

list.setAdapter(new Adapter() {
  public View getView() {
    // ...
    button.setListener(new Listener() {
      public void onClick() {
        Adapter.this.remove(item);
      }
    );
  }
});

通常要访问外部类成员,你只需要说Outer.this.member,但在这种情况下它给了我以下错误(使用实际的类):

error: not an enclosing class: ArrayAdapter

那么你应该如何从内部内部类访问内部类成员？我不喜欢多级嵌套的匿名类,但在这种情况下,我正在学习一个新的API,并且还不确定它是否更清晰.我已经有一个解决方法,但无论如何都想知道.remove()实际上并没有被内部内部类所掩盖,因此在这种情况下指定类并不是必需的,但是希望在代码中清楚地说明这个remove()方法的位置.我也想知道它是否被遮挡.我相信使用Outer.$6.remove()会起作用,但我不相信也应该这样.

当我提出以下请求时,Google仅提供错误503,并且不会提供任何有用的信息.

我在这里关注文档:https://developers.google.com/android-publisher/v1/purchases/get

我有

android:button="?android:attr/listChoiceIndicatorSingle"

在CheckBox的布局上.我按F3带我去定义,它只是说

    <!-- Drawable to use for single choice indicators. -->
    <attr name="listChoiceIndicatorSingle" format="reference" />

在android-sdk/platforms/android-17/data/res/values/attrs.xml.我搜索了整个文件,这是唯一的情况.

我如何找到它引用的drawable？

如何为Windows XP安装rmagick gem？我已经使用头文件安装了ImageMagick,并安装了DevKit附带的RailsInstaller.org.我不知道在哪里修复这些错误.
