我正在尝试运行rails项目

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

如果我这样做:"捆绑安装"

但我得到了

You have already activated rake 0.9.0, but your Gemfile requires rake 0.8.7

在做的时候

rake db:migrate

我想使用retry与delay功能,我预计1000毫秒的延迟后功能会调用,但它不列入,什么都可以在这里的错误？看看控制台输出,它同时是16:22:48.

我期待那里16:22:48,16:22:59 ......

canCreate: boolean;
getSomeFunction(): Observable<boolean> {
        return new Observable<boolean>(
            observer => {
                const canCreate = null; // this is just null for now, will some value later
                if (canCreate == null) {
                    observer.error('error');
                } else {
                    observer.next(true);
                }
                observer.complete();
            }
        )
    }


this.getSomeFunction()
      .do((value) => {
        this.cCreate = value;
      }, (error) => {
         console.log(error + new Date().toTimeString());
      })
      .delay(1000)
      .retry(10)
      .subscribe(
        value => this.cCreate = value,
        error => {
          this.cCreate = false;
        },
        () …

我有:

SQL Server 2008

数据库名称:database1

我差不多一个月前从"database1"那里备份了.现在,通过某种方式,"database1"在一些表格中搞砸了.

所以我想从上次备份中只恢复那些表.

我正在尝试创建另一个名为"database2"的数据库,并使用旧备份对其进行恢复.

我害怕从备份文件恢复,这可能在"database1"中恢复,我想只在'database2'中重新存储(这是新的)

我可以将gem源重定向到我的Web服务器路径,在那里我将下载所有必需的gem包并放在那里吗？我想通过" bundle install" 使用那些

GemFile将从http://rubygems.org获取那些在那里定义的那些.我经常得到一个错误,如"太多请求"(似乎是互联网拥塞问题).

是否可以将gem源路径重定向到我的本地服务器？

我有以下HTML表单

<form action="https://sandbox.paypal.com/cgi-bin/webscr" method="post" id="paypalpost" name="paypalpost">
                <input type="hidden" name="rm" value="2"/>
                <input type="hidden" name="cmd" value="_xclick">
                <input type="hidden" name="business" value="vbnetdiscuss@yahoo.com">
                <input type="hidden" name="item_name" value="Wedding Gift">
                <input type="hidden" name="currency_code" value="EUR">

            </form>

我已经提到了返回URL为http://developwithus.com/wedding/return.php ,其中,(我从以下网址下载:https://cms.paypal.com/cms_content/US/en_US/files/developer/IPN_PHP_41 .txt并添加

<?php 
print_r('<pre>');
print_r($_POST);
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST …
