我正在尝试使用ruby将文件上传到我的sftp并且我可以ssh并且一切都很好但是我的脚本失败了....这是我的小脚本
require 'rubygems'
require 'net/sftp'
Net::SFTP.start('50.5.54.77', 'root', :password => 'PASSWORD') do |sftp|
# upload a file or directory to the remote host
sftp.upload!("/Users/tamer/sites/sandbox/move_me.txt", "/home")
end
但我一直收到这个错误
ruby sftp.rb
/Library/Ruby/Gems/1.8/gems/net-sftp-2.0.5/lib/net/sftp/operations/upload.rb:313:in `on_open':
Net::SFTP::StatusException open /srv (4, "failure") (Net::SFTP::StatusException)
我有什么不妥的想法
我有一个数组或不同的对象,我想按对象分组.例如
=> [#<Graphic id: 3...">, #<Collection id: 1....">, #<Category id:...">, #<Volume id: 15...">]
all.size
=> 4
我试过了
all.group_by(Object)
但这没有用......关于如何在一个数组中分组对象的任何想法？
我有这个jQuery点击事件
$('#sidebar .nav a span').click(function () {
var sidebar_nav = $(this);
$("#main").load("type_change.php?id="+id, successCallback);
然后我有回调来做绑定
var successCallback = function(responseText, textStatus, XMLHttpRequest) {
//doing all the binding in here
}
有没有办法传递$(this)或者传递sidebar_nav给successCallback函数,所以我可以用它做点什么
好的,所以我有这个代码,允许用户下载一首歌
$file = DIR_DOWNLOAD . $download_info->row['filename'];
$mask = basename($download_info->row['mask']);
$mime = 'application/octet-stream';
$encoding = 'binary';
if (!headers_sent()) {
if (file_exists($file)) {
header('Pragma: public');
header('Expires: 0');
header('Content-Description: File Transfer');
header('Content-Type: ' . $mime);
header('Content-Transfer-Encoding: ' . $encoding);
header('Content-Disposition: attachment; filename=' . ($mask ? $mask : basename($file)));
header('Content-Length: ' . filesize($file));
$file = readfile($file, 'rb');
问题是,如果歌曲中有一个空格,就像sinsita happy 1 SONIFI.mp3用户只会下载一个名为的文本文件sinsita...任何想法如何解决这个问题
好吧,所以我有一个rails应用程序,我试图在postgres数据库上运行迁移,我通常使用mysql,一切都很好,但当我运行命令,我得到这个

guard 'minitest', :cli => '--drb --format doc --color' do

watch(%r|^test/(.*)\/?test_(.*)\.rb|)
watch(%r|^lib/(.*)([^/]+)\.rb|) { |m| "test/#{m[1]}test_#{m[2]}.rb" }

但是当我跑卫时,我得到一个命令提示符
bundle exec guard

22:14:12 - INFO - Guard is now watching at '/Users/trace/Sites/application'

我为什么得到这个提示.任何想法......这里是我正在使用的一些宝石
更新中...
当我跑步all minitest然后测试运行...但为什么我必须运行...任何想法
我正在研究这个PHP项目,我有很多地方正在使用md5.我甚至多次使用它,但是今天我还不清楚它的功能是什么.我意识到它会解密传入的值但是如何撤消它以使其恢复原状.也许我不清楚整个过程,如果有人有关于这个过程的信息我会非常感激
我的部署问题
我跑了帽子部署并得到了这个

role …我使用的是SQL Server 2008,我使用的数据库表的主键不是IDENTITY列(不确定原因).我需要改变它.
我在设计视图中的SQL Server Management Studio中,在列属性下,由于某种原因我无法更改标识规范Yes.
有没有我失踪的东西..我是SQL Server的新手 - 关于我所缺少的任何想法？
