  • Django CMS - not able to upload images through cmsplugin_filer_image

    - by Luke
    i have a problem with a local installation on django cms 2.3.3: i've installed it trough pip, in a separated virtualenv. next i followed the tutorial for settings.py configuration, i started the server. Then in the admin i created an page (home), and i've tried to add an image in the placeholder through the cmsplugin_filer_image, but the upload seems that doesn't work. here's my settings.py: # Django settings for cms1 project. # -*- coding: utf-8 -*- import os gettext = lambda s: s PROJECT_PATH = os.path.abspath(os.path.dirname(__file__)) DEBUG = True TEMPLATE_DEBUG = DEBUG ADMINS = ( # ('Your Name', '[email protected]'), ) MANAGERS = ADMINS DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.

  • ASP.NET MVC - Refresh PartialView when DropDownList changed

    - by Bryan Roth
    I have a search form that is an Ajax form. Within the form is a DropDownList that, when changed, should refresh a PartialView within the Ajax form (via a GET request).

  • add_shown & add_hiding ModalPopupExtender Events

    - by Yousef_Jadallah
        In this topic, I’ll discuss the Client events we usually need while using ModalPopupExtender. The add_shown fires when the ModalPopupExtender had shown and add_hiding fires when the user cancels it by CancelControlID,note that it fires before hiding the modal. They are useful in many cases, for example may you need to set focus to specific Textbox when the user display the modal, or if you need to reset the controls values inside the Modal after it has been hidden. To declare Client event either in pageLoad javascript function or you can attach the function by Sys.Application.add_load like this: Sys.Application.add_load(modalInit); function modalInit() { var modalPopup = $find('mpeID'); modalPopup.add_hiding(onHiding); } function onHiding(sender, args) { } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   I’ll use the first way in the current example. So lets start with the illustration:   1- In this example am using simple panel which contain UserName and Password Textboxes besides submit and cancel buttons, this Panel will be used as PopupControlID in the ModalPopupExtender : <asp:Panel ID="panModal" runat="server" Height="180px" Width="300px" style="display:none" CssClass="ModalWindow"> <table width="100%" > <tr> <td> User Name </td> <td> <asp:TextBox ID="txtName" runat="server"></asp:TextBox> </td> </tr> <tr> <td> Password </td> <td> <asp:TextBox ID="txtPassword" runat="server" TextMode="Password"></asp:TextBox> </td> </tr> </table> <br /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" /> <asp:Button ID="btnCancel" runat="server" Text="Cancel" /> </asp:Panel>   You can use this simple style for the Panel : <style type="text/css"> .ModalWindow { border: solid; border-width:3px; background:#f0f0f0; } </style> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   2- Create the view button (TargetControlID) as you know this contain the ID of the element that activates the modal popup: <asp:Button ID="btnView" runat="server" Text="View" /> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   3-Add the ModalPopupExtender ,moreover don’t forget to add the ScriptManager: <asp:ScriptManager ID="ScriptManager1" runat="server"/> <cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="btnView" PopupControlID="panModal" CancelControlID="btnCancel"/> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }     4-In the pageLoad javascript function inside add_shown event set the focus on the txtName , and inside add_hiding reset the two Textboxes. <script language="javascript" type="text/javascript"> function pageLoad() { $find('ModalPopupExtender1').add_shown(function() { alert('add_shown event fires'); $get('<%=txtName.ClientID%>').focus();   });   $find('ModalPopupExtender1').add_hiding(function() { alert('add_hiding event fires'); $get('<%=txtName.ClientID%>').value = ""; $get('<%=txtPassword.ClientID%>').value = "";   }); }   </script> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   I’ve added the two alerts just to let you show when the event fires.   Hope this simple example show you the benefit and how to use these events.

  • Display cross domain content in IFrame (IE8)

    - by DK
    I realized that IE8 does not allow links from cross domains to be displayed in IFrame. It seems like there are only two Header options that Microsoft allows to modify. X-FRAME-OPTIONS : "DENY" (This does not display any IFrame content ) X-FRAME-OPTIONS : "SAMEORIGIN" (Displays content from the same domain) Is there a work around to allow content from other domains to be displayed? Thanks in advance

  • jqGrid Export to CSV Missing Column Names

    - by user561557
    I have a jqGrid that works perfectly. It contains a pager button to export the grid to a csv file which works and exports the data. However, I also need to have the column names exported with the data and I can't seem to get that to work. My working code follows. jQuery("#detail").jqGrid('navGrid','#pager2', {height:520,width:500,savekey:[true,13],navkeys:[true,38,40],reloadAfterSubmit:false, jqModal:false, closeOnEscape:true, bottominfo:"Fields marked with () are required"}, // edit options {height:520, width:500,savekey:[true,13],reloadAfterSubmit:false,jqModal:false, closeOnEscape:true,bottominfo:"Fields marked with () are required", closeAfterAdd: true}, // add options {reloadAfterSubmit:false,jqModal:false, closeOnEscape:true}, // del options {closeOnEscape:true}, // search options {height:250,width:500,jqModal:false,closeOnEscape:true}, {view:true} // view options ); // add custom button to export the data to excel jQuery("#detail").jqGrid('navButtonAdd','#pager2',{ caption:"", title:"Export to CSV", onClickButton : function () { exportExcel(); }, position:"last" }); // add custom button to print grid jQuery("#detail").jqGrid('navButtonAdd','#pager2',{ caption:"", title:"Print", buttonicon:"ui-icon-print", onClickButton : function () { jQuery('#detail_table').jqprint({ operaSupport: true }); return false; } }); function exportExcel() { var mya=new Array(); mya=jQuery("#detail").getDataIDs(); // Get All IDs var data=jQuery("#detail").getRowData(mya[0]); // Get First row to get the labels var colNames=new Array(); var ii=0; for (var i in data){colNames[ii++]=i;} // capture col names var html=""; for(i=0;i } html=html+"\\n"; // end of line at the end document.forms[0].method='POST'; document.forms[0].action='ajax/csvExport.php'; // send it to server which will open this contents in excel file document.forms[0].target='_blank'; document.forms[0].csvBuffer.value=html; document.forms[0].submit(); }

  • after return PartialView() Url.Actionlink("Action", "Controller"), the Controller is lost

    - by Johannes
    Well the Question is related to a problem I posted before (http://stackoverflow.com/questions/2403899/asp-net-mvc-partial-view-does-not-call-my-action). In practice I've a partial view which contains a Form, after submitting the Form the Controller returns the Partial View. Well the Problem is if I reload the page which contains the partial view the function <%= Url.Action("ChangePassword", "Account") %> returns "Account/ChangePassword", if I submit the form and the partial is returned by the controller. Using return PartialView() the function <%= Url.Action("ChangePassword", "Account") %> returns only "ChangePassword". Any Idea because? The View looks like: <form action="<%= Url.Action("ChangePassword", "Account") %>" method="post" id="jform"> <div> <fieldset> <legend>Account Information</legend> <p> <label for="currentPassword">Current password:</label> <%= Html.Password("currentPassword") %> <%= Html.ValidationMessage("currentPassword") %> </p> <p> <label for="newPassword">New password:</label> <%= Html.Password("newPassword") %> <%= Html.ValidationMessage("newPassword") %> </p> <p> <label for="confirmPassword">Confirm new password:</label> <%= Html.Password("confirmPassword") %> <%= Html.ValidationMessage("confirmPassword") %> </p> <p> <input type="submit" value="Change Password" /> </p> </fieldset> </div> </form> </div> <script> $(function() { $('#jform').submit(function() { $('#jform').ajaxSubmit({ target: '#FmChangePassword' }); return false; }); }); </script> Part of the Controller: if (!ValidateChangePassword(currentPassword, newPassword, confirmPassword)) { return PartialView(ViewData); }

  • How about a new platform for your next API&hellip; a CMS?

    - by Elton Stoneman
    Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2014/05/22/how-about-a-new-platform-for-your-next-apihellip-a.aspxSay what? I’m seeing a type of API emerge which serves static or long-lived resources, which are mostly read-only and have a controlled process to update the data that gets served. Think of something like an app configuration API, where you want a central location for changeable settings. You could use this server side to store database connection strings and keep all your instances in sync, or it could be used client side to push changes out to all users (and potentially driving A/B or MVT testing). That’s a good candidate for a RESTful API which makes proper use of HTTP expiration and validation caching to minimise traffic, but really you want a front end UI where you can edit the current config that the API returns and publish your changes. Sound like a Content Mangement System would be a good fit? I’ve been looking at that and it’s a great fit for this scenario. You get a lot of what you need out of the box, the amount of custom code you need to write is minimal, and you get a whole lot of extra stuff from using CMS which is very useful, but probably not something you’d build if you had to put together a quick UI over your API content (like a publish workflow, fine-grained security and an audit trail). You typically use a CMS for HTML resources, but it’s simple to expose JSON instead – or to do content negotiation to support both, so you can open a resource in a browser and see a nice visual representation, or request it with: Accept=application/json and get the same content rendered as JSON for the app to use. Enter Umbraco Umbraco is an open source .NET CMS that’s been around for a while. It has very good adoption, a lively community and a good release cycle. It’s easy to use, has all the functionality you need for a CMS-driven API, and it’s scalable (although you won’t necessarily put much scale on the CMS layer). In the rest of this post, I’ll build out a simple app config API using Umbraco. We’ll define the structure of the configuration resource by creating a new Document Type and setting custom properties; then we’ll build a very simple Razor template to return configuration documents as JSON; then create a resource and see how it looks. And we’ll look at how you could build this into a wider solution. If you want to try this for yourself, it’s ultra easy – there’s an Umbraco image in the Azure Website gallery, so all you need to to is create a new Website, select Umbraco from the image and complete the installation. It will create a SQL Azure website to store all the content, as well as a Website instance for editing and accessing content. They’re standard Azure resources, so you can scale them as you need. The default install creates a starter site for some HTML content, which you can use to learn your way around (or just delete). 1. Create Configuration Document Type In Umbraco you manage content by creating and modifying documents, and every document has a known type, defining what properties it holds. We’ll create a new Document Type to describe some basic config settings. In the Settings section from the left navigation (spanner icon), expand Document Types and Master, hit the ellipsis and select to create a new Document Type: This will base your new type off the Master type, which gives you some existing properties that we’ll use – like the Page Title which will be the resource URL. In the Generic Properties tab for the new Document Type, you set the properties you’ll be able to edit and return for the resource: Here I’ve added a text string where I’ll set a default cache lifespan, an image which I can use for a banner display, and a date which could show the user when the next release is due. This is the sort of thing that sits nicely in an app config API. It’s likely to change during the life of the product, but not very often, so it’s good to have a centralised place where you can make and publish changes easily and safely. It also enables A/B and MVT testing, as you can change the response each client gets based on your set logic, and their apps will behave differently without needing a release. 2. Define the response template Now we’ve defined the structure of the resource (as a document), in Umbraco we can define a C# Razor template to say how that resource gets rendered to the client. If you only want to provide JSON, it’s easy to render the content of the document by building each property in the response (Umbraco uses dynamic objects so you can specify document properties as object properties), or you can support content negotiation with very little effort. Here’s a template to render the document as HTML or JSON depending on the Accept header, using JSON.NET for the API rendering: @inherits Umbraco.Web.Mvc.UmbracoTemplatePage @using Newtonsoft.Json @{ Layout = null; } @if(UmbracoContext.HttpContext.Request.Headers["accept"] != null &amp;&amp; UmbracoContext.HttpContext.Request.Headers["accept"] == "application/json") { Response.ContentType = "application/json"; @Html.Raw(JsonConvert.SerializeObject(new { cacheLifespan = CurrentPage.cacheLifespan, bannerImageUrl = CurrentPage.bannerImage, nextReleaseDate = CurrentPage.nextReleaseDate })) } else { <h1>App configuration</h1> <p>Cache lifespan: <b>@CurrentPage.cacheLifespan</b></p> <p>Banner Image: </p> <img src="@CurrentPage.bannerImage"> <p>Next Release Date: <b>@CurrentPage.nextReleaseDate</b></p> } That’s a rough-and ready example of what you can do. You could make it completely generic and just render all the document’s properties as JSON, but having a specific template for each resource gives you control over what gets sent out. And the templates are evaluated at run-time, so if you need to change the output – or extend it, say to add caching response headers – you just edit the template and save, and the next client request gets rendered from the new template. No code to build and ship. 3. Create the content With your document type created, in  the Content pane you can create a new instance of that document, where Umbraco gives you a nice UI to input values for the properties we set up on the Document Type: Here I’ve set the cache lifespan to an xs:duration value, uploaded an image for the banner and specified a release date. Each property gets the appropriate input control – text box, file upload and date picker. At the top of the page is the name of the resource – myapp in this example. That specifies the URL for the resource, so if I had a DNS entry pointing to my Umbraco instance, I could access the config with a URL like http://static.x.y.z.com/config/myapp. The setup is all done now, so when we publish this resource it’ll be available to access.  4. Access the resource Now if you open  that URL in the browser, you’ll see the HTML version rendered: - complete with the  image and formatted date. Umbraco lets you save changes and preview them before publishing, so the HTML view could be a good way of showing editors their changes in a usable view, before they confirm them. If you browse the same URL from a REST client, specifying the Accept=application/json request header, you get this response:   That’s the exact same resource, with a managed UI to publish it, being accessed as HTML or JSON with a tiny amount of effort. 5. The wider landscape If you have fairy stable content to expose as an API, I think  this approach is really worth considering. Umbraco scales very nicely, but in a typical solution you probably wouldn’t need it to. When you have additional requirements, like logging API access requests - but doing it out-of-band so clients aren’t impacted, you can put a very thin API layer on top of Umbraco, and cache the CMS responses in your API layer:   Here the API does a passthrough to CMS, so the CMS still controls the content, but it caches the response. If the response is cached for 1 minute, then Umbraco only needs to handle 1 request per minute (multiplied by the number of API instances), so if you need to support 1000s of request per second, you’re scaling a thin, simple API layer rather than having to scale the more complex CMS infrastructure (including the database). This diagram also shows an approach to logging, by asynchronously publishing a message to a queue (Redis in this case), which can be picked up later and persisted by a different process. Does it work? Beautifully. Using Azure, I spiked the solution above (including the Redis logging framework which I’ll blog about later) in half a day. That included setting up different roles in Umbraco to demonstrate a managed workflow for publishing changes, and a couple of document types representing different resources. Is it maintainable? We have three moving parts, which are all managed resources in Azure –  an Azure Website for Umbraco which may need a couple of instances for HA (or may not, depending on how long the content can be cached), a message queue (Redis is in preview in Azure, but you can easily use Service Bus Queues if performance is less of a concern), and the Web Role for the API. Two of the components are off-the-shelf, from open source projects, and the only custom code is the API which is very simple. Does it scale? Pretty nicely. With a single Umbraco instance running as an Azure Website, and with 4x instances for my API layer (Standard sized Web Roles), I got just under 4,000 requests per second served reliably, with a Worker Role in the background saving the access logs. So we had a nice UI to publish app config changes, with a friendly Web preview and a publishing workflow, capable of supporting 14 million requests in an hour, with less than a day’s effort. Worth considering if you’re publishing long-lived resources through your API.

  • How do I correctly Re-render a Recaptcha in ASP.NET MVC 2 after an AJAX POST

    - by Eoin Campbell
    Ok... I've downloaded and implemented this Recaptcha implementation for MVC which uses the ModelState to confirm the validity of the captcha control. It works brilliantly... except when I start to use it in an AJAX Form. In a nutshell, when a div is re-rendered with AJAX, the ReCaptcha that it should contain does not appear, even though the relevant <scripts> are in the source after the partial render. Code Below. using (Ajax.BeginForm("CreateComment", "Blog", new AjaxOptions() { HttpMethod = "POST", UpdateTargetId = "CommentAdd", OnComplete="ReloadRecaptcha", OnSuccess = "ShowComment", OnFailure = "ShowComment", OnBegin = "HideComment" })) {%> <fieldset class="comment"> <legend>Add New Comment</legend> <%= Html.ValidationSummary()%> <table class="postdetails"> <tbody> <tr> <td rowspan="3" id="blahCaptcha"> <%= Html.CreateRecaptcha("recaptcha", "blackglass") %> </td> .... Remainder of Form Omitted for Brevity I've confirmed the Form is perfectly functional when the Recaptcha Control is not present and the Javascript calls in the AjaxOptions are all working fine. The problem is that if the ModelState is Invalid as a result of the Recaptcha or some other validation, then the ActionResult returns the View to reshow the form. [RecaptchaFilter(IgnoreOnMobile = true)] [HttpPost] public ActionResult CreateComment(Comment c) { if (ModelState.IsValid) { try { //Code to insert Comment To DB return Content("Thank You"); } catch { ModelState.AddRuleViolations(c.GetRuleViolations()); } } else { ModelState.AddRuleViolations(c.GetRuleViolations()); } return View("CreateComment", c); } When it's InValid and the form posts back, for some reason the ReCaptcha Control does not re-render. I've checked the source and the <script> & <noscript> blocks are present in the HTML so the HTML Helper function below is obviously working <%= Html.CreateRecaptcha("recaptcha", "blackglass") %> I assume this has something to do with scripts injected into the DOM by AJAX are not re-executed. As you can see from the HTML snippet above, I've tried to add an OnComplete= javascript function to re-create the Captcha on the client side, but although the script executes with no errors, it doesn't work. OnComplete Function is. function ReloadRecaptcha() { Recaptcha.create("my-pub-key", 'blahCaptcha', { //blahCaptcha is the ID of the <td> where the ReCaptcha should go. theme: 'blackglass' }); } Can anyone shed any light on this ? Thanks, Eoin C

  • CentOS 5.4 NFS v4 client file permissions differ from original files & NFS Share file contents

    - by p4guru
    Having a strange problem with NFS share and file permissions on the 1 out of the 2 NFS clients, web1 has file permissions issues but web2 is fine. web1 and web2 are load balanced web servers. So questions are: how do I ensure NFS share file contents retain the same permissions for user/group as the original files on web1 server like they do on web2 server ? how do I reverse what I did on web1, i tried unmount command and said command not found ? Information: I'm using 3 dedicated server setup. All 3 servers CentOS 5.4 64bit based. servers are as follows: web1 - nfs client with file permissions issues web2 - nfs client file permissions are OKAY db1 - nfs share at /nfsroot web2 nfs client was setup by my web host, while web1 was setup by me. I did the following commands on web1 and it worked with updating db1 nfsroot share at /nfsroot/site_css with latest files on web1 but the file permissions don't stick even if i use tar with -p command to perserve file permissions ? cd /home/username/public_html/forums/script/ tar -zcp site_css/ > site_css.tar.gz mount -t nfs4 nfsshareipaddress:/site_css /home/username/public_html/forums/scripts/site_css/ -o rw,soft cd /home/username/public_html/forums/script/ tar -zxf site_css.tar.gz But checking on web1 file permissions no longer username user/group but owned by nobody ? but web2 file permissions correct ?

  • CloudBerry Online Backup 1.5 for Windows Home Server

    - by The Geek
    Overview CloudBerry Online Backup version 1.5 is a front end application for Amazon S3 storage for backing up your Windows Home Server data. It makes backing up your essential data to Amazon S3 an easy process in the event the disaster strikes. Installation You install the Cloudberry Addin as you do for any addins for Windows Home Server. On a PC on your network, browse to the shared folders on your server and open the Add-Ins folder and copy over WHS_CloudBerryOnlineBackupSetup_v1.5.0.81S3o.msi (link below), then close out of the folder. Next launch the Windows Home Server Console, click Settings, then Add-Ins. Click on the Available tab and click the Install button. It installs very quickly, and when you get the Installation Succeeded dialog click OK. You will lose connection through the Console, just click OK, then reconnect. After reconnecting, you’ll see CloudBerry Backup has been installed, and you can begin using it. You can setup a backup plan right away or find out what’s new with version 1.5. Amazon S3 Account If you don’t already have an Amazon S3 account, you’ll be prompted to create a new one. Click on the Create an account hyperlink, which takes you to the Amazon S3 page where you can sign up. After reviewing the functionality of Amazon S3, click on the Sign Up for Amazon S3 button. Enter in your contact information and accept the Amazon Web Services Customer Agreement. You’re then shown their pricing for storage plans. The amount of storage space you use will depend on your needs. It’s relatively cheap for smaller amounts of data. Just keep in mind the more data you store and download, the more S3 is going to cost. Note: Amazon S3 is introducing Reduced Redundancy Storage which will lower the cost of the data stored on S3. CloudBerry 1.5 will support this new feature. You can find out more about this new pricing structure. Note: Keep in mind that after you first sign up for an Amazon S3 account, it can take up to 24 hours to be authorized. In fact, you may want to sign up for the S3 account before installing the Add-In. After you sign up for your S3 Account, you’ll be given access credentials which you can enter in and create a Storage Bucket name. Features & Use CloudBerry is wizard driven, straight-forward and easy to use. Here we take a look at creating a backup plan. To begin, click on the Setup Backup Plan button to kick off the wizard. Select your backup mode based on the amount of features you want. In our example we’re going to select Advanced Mode as it offers more features than Simple Mode. Select your backup storage account or create a new one. You can select a default account by checking Use currently selected account as default. Now you can go through and select the files and folders you want to backup from your home server. Check the box Show physical drives to get more of a selection of files and folders. This also allows you to backup files from your data drive as well. It has full support for drive extenders so you can backup your shares as well. The cool thing about Cloudberry is it allows you to drill down specific files and folders unlike other WHS backup utilities. Next you can use advanced filters to specify files and/or folders to skip if you want. There are compression and encryption options as well. This will save storage space, bandwidth, and keep your data secure. Purge Options allow you to customize options for getting rid of older files. You can also select the option to delete files from the S3 service that have been deleted locally. Be careful with this option however, as you won’t be able to restore files if you delete them locally. You have some nice scheduling options from running backups manually, specific date and time, or recurring daily, weekly or monthly. Receive email notifications in all cases or when a backup fails. This is a good option so you know if things were successful or something failed, and you need to back it up manually. Email notifications… Give your plan a name… Then if the summary page looks good you can continue, or still go back at this point if something doesn’t look correct and needs adjusting. That’s it! You’re ready to go, and you have an option to start your first backup right away. After you’ve created a backup plan, you can go in and edit, delete, view history, or restore files. Restoring Files using CloudBerry To restore data from your backups kick off the Restore Wizard and select the backup to restore from. You can select the last backup, a specific point in time, or manually browse through the files. Browse through the directory and select the files you need to restore. Choose the destination to restore the files to. You can select from the original location, a specific location, to overwrite existing files, or set the location as the default for future restores. If the files are encrypted, enter in the correct passwords. If the summary looks good, click on Next to start the restore process. You’ll be shown a progress bar at the bottom of the screen while the files are restored. After the process has completed, close out of the Restore Wizard. In this example we restored a couple of music files to the desktop of Windows Home Server… But as shown above you can save them to the original location, other network locations, or WHS shared folders. This can make it a lot easier to keep track of files you’ve restored. You can also access different options for CloudBerry by clicking Settings in WHS Console then CloudBerry Backup. Here you can set up a new storage account, check for updates, app options, Diagnostics, and send feedback. Under Options there are several settings you can tweak to get the best experience for your WHS backups. CloudBerry Web Interface Another nice feature is the CloudBerry Web Interface so you can access your data from anywhere you have an Internet connection. To check it out in WHS Console, click on the Backup Web Interface link…you’ll probably want to bookmark the link in your favorite browser. Note: This feature is still in beta and at the time of this review, the Web Interface wasn’t up and running so we weren’t able to test it out. Performance The Cloudberry app works very well through the Windows Home Server Console. The amount of time it takes to backup or restore your data will depend on the speed of your Internet connection and size of the files. In our tests, backing up 1GB of data to the Amazon S3 account took around an hour, but we were running it on a DSL with limited upload speeds so your mileage will vary. Product Support In our experience, the team at CloudBerry offered great support in a timely manner when contacting them. You can fill out a help request through a form on their website and they also have a community forum. Conclusion We were very pleased with CloudBerry Online Backup for WHS. It’s wizard driven interface makes it extremely easy to use, and offers comprehensive backup choices for your Amazon S3 account. CloudBerry will only backup files that have been modified, so if files haven’t been changed, they won’t be backed up again.They offer a free 15 day trial and is $29.99 after that for a full license. Once you buy the app you own it, and charges to your S3 account will vary depending on the amount of data you upload. If you’re looking for an effective and easy to use front end application to backup your Windows Home Server data to your Amazon S3 account, CloudBerry is a recommended affordable choice.

  • Dynamically create and save image with Django and PIL/Django-Photologue

    - by Travis
    I want to generate a page of html with dynamic content and then save the result as an image as well as display the page to the user. So, user signs up to attend conference and gives their name and org. That data is combined with html/css elements to show what their id badge for the conference will look like (their name and org on top of our conference logo background) for preview. Upon approval, the page is saved on the server to an image format (PNG, PDF or JPG) to be printed onto a physical badge by an admin later. I am using Django and django-photologue powered by PIL. The view might look like this # app/views.py def badgepreview(request, attendee_id): u = User.objects.get(id=attendee_id) name = u.name org = u.org return render_to_response('app/badgepreview.html', {'name':name,'org':org,}, context_instance = RequestContext(request), ) The template could look like this {# templates/app/badgepreview.html #} {% extends "base.html" %} {% block page_body %} <div style='background:url(/site_media/img/logo_bg.png) no-repeat;'> <h4>{{ name }}</h4> <h4>{{ org }}</h4> </div> {% endblock %} simple, but how do I save the result? Or is there a better way to get this done?

  • Facebook require_login() in iFrame App

    - by LapKom
    Hi, I have serious problem with iframe application. I need to use many external JS libraries and other dynamic stuuf so FMBL application can't be done. When I call require_login() I get applicaition installing dialog when app is not already installed, which is ok. But then after authorization application enters an endless redirect loop with parameters like auth_token, installed and so. Yesterday I managed to fix this, but today it's broken again... What the heck is happening with FB? It's driving me crazy to find a sollution, none of ones found on net doesn't seem to be working. So far I tried: http://abhirama.wordpress.com/2010/03/07/facebook-iframe-xfbml-app/ (7th march 2010!) http://forum.developers.facebook.com/viewtopic.php?pid=156092 http://www.keywordintellect.com/facebook-development/how-to-set-up-a-facebook-iframe-application-in-php-in-5-minutes/ http://www.markdeepwell.com/2010/02/validating-a-facebook-session-within-an-iframe/ http://forum.developers.facebook.com/viewtopic.php?pid=210449 http://www.ajaxlines.com/ajax/stuff/article/facebook_fbml_rendering_in_iframe_application.php http://www.aratide.com/php/solving-the-break-out-issue-in-iframe-facebook-applications/ None of the above worked... According to those and some FB docs: http://wiki.developers.facebook.com/index.php/FB_RequireFeatures http://wiki.developers.facebook.com/index.php/Cross_Domain_Communication_Channel My example test files look as follow: <?php //Link in library. require_once '../application/vendor/Facebook/facebook.php'; //Authentication Keys $appapikey = 'XXXX'; $appsecret = 'XXXX'; //Construct the class $facebook = new Facebook($appapikey, $appsecret); //Require login $user_id = $facebook->require_login(); ?> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml"> <head> <title></title> </head> <body> <script src="http://static.ak.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> This is you: <fb:name uid="<?php echo $user_id?>"></fb:name> <?php var_dump($facebook->$this->facebook->api_client->friends_get())?> <script type="text/javascript"> FB_RequireFeatures(["XFBML"], function(){ FB.Facebook.init("<?=$appapikey?>", "xd_receiver.html"); }); </script> </body> </html> And cross-domain file xd_receiver.html is: <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>cross-domain receiver page</title> </head> <body> <script src="http://static.ak.facebook.com/js/api_lib/v0.4/XdCommReceiver.js" type="text/javascript"></script> </body> </html> How do I get it working? I'm using Kohana framework to do this and already replaced header('Location') with url::redirect() in facebook php library.

  • Delete a div id using ajax and jquery and delete from DB

    - by Matt Nathanson
    I've got several div id's, each containing a different client. I want to be able to click the delete button and using ajax and jquery delete the specific div from the database. I'm getting success in AJAX but it's not deleting anything from the DB. And then obviously, upon deletion, I would like the container to reload dynamically. help!!! function DeleteClient(){ var yes = confirm("Whoa there chief! Do you really want to DELETE this client?"); if (yes == 1) { dataToLoad = 'clientID=' + clientID + '&deleteclient=yes', $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, success: function(html) { alert('Client' + clientID + ' should have been deleted from the database.'); $('#clientscontainer').html(html); }, error: function() { alert('error'); }});}; };

  • MySQL InnoDB Corruption after power outage, possible to recover?

    - by Tim Hackett
    Hey Guys, I recently started trying to get Redmine up and running after a power outage that seems to have corrupted our InnoDB database in MySQL. Redmine had an extensive set of documentation that I would like to get even if redmine isn't able to run. The service fails on startup. I have tried inserting innodb_force_recovery = 4 per the documentation from the url in the error log. (also tried 1 thru 6 as I have backed up all directories after the corruption) I have verified through "mysqld-nt --print-defaults" that it is starting with the recovery option in the params. The machine is running Windows Server 2003 SP2, Xeon E5335 with 2GB RAM, MySQL is not mirrored to another machine, nor is the machine a mirror. I do not have any backups because the previous person did not set them up.

    I'm working through the book "The Definitive Guide to Django" and am stuck on a piece of code. This is the code in my settings.py: ROOT_URLCONF = 'mysite.urls' I have the following code in my urls.py from django.conf.urls.defaults import * from mysite.views import hello, my_homepage_view urlpatterns = patterns('', ('^hello/$', hello), ) urlpatterns = patterns('', ('^time/$', current_datetime), ) And the following is the code in my views.py file: from django.http import HttpResponse import datetime def hello(request): return HttpResponse("Hello World") def current_datetime(request): now = datetime.datetime.now() html = "<html><body>It is now %s.</body></html>" % now return HttpResponse(html) Yet, I get the following error when I test the code in the development server. NameError at /time/ name 'current_datetime' is not defined Can someone help me out here? This really is just a copy-paste from the book. I don't see any mistyping.

  • Rails Associations - Callback Sequence/Magic

    - by satynos
    Taking following association declaration as an example: class Post has_many :comments end Just by declaring the has_many :comments, ActiveRecord adds several methods of which I am particularly interested in comments which returns array of comments. I browsed through the code and following seems to be the callback sequence: def has_many(association_id, options = {}, &extension) reflection = create_has_many_reflection(association_id, options, &extension) configure_dependency_for_has_many(reflection) add_association_callbacks(reflection.name, reflection.options) if options[:through] collection_accessor_methods(reflection, HasManyThroughAssociation) else collection_accessor_methods(reflection, HasManyAssociation) end end def collection_accessor_methods(reflection, association_proxy_class, writer = true) collection_reader_method(reflection, association_proxy_class) if writer define_method("#{reflection.name}=") do |new_value| # Loads proxy class instance (defined in collection_reader_method) if not already loaded association = send(reflection.name) association.replace(new_value) association end define_method("#{reflection.name.to_s.singularize}_ids=") do |new_value| ids = (new_value || []).reject { |nid| nid.blank? } send("#{reflection.name}=", reflection.class_name.constantize.find(ids)) end end end def collection_reader_method(reflection, association_proxy_class) define_method(reflection.name) do |*params| force_reload = params.first unless params.empty? association = association_instance_get(reflection.name) unless association association = association_proxy_class.new(self, reflection) association_instance_set(reflection.name, association) end association.reload if force_reload association end define_method("#{reflection.name.to_s.singularize}_ids") do if send(reflection.name).loaded? || reflection.options[:finder_sql] send(reflection.name).map(&:id) else send(reflection.name).all(:select => "#{reflection.quoted_table_name}.#{reflection.klass.primary_key}").map(&:id) end end end In this sequence of callbacks, where exactly is the actual SQL being executed for retrieving the comments when I do @post.comments ?
