How can we avoid this behavior so that if Link Description is set on the General Link Field then it takes that value and not fallback to Item name ? Glass Mapper is using the Item name of the target item for type of Internal Link in General Link Field. This behavior is because of the below
case "internal":
var urlOptions = Utilities.CreateUrlOptions(config.UrlOptions);
if (linkField.TargetItem == null) link.Url = string.Empty;
else link.Url = LinkManager.GetItemUrl(linkField.TargetItem, urlOptions);
link.Type = LinkType.Internal;
link.TargetId = linkField.TargetID.Guid;
link.Text = linkField.Text.IsNullOrEmpty() ? (linkField.TargetItem == null ? string.Empty : linkField.TargetItem.Name) : linkField.Text;
break;
in the SitecoreFieldLinkMapper.cs class. I am able to override this class and then register the Component to use the new overridden class to avoid this behavior. However this doesn't work in Page Editor and it doesn't use the new overridden class which has been registered using below code
container.Register(Component.For<Glass.Mapper.AbstractDataMapper>().ImplementedBy<MyProjectSitecoreFieldLinkMapper>().LifestyleCustom<NoTrackLifestyleManager>());
The page editor is not honoring this one. It looks like it is using different technique for resolving the dependency.
This is actually the default behavior of the Sitecore. So Glass is actually doing the right thing. I have to do some other tricks to make it work with my situation.

We just updated our project to use Glass.Mapper V3. We LOVE it. But we've encountered an issue. It doesn't seem to respect language fallback.
We have our site set up so that if a user picks a non-default language, they will see the item of that language if it exists. If not, they will see the default ("fallback") language version. We have also set this up at the field level, so that if there is a non-default version of an item but not all the fields are changed, any unchanged fields will fall back to the default language version's value for that field.
Is there anything we can do to enable Glass to use language fallback?
I am updating this with a bit of background on why we do the check. If you ask for a Sitecore item that doesn't exist you get a null value, so that is simple to handle. However if you ask for a Sitecore item that doesn't exist in that particular language returns an item with no versions. This means we have to do this check because otherwise Glass would end up returning empty class which I don't think makes much sense.
This answer will get a little experimental.
First in the the Spherical.cs file you need to disable the check:
protected void Application_BeginRequest()
{
Sitecore.Context.Items["Disable"] = new VersionCountDisabler();
}
We can then move the check to later on to the Object Construction pipeline. First create a task:
public class FallbackCheckTask : IObjectConstructionTask
{
public void Execute(ObjectConstructionArgs args)
{
if (args.Result == null)
{
var scContext = args.AbstractTypeCreationContext as SitecoreTypeCreationContext;
if (scContext.Item == null)
{
args.AbortPipeline();
return;
}
//this checks to see if the item was created by the fallback module
if (scContext.Item is Sitecore.Data.Managers.StubItem)
{
return;
}
// we could be trying to convert rendering parameters to a glass model, and if so, just return.
if (String.Compare(scContext.Item.Paths.FullPath, "[orphan]/renderingParameters", true) == 0)
{
return;
}
if (scContext.Item.Versions.Count == 0)
{
args.AbortPipeline();
return;
}
}
}
}
Then finally register this task in the GlassMapperScCustom class:
public static void CastleConfig(IWindsorContainer container){
var config = new Config();
container.Register(
Component.For<IObjectConstructionTask>().ImplementedBy<FallbackCheckTask>().LifestyleTransient()
);
container.Install(new SitecoreInstaller(config));
}
I haven't tested this but it should in theory work <- disclaimer ;-)
There are few potential issues with provided solution when sitecore 7 (7.2) + IoC + solr + mvc is used.
When using IoC ex Winsdor please make sure that your Global.asax looks like this one <%# Application Codebehind="Global.asax.cs" Inherits="Sitecore.ContentSearch.SolrProvider.CastleWindsorIntegration.WindsorApplication" Language="C#" %>. Once, by mistake this file has been changed to <%# Application Codebehind="Global.asax.cs" Inherits="Merck.Manuals.Web.Global" Language="C#" %> and language fallback was not working. Also the errors we were getting wasn't descriptive as we thought that solr schema is incorrect.
Code Sitecore.Context.Items["Disable"] = new VersionCountDisabler(); can be added to PreprocessRequestProcessor and it works fine which is better solution that modifying global.asax.
Is there any way to parametise the Datasource for the 'source' field in the Template Builder?
We have a multisite setup. As part of this it would save a lot of time and irritation if we could point our Droptrees and Treelists point at the appropriate locations rather than common parents.
For instance:
Content
--Site1
--Data
--Site2
--Data
Instead of having to point our site at the root Content folder I want to point it at the individual data folders, so I want to do something like:
DataSource=/sitecore/content/$sitename/Data
I can't find any articles on this. Is it something that's possible?
Not by default, but you can use this technique to code your datasources:
http://newguid.net/sitecore/2013/coded-field-datasources-in-sitecore/
You could possibly use relative paths if it fits with the rest of your site structure. It could be as simple as:
./Data
But if the fields are on random items all over the tree, that might not be helpul.
Otherwise try looking at:
How to use sitecore query in datasource location? (dynamic datasouce)
You might want to look at using a Querable Datasource Location and plugging into the getRenderingDatasource pipeline.
It's really going to depend on your use cases. The thing I like about this solution is there is no need to create a whole bunch of controls which effectively do he same thing as the default Sitecore ones, and you don't have to individually code up each datasource you require - just set the query you need to get the data. You can also just set the datasource query in the __standard values for the templates.
This is very similar to Holger's suggestion, I just think this code is neater :)
Since Sitecore 7 requires VS 2012 and our company isn't going to upgrade any time soon I was forced to find a Sitecore 6 solution to this.
Drawing on this article and this one I came up with this solution.
public class SCWTreeList : TreeList
{
protected override void OnLoad(EventArgs e)
{
if (!String.IsNullOrEmpty(Source))
this.Source = SourceQuery.Resolve(SContext.ContentDatabase.Items[ItemID], Source);
base.OnLoad(e);
}
}
This creates a custom TreeList control and passes it's Source field through to a class to handle it. All that class needs to do is resolve anything you have in the Source field into a sitecore query path which can then be reassigned to the source field. This will then go on to be handled by Sitecore's own query engine.
So for our multi-site solution it enabled paths such as this:
{A588F1CE-3BB7-46FA-AFF1-3918E8925E09}/$sitename
To resolve to paths such as this:
/sitecore/medialibrary/Product Images/Site2
Our controls will then only show items for the correct site.
This is the method that handles resolving the GUIDs and tokens:
public static string Resolve(Item item, string query)
{
// Resolve tokens
if (query.Contains("$"))
{
MatchCollection matches = Regex.Matches(query, "\\$[a-z]+");
foreach (Match match in matches)
query = query.Replace(match.Value, ResolveToken(item, match.Value));
}
// Resolve GUIDs.
MatchCollection guidMatches = Regex.Matches(query, "^{[a-zA-Z0-9-]+}");
foreach (Match match in guidMatches)
{
Guid guid = Guid.Parse(match.Value);
Item queryItem = SContext.ContentDatabase.GetItem(new ID(guid));
if (item != null)
query = query.Replace(match.Value, queryItem.Paths.FullPath);
}
return query;
}
Token handling below, as you can see it requires that any item using the $siteref token is inside an Site Folder item that we created. That allows us to use a field which contains the name that all of our multi-site content folders must follow - Site Reference. As long at that naming convention is obeyed it allows us to reference folders within the media library or any other shared content within Sitecore.
static string ResolveToken(Item root, string token)
{
switch (token)
{
case "$siteref":
string sRef = string.Empty;
Item siteFolder = root.Axes.GetAncestors().First(x => x.TemplateID.Guid == TemplateKeys.CMS.SiteFolder);
if (siteFolder != null)
sRef = siteFolder.Fields["Site Reference"].Value;
return sRef;
}
throw new Exception("Token '" + token + "' is not recognised. Please disable wishful thinking and try again.");
}
So far this works for TreeLists, DropTrees and DropLists. It would be nice to get it working with DropLinks but this method does not seem to work.
This feels like scratching the surface, I'm sure there's a lot more you could do with this approach.
Anyone knows how to generate links in sitecore with ID instead of item path?
If you use GetMediaUrl method from the API, I can get this URL:
/~/media/Images/Archive/content/News and Events/News_and_Events_Level2/20070419162739/iwhiz3.jpg
The problem with this approach is that if someone changes the media item name, removes it somewhere or deletes it, the above link will break.
I notice if I insert a media link from rich text editor, I get the link as below:
/~/media/14BDED00E4D64DFD8F74019AED4D74EB.ashx
The second link is better because it's using the item id, so if the actual media item is renamed, removed, or deleted, all related links will be updated too. On top of that, when Sitecore renders the page, it will actually convert the above link and display the item path so it's readable.
I'm using Sitecore 6.5 and currently doing content migration so I need to make sure all internal links are updated properly.
May I know if there is a method to generate the second link by using sitecore API?
Thanks!
The GetMediaItemUrl extension method seems to give you what you want.
public static class ItemExtensions
{
public static string GetMediaItemUrl(this Item item)
{
var mediaUrlOptions = new MediaUrlOptions() { UseItemPath = false, AbsolutePath = true };
return Sitecore.Resources.Media.MediaManager.GetMediaUrl(item, mediaUrlOptions);
}
}
[TestFixture]
public class when_using_items_extensions
{
[Test]
public void a_url_based_on_media_item_id_can_be_generated()
{
// Arrange
Database db = global::Sitecore.Configuration.Factory.GetDatabase("master");
Item item = db.GetItem("/sitecore/media library/Images/MyImage");
// Act
var mediaUrl = item.GetMediaItemUrl();
// Assert
Assert.That(mediaUrl, Is.EqualTo("/~/media/17A1341ABEEC46788F2159843DCEAB03.ashx"));
}
}
These are called dynamic links and you can normally generate them using the LinkManager e.g:
Sitecore.Links.LinkManager.GetDynamicUrl(item)
.. but I'm not sure of the method to do this with Media links (there probably is one but I cant seem to find it and its not on MediaManager) but the basic syntax is:
"/~/media/" + item.ID.ToShortID() + ".ashx"
If you always want to use ID's instead of paths, you can change this setting in webconfig to false (like this):
<setting name="Media.UseItemPaths" value="false"/>`
Here is what the webconfig describes about it:
MEDIA - USE ITEM PATHS FOR URLS
This setting controls if item paths are used for constructing media URLs.
If false, short ids will be used.
Default value: true
Then you can use the default implementation (without additional parameters):
Sitecore.Resources.Media.MediaManager.GetMediaUrl(item);
This is what I use:
var imgField = ((Sitecore.Data.Fields.ImageField)currentItem.Fields["Icon"]);
MediaUrlOptions opt = new MediaUrlOptions();
opt.AlwaysIncludeServerUrl = true;
// Absolute Path works as well. So either use AbsolutePath or AlwaysIncludeServerUrl
opt.AbsolutePath = true;
string mediaUrl = MediaManager.GetMediaUrl(imgField.MediaItem, opt);
I am looking for a quick and dirty way to query the layouts files of a particular page by its friendly url. This is probably easy, but I can't find the solution.
Basically I want to say something like the following. Pseudo-code:
var mainpage = Sitecore.EasyQueryUtility.GetItemByFriendlyUrl(requestedUrl);
or
var mainpage = Sitecore.EasyQueryUtility.GetOppositeOfFriendlyUrl(friendlyurl);
It sounds like you want to do two things here:
Determine an item based on its rendered URL in the address bar (i.e. friendly URL)
Determine the layout being used by the item once you determine the item.
If those are correct, hopefully this can help you out:
Note: untested code I did on-the-fly
// if you have the full URL with protocol and host
public static Item GetItemFromUrl(string url)
{
string path = new Uri(url).PathAndQuery;
return GetItemFromPath(path);
}
// if you have just the path after the hostname
public static Item GetItemFromPath(string path)
{
// remove query string
if(path.Contains("?"))
path = path.split('?')[0];
path = path.Replace(".aspx", "");
return Sitecore.Context.Database.GetItem(path);
}
Once you have the item you can get the layout's name like so:
item.Visualization.GetLayout(Sitecore.Context.Device).Name;
Or the layout's physical file path to the ASPX:
item.Visualization.GetLayout(Sitecore.Context.Device).FilePath;
If you want to get the path of the aspx file which is used for the layout of your page, you can use:
Sitecore.Context.Item.Visualization.Layout.FilePath
I may have misunderstood you but if you want to control the format of friendly URLs you can set several attributes via the Sitecore.Links.UrlOptions class and pass an instance of this in to the link manager. See here for more details. (Note - the LinkManager class is only available from SiteCore 6 I beleive).
The code you would end up with looks like this:
Sitecore.Links.UrlOptions urlOptions = (Sitecore.Links.UrlOptions)Sitecore.Links.UrlOptions.DefaultOptions.Clone();
urlOptions.SiteResolving = Sitecore.Configuration.Settings.Rendering.SiteResolving;
string url = Sitecore.Links.LinkManager.GetItemUrl(item, urlOptions);
You can then set fields like AddAspxExtension on the urlOptions you pass in.
As you can see, the process is reliant on you passing in an item - whether it be obtained via the current context or retrieved from the URL you start off with.
If you were asking about obtaining the layout definition item, take a look at this which shows you how.
my question is basically the same as #Bob Black's Cannot access sitecore item field via API but I agree with #techphoria414 that the accepted solution is not necessary and in my case does not work.
In my own words, I have a template Departure that I have been using for about a year now creating and updating items programmatically. I have added a new field Ship to the template. When I create a new item the field comes up as null when I try to access it using departure.Fields["Ship"]. If I step over the line causing the exception then after calling departure.Editing.EndEdit() I can then see the Ship field if I call departure.Fields.ToList(). If I add the template to a content item via the Sitecore GUI I can see the field and use it, and if I look at a content item which is based on the template I can see the new field too. So it is only when I access the template/item programmatically that it is null.
I have sitecore running on my local machine with a local sqlserver, and publish to my local machine.
Here is my code
String ship = "MSDisaster";
foreach (Language language in SiteLanguages)
{
departure = departure.Database.GetItem(departure.ID, language);
departure.Editing.BeginEdit();
try
{
departure.Fields["StartDate"].Value = GetSitecoreDateString(xDep, "StartDate");
departure.Fields["EndDate"].Value = GetSitecoreDateString(xDep, "EndDate");
departure.Fields["Guaranteed"].Value = xDep.SelectSingleNode("./Guaranteed").InnerText;
departure.Fields["Status"].Value = xDep.SelectSingleNode("./Status").InnerText;
departure.Fields["Currency"].Value = ConvertLanguageToCurrency(language);
departure.Fields["Market"].Value = ConvertLanguageToMarket(language);
departure.Fields["TwinSharePrice"].Value = GetPrice(xDep, "twn", language);
departure.Fields["SinglePrice"].Value = GetPrice(xDep, "sgl", language);
if (!String.IsNullOrEmpty(ship))
departures.Fields["Ship"].Value = ship;
}
catch (Exception ex)
{
departure.Editing.CancelEdit();
log.Error(ex);
throw ex;
}
departure.Editing.EndEdit();
}
So, how do I get the field be picked up?
Thanks,
James.
Firstly do you see the field in the web database in the sitecore administration.
If you do the item has the fields, you then should check the template assigned on the item and double check that the field is actually called "ship" and check the case as ive seen this as an issue before.
Also check the security on the item and field just in case anyone changed anything.
Next try and get the data from the item but instead of using the field name, use the field ID.
Let me know how you go?
Chris
Sorry Chris, StackOverflow, and the others who looked at my questions. It was a stupid typo. It's even there in my question
departure.Fields["SinglePrice"].Value = GetPrice(xDep, "sgl", language);
if (!String.IsNullOrEmpty(ship))
departures.Fields["Ship"].Value = ship;
}
departure is the item I am working on, departures is the collection it belongs to... doh.
So what is the protocol here? Do I delete my question now because it isn't really going to help anyone code better?
James.
