Item Bucket And Key Design Challenges.

The Item bucket has been introduced in 7.0 and later version of sitecore. From its inception either very few project must have implemented the concepts and must have realized the true benefits.

Real time case study:-

• Country /State/City Item bucket.. Locate stores , service centres
• Articles/blogs etc.

Key Design and Run time Challenges:

• Sync the Bucket when data is dynamic. It takes time and can impact the performance.
• Index and Bucket query for large data set is still the problem. Depends what is part of the index provider is it -Lucene or Solr.
• Sync Strategy of item bucketed collections. Bucket(Sync)
• The baseline for Bucketing with Index is difficult to achieve as stats varies based on infrastructure.
• Link providers to understand URL to support SEO.

Create Item Bucket.-For given example. CarTypeFolder and Car template. 

1. Select standard value item of Car Template and click check box bucketable.
2. Apply Rules under Settings- Buckets -Item Bucket Settings. For my example I chose rule Specific template- in this case its CarTypeFolder whereas its contain item Car Template is marked bucketable in standard field. Bucket applied on folder with based on ID.
3. Go to Content tree..select Folder that is part of CarTypefolder and go to configure and click on Bucket and Sync. For reference see the screenshot.

1. Set Car Standard Values =Bucketable

2. Set Rules as per CarTypeFolder template and based on ID -Folder structure

3. Go to content tree, Select Super Car which is part of CarTypeFolder. Go to ribbon Configure and select Bucket and sync.

Still to write about- Indexing with Item bucket Context Query and Implementation.

Custom Workflows in Sitecore

Purpose
Business workflow

• Content Author- Submit
• Content Reviewer-Approve/Reject 
• Final State -Approved.

Technical Workflow 

• State
• Command 
• Action and Validation Action.

Workflow Snapshot

How to create it?

1. Open Sitecore in desktop mode and go to content Editor Screen. Go to Workflows and create Workflow with State, Command and Action Template.
2. As per above workflow, create Draft State with Submit action. On Submit action select Data-> Next State Awaiting Approval.
3. Create Awaiting Approval State with Two command Approve and Reject. Under Approve create three action - Auto publish(Type String : Sitecore.Workflows.Simple.PublishAction, Sitecore.Kernel, Param: Deep=1). SyncCustomDb Action(Reference .net bin dll) and Validation Action to report error , warnings to business users.[Data->Type->Sitecore.Workflows.Simple.ValidatorsAction, Sitecore.Kernel]
4. What next, you tick mark.suppress comment if you want to do so.
5. Create final Approved State within Awaiting Approval state. For Final Approved state ensure to mark Final checkbox .
6. For Reject State select Next state to Draft state.

Template used

• State
• Action
• Command
• Validation Action

Important Library

• Sitecore.Workflows.Simple.ValidatorsAction, Sitecore.Kernel
• Sitecore.Workflows.Simple.PublishAction, Sitecore.Kernel

Publish Parameters

Publish action accepts 6 parameters:

1. "deep" - controls whether children of the current item will be published. Possible values: "1" - children of the current item will be published; all other values - children of the current item will not be published.
2. "related" - controls whether related items of the current item will be published. Possible values: "1" - related items of the current item will be published; all other values - related items of the current item will not be published.
3. "targets" - comma (,) separated list of database names that item will be published to. Note, that this parameter does not expect a list of publishing target names, it expects list of database names.
4. "alllanguages" - controls whether current item will be published in all languages that exist in source database. Possible values: "1" - current item will be published in all languages that exist in source database; all other values - code uses values of other parameters to determine languages in which current item will be published.
5. "languages" - comma (,) separated list of languages in which current item will be published.
6. "itemlanguage" - controls whether current item will be published in its current language. Possible values: "1" - current item will be published in its current language; "0" - current item will not be published in its current language; all other values - current item will published in its current language. Note that even if value of this parameter is "0", current item will still be published in its current language if current language of the item is in "languages" list.

Querystring parameter

deep=1&related=1&alllanguages=1

Custom Workflow Action: SyncCustomDB

Suppose you want to sync your sitecore CMS data with custom database for Ecommerce database products or promotions if your enterprise solution doesn't provide that. The approach can vary with respect to problem and business requirement.

Here is the quick implementation.

Create Library with Workflow Pipeline processor and create new process .This process requires workflowPipelineArgs

Assign this workflow to the page item and then when business user approves the sitecore content for given item -template the action event will be performed to sync custom database. These can be anything, we can even replace this with any functionality such email notification or anything that needs to be done in case of approve content.

Sitecore Querystring Param- Cheatsheat

Below are the list of querystring param that comes handy when we are in production deployment and wants to troubleshoot the deployment status in each and every sitecore delivery server. This is very useful querystring parameter at times where there are separate Content managed –Authoring server and several load balanced delivery server, these querystring helps in finding the various behaviour of page and act as troubleshooting tools. 

yes there are various ways to look for sitecore errors such as data folder logs, sitecore analyzer, IIS logs, event logs etc.

Sitecore MVC with Dynamic Placeholder

Introduction
This is demo project with Car example.

Technical Use Cases

• Dynamic Placeholder with configured pipeline.
• View Rendering and Controller Rendering 
• Static Placeholder
• Repository to create Sitecore.Mvc.Presentation.RenderingContext Context.

Sitecore Design Layer

• Layouts
• Placeholders
• Renderings
• Items
• Reference -Data collection

Sitecore MVC

• View- Layouts
• View- Container 
• View-TextImage
• View-Header
• View-Footer
• Controller- FooterController
• Controller- TextImageController
• Controller- HeaderController
• Repository for above Controller

Three column Dynamic Placeholder

@Html.Sitecore().DynamicPlaceholder("sub-content-three-column-content-left")
    

@Html.Sitecore().DynamicPlaceholder("sub-content-three-column-content-middle")
    

@Html.Sitecore().DynamicPlaceholder("sub-content-three-column-content-right")
    

Extend Sitecore MVC using SitecoreHelper Sitecorehelper to extend the @Html.Sitecore.Placeholder("")

namespace Demo.Sitecore.CarInfo.WebSite.Utility
{
    public static class SitecoreExtensions
    {
        public static HtmlString DynamicPlaceholder(this SitecoreHelper helper, string key)
        {
            Guid currentRenderingId = RenderingContext.Current.Rendering.UniqueId;
            return helper.Placeholder(string.Format("{0}#{1}", key, currentRenderingId.ToString()));
        }
    }
}

Ultimately this dynamic placeholder fetch the textimage for respective layouts from  TextImage Controller Rendering.

TextImageRender Repository

    {
        public TextImage GetTextImage()
        {
            var item = RenderingContext.Current.Rendering.Item;
            var textImage = new TextImage()
            {
                Title = new HtmlString(FieldRenderer.Render(item, "Title")),
                Image = new HtmlString(FieldRenderer.Render(item, "Image"))
            };
            return textImage;
        }
    }
}

TextImage Model

namespace Demo.Sitecore.CarInfo.WebSite.Models
{
    public class TextImage
    {
        public HtmlString Title         { get; set; }
        public HtmlString Description   { get; set; }
        public HtmlString Image         { get; set; }
    }
}

TextImage Controller

namespace Demo.Sitecore.CarInfo.WebSite.Controllers
{
    public class TextImageController : SitecoreController
    {
        public ActionResult TextImageDetail()
        {
            TextImageRepository repo = new TextImageRepository();
            return View(repo.GetTextImage());
        }
    }
}

Create Pipeline to Process DynamicPlaceholderRendering

namespace Demo.Sitecore.CarInfo.WebSite.Utility
{
    public class GetDynamicPlaceholderRenderings : GetAllowedRenderings
    {
        public new void Process(GetPlaceholderRenderingsArgs args)
        {
            Item placeholderItem;
            var placeholderKey = string.Join("/", args.PlaceholderKey.Split(new[] { "/" }, StringSplitOptions.RemoveEmptyEntries).Select(x => x.Split('#')[0]));

            using (new DeviceSwitcher(args.DeviceId, args.ContentDatabase))
                placeholderItem = Client.Page.GetPlaceholderItem(placeholderKey, args.ContentDatabase, args.LayoutDefinition);

            List list = null;
            if (placeholderItem != null)
            {
                args.HasPlaceholderSettings = true;
                bool allowedControlsSpecified;
                list = GetRenderings(placeholderItem, out allowedControlsSpecified);

                if (allowedControlsSpecified)
                    args.Options.ShowTree = false;
            }

            if (list == null)
                return;

            if (args.PlaceholderRenderings == null)
                args.PlaceholderRenderings = new List();

            args.PlaceholderRenderings.AddRange(list);
        }
    }

Sitecore Web API for Angularjs MVC integration

Problem Statement
What if there is CMS system hosted in DMZ server and there is no scope of adding any additional requirement due to some reason and still wants to use Sitecore CMS as an option to port content to your digital interface that can be Mobile or other touch screen device installed in stores. Here is the solution to do so.
Recently we did the same implementation and made Sitecore CMS as source system to give data to digital screens and native Iphone App.

Cloud and Sitecore CMS way.

1. Sitecore CMS hosted in DMZ corporate infrastructure. Expose api's to access required data.
2. There will be asp.net spa applicaiton developed using asp.net MVC +angularjs and hosted in cloud to consume this CMS system.

Technology

1. glass mapper 
2. sitecore CMS 7.2
3. asp.net web api

Sitecore CMS Items Implementation

We only going to have content hence i created just reference folder within sitecore structure as per screenshot. Remember to take item id GUID for category to lookup through glass mapper.

Create Website Content under reference. As this is not going to be website path page item.

Create Category page item with category template. Keep the Item ID -Guid for glass mapper mapping with object tree to fetch categories.

Template Category

Add content.

Asp.net Web Api Implementation

The sitecore data item will be consumed via glass mapper ORM and can be modelled to get through API controller.

Here is the snapshot of solution explorer

The reference of nuget glass mapper in include configuration. This helps in ORM with sitecore object mapping.

Create Web api Route with respect to Sitecore

using System.Net.Http.Formatting;

Don't be Surprise If your website breaks in IE9 ! Console.log

Don't be surprise if something start breaking up in IE9 after you go for big bang release and customer started complaining website is not working. The reason is pretty straight forward, javascript and client scripting is taking centre stage and all new browsers support them very much. Console.log is common script that most of the developer used to trace the flow of javascript. It happens they forgot to uncomment them while release to production. It is rare case when big enterprise application fails to ensure this is taken care.

Data Driven Subscription reports in SSRS, what can't be done in sitecore webform marketeers

Its a challenge when we fetch reports out of promotion held through webform markeeters. To our rescue is always a custom db options with custom forms with good security layer giving added advantage and flexibility to business users and end customer.

How it works?
You got loads of data and it takes lot of time to generate a report on demand. It simple design approach we make use of canned report or just allow subscription data driven reports based on user personalization.

This is something we coming up for our client and help them realize the benefits.

Thinking Redis cache stores key value pair just like any native .net code would do, is not just that. What we don't realize is that the cache can be distributed and centrally stored for multi server or webfarms. Not only cache management even session state management can be easily achieve using azure redis cache.

In theory we able to distribute load on server to certain extent to make it available to end users with better throughout ,low latency and easy data management.

1. Distributed caching
2. Centrally stored
3. Easy session management
4. Easy to clear and revisit cache expiry policy.

Known Issue: Predictive Search- Accessibility

UX and technical design specifications, framework and guideline must be lay out for predictive search.

The best example is google predictive search.

Now remember one thing we sometime create custom predictive search with UL/LI with div tag and predictive search text box.

Important to note here:-

Dropdownlist aka combo box default behaviour does have up and down arrow keys to navigate through list items but this behaviour needs to be constructed when we use div-UL-LI options.

So remember next time when you working on something like this do take care of input field with predictive search.

I've seen developer using ARIA
Role=Status
Role=ALert
Aria-live=assertive
Autocomplete="off"
aria-labelledby="typeahead"

The only problem with this tags are they do not have universal acceptance. They works in some device, OS , browsers etc. 

Known Issue: Accessibility -Select Picker Item behaviour in Iphone Voice over

The select html combo box behaviour in Iphone voice is causing problem with accessibility. It doesn't enable the focus on picker selection of IOS when we double tap to activate the picker control( Select Id= > Option in html.

Now this very well works out in IOS 8.0 and above. There is some defect in IOS 7.0 and higher version. Having said that , the focus and default behaviour of picker for voice over is still a problem.

1. Double tap does not set the focus on picker item values.
2. After picker item is selected focus never moves to next element.


Bottom line is:-

Combo box aka dropdown box( select Option) must be customised to suit requirement.

Do add Label for at least for select .

 

Accessibility AA Tip and tricks

 

Accessibility:

·         Flow of information

·         Correct proof reading

·         Right colour contrast and text size to help users with visual problems

·         Right tabbing , focus and click ordering. Logical arrangement of information’s. Right speech, right flow of speech with correct pause. Simple example.. Go Slow, work is in progress. Well what if speak tool reads out in this way. Go pause, slow work is in progress. There should be balance of proper read out in very meaningful way. Instruction text and design has to be considered while accessibility is taken care. Content author must be trained to understand such implications with good examples.

 

§  Visually – Colour medium to communicate

 

o   Problem statement- The color Red with Arrow indicates you are here in this section whereas grey without bottom arrow indicates there are sub menu item to be viewed.

 

·         List of headings

 

·         Headings structure and hierarchy

 

·         Logical orders of tabbing

 

·         Skip Links back to top

 

·         Text size 200% in IE Or Zoom

 

·         Colour Contrast and Text size

 

·         Progress Bar- Such as you completed 1 of 3 step

 

·         Avoid abbreviation like Q&A , FAQ

§  FAQ read as Fack and so on.

 

·         Reading out numbers , units etc

§  Take care MB, cents, Dollar, KB, telephone number, credit card sample numbers etc.

 

·         Button should be informative.

§  Submit button and Review Button. If there are case where text on a button is very generic in nature such as continue, Read more, Add, More information,View . We can make information more elaborate for visually challenged users.

§  For e.g what do you mean by more information, related to what . These are the questions that may be reviewed and assessed.

§  Role=button

 

·         Anchor tag

§  Target=_blank its important to add explicit Opens in new window. If there is link with download, mention what is going to be downloaded like PDF, word doc and so on

§  Ensure we have role=button, role=link appropriately marked in anchor tag for IOS, android to call it as interactive element

§  Ensure href got some value. Href=”#!”

 

·         Call out table structure properly

·         Most used ARIA tags

§  Aria-hidden

§  Aria-label

 

Some handy Jquery To set focus

$('select').on('change', function () { $(this).next().focus(); });

 

For Empty Alt text attribute

 

//empty image alt tags

$("img").each(function (index) {

    $('.ccs1).attr('alt', "");

    $('.ccs2').attr('alt', "");

    $('.ccs3').attr('alt', "");

});
