Alchemy plugin to download report from SDL WEB8


We all have came a across from a situation where we need to deploy/port CMS items from one environment to another for that we have Content porter but we need to manually identity(list of items which got created or modified after a certain date) items which we need to migrate.We used Bundle Schema to clubbed all the items at one location but that is again what if we missed any item and as a result content porting might failed due to some or the other dependency.

Here, is an Alchemy plugin which will allow you to download report from CMS based on date.I have used coreService,jQuery to build this plugin and a .ASPX page which is for popup.

This plugin will help you in migration as well where you need to identify items from across CMS.


Steps 
1.    Download the Developer pack from visual studio gallery Link.
2.    Alchemy version that I have used can be downloaded from Alchemy4Tridion link.
3.    Create a project selecting "Starter Plugin Project" template change the project name .
4.    Build the project and navigate to the generated .a4t file.
5.    Drag and drop the file in alchemy window.

Alchemy Plugin Installed.
Let go to CME,
Plugin is installed and ready for use
Let run the plugin and get some records form CM Database.
Custom Popup to Download data

Using Jquery Table searching you can filter the records as well. It will look for the text in all the columns.With the help of Jquery searching you can filter data based on date as well.

View ALL Structure Group and Pages name in CMS in English

In my current project we are using SDL WEB 8.1 and DXA 1.5 ,client come up with the new request and wants to read all the items in CMS in english only, In the current implementation we have multiple locales, changing the component title to english from other multilingual language title is not the big challenge but when its come to changing the SG and Page name to english for multilingual site is an issue, because we are using DXA default implementation to render Sitemap,Breadcrumb and Navigation.

Client Requirement:- Client wants to read name of all the items in CMS in english, for content editor point of view and at the same time we need to manage the Navigation,Sitemap and Breadcrumb for the multilingual website.

One solution is that,we write our own custom TBB and push the output ,but its a lengthy process and time taking as well.What I did is I made the changes in the existing TBB code and its working fine.

Let's have a look

  1. Approach I followed.
  2. Changes required in the existing TBB and in CMS.
  3. How to debug the TBB.
  4. How to upload the updated TBB in CMS.
  5. And some Pre-requisites. 
Approach I followed:- I decide to create a common metadata schema and have linked component attached in it for both page and structure group and will read component value in the Generate Sitemap TBB, we can always made code tweaks in the existing one.,rather than creating new TBB.

Changes required in the existing TBB and in CMS:- Create a common Metadata schema and add link component field assign it to Structure group and Page.Update linked component field(s) value.Then, we need to update the existing SitemapItemData.cs model and add new property project name Sdl.Web.DataModel. Next is go to the GenerateSiteMap.cs file you will find this file in project Sdl.Web.Tridion.Templates and populate the value by reading the Metadata returned by the Tridion.ContentManager for StructureGroup and Page type.

How to debug the TBB:- There is a complete article available on SDL docx on how to debug the TBB.

How to upload the updated TBB:- You need to use TcmUploadAssembly.exe to upload the TBB this will ask you DLL source,CMS url,Item folder location(tcmID),userId and Password.I have created a batch file for this.
TBB Upload

Pre-Requisites:- To build the TBB code you are required to add reference of following DLLs.

  1. Tridion.Common
  2. Tridion.ContentManager
  3. Tridion.ContentManager.Common
  4. Tridion.ContentManager.Publishing
  5. Tridion.ContentManager.Templating
  6. Tridion.ExternalContentLibrary
  7. Tridion.ExternalContentLibrary.V2
  8. Tridion.Logging
  9. Tridion.TopologyManager.Client
  10. Microsoft.OData.Client

Once all the above changes are done you have successfully updated the TBB and added new field in Navigation.JSON ,now we need to update the code at CD side in DXA.

You need to update the following files in order to read the new field.

  1. Update the Link Model at Sdl.Web.Common.Models
  2. Update the SitemapItem Model at Sdl.Web.Common.Models both are available in DXA framework .
  3. Now, we need to assign the value in the updated model go to CreateLink() method at Sdl.Web.Tridion Class name DefaultProvider.cs and assign the new property.
  4. Build your code and Run.
  5. Debug Breadcrumb.CHTML and TopNavigation.CHTML page you will have new field value in the model returned.

Generic Storage Extension Solution with ElasticSearch,MongoDB and SOLR

In my last couple of blogs we have discussed on how to extend storage capability of SDL WEB 8. Today we are going to create one common solution where we can decide out of the following which one we want to use as a extended storage medium by just updating the configuration file.This will give you the flexability to select the storage medium you wanted to enable.
  1. Elastic Search
  2. MongoDB
  3. SOLR 
  4. You can also use Custom DB.
Let's discuss what is storage extension?

Storage Extension :-Is the capability of using custom storage medium to store the data.When we publish the data it goes in to the BrokerDB or on FileSystem as per the setting but we can extend this functionality by using storage extension technique.

How we do that :-We need to override methods which published and un-published(create,update and remove) component presentation to the Broker DB and need to update the cd_storage_conf.xml file to inject your custom storage extension code.

Bypass Model dependency while indexing data in ElasticSearch

Based on the feedback given in SDL Web Dev Summit in Delhi,India.

This is in continuation of my previous blog where we have used ElasticSearch as storage while publishing components data is getting saved in it.

Earlier whenever we need to index any component we first need to create schema model,that creates model based dependency to bypass that we now Serialize the DCP (Dymanic Component preseatation)which is in XML format into JSON and Elastic Search .NET based NEST API has this capability to index JSON directly.

Now, we just need to allow the schema in Dynamic Component Template which we have created to index the data in ElasticSearch.

In NEST API we have used

         var json = @"{
    ""BookName"": ""Book1"",
    ""ISBN"": ""978-3-16-148410-0"",
    ""chapter"" : [
        {
            ""chapter_name"": ""Chapter1"",
            ""chapter_desc"": ""Before getting into computer programming, let us first                     understand computer programs and what they...""
        },
        {
            ""chapter_name"": ""Chapter2"",
            ""chapter_desc"": ""Today computer programs are being used in almost every field,               household, agriculture, medical, entertainment, defense..""
        },
        {
            ""chapter_name"": ""Chapter3"",
            ""chapter_desc"": ""MS Word, MS Excel, Adobe Photoshop, Internet Explorer,                     Chrome, etc., are...""
        },
        {
            ""chapter_name"": ""Chapter4"",
            ""chapter_desc"": ""Computer programs are being used to develop graphics and                   special effects in movie...""
        }
    ]
}";

var indexResponse = client.LowLevel.Index<string>("fromelasticstoweb8", "esnews", json);


And Link Resolver TBB is used to generate the Link e;g i have multimedia component attached ,when you published it will resolve the link below is the DCP XML.

Mircoservice over SDL WEB 8 Coreservice


Self Hosted REST Microservice using OWIN and ASP.NET Web API 2

Open Web Interface for .NET (OWIN) defines an abstraction between .NET web servers and web applications. OWIN decouples the web application from the server, which makes OWIN ideal for self-hosting a web application in your own process, outside of IIS.

ASP.NET Web API - CORS Support in ASP.NET Web API 2. Cross-origin resource sharing (CORS) is a World Wide Web Consortium (W3C) specification (commonly considered part of HTML5) that lets JavaScript overcome the same-origin policy security restriction imposed by browsers.

For more details on how to setup and create Microservice read it here.

This service is used to get the data from SDL WEB 8 CM Database

ElasticSearch Module in DXA


In my last two blogs we have discussed how to create components by consuming the data from Elasticsearch and then how to index data in Elasticsearch when publishing components.

Today,We are going to discuss and create Elasticsearch module in DXA which will have following features .DXA Modules allows us to extend its Functionality via creating new modules. Here we can create new modules which gives us flexibility & re-usability.

Features and Advantages :- 

  • Free text search .
  • Tag based filtering.
  • Lighting fast response powered by Elasticsearch.
  • Pagination and sorting based on fields.
  • Article detail page.

In order to use the Elasticsearch module we need to setup the storage extension and Elasticsearch which we already discussed in my previous blog here.
Once that is done using Elasticsearch module in DXA we can search the content from Elasticsearch and render on DXA based application .

Let's discuss the CMS part first.
Elasticsearch Module structure 


  1. Define module's folder structure
  2. DXA gives us predefined structure where we can keep all the building blocks of the module.
  3. For each new DXA module, we need to create a new folder in Modules Folder
  4. The name of folder is usually module name.

Next is creating the Schema and Component Templates. I have create dynamic components and index them in Elasticsearch and render on the DXA based web application.


  1. Publish all the dynamic components and index them in Elastic.
  2. Create new area in you DXA web Application.
    DXA Module
  3. We can call Elastic RESTFul API to get the data.
  4. Data will be returned in the form of JSON.
  5. Create model to deserialize the JSON.
  6. Let's search for the text SDL.
  7. Result can be further filtered based on tagging as well.
  8. Compare the search result with the data index in Elastic
    Elastic Search RESTFul API

ElasticSearch Integration 4 WEB 8


In my previous post we have discussed on how to create components by consuming data from Elastic Search.Today we are going to discuss how to index data in ElasticSearch when publishing components from WEB8.

To know more about the ElasticSearch advantages and how to setup please click here.

Steps to setup Storage extension and Generic Index service which will read data from and push in to the Elastic search.

  1. CMS setup
    • Copy and paste the templating building block (TBB) to a location on your SDL WEB 8 CM Server
    • Upload ESI4TIndexing.Templating.dll TBB to WEB 8 CMS using TcmUploadAssembly.exe
    • Create a Component Template with following attributes
      • Output Format – XML Fragment
      • Add GetComponentAsXML TBB ,Publish Binaries in Package, Link Resolver and Cleanup Template.
  2. Setup ElasticSearch
    • Download ES from here and unzip.
    • Run bin/elasticsearch (or bin\elasticsearch.bat on Windows).
    • Run http://localhost:9200.
    • Default Elasticsearch instance is up and running now.
    • With the help of Elasticsearch .NET high level client ,we can do all the CRUD operations in Elasticsearch.
  3. Setup Deployer service
    • Open the cd_storage_config.xml Storage Configuration file from the /bin/config folder and add following node under the Storages section:
      • <StorageBindings><Bundle src="CustomStorageDAOBundles.xml"/></StorageBindings>
    • Copy and paste CustomStorageConfig.xml file to change the value of following nodes
      • ServiceEndPoint - URL of the IndexService
      • TemplateIdToIndex - Tcm Id Of component Template which we have created in step 1 CMS setup. 
    • Copy the CustomStorageDAOBundles.xml XML file in the Content Delivery /bin/config folder
  4. ElasticSearch Index Service
    • Copy and paste ElasticSearch IndexService on your server host it in IIS 
    • I have used Strongly typed interface to Elasticsearch. Fluent and classic object initializer mappings of requests and responses. Uses and exposes Elasticsearch.Net
    • Run Install-Package NEST
    • Copy the configuration folder as well .
      • You can update the log files path from Logging.config inside the configuration folder
    • Update the path of configuration\logging.config file in web.config of index service
  5. Here, I have created a default index  fromelasticstoweb8 (should be in all lower case other-wise you will get the error Invalid request) and Type esnews.
  6. Once the data is indexed in the ES .
  7. REST service will return data in JSON format.
    • To get all the records http://localhost:9200/fromelasticstoweb8/_search?q=*:*
To test the index and search services
  1. Index service

    1. You can use fiddler for debugging 
    2. I have created a sample schema article
      1. title
      2. description
      3. imageurl
    3. Run index service on fiddler
      • http://localhost/Service1.svc/AddDocument
      • Input JSON which will generated by custom storage 
      • {"ServicePayload":{"DCP":"<esnews Title='About SDL WEB 8' Id='tcm:6-12273' xmlns:xlink='http://www.w3.org/1999/xlink' xmlns:tcm='http://www.tridion.com/ContentManager/5.0'><Title>About SDL WEB 8</Title><Description>SDL recently released the latest version of their web content management SDL WEB 8 an all-in-one global Web Experience Management solution</Description><shortTitle>About SDL WEB 8</shortTitle><authorName>SDL</authorName><Category>WEB 8</Category><relasedDate>2017-02-03T23:44:08.261+05:30</relasedDate><imageUrl>Images/SDL.png</imageUrl><publication Id='tcm:0-6-1' Title='400 Example Site'></publication></esnews>","LanguageInRequest":"en"}}Method Name: AddDocument
    4. Execute this request in Fidler and verify the results returned
    5. Check in ElasticSearchas well inside the collection\document which you have created and entered in the index service 
    6. Result as 0 for success and 1 for failure
      •  {"ResponseContext":{"EnvironmentContext":null,"FaultCollection":[]},"ServicePayload":{"ErrorMessage":"","Result":0}}
    7. Test this by publishing the Component as well 
    8. Log File Where Response Result :0 means successfully published and data is index in ElasticSearch.
  2. Search Service
    • To get all data http://localhost:9200/fromelasticstoweb8/_search?q=*:*
    • To get the data based on the title http://localhost:9200/fromelasticstoweb8/esnews/AVo8K0bDJVbTUFCj_OQW
  3. Here fromelasticstoweb8 is the node and esnews is type.
