Sitecore Unicorn Exclude Fields


While you have a high functional developers team working on multiple Sitecore projects with same code base, it is very vital to keep the local development environment as stable and functional as possible and also keep PR short.

While achieving that stage, we came across one small issue which is intern made me to write a blog in my journal what you are reading now.

The Issue

While reviewing PRs, we observed, there is one Unicorn’s .yml file come as default to quite a few PRs. The change it has got was just few fields updated.

After quick initial investigation, found out that yml file is nothing but one of the Data Exchange Framework(DEF) batch processing item in Sitecore content tree under system node.

After bit more investigation, it turns out the sitecore’s schedule task is triggering that DEF batch process. But that raise another question, why that schduler task item is not coming as changed item list as it is also source controled using Unicorn.

The Resolution

Lets focus on the second question for now, as it has quite a quick and simple answer.

The \App_Config\Include\Unicorn\Unicorn.config has one section called <fieldFilter> which takes care of it. As few frequently value changing fields has already been excluded from being serialized (smart stuff Unicorn Developers).

That section is looking like below

<fieldFilter type="Rainbow.Filtering.ConfigurationFieldFilter, Rainbow" singleInstance="true">
					<exclude fieldID="{B1E16562-F3F9-4DDD-84CA-6E099950ECC0}" note="'Last run' field on Schedule template (used to register tasks)" />
					<exclude fieldID="{52807595-0F8F-4B20-8D2A-CB71D28C6103}" note="'__Owner' field on Standard Template" />
					<exclude fieldID="{8CDC337E-A112-42FB-BBB4-4143751E123F}" note="'__Revision' field on Standard Template" />
					<exclude fieldID="{D9CF14B1-FA16-4BA6-9288-E8A174D4D522}" note="'__Updated' field on Standard Template" />
					<exclude fieldID="{BADD9CF9-53E0-4D0C-BCC0-2D784C282F6A}" note="'__Updated by' field on Standard Template" />
					<exclude fieldID="{001DD393-96C5-490B-924A-B0F25CD9EFD8}" note="'__Lock' field on Standard Template" />
				</fieldFilter>

So now, for my initial issue to fix , I simply have to add a field I wanted to exclude form being serializedin to this fieldFilter section.

So, I created new patch configuration file (as best practice suggests) an try to patch my new exclude fields under the node <fieldFilter>. At first, I did add the config like following

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:environment="http://www.sitecore.net/xmlconfig/environment/">
	<sitecore role:require="Standalone or ContentManagement">
		<unicorn>
			<defaults>
				<!--
					The field filter can be used to ignore fields when comparing or serializing (i.e. don't write them to disk).
					Commonly, metadata fields such as Last Updated will be ignored to prevent SCM conflicts.
				-->
				<fieldFilter>
					<exclude patch:after="exclude[@fieldID='{001DD393-96C5-490B-924A-B0F25CD9EFD8}']" fieldID="{985BA535-0F3E-4DA8-A768-A469026DE9DB}" note="'RequestedAt' field of DEF's Pipeline Batch item" />
					<exclude patch:after="exclude[@fieldID='{001DD393-96C5-490B-924A-B0F25CD9EFD8}']" fieldID="{6A2B2CBB-4338-4814-A8A9-9FECBB90456A}" note="'LastRunFinished' field of DEF's Pipeline Batch item" />
					<exclude patch:after="exclude[@fieldID='{001DD393-96C5-490B-924A-B0F25CD9EFD8}']" fieldID="{2AA5C591-FF55-411D-96C0-978BB2C58B94}" note="'Log' field of DEF's Pipeline Batch item" />
				</fieldFilter>
			</defaults>
		</unicorn>
	</sitecore>
</configuration>

But this has weird patching when I see showconfig.appx. It actually replaces first three entries form the original xml…!!!???

I did ask God(google) and found that sitecore sometime does not patch correctly if proper attributes are not used. Someone suggest to use hint attribute to control the patching.

I did replace my patching config attribute note with the hint and eureka….!!!

This is the final configuration patch file looks like.

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:environment="http://www.sitecore.net/xmlconfig/environment/">
	<sitecore role:require="Standalone or ContentManagement">
		<unicorn>
			<defaults>
				<!--
					The field filter can be used to ignore fields when comparing or serializing (i.e. don't write them to disk).
					Commonly, metadata fields such as Last Updated will be ignored to prevent SCM conflicts.
				-->
				<fieldFilter>
					<exclude patch:after="exclude[@fieldID='{001DD393-96C5-490B-924A-B0F25CD9EFD8}']" fieldID="{985BA535-0F3E-4DA8-A768-A469026DE9DB}" hint="'RequestedAt' field of DEF's Pipeline Batch item" />
					<exclude patch:after="exclude[@fieldID='{001DD393-96C5-490B-924A-B0F25CD9EFD8}']" fieldID="{6A2B2CBB-4338-4814-A8A9-9FECBB90456A}" hint="'LastRunFinished' field of DEF's Pipeline Batch item" />
					<exclude patch:after="exclude[@fieldID='{001DD393-96C5-490B-924A-B0F25CD9EFD8}']" fieldID="{2AA5C591-FF55-411D-96C0-978BB2C58B94}" hint="'Log' field of DEF's Pipeline Batch item" />
				</fieldFilter>
			</defaults>
		</unicorn>
	</sitecore>
</configuration>

After this, Unicorn re-serialized the DEF pipeline batch items and happy days….!!!!

Note:

There is new feature “fieldTransforms” available in Unicorn 4.1 and later version but I have not able to get that working on my project setup. But, something worth exploring for next time.

DEF – Pipeline batch ribbon button issue


This is going to be a short blog for fixing issue I came across while working on custom pipeline creation and execution for Sitecore’s Data Exchange Framework(DEF or DxF).

The issue

While the Pipeline Batch item is selected, buttons on DATA EXCHANGE toolbar at top does not behave how they should.

Immediately after selecting pipeline item, I noticed all buttons in ribbon is visible and clickable. Secondly, clicking on Run Pipeline Batch Button does not works. I was neither starting execution of pipeline nor displaying any visible error messages. See below image for more details:

The fix

I started investigation and collecting events what could have done the damage. Found that before last deployment it was behaving the way it should be. Huuummm… that’s good hint, isn’t it? The last release just deployed files to CMS server. This is soothing to my ears as investment scope is drastically reduced to files. The content automatically gone out of equation.

To fix this, I tried install DEF SDK package first with just deploying file artifacts and skipping any content installation.

Unfortunately, that does not work ….!!! 😦

Next best bet is obvious and try to re-install the DEF framework package with deploying files only.

And that does the trick ….!!!! (Dance)

Update:

The file \App_Config\Sitecore\DataExchange\Sitecore.DataExchange.Local.config was missing. Placing this file from Package has actually fixed the issue.

Happy Data Sync and import using Sitecore Data Exchange Framework. 🙂
