XML-D8 Migration: Extending the migration capabilities by using CUSTOM Process plugin

In our last blog post, XML-D8 Migration: Extending the migration capabilities by using available Process plugins, we have extended the migration capabilities by using already available process plugins. In this blog post, we will extend the capabilities of that migration by writing custom Process plugins.


In this blog post, we will map the content to different content types based on the 'site url' field in XML. There are no changes in XML file and we are using the same XML file which was used in earlier blog posts.


To use the custom plugin, we need to specify the plugin name in our .yml file under config/install, so we have made that one change which looks below,



Basically we are telling the migration API that for 'type' field use 'content_type_plugin' and 'site_url' XML field will be used as source.


Next we have created the custom process plugin in src/Plugin/migrate/process/ContentTypePlugin.php. This custom process plugin uses 'site_url' XML field to determine the content type (article or basic page) based on the requirements. Custom process plugin needs to be placed under /src/Plugin/migrate/process/ as per the Drupal PSR-4 standards. The plugins in Drupal 8 uses Annotations to define the name of the plugin. Our custom plugin looks like below,

https://github.com/amitgoyal/migrate_xml_d8_custom/blob/master/src/Plugin/migrate/process/ContentTypePlugin.php

After creating the custom process plugin and using it in our migration config .yml file, we need to clear the cache and re-install the module. And finally we can execute the migration to migrate the XML data in Drupal content types (article, page).



The migration has been executed successfully and we got all the data on D8 site in different content types as expected. It looks like below,


The source code is also available on Git repository.

Similarly we can write more custom process plugins based on our requirements and use them to do custom migrations!

Simple Meditation

Set small goals, such as meditating for two minutes every morning. When that feels OK, up the time to 5, 10 or 20 minutes. 1) Find a comfortable seat - where you can sit up tall, either crosslegged on the floor or in a chair. Close your eyes or soften the gaze so you are not focusing on anything in particular. Place the hands with the palms down on the tops of the thighs. 2) Take a moment to notice the sensation of sitting - become aware of the ground or chair beneath you, and the parts of your body in contact with them. Now bring your focus to your hands, noticing the weight of them on the thighs, and the feel of the fabric of your clothes.  3) Now begin to notice how your breath feels in your body as you inhale and exhale. Make no effort to change the breath, simply let your natural breath flow in and out. 4) Aim to stay focussed on these sensations of the breath, but when you notice the mind wandering, acknowledge the thought, then come back to the breath again.  5) When yo...

Custom MySQL Database to Drupal 8 Migration

Image
There are thousands of websites which are using MySQL as database. If we need to migrate data from Websites, which are using MySQL database, to Drupal 8 then we can use this blog post as starting point. We have a sample MySQL Database 'mysql_custom_db' which contains two tables, users and pages. The data in 'users' table looks like below,   The data in 'pages' table looks like below, As all the fields in 'users' table, from source database, will map to User entity in Drupal 8 site so we don't need make any changes there. But as we are migrating 'pages' table data to 'Basic Page' content type in Drupal 8 site, so we need to create required fields in 'Basic Page' content type. We have created the fields in 'Basic Page' content type and it looks like below, In our migration, field mapping between source site (pages) and destination site (Basic Page' content type) is like below, city...
