Drupal Migrations (V): Debugging Migrations-II

Mon, 27 Jul 2020 00:00:00 +0000

Following the previous post, in this article I wanted to share again some guidelines for debugging Drupal Migrations. While in the last article I wrote down some questions about modules, plugins and configuration object management, in this case I felt like stopping at something more “code-oriented”, more specific. I have chosen for this article some guidelines to configure Xdebug in an IDE (in this case I have used PhpStorm) for migrations running in a locally deployed Drupal using DDEV. With the aim of debugging a Migration process -although actually the process is similar for any …

Drupal Migrations (IV): Debugging Migrations-I

Mon, 29 Jun 2020 00:00:00 +0000

The Drupal migrations, despite their linearity in terms of definitions, contain a lot of inherited complexity. The reason is very intuitive: although the Migrate API is a supersystem that offers a very simple “interface” of interactions for the user-developer who wants to build migration processes, in reality several subsystems work by interacting with each other throughout a migration process: Entities, Database, Plugins…There are a lot of classes involved in even the simplest migration process. If we add the irrefutable fact that a migration will tend to generate errors in …

The systems and subsystems related to Drupal’s migration API are certainly exciting. In the previous articles in this series, I wanted to draw as complete a map as possible (part one) of the vast amount of resources, possibilities and referenced experts. In the second part I wanted to expose some basic mechanics of the migration processes in Drupal and knowing that this opens the door to thousands of options, possibilities and techniques….I didn’t want to let a third article go by without sharing some experiences migrating data from a common format as a Google Spreadsheet, …

Drupal Migrations (II): Examples

Tue, 17 Mar 2020 00:00:00 +0000

As I said in the previous post, during these months I will be playing with migrations and preparing a few cases for a future book, I hope. During these days of confinement, I want to keep publishing small articles here to share migration-related experiences.

In the previous post, I wrote about Drupal migrations from a toolbox point of view: a set of basic resources to help frame a migration.

There is a lot of information to process, and of course there are more concepts, techniques, and tactics involved in solving a migration. So this month I want to write something that lets me play with …

Drupal Migrations (I): Basic Resources

Tue, 25 Feb 2020 00:00:00 +0000

I am working on notes for a draft that should become a book about migration processes built with Drupal and its Migrate API. It is expected to be released in June 2020, and collecting, testing, and shaping the content has become quite a large piece of work.

There are still a few months left before launch, so, to preserve a little mental health and give these tasks some partial meaning, I thought I could publish a few small posts here, based on those working notes.

That way I can share something useful alongside the complementary notes and, if COVID-19 gets me before the book comes out, at …
