In this lesson we'll cover downloading and installing the Migrate module (version 7.x-2.6) and ensuring that our local environment is ready to be able to run migrations via both the UI and drush. Once that's setup we'll take a high level look at the migrate module's UI and drush commands to familiarize ourselves with the tools that we'll be using throughout the rest of the series. This will also help formalize some of concepts introduced in the previous lesson.

Introduction to Drush series
Drupalize.Me Migrate module series code on GitHub
This series is focused on using the Migrate module to import data that exists in various different sources into a Drupal 7 website. The Migrate module provides an extremely flexible and robust framework for accessing data from various sources and importing or migrating that data to Drupal. With built in support for creating core Drupal data types likes nodes, users, and taxonomy terms, the Migrate module is one of the best solutions available for importing content into Drupal.
This series kicks off with Joe Shindelar explaining the basic components that make up a data migration, and the terminology and code that is specific to the Migrate module. Then continues with a series of lessons that take you from installing the Migrate module to writing and running your own custom data migration.
Throughout the series Joe teaches us how to run a data migration using both the Migrate module's UI and drush, and some of the plusses and minuses of both methods. Joe also talks about the various different sources, or types of data, from which the Migrate module can read data and how to map the unique fields in a row of source data to their corresponding Drupal content types and fields.
By migrating from a single source into two different Drupal content types we'll also have the opportunity to learn about creating relationships during a migration and mapping the resulting information to an entity reference field. During the course of writing a custom migration Joe will show us how and where we can add code to perform additional runtime data munging during our import process. We'll learn about importing data into multi-value fields, and even providing defaults for fields that don't have information. Then we'll look at some of the tools the migrate module provides for collaborating with team members in order to create a successful migration path.
Finally we'll wrap up the series by looking at a couple of different techniques for debugging our migrations and dealing with pesky source material that just doesn't want to be imported.
Because this series is focused primarily on writing custom data migrations, and since the Migrate module itself requires at least some amount of code to be written to perform a migration, it is suggested that students be familiar with PHP and basic Object Oriented Programming techniques. Although not required to run a migration, Joe uses the drush command line tool extensively in this series. If you need a refresher on using drush take a moment to watch our drush series.

In this lesson we'll take a look at running migrations via drush rather than via the Migrate module's UI. We'll take a look at the commands provided by the Migrate module and talk about what they do. Then we'll practice running, rolling back, and otherwise interacting with migrations via drush commands. Throughout the lesson we'll learn about some of the functionality you get from running migrations via drush that are not provided by the UI, like the ability to specify a single record to migrate with the --idlist flag. Finally we'll learn about why in most cases drush is a better tool for running large data migrations because of the limitations imposed on the UI. Pay close attention to this lesson since throughout the remainder of this series we'll be running all of our migrations via drush.

In this lesson we'll take a more in-depth look at the migrate module's UI with a focus on being able to identify and execute custom migrations. For now we'll work with the provided example migrations just so that we have something to work with. Throughout the lesson we'll learn how to run a migration to import it's data into Drupal, rollback a migration that was previously run in order to set a clean slate, and other ways we can interact with a migration via the UI. Then we'll discuss some of the challenges inherit in running migrations via the UI and Drupal's Batch API and how to identify them.

When you’re uploading photos to a website, it’s important to ensure that they are displayed at the right size. Otherwise, when you upload an exceptionally large image, chances are good that it will break your site’s layout. To prevent this, you’ll want to scale these images so that they’re a consistent size, and create thumbnails for use in listing pages. Image styles are a feature that’s part of Drupal core’s Image module, and it provides these options and many more for displaying images. In this lesson we'll get an overview of the core image styles feature so that we understand how it works, which styles and effects we have to work with, and some tips for troubleshooting when your images don't display properly.

In this lesson, we take a look at our Band Wagon case study, and then we'll go through our implementation plan and see how we're going to tackle this one. In our case study, John and Lisa decide to make a website to share information about all the music they love, including videos, photos and reviews, and they want their friends have a voice on the site as well.
First of all, they need to be able to upload images to the site, and have an image that's small in one location but full-sized in other locations. We'll want to embed some videos, as well.
Their friends don't know how to write HTML, so we let them use a simple form to select media, and maybe reuse other people's images. We want to provide them with a WYSIWYG tool bar, an editor that helps them write HTML without coding.
How will this work? We'll use Drupal Core's Image Module and image styles, and expand the Media Module. For our WYSIWYG editor we're going to use the WYSIWYG Module, and then we're going to need to get an editor that we can plug into it.

In this lesson, we are going to see how the book relates to each of the series we have, and how each of the individual series are organized. We will end up with thirteen series to cover the entire book. Then we will take a look at how you should use the videos with the book. If you don't have the book, not to worry, as the book would only act as supplementary material to the video lessons. You don't need the book to successfully follow these series. If you do have the book however, we want to make sure you understand how the lessons and book relate to each other.

Using Drupal comes with source code intended to be used throughout the lessons to make following the lessons much easier. In this lesson we're going to take a look at what that source code provides for us, where we can get a copy of, and how to use it. We'll go through the installation process, as well as see how we can switch between chapters in the source code without destroying work you've done on previous chapters. It is important to note that using the source code is very important if you want the lessons to match what is in the lessons. Drupal modules can change a lot over time, and the source code is designed to exactly match what is covered in the lessons. Once you've learned the basics of a chapter by working through the source code, you can upgrade your modules and explore the differences in newer versions, with the base understanding you've gained from the lesson.
Warning: Since this Drupal code is several years old, you must use PHP 5.3. PHP 5.4 or higher will not work. You will need to make sure your server is using PHP 5.3 in order to use this code properly. Many all-in-one servers, like WAMP, MAMP, and XAMPP provide older versions of PHP and a way to switch back and forth between versions.

The Using Drupal series of lessons walks through the O'Reilly book, Using Drupal, written by Angie Byron, Addison Berry, and Bruno de Bondt. We use the second edition, which covers Drupal 7. The book starts off with taking a look at Drupal Core and then works through various case studies using a wide range of contributed modules from the Drupal project.
The video series follows along with what's in the book, so if you have the book, the videos are really great supplemental material. Even without the book, you’ll get the full lessons here in the videos.
This series is intended for people who have worked with the web and understand how a website gets delivered, and in particular, how to get a website onto a web server so that people can actually see it and use it. The rest of this introductory series we have here will look at how the book relates to the video series we're going to be creating, and how you can use those 2 together.

Once you have met all of the requirements and gathered the information you need, you can get down to the installation. This lesson assumes that you have already downloaded Drupal, placed the extracted files on your web server, and are able to create your database.

It’s not enough to just get Drupal installed; you also need to make sure to keep it up-to-date. New releases of modules and Drupal core come out periodically, most of which fix problems, some of which add new whiz-bang features, and some of which address critical security problems. In this lesson we will review Drupal version numbers and what they mean, review the core Update Status module, and then discuss using maintenance mode, and the update.php script.
Note: Not mentioned in the video is the fact that in addition to the user 1 account, you can also log in with any account that has the "administer software updates" permission enabled to run the update.php script.

Updating your site often sounds much scarier than the actual experience is. The most important step to remember is creating and testing backups of your site. In this lesson, we will create our backups, download a new version of Drupal core, and go through the process of updating our files and running the update.php script.
Note: Not mentioned in the video is the fact that in addition to the user 1 account, you can also log in with any account that has the "administer software updates" permission enabled to run the update.php script.

Drupal's contributed projects tend to move more quickly than Drupal core and there- fore require more updates within a Drupal version's life cycle. You can upgrade multiple modules at the same time, although it's best to do one at a time to reduce the chance of errors, and to allow you to isolate problems that might come up during an upgrade. In this lesson we will look at our Available Updates report, and use the Update Manager to upgrade a few of our contributed modules.

Prior to installing Drupal, it’s important to make sure that you can actually do so, and understand a bit about how Drupal is structured. The first lesson provides a checklist of Drupal’s requirements, and also highlights important things in the Drupal file structure that are worth knowing before diving into the installation process. We also explain and take a quick look at how you can use Drupal to run multiple sites from the code base, known in Drupal as a multisite installation.

What Is Drupal?
FreeTo learn more about how to get started with Drupal, also see our Introduction to Drupal guide.
In this lesson we take a look at Drupal, the open source Content Management System. We learn about the major components of a Drupal site and the library of constantly evolving tools available for working with Drupal. We find out how to see who uses it, by looking at DrupalShowcase.com and Drupal case studies on Drupal.org, among others. We look at Drupal's major features, such as Modules.
With this overview we have some context as we move forward into the series.

Before we jump into building our first Drupal 7 site, we should also take a look at the great resources you have out there to help you on your journey. Being an open source project, Drupal has an amazing community of people who have paved this road before you. In this lesson we're going to look at the free community resources that you can use to not only find answers to your questions, but also connect with thousands of people around the world who are working in the same space you are. -- We are going to take a tour of the communtiy documentation, various Drupal forums, project issue queues, where you can glean a lot of useful information and help, Internet Relay Chat, or IRC, for real-time collaboration, and getting in touch with user groups of like-minded people around the world.

In this lesson we're going to start building our site for Mom and Pop, Inc. We're starting off by working on our content, to get things filled out a little. First, we'll create an About Us page with the basic info for the store, like address and opening hours. Then we'll create our first article, which welcomes people to the new site, and see how the two core content types, Basic page and Article, are different from each other. Then we'll tweak our main navigation so our tabs display correctly, and finish things off by looking at block management. We'll remove the "Powered by Drupal" block and add a new block to the site for our weekly specials.
