Docker Compose comes included by default with Docker Desktop for both Windows and MacOS systems, but Linux users need to install the Compose executable, following Step 1 of How To Install and Use Docker Compose on Ubuntu 20.04.

Docker Compose installed on your local machine or development server.

Windows and MacOS users need to install Docker Desktop instead. If you’re running Ubuntu 20.04, you can follow Steps 1 and 2 of How To Install and Use Docker on Ubuntu 20.04 to set it up.

Docker installed on your local machine or remote development server.Regardless of your base operating system, here’s what you’ll need to set up in order to get started:

#Eloquent orm series

PrerequisitesĪlthough the code shared throughout this series should work seamlessly across multiple environments and systems, the instructions explained here were tested within an Ubuntu 20.04 local system running Docker and Docker Compose. That tutorial explains how you can build the demo application that this series uses as a foundation from scratch. If you’d like an introduction to the Laravel framework, you can follow the guide on How To Build a Links Landing Page in Laravel. You’ll improve the application by adding new models and defining new relationships between them that will extend the current database structure. The demo consists of a single page application that shows a list of links or bookmarks. To practice the examples explained throughout the series, you’ll download a demo Laravel application and use the included Docker Compose setup to run a PHP development environment on containers. In this project-based series, you’ll learn how to make database queries and how to work with relationships in Laravel Eloquent.

#Eloquent orm software

An ORM is software that facilitates handling database records by representing data as objects, working as a layer of abstraction on top of the database engine used to store an application’s data.Įloquent facilitates the task of interacting with database tables, providing an object-oriented approach to inserting, updating, and deleting database records, while also providing a streamlined interface for executing complex SQL queries. This choice can be made on a per-table basis.Eloquent is an object relational mapper (ORM) that is included by default within the Laravel framework. Atomic operations often offer comparable integrity with higher performance.īecause MySQL Server supports both paradigms, you can decide whether your applications are best served by the speed of atomic operations or the use of transactional features. The other nontransactional storage engines in MySQL Server (such as MyISAM) follow a different paradigm for data integrity called “atomic operations.” In transactional terms, MyISAM tables effectively always operate in autocommit = 1 mode. For information about InnoDB differences from standard SQL with regard to treatment of transaction errors, see Section 14.2.11, “InnoDB Error Handling”.

MySQL Server (version 3.23-max and all versions 4.0 and above) supports transactions with the InnoDB and BDB transactional storage engines.

Quoting MySQL Transactions and Atomic Operations docs ( here): For some reason it is quite difficult to find this information anywhere, so I decided to post it here, as my issue, while related to Eloquent transactions, was exactly changing this.Īfter reading THIS stackoverflow answer, I realized my database tables were using MyISAM instead of InnoDB.įor transactions to work on Laravel (or anywhere else as it seems), it is required that your tables are set to use InnoDB
