What will you learn in this Symfony and databases course?

Programming is constantly transforming, and in this Symfony course we will guide you through the world of databases with a precise and in-depth approach. Throughout this course, you will explore critical topics such as entities, table relationships, relationship types, initial or dummy data loads, and custom queries. While some of these areas may sound advanced, this course is designed to give you a solid and clear understanding, so that you master Symfony in the database area.

How to start the project setup in Symfony?

Starting a project in Symfony may seem challenging, but with the right steps, it becomes a simple and tidy task. Here I will show you how to do it from scratch.

Starting a new Symfony project

To create a new project in Symfony, follow these steps:

1. Open your terminal and go to the folder where you want to save your project, for example, Sites.
2. Run the command to create a new project:

   symfony new data

   This will generate a new project called "data".

Stand up the Symfony server

With your project created, the next step is to pull up the server to view your application in the browser:

cd datasymfony serve

Once the server is up and running, you will be able to see the address to access in your browser. This will verify that your project is correctly configured.

Installing additional components for configuration

To facilitate the creation of entities and other elements in Symfony, it is essential to install the Maker Bundle. Use the following command:

composer require symfony/maker-bundle --dev

After this installation, you will have new tools that will simplify the creation of entities, controllers and more.

Database configuration

To connect Symfony with the database, follow the steps below:

1. Edit the .env file in the root of your project.

2. Configure the database by selecting the correct driver (in this case, MariaDB) and setting the connection parameters. For example:

   DATABASE_URL="mysql://usuario:contraseñ[email protected]:3306/datos"

3. If you are using MariaDB, verify the version by running:

   mariadb --version

4. To create the database, use the command:

   php bin/console doctrine:database:create

If everything is set up correctly, you will see a message confirming the successful creation of the database.

Validating the installation and connection

You have now installed the necessary components and configured the database connection. Make sure that everything is working by reviewing the installation commands and that the database is functioning as intended. Perform tests to ensure that the initial configuration is correct and ready to support application development.

With these items done, you have a solid foundation to move forward in your Symfony learning. We are here to accompany you on this educational journey, so keep exploring and learning!
