How to start a Ruby on Rails project?

Starting a Ruby on Rails project may seem challenging at first, but with the right preparation, any developer can master this process. Here I'll walk you through the most important aspects of setting up a basic task management system. We'll start with project creation and the essential setup.

How do I create a new project in Rails?

To get started, open your command console and navigate to the directory where you plan to save your new project. In this case, we will use a previously created directory called coding/platzi. The instruction to create a new project is:

rails new organizer --skip-test --database=postgresql

• organizer: It is the name of the new project.
• --skip-test: Avoid setting up automated tests for now.
• --database=postgresql: Configures PostgreSQL as our database instead of the default SQLite.

What happens when I run the create command?

This command sets up a base directory and file structure for our Rails project. In addition, Rails will take care of installing the libraries needed for the project to work, including the pg library that allows the interaction between ActiveRecord and PostgreSQL.

How do I prepare the frontend of the project?

Once your project is set up, we can improve the appearance of the frontend using popular JavaScript and CSS libraries. We will use the YARN package manager to install:

• Bootstrap: Improve the GUI.
• jQuery and Popper: Bootstrap dependencies.
• Fonts de Roboto: Optimizes the typographic fonts.

The installation of these libraries is done with the following command in the console:

yarn add bootstrap jquery popper.js

How to configure the project's gemfile?

After integrating the JavaScript libraries, we focus on the Gemfile, which manages the gems of our Ruby on Rails project. Use the text editor to modify it. We include essential gems such as:

• Hamlet: templating system for Rails.
• SimpleForm: Optimizes the creation of forms.
• Pry and PryDoc: Facilitates debugging.

Place these gems appropriately according to their environment:

• Hamlet Rails should be in the development environment.
• Pry and PryDoc are placed both in the development and test environment.

Finally, we install these gems with:

bundle install

And just like that, we are all set! From here, you can continue detailing the rest of your application, customizing functionalities and adjusting the design according to your needs. As you progress, you'll see that with each step in Ruby on Rails, you're one step closer to becoming a more experienced developer. Keep going!
