Welcome to the next step in building our ToDo App using Ruby on Rails! In this lesson, we will recall the GET queries and set up methods to fetch all ToDo items and specific ToDo items by their ID. These operations are crucial for displaying the list of ToDos and viewing details about each item.

By the end of this lesson, you will learn how to:

1. Fetch all ToDo items from a service and display them in a list.
2. Retrieve a specific ToDo item by its ID and show detailed information about it.

Here's a quick look at the essential code you'll be working with:

app/controllers/todos_controller.rb

In app/services/todo_service.rb, we have:

The above code snippets show how we define controller actions to interact with our ToDo service.

Understanding how to set up GET queries is fundamental for any web application. These queries enable your app to read and display data effectively.

Imagine a ToDo list app that can list all tasks but can't display details of a specific task. That wouldn't be very useful, right? By learning to implement these GET queries, you will build the backbone of your ToDo app, making it functional and user-friendly.
