Project Description

In this project, we’ll create a simple application that allows users to create groups among themselves. The users then get to split bills among the members of a group.

First, you will create the database model and associations between different tables. We’ll use Ecto associations. We will also update the associated records to track expenses and the amount owed by each group member.

Then, we’ll create controllers and templates to create a new group or add an expense to a specific group. We will develop skills to build applications in Elixir and Phoenix.
