Create A New Mix Project

Create a new project in the projects folder called journal using the command line.

mix new journal --sup

Configure your mix project with Ecto by following the Ecto Getting Started guide.

Journal

Now that we have a mix project with Ecto, you will create a journal application.

You will be able to create many different journals. Each journal will have many entries.

classDiagram
class Journal {
  title: :string
  description: :text
  entries: [Entry]
}

class Entry {
  title: :string
  content: :text
  journal: Journal
}
