I recently created a migration using ecto which looked something like this:
defmodule MyApp.Repo.Migrations.AddDateOfBirthToUsers do use Ecto.Migration def change do alter table("users") do add(:date_of_birth, :date, null: true, comment: "Send the user flowers on birthday." ) end end end
The file was named 20201208164822_add_date_of_birth_to_users.exs
The file went through some code reviews and eventually the name of the field was changed to
first_day_on_earth. The code was finally merged and deployed using CI/CD pipelines and is in production now.
However, I then realized that I could have changed the file name and the auto generated module name to better reflect the code changes in the review process.
My question is - how do I change or update the module name and the name of the migration file? What will be the cleanest way to to do this? Does it even matter?
