What is the best way to structure seed data in Rails?

In Rails, it's best to organize your seed data in a way that reflects your application's structure. You can use the db/seeds.rb file to create records for your models. It's also helpful to break down large datasets into smaller, manageable files.

Can you give me an example of how to structure the seeds file?

Sure! You can start by creating a db/seeds/users.rb file for user data. In seeds.rb, you can then call this file like so: load Rails.root.join('db/seeds/users.rb').

How do I ensure that the seed data is unique?

To ensure uniqueness, you can use the find_or_create_by method. This checks if a record exists before creating it, preventing duplicates.

What if I want to reset my database and reseed it?

You can run rails db:reset, which drops the database, recreates it, and loads the seeds. Just be cautious as this will delete all existing data.
