How do I use seed data commands in Rails?

In Rails, you can use the db:seed command to load seed data from the db/seeds.rb file. This file contains the data you want to populate your database with.

Can you show me an example of what the seeds.rb file looks like?

Sure! A simple seeds.rb file might look like this:

User.create([{ name: 'Alice' }, { name: 'Bob' }])
Post.create([{ title: 'First Post', user_id: 1 }, { title: 'Second Post', user_id: 2 }])

How do I run the seed command?

You can run the seed command by executing rails db:seed in your terminal. This will populate your database with the data defined in seeds.rb.

What if I want to reset the database before seeding?

You can reset the database by running rails db:reset, which drops the database, creates it again, and then runs the seeds.
