What are some advanced techniques for seeding data in Rails?

In Rails, you can use techniques like Faker for generating realistic data, or create custom seed files for complex data relationships.

Can you give me an example of using Faker in a seed file?

Sure! You can add Faker to your Gemfile, then in your seeds.rb, you can do something like:

10.times do
  User.create(name: Faker::Name.name, email: Faker::Internet.email)
end

What if I need to seed data with associations?

You can create the parent records first, then use them to create associated records. For example:

10.times do
  post = Post.create(title: Faker::Book.title)
  3.times do
    post.comments.create(content: Faker::Lorem.sentence)
  end
end

Are there any best practices for organizing seed data?

Yes! It's best to keep your seed data organized by creating separate files for different models, and using methods to encapsulate logic.
