An example of an AI chatbot conversation about seeding data in Rails migrations.
How do I seed data in a Rails migration?
To seed data in a Rails migration, you can use the create method within the up method of your migration.
Can you show me an example of that?
Sure! In your migration file, you can do something like this:
class AddSampleData < ActiveRecord::Migration[6.0]
def up
User.create(name: 'John Doe', email: '[email protected]')
end
def down
User.where(email: '[email protected]').destroy_all
end
end
What if I want to seed multiple records?
You can use an array of hashes to create multiple records at once. For example:
User.create([{ name: 'Jane Doe', email: '[email protected]' }, { name: 'Alice Smith', email: '[email protected]' }])
