Is there a way to auto generate a seed data file and create seed data like what you would see in Laravel in below link?
Laravel Database Migrations & Seed
I've seen some timestamped files created under db folder of Rails on another app with timestamp which had seed data included.
What would be good approach to create this?
I suggest you to use the combination of Fabrication gem and Faker.
Fabrication allows you to write a pattern to build your objects and Faker gives you fake data like names, emails, phone numbers and so on.
This is how a fabricator looks like:
Fabricator(:user) do username { Faker::Internet.user_name } name { Faker::Name.first_name } surname { Faker::Name.last_name } password { "testtest" } password_confirmation { |attrs| attrs[:password] } end In your db/seed.rb you can use it like this:
50.times { Fabricate(:user) } You will get 50 fake users with random username and "testtest" password :)
If you're looking to create real seed data (for a lookup table of statuses for example) you can add something like the following to your db\seeds.rb file.
# Statuses # Will insert 5 rows in statuses table ['Not Started', 'In Progress', 'On Hold', 'Complete', 'Not Applicable'].each do |status| Status.find_or_create_by(status: status) end Then, from your console: $ rake db:seed
To create the data when running tests you can use: load "#{Rails.root}/db/seeds.rb"
Theres a fairly useful gem for seed data called Faker. It's somewhat limited in the type of random data it generates, but I find it quite useful for simple things such as names, addresses, etc.
Of course you have to put it in a loop and write the query to insert it into the DB yourself.
