Faker Gem으로 데이터를 빠르게 시드하는 방법 ⚡️🏃🏻💨

This is a Ruby Gem and will only work for Ruby applications.

First, install the Ruby Faker Gem.

gem install faker

Once the gem has successfully installed, head over to the seeds.rb file, and require the gem at the top of the file.

require 'faker'

You're ready to go, all there's left to do is... Seed. That. Data.

In your seeds.rb file, go ahead and write a small script using the Faker gem.

# generate 10 users
10.each do
    username = Faker::Esport.player
    name = Faker::Name.unique.name
    profession = Faker::Job.title
    email = Faker::Internet.unique.email
    address = Faker::Address.full_address
    phone = Faker::PhoneNumber.unique.cell_phone
    User.create(username: username, name: name, email: email, profession: profession, address: address, phone: phone )
end

Once you've created a beautiful script containing all your lovely data, seed it! In your terminal run:

rails db:seed

You can check everything was seeded correctly by confirming your data is present within the rails console, or if you have your server up and running, you can check your routes.

Note: If no seed data shows up, see that you are meeting all validations in your model that may be prohibiting the data from being created in the first place.

There you have it! ✨Data✨

If you need to create data that there are not necessarily generators for, get creative with ones that already exist! As you can see in the example script provided above, there was no username generator, so the Esport generator with the .player method was used instead. Most of the generators provide multiple methods for various types of, as well as unique data.

Creating seed data can be a tedious task, but it doesn't have to be! The Faker gem is fantastic for fast, simple, and sometimes funny seed data.
