Populating database with faker - ruby-on-rails

Question

I want to populate the database with a number of stores and users, that each user corresponds to one store. The issue with the code below is that I get the error Validation failed: Email has already been taken.
namespace :db do
desc "Fill database with sample data"
task populate: :environment do
make_stores
make_users
end
end
def make_stores
50.times do
name = Faker::Company.name
manager = Faker::Name.name
address = Faker::Address.street_name
Store.create!(name: name,
manager: manager,
address: address)
end
end
def make_users
stores = Store.all(limit: 8)
99.times do |n|
first_name = Faker::Name.first_name
last_name = Faker::Name.last_name
email = "example-#{n+1}#example.org"
password = "password"
stores.each { |store| store.users.create!(first_name: first_name,
last_name: last_name,
email: email,
password: password,
password_confirmation: password) }
end
end

Answer 1

The problem is that you're setting the email variable before calling stores.each, so all 8 stores will get a user with the same email.
Do something like this instead:
def make_users
stores = Store.all(limit: 8)
99.times do |n|
password = "password"
stores.each do |store|
first_name = Faker::Name.first_name
last_name = Faker::Name.last_name
email = "#{store.name.parameterize}-#{n+1}#example.org"
store.users.create!(first_name: first_name,
last_name: last_name,
email: email,
password: password,
password_confirmation: password)
end
end
end
Now the first 8 users will have an email like (some-store-name)-1#example.org, next 8 will have (some-store-name)-2#example.org and so on.
