Seeding with unique objects

I'm trying to seed my database with project with unique project name, however my seeder does not work as I intended.

Seed.rb

users = User.order(:created_at).take(6)
50.times do |n|
name = "project-#{n+1}"
category = "category-#{n+1}"
users.each { |user| user.projects.create!(name: name, category: category) }
end

If I remove validates :name, presence: true, uniqueness: true it will create 50 projects for each user from 1 to 50, but then for the next user would do the same (count resets) and will create projects with titles from 1 to 50 which interferes with the validates rule.

Any ideas?

You can get last project_id and initial counter with it. Too user.id as additional scope.

last_id = Project.last.try(:id) || 1
50.times do |n|
  name = "project-#{last_id+n}"
  category = "category-#{last_id+n}"
  users.each do |user| 
    user.projects.create!(name: ("#{name}-#{user.id}"), category: ("#{category}-#{user.id}")) 
  end
end

Too you can add rand, Time.now.to_f.to_s, SecureRandom.hex(5)
