[英]How do I restart the seeds.rb columns from zero?
In rails, how can i get the seeds.rb to restart counting from 0 every single time? 在Rails中,我如何才能使seeds.rb每次从0开始重新计数?
Currently when i re-run: rake db:seed, the autoincrement columns keep increasing higher and higher. 目前,当我重新运行:rake db:seed时,autoincrement列会越来越高。
May be you can use this 也许你可以用这个
table_name = 'xyz'
ActiveRecord::Base.connection.execute("TRUNCATE TABLE #{table_name}")
before seeding values in seed.rb 在seed.rb中播种值之前
