Truncate table(s) with rails console

Question

I have this testingdatabase which, by now, is stuffed with junk. Now I\'ve done a few Table.destroy_all commands in the rails console which deletes all records and dependencies

Answer 1

I used below code to truncate all tables

ActiveRecord::Base.establish_connection
ActiveRecord::Base.connection.tables.each do |table|
  next if table == 'schema_migrations'

  case ActiveRecord::Base.connection.adapter_name.downcase.to_sym
    when :mysql2 , :postgresql
      ActiveRecord::Base.connection.execute("TRUNCATE #{table}")
      ActiveRecord::Base.connection.execute("TRUNCATE #{table} RESTART IDENTITY")
    when :sqlite
      ActiveRecord::Base.connection.execute("DELETE FROM #{table}")
  end
end
