Using migrations to migrate data from one table into another
I have two models user and account linked with each other as following
account.rb belongs_to :user user.rb has_many :accounts
I want to move the data from column
users table into column
I think the following should do the job but my question is if there is a better way of doing this inside a migration file considering if there are thousands of records?
Account.find_each do |account| if account.user.present? account.update_columns(name: account.user.name, xyz: account.user.xyz) end end
Note: Once this migration will run I will remove the column
accounts table removing the relationship between the two modals.
