How can I perform a data rollback in Rails?
In Rails, you can perform a data rollback using ActiveRecord transactions. You can wrap your database operations in a transaction block and call rollback if something goes wrong.
Can you show me an example of how to do that?
Sure! Here's a simple example:
ActiveRecord::Base.transaction do
# Your database operations here
raise ActiveRecord::Rollback if some_condition
end
What happens if I don't use transactions?
If you don't use transactions, any changes made to the database will be permanent, even if an error occurs later in your code.
