Hi all,
Just getting familiar with rails and am performing some checks in a method within a controller. If the checks fail, I would like to indicate to the user a custom error message and stop the update (the method is updating a record in the model).
What are best practices to do this? I understand that for form validation I should be putting validation checks in the model however this is different in that the check is not against any one field in the model. Should I be raising an exception?
Ideally, I would like to indicate the error to the user in a similar fashion as when a form validation fails.
Thanks!
