The is_unique() form validation works great if you're creating a new record of whatever, but I ran into a small issue while editing a record.
Lets say you're editing a person and want to the is_unique() on the SSN, the issue I ran into, is the SSN is already going to be there for the user you are editing, so it may be a good idea to allow the user to specify the current value in a format something like
table.column:value, then you can use some php and mysql to either ignore that value, or whatever you find suitable.
I know you can just add a new validation check, or edit an existing one, which is what I did here, but I just thought this might be a good feature for CI4
Or.. is there already a feature for this that I totally skipped over, and no one pointed out in the thread I referenced?
