I created an admin panel using Laravel Filament and used the
unique() modifier on an input, but I was unable to save subsequent changes after creation because the resource wasn’t unique to itself (another resource with the same value already existed, which was itself).
unique() method comes with a way of ignoring certain models, which we can use to ignore itself.
That way, we’ll be able to save changes to a model without getting an error saying that a field is not unique.
Update your usage of the
unique() modifier to be like this:
+ ->unique(ignorable: fn ($record) => $record);
Now, the currently-being-edited model will be ignored when checking for uniqueness.
