How to ensure that a relation in a relation manager has at least one entry ?
App:
Laravel 12
Filament v3
I got these models :
- order
- orderlines
order hasMany orderlines
orderlines belongsTo order
on the OrderResource I got a relation manager.
When an order is updated (only) I'd like to check if at least one orderlines belongsto order. If not, i'd like to display a modal that halts the process.
I checked the documentation regarding lifecycle hooks butI don't get where to place this logic.
How would I proceed ? Thx !!

That doesn't make sense really, since you shouldn't be able to add to the relation manager until you have created and it sounds too late to be creating?
Why not use a table repeater like #awcodes-table-repeater and have this in a wizard or second step so the creation all happens in one and set min(1) an required on the repeater?
I'm not sure to understand why it doesn't make sense. Maybe i didn't give enough context.
The order creation is initiated from a widget that triggers a modal where I only have the 3 required field to create an order.
At this stage I do not have any relation manager displayed.
After this modal, i redirect the user to the edit page of the order where there is an orderline relation manager.
It's when the user save the order form that I want to check if the orderline relation manager is empty or not.
(That's why I want to validate the form on the update only).
I don't get this at all tbh... If you have the 3 fields, why not just click next in a wizard, use the data from what was input and fill out the orderlines?
But yes, you can still do it that way if you want to allow submitting a form, without the table repeater by setting the table repeater to ->visibleOn('edit')
Thx for trying to help, and sorry but I don't want to change the current setup. Relation manager is a must.
Here some screens to better demonstrate what I'm trying to achieve :
Ok... then add a custom rule which checks the relation count on another field I suppose
