Best place for handling

Hi all,

In my current L5.3 application, I need to set a booking fee based on the value of the price field. If the price is > 3500 then the booking fee will be 550, otherwise 330.

• An admin can change the booking fee manually, normal users don't have access to edit the booking fee field.
• An admin can set the booking fee manually, and a user can still edit the booking afterwards, so we don't want to re-compute the booking fees based on the price field.
• The price can be set to 0, or the is_free option field could be true. If the ticket is free there are no booking fees involved.

My options so far are:

• Handle it from the controller, which I don't want to since it's a large form. (just want to use request->all()) when saving.
• Use the setBookingFeeAttribute() on my model, but it feels dirty as I will need to access the data from my request (request()->price and request()->is_free).
• Override the all() method from the Form Request, which seems half decent but I'm not 100% happy with this solution.

Have I missed anything that could handle this use case nicely?

Cheers, Yohann
