Add support for model keys cast to backed enums in FormatModel

[saadsidqui]

• Telescope Version: 4.10.2
• Laravel Version: 9.x.x
• PHP Version: 8.1.13
• Database Driver & Version:

Description:

In Laravel\Telescope\FormatModel.php, an Eloquent model key can be cast to a backed enum, which would not be able to be cast to a string.

Steps To Reproduce:

1. Create a model with a non-autoincrement id.
2. Add a cast for id to a backed enum in the $casts member variable in said model
3. Try inserting a new row of said model into the database using create or updateOrCreate etc ...

I have submitted a rough fix in a PR#1286, but I'm not too sure that will help as I don't have the full picture.

Thanks. Seems like you already sent in a PR so let's see how it goes. This also seems like a feature request, not a bug.

Thank you. It is indeed a bug and not a feature request. Laravel added support for casting model fields to backed enums, and that breaks Telescope. This in my case broke my seeders and halted development (for a while before I dug into the code and patched it locally).

The PR submitted is just a quick fix I'm using locally.
