Accessors for non-primary-key UUID fields

[westphalen]

The HasBinaryUuid trait seems to forcefully convert the primary key to its text representation during toArray. Even if this was the wanted behavior, any other UUID fields are left on their own. For example, a "belongs to" scenario, where a user_id or user_uuid binary UUID exists, nothing is done to convert that field to text. That leads to unclear exceptions due to json_decode failing for the binary field.

For consistency, the primary key should probably not forcefully be converted to text. Instead we could add something like public $uuidFields = ['id', 'user_id']; to the models. A default value for $uuidFields could take care of the automatic conversion of the primary key, while the user may set $uuidFields = [] to disable that behavior.

Let's further discuss this in PR #35 👍

I guess this should be reopened since the PR was abandoned, and this would be a nice feature

No need, the PR is still open, and I will look further into it when there's time. Unfortunately, I don't think I'll be able to give it attention anytime soon, so if you're up for it: feel free to fork the existing PR and submit it new one.
