Queques > uniqueFor, add support for it being a method

[gmartinez]

Hi there, first time here so I hope this is the right place to bring this to the table.

First off; using Laravel 8.68.x

While implementing the uniqueFor feature in a job, for which documentation states "To accomplish this, you may define uniqueId and uniqueFor properties or methods on your job class..." I found that actually uniqueFor can only be a property as per the piece of code that acquires the lock at Illuminate\Bus\UniqueLock::acquire

So I guess either correct the documentation or better actually implement the feature which seems to be kind of low hanging fruit.

Gonzalo.
