That way I wouldn't repeated the code on every model I wanted to use UUIDs. ramsey/uuid is a PHP 5.4+ library for generating and working with RFC 4122. We hook into this event, and use the uuid() method provided by the Str class in Laravel.Ī while ago, people might have installed a package with Composer in order to generate a UUID but you can generate them easily using the uuid() method provided by the class.Įasy as that, you can use UUIDs in Laravel.Īs I final note, I'll usually have a PHP trait called UsesUuid where I'll have the logic above. This even is fired just before the record is actually stored in the database. In our boot method, we are listening for the creating Eloquent event.
It sounds like your problem is that you like using UUID() in MySQL but don't want to execute an extra query to figure out what the new UUID is. Lastly, the getKeyType method just specifies that the IDs on the table should be stored as strings. No, it's not possible to have PHP generate the exact same UUID() as MySQL because it's a (completely) random number. Remember we are using UUIDs so we set auto incrementing to false. The getIncrementing method is used by Eloquent to now if the IDs on the table are incrementing. The boot method is where we can hook into our model and listen for any Eloquent events. The function below is an example of generating V3 UUID in PHP. Create a Function to Generate V3 UUID in PHP The V3 UUID is a unique ID generated from an MD5 hashing of a namespace and given string.
