If you're interested in using this automatic validation pattern in your applications, I've created a small package that will can make it a bit easier to get started with. Thanks for reading! I'm super excited to write some more articles about strange patterns you can use in your Laravel applications. By that I mean the validation itself is hidden when looking at your controllers and other parts of your application, so when something goes wrong or you need to add a new validation rule, it might cause some headaches or digging to find out where it is all taking place. The final con that I'd like to mention is that this pattern will push all of your validation to the "bottom of the drawer". Remember though, this is an unconventional thing to do. This doesn't bother me much, but there will be some people who find this disgusting and some sort of anti-pattern. This means that something that happens in the database layer could have some effect on the HTTP layer of your application. Side effectsĪs mentioned a second ago, Laravel will pick up on the ValidationException and try to redirect the user back with some errors. GET /posts and POST /posts would be fine. If for whatever reason your previous location was the same as the route where validation is failing, you will probably get stuck an a redirect loop.īe sure to only use this auto-validation pattern on separate routes, i.e. You may already use Laravel Valet to serve your local PHP and Laravel sites. Herd includes everything you need to get started with Laravel development, including PHP (versions 7.4 up to 8.3 Alpha), nginx and dnsmasq. Since the Validator::validate() method throws a ValidationException when validation fails, Laravel will try to catch that exception and redirect back to the previous location. Herd is a blazing fast, native Laravel and PHP development environment for macOS. Forget about the boring stuff and enjoy the magic. This approach will mean you only have to do is in one place, just create your models as regular elsewhere. You won't need to go through all of your controllers / form requests and change them. As long as you know the name of the method (use some sort of interface if you want), your controller won't know anything about the rules present, just that it needs to do some sort of validation.Ī smaller point is that any changes to the rules will be applied everywhere. This is another point on top of my last one. Re-usabilityĮven if you didn't want to do the whole auto-validation thing, you could still place your rules on the model and use those elsewhere. Your model handles all of that and encapsulates it in a single place. Your controller no longer needs to do any validation or worry about what data is being validated. With this auto-validation pattern, that is easy enough to achieve. In Laravel, this means your model becomes a God class full of database knowledge, and your controllers simply call methods without knowing what columns are present and what data types they are. One common thing, especially in more domain-driven patterns, is ensuring that your HTTP layer knows as little as possible about your database. Now when the $post->toArray() call is made, the published_at column will be present and processed. Most Laravel developers have used model events at some point in their career. Have you ever considered removing that logic from your main request / response flow and holding the model accountable instead? If not, let me show you how it can be done and some of the pros and cons. You could even do it inside of your middleware if you really wanted to. You can do it inside of FormRequest objects or as part of your controller logic. If you used the insert or DB technique then you have to give the value for slug field also.In most applications validation logic is placed in standardised places. If you want to store multiple record in seeder use this method instead of insert because in my case I want to slug automatically created using spatie/laravel-sluggable pkg. So createMany operation look like this $insertMany = Pricing::create() Īnd it works for, you can give it a try too. Return $this->belongsTo(Service::class, "service_id", "id") Return $this->hasMany(AvailableService::class, "pricing_id", "id") Īnd the AvailableServiceMode look like this namespace App I have two models Pricing and AvailableService Model The Create many Method createMany is available on relationship check reference to this link and this documentation from laravel
