9/23/2023 0 Comments Laravel eloquent find by id![]() we will help you to give an example of how to get data with multiple ids in laravel eloquent. The workaround is to get all results into Collection and then get the keys: $allPermissions = Permission::all()->modelKeys() īut it may cause performance issues if you're getting all records for big table. In this article, we will implement a laravel where multiple ids. $permissions = $role->permissions->pluck('id') īut in case of modelKeys(), this will fail with error "Call to undefined method App\Models\Permission::modelKeys()": $allPermissions = Permission::modelKeys() So method pluck() exists for both Model and Collection, so both would work: $allPermissions = Permission::pluck('id') This episode is sponsored by Honeybadger - combining error monitoring, uptime monitoring and check-in monitoring into a single, easy to use platform and making you a DevOps hero. protected primaryKey fooid the find() function will go through fooid instead of id. Tech News Jake and Michael discuss all the latest Laravel releases, tutorials, and happenings in the community. Notice that, as I said before, it works on Collections, not on just Laravel model. The find() method finds the Model by its primaryKey property. Official description of modelKeys() method is pretty short: "Get the array of primary keys." $permissionIDs = $role->permissions->modelKeys() $permissionIDs = $role->permissions->pluck('id') īut what if your auto-increment primary key name is not "id"? Apparently, you can get the key(s) from Laravel model, with method modelKeys() on Collection: // Same result as above. ![]() Typical code to do this will be with pluck() function: // returns array of IDs When invoking the user method, Eloquent will attempt to find a User model that has an id which matches the userid column on the Phone model. And then you need to get IDs of permission by a certain role. Imagine, that you have hasMany() relationship - one Role has many Permissions. I will show you two quick ways to do it - one is pretty popular, and another is a function which I found out only today. There are situations where you need to get array of IDs for some records in collection/table.
