Since in default the Laravel installations have a users table already we will just skip it and run the migration for our user_contact_infos table. Since relationships also serve as powerful query builders, defining relationships as methods provides powerful method chaining and querying capabilities. To start we need to create first our tables for our one-to-one relationship using Laravel eloquent. Eloquent relationships are defined as methods on your Eloquent model classes. In this example, we will use the users table and user_contact_infos table and these tables are connected which the user has a user contact info with the use of user_id key inside user_contact_infos table. I will show you an example that is easy to understand and may help you in your future projects on Laravel. Here we will teach you, laravel methods hasOne (), hasMany (), belongsTo (), belongsToMany. That, or run a join first and order by urlstatus.createdat, DESC. Might make more sense to query UrlStatus directly, with latest, and attach Url instead. You can create methods in your Eloquent model classes. Querying for multiple Url models first and attaching each's UrlStatus models won't really get you the latest UrlStatus models per-say. If you're new to Laravel this tutorial is for you. Laravel Eloquent Relationships This tutorial will teach you how to create and use eloquent relationships in laravel applications. One-to-one model relation in Laravel is the basic relationship that we usually encounter when doing the Laravel project. It was a cold, wet night in Eloquent city. If you're looking for material on the latest version of Laravel, then please check out Code Smart. In this tutorial, you will learn to implement the Laravel 8 one to one relationship. Code Bright: Eloquent Relationships Back to Index This title was written for Laravel version 4. In this example, you could easily gather all blog posts for a given country. Example company->ordersArea () ->with ('localization') ->first () Alternatively, you can add the protected with 'localization' to your OrdersArea model. For example, a Country model might have many Post models through an intermediate User model. So in this tutorial you can understand how to create has many through relationships with migration with a foreign key schema for one to many relationships. You can read more about this in the documentation: Eager Loading. As before, if you used a different column to related them, declare the foreign key as the second argument.Originally posted visit and download the sample code: 2 Answers Sorted by: 2 To load the Localization with the ordersArea () relation, you can use Eager loading. Inversely, if you wanted to get the user the device belongs to, Eloquent will attempt to match the user_id column on the device table to the id column on the user table. Return $this->hasOne('App\Device', 'foreign_key_here',) If you named your column to relate the models something else, you will need to pass that through as a second argument in the relation method. If you use the load in several places, you could consider refactoring the ->load('ordersArea.localization') to a function in Company model, for example loadOrderAreasLocalization(). If you did this, then you are set and nothing should have to be done. The names of the relationships almost never change though, so it should be fine. So if your user table has the id column, it assumes there will be a column on device table called user_id. To access the relations' properties from there, it is simplyĮloquent will assume the foreign key uses the Model name. When you dd($user), you should see the related models in the relations array attribute. $user = User::with('country', 'Device', 'Computer', 'Category')->get() In this tutorial I'll show you the basics of using Laravel Eloquent, so that you can start using Eloquent quickly. The Laravel Eloquent ORM is a way to interact with your database. If you only want one relations returned with the user, remove the others. Laravel Eloquent is one of Laravel's flagship features and one of the most notable things that distinguishes Laravel from other PHP frameworks. So in your case, it can be something like this. $model = Model::with('relatedModel', 'relatedModelTwo')->get()
