![]() ![]() If the exception is not caught, a 404 HTTP response is automatically sent back to the user. You may also call the find method with an array of primary keys, which will return a collection of the matching records: ', 100)->firstOrFail() Instead of returning a collection of models, these methods return a single model instance: first() Think of each Eloquent model as a powerful query builder allowing you to fluently query the database table associated with the model. Of course, in addition to retrieving all of the records for a given table, you may also retrieve single records using find or first. Now, letâs get to the view file- // you have created a Eloquent model and its associated database table, you can start retrieving data from your database. Then we pass the retrieved data through a compact function. In this UserController, we simply call the User model, and with the find(1) method we can get all the data of the user whose id is 1. Return view('User.view', compact('data')) By using that we can get the address of a specific user. In the User.php model, the getUserAddress() defines the User model has one relation with the Address model. We can create an address() model and under the User, model call the hasOne() method to relate the Address model. ![]() Here the user_id field is the id from the user table which will be used as a foreign key. #Eloquent laravel passwordIn this user table, we have some fields like id, name, email, password and in the address table, weâve id, user address, and the user_id field. Letâs see a simple diagram to understand it better. For example, a User model wants to be connected with an Address model. One to one relationship is one of the basic relationships. To run the development server, the PHP artisan command is- php artisan serve Weâre going to run the development server after every relationship example. v-model property is always automatically synced with visible state and you can show/hide using v-model.Here, the view() function returns a blade file that is stored under the User folder. Inside the controller, weâll need a function called view to display the data. Weâre going to use the name UserController. You can use the php artisan command to create a controller- php artisan make:controller UserController You can practice with different controllers if you want. In this tutorial, weâre going to use the same controller for all the examples. In your laravel project, they are stored in the app/Http/Controllers directory. The controller is a class where we handle requests, implement logic. You can create a route like this- Route::get('/index',)Īfter creating the route, now we need a controller. In MVC architecture, âMâ stands for âModelâ.A Model is basically a way for querying data to and from the table in the database. Because our main concern is to learn all the eloquent relationships. In this tutorial, weâre going to use the same route for all the examples. We need to create a route to view the database results. In our installed laravel project there is a file called web.php. In laravel routes makes a relationship with your laravel controller. You can name your project and database name as you want. env file on your laravel project and set up the database name. Right? Now the project is installed, we need to set up the database. To work with Eloquent ORM, obviously, weâre going to need a database. #Eloquent laravel downloadWith composer installed on your computer, you can download a laravel project with the following command- composer create-project laravel/laravel laravel-eloquent-relations Setup Database The following steps are-Ä«efore we start, we need to download and set up a laravel application. In this tutorial, youâre going to learn about eloquent relationships step by step with examples. In this tutorial, we will use Sublime Text 3 as a text editor, xampp server, and Google Chrome as a web browser. We can use the query builder also to handle the database process. ![]() To complete this tutorial all you need to have is a configured computer, a text editor, a web browser, a web server installed on your computers like Xampp or WampServer, composer(package manager), and a basic understanding of PHP and laravel. Conclusion: In this whole tutorial, we discuss Laravelâs eloquent relationships. #Eloquent laravel seriesEloquent maintains these relationships very easily through a series of common relationships. Database records or we better know them as tables are often related to each other. It handles database operations by representing data as objects. Before we start weâve to understand, what ORM means. Eloquent ORM is one of the most exciting and powerful built-in features in Laravel. ![]()
