![]() ![]() With two attendance records saved, you can now iterate over the employee's attendance records within a view like you would any other collection. To assign an attendance record to an employee, you'll first create a new Attendance object and then save it through the Employee object, as demonstrated here: $john = Employee::find(245) Associating an Attendance Record with Employee Model With the relationships in defined, let's next review how to associate attendance with an employee. If you don't understand why we'd want to use the belongsTo relation here, please refer back to the earlier section, "Introducing to Laravel Belongs To Relation". You'll likely also want to define the opposite side of the relation within the Attendance model using the belongsTo method: belongsTo('App\Employee','empId','id') ![]() } Defining the Inverse of the One to Many Relation Please find the following code for my Employee and Attendance Models. I have already created and placed the Employee and Attendance Models in app Folder. In this post I am not going to show you how to create Database Table Migration or How to Create Model, If you want to learn about how to Create a Database Table by Laravel Migration and its associated models, Please follow my previous article in the following links for related topics,Ĭreating Foreign Key References in Laravel Migration Continue to Read to learn how this is implemented. I hope it helps.Database One-to-Many (also known as the Has Many) relationship occurs when there is a row in a parent db table that corresponds to many raw in a child table.For instance an employee can have multiple attendance records, therefore one employee is related to many attendance entries, meaning we'll need to relate the Employee and Attendance models using a One-to-Many relation. This relationship type is used throughout Laratime Demo Project, so in this section we'll dig deeper at some actual code used to power the system. ![]() $userContactInfo = User::find(1)->user_contact_info Now let's retrieve the records using Laravel one-to-one relationship. Step 4: Retrieve Laravel One to One Relationship $userContactInfo = UserContactInfo::find(1) If you have the same user contact info and want to use it by the other user then the code below will be applied. $user->user_contact_info()->save($userContactInfo) In this section, we will create users with user contact info to test our Laravel one-to-one relationship.Ĭreating user contact info. Step 3: Create Data on Laravel One to One Relationship Now we have already set up our Laravel one-to-one relationship models. It will automatically attempt to find a User model that has an id that matches the user_id column on the UserContactInfo model. belongsTo(User::class) Īs you can see we added user() a method with belongsTo() method. Here is the complete code below of our UserContactInfo model. Now let's create a UserContactInfo.php model. Return $this->hasOne(UserContactInfo::class) Īs you can see above we added the user_contact_info() method for hasOne() which is the name of our related model class. * Get the phone record associated with the user. * The attributes that should be hidden for serialization. Now let's set up our User.php a model since it is already included in the installation we don't need to run a command: $table->timestamp('email_verified_at')->nullable() Schema::dropIfExists('user_contact_infos') įor the sake of this tutorial I will show you also the code for users table migration: id() Run the following command: php artisan make:migration create_user_contact_infos_table 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. To start we need to create first our tables for our one-to-one relationship using Laravel eloquent. 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. If you're new to Laravel this tutorial is for you. One-to-one model relation in Laravel is the basic relationship that we usually encounter when doing the Laravel project.
