​
Overview

The PersonalData model stores additional personal information for users in the NutriFit system. This data extends the base User model with demographics and contact information. Namespace: App\Models\PersonalData Extends: Illuminate\Database\Eloquent\Model Table: personal_data Note: PersonalData is automatically eager-loaded on the User model via $with = ['personalData'].

​
Fillable Attributes

​
user_id
integer
required
Foreign key to the User model (one-to-one relationship)
​
cedula
string
National identification number (e.g., “0401234567” for Ecuadorian CI)
​
phone
string
Contact phone number
​
address
string
Physical address
​
birth_date
date
Date of birth (cast to date)
​
gender
string
Gender identifier (e.g., “masculino”, “femenino”, “otro”)
​
profile_photo
string
Path to profile photo in storage (relative path, e.g., “profile-photos/abc123.jpg”)

​
Casts

The model automatically casts:
  • birth_date → date

​
Appended Attributes

The following computed attributes are automatically appended to JSON/array serialization:
  • age - Calculated from birth_date

​
Relationships

​
BelongsTo

​
user()
BelongsTo
Returns the user this personal data belongs to (User model)
$personalData->user->email; // Access the associated user

​
Accessor Methods

​
getAgeAttribute()

public function getAgeAttribute(): ?int
Calculates the user’s age in years based on their birth date. Returns: Age in years, or null if birth_date is not set. Usage: 
$user = User::find(1);
echo $user->personalData->age; // 28 (automatically calculated)

// Also available in JSON
$user->toArray();
// [
//   'personal_data' => [
//     'birth_date' => '1998-05-15',
//     'age' => 28,  // Automatically appended
//   ]
// ]
Implementation: Uses Carbon’s age property to calculate years between birth_date and today.

​
Usage Examples

​
Creating Personal Data

use App\Models\User;
use App\Models\PersonalData;

// Create user first
$user = User::create([
    'name' => 'María González',
    'email' => '[email protected]',
    'password' => bcrypt('password'),
    'role_id' => 3,
    'user_state_id' => 1,
]);

// Add personal data
$personalData = PersonalData::create([
    'user_id' => $user->id,
    'cedula' => '0401234567',
    'phone' => '0987654321',
    'address' => 'Av. Principal 123, Quito',
    'birth_date' => '1995-08-15',
    'gender' => 'femenino',
]);

​
Accessing Personal Data

// PersonalData is automatically loaded
$user = User::find(1);

// Access personal data directly (no additional query)
echo $user->personalData->phone;
echo $user->personalData->age; // Calculated automatically
echo $user->personalData->birth_date->format('d/m/Y'); // 15/08/1995

​
Uploading Profile Photo

use Illuminate\Support\Facades\Storage;

// Handle file upload
if ($request->hasFile('profile_photo')) {
    // Delete old photo if exists
    if ($user->personalData?->profile_photo) {
        Storage::disk('public')->delete($user->personalData->profile_photo);
    }
    
    // Store new photo
    $path = $request->file('profile_photo')->store('profile-photos', 'public');
    
    // Update personal data
    $user->personalData->update([
        'profile_photo' => $path,
    ]);
}

// Get profile photo URL using User helper method
$photoUrl = $user->profilePhotoUrl(); // Uses this PersonalData field

​
Updating Personal Data

$user = User::find(1);

// Update via relationship
$user->personalData->update([
    'phone' => '0991234567',
    'address' => 'Nueva dirección 456, Guayaquil',
]);

// Or find and update directly
PersonalData::where('user_id', $user->id)->update([
    'cedula' => '0409876543',
]);

​
Querying by Personal Data

// Find users by cedula
$user = User::whereHas('personalData', function ($query) use ($cedula) {
    $query->where('cedula', $cedula);
})->first();

// Find users within age range
$users = User::whereHas('personalData', function ($query) {
    $query->whereNotNull('birth_date')
          ->whereRaw('YEAR(CURDATE()) - YEAR(birth_date) BETWEEN 25 AND 35');
})->get();

// Get users with profile photos
$usersWithPhotos = User::whereHas('personalData', function ($query) {
    $query->whereNotNull('profile_photo');
})->get();

​
Validating Personal Data

// Validation rules example
$rules = [
    'cedula' => 'required|string|size:10|unique:personal_data,cedula,' . $user->id . ',user_id',
    'phone' => 'required|string|min:10|max:13',
    'address' => 'nullable|string|max:255',
    'birth_date' => 'required|date|before:today|after:1900-01-01',
    'gender' => 'required|in:masculino,femenino,otro',
    'profile_photo' => 'nullable|image|mimes:jpeg,png,jpg|max:2048',
];

$validated = $request->validate($rules);

​
Calculating Age-Based Metrics

$user = User::with('personalData')->find(1);
$age = $user->personalData->age;

// Age-based recommendations
if ($age < 18) {
    $caloricNeeds = 2000; // Adolescent
} elseif ($age < 65) {
    $caloricNeeds = 1800; // Adult
} else {
    $caloricNeeds = 1600; // Senior
}

// Check if user can register (age requirement)
if ($age < 18) {
    return back()->withErrors('Debe ser mayor de 18 años para registrarse.');
}

​
Displaying User Profile

$user = User::find(1);
$data = $user->personalData;

// Build profile display
$profile = [
    'name' => $user->name,
    'email' => $user->email,
    'initials' => $user->initials(),
    'photo_url' => $user->profilePhotoUrl(),
    'cedula' => $data->cedula,
    'phone' => $data->phone,
    'address' => $data->address,
    'age' => $data->age,
    'gender' => $data->gender,
    'birth_date' => $data->birth_date?->format('d/m/Y'),
];

​
Seeding Example

// In a seeder or factory
use App\Models\User;
use App\Models\PersonalData;

User::factory(50)->create()->each(function ($user) {
    PersonalData::create([
        'user_id' => $user->id,
        'cedula' => fake()->numerify('04########'),
        'phone' => fake()->numerify('09########'),
        'address' => fake()->address(),
        'birth_date' => fake()->dateTimeBetween('-65 years', '-18 years'),
        'gender' => fake()->randomElement(['masculino', 'femenino', 'otro']),
    ]);
});
