Laravel - Table with foreign key not working --Updated - php

Question

I'm using Laravel 5.2 and MySQL.
I'm developing a project to get used to Laravel. My project is a phonebook, where you can store contact info on a table. But to do this, you need to be logged in the system, which I made using the make:auth command. Simplicity, it seems.
In my "Users" table I have the field ID. This table is used to store the user info so they can login and access the contact stuff.
In my "Contacts" table, which is where I store my contacts, is a column named "Created By" that is supposed to take the field ID from the users table, just to reference who was the creator of said contact.
But here is the thing:
The contacts table isn't migrating, it doesn't matter what I do.
I already dropped both tables and made them from scratch, the USERS first, because it has the referenced primary key, and then the CONTACTS, with the foreign field set. I even dropped my models and created them using the same order above, because who knows what might work.
Here is my migration files:
USERS MIGRATION
----- ... -----
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email', 191)->unique();
$table->string('password', 191);
$table->timestamp('updated_at');
$table->timestamp('created_at');
$table->rememberToken();
});
}
----- ... -----
As stated, the table has the ID field I am referencing in my other table.
CONTACTS MIGRATION
----- ... -----
public function up()
{
Schema::create('contacts', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id', false, true);
$table->foreign('user_id')->references('id')->on('users');
$table->string('image');
$table->string('name');
$table->string('lastname');
$table->string('email', 191)->unique();
$table->string('phone',191)->unique();
$table->string('address');
$table->string('description', 255);
});
----- ... -----
The field user_id references the id field in the table users, as stated. The second parameter is setting incrementing to false and the third is setting unsigned to true.
Even if I make the default style ($table->integer('user_id')->unsigned(); --- $table->foreign.....;), the migration isn't working.
I even made the foreign field in a separated schema from this main body, like so:
Schema::table('contacts', function($table) {
$table->foreign('user_id')->references('id')->on('users');
});
But even like this, the migration isn't working.
I really don't know what is happening.
This is my Contact Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Contact extends Model
{
// Getting the user associated with the contact
// which means, I hope,
// The user that created the contact entry in the table 'contacts'
public function user()
{
return $this->belongsTo('App\User');
}
// protected $table = 'contacts';
// not using an id field
// could this be the error?
// dunno
// isn't laravel making an automatic id field?
// dunno too
public $fillable = array('name', 'lastname', 'email', 'phone', 'address');
// public $foreign = ('user_id');
//added because of error at migration
public $timestamps = false;
}
This is my User Model
<?php
namespace App;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
// Putting it in simple terms
// Hopefully, this will return
// the many contacts that said user recorded in the 'contacts' table
public function contact()
{
return $this->hasMany('App\Contact');
}
// protected $table = 'users';
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
}
UPDATE
I just rolled back my migrations and use the migrate command again, and it worked this time.
I can register an user, so the auth::check works and I can see the view with the form to insert a contact in the CONTACTS table.
But when I click the button to save, I get the following error:
2/2
QueryException in Connection.php line 729:
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`phonebook`.`contacts`, CONSTRAINT `contacts_user_id_foreign` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`))
1/2
PDOException in Connection.php line 457:
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`phonebook`.`contacts`, CONSTRAINT `contacts_user_id_foreign` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`))
I still don't know what is going on.

Answer 1

These are some of the ways you can add a contact and attach the user. Since you solved the foreign key issue, i won't address that.
$user = \Auth::user();
$user->contact()->create([
'name' => $request->input('name'),
'lastname' => $request->input('lastname'),
'email' => $request->input('email'),
'phone' => $request->input('phone'),
'address' => $request->input('address')
]);
Or
\App\Contact::create([
'name' => $request->input('name'),
'lastname' => $request->input('lastname'),
'email' => $request->input('email'),
'phone' => $request->input('phone'),
'address' => $request->input('address'),
'user_id' => \Auth::id()
]);
Or
$contact = new \App\Contact;
$contact->name = $request->input('name');
$contact->lastname = $request->input('lastname');
$contact->email = $request->input('email');
$contact->phone = $request->input('phone');
$contact->address = $request->input('address');
$contact->user_id = \Auth::id();
$contact->save();
Also add user_id to the $fillable property when you mass assign the value (second option shown above).
