Problem with seeding users to database in Laravel - php

Question

I am trying to seed users in database but I get error saying
Symfony\Component\Debug\Exception\FatalThrowableError : Call to a member function random() on bool
I have users table and genders table with gender_id in users table that points to Man or Woman column in genders table with hasMany relationship. I want to be able to write gender_id automatically in users table when I seed the database and create a new user. Currently with this code I get that error from above and NULL in gender_id column, but rest it inserts correctly in both users and genders table. When I remove random() function then it inserts always 1 in gender_id, but I want to be able to write 1 or 2 randomly. Also when I dump $genders it returns TRUE. Is there some way around this, any help is appreciated. Here is my code.
UserSeeder.php
<?php
use Carbon\Carbon;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Hash;
class UsersTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* #return void
*/
public function run()
{
$genders = DB::table('genders')->insert([
[
'genders' => 'Woman',
],
[
'genders' => 'Woman Looking For Woman',
],
[
'genders' => 'Man',
]
]);
//dd($genders);
DB::table('users')->insert([
'gender_id' => $genders->random(),
'name' => 'authuser',
'email' => 'authuser#auth.com',
'email_verified_at' => now(),
'password' => Hash::make('auth123456'),
'age' => 18,
'remember_token' => Str::random(10),
'created_at' => Carbon::now(),
'updated_at' => Carbon::now(),
]);
}
}
users table
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->unsignedBigInteger('gender_id')->nullable();
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password')->default();
$table->integer('age')->default()->nullable();
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}
genders table
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateGendersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('genders', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('genders');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('genders');
}
}
User.php
public function gender()
{
return $this->belongsTo(Gender::class, 'gender_id', 'id');
}
Gender.php
public function users()
{
return $this->hasMany(User::class, 'gender_id', 'id');
}

Answer 1

You can pluck your id values from Gendre and do randomly on that like this:
$genders = DB::table('genders')->insert([
['genders' => 'Woman'],
['genders' => 'Woman Looking For Woman'],
['genders' => 'Man']
]);
$gendreIds = Genders::pluck('id');
DB::table('users')->insert([
'gender_id' => $gendreIds->random(),
...
]);
This will give you gender which exists in database.
Sometimes seed wouldn't give you id's from 1 to 3.
So I think it's not best solution to use rand(1,3).
Good luck!

Answer 2

In your user creation method
Instead of
'gender_id' => $genders->random(),
you can use this
'gender_id' => rand(1,3),

Answer 3

No need to add genders here.You can do that in other seeder or manually do that.Here in your genders id should be in 1,2 & 3 .fixed.THen you can use rand() function here.rand() is a php function .rand() define a random number & you can fixed it value like rand(min,max) so just here use this rand(1,3)
public function run()
{
$genders = DB::table('genders')->insert([
[
'genders' => 'Woman',
],
[
'genders' => 'Woman Looking For Woman',
],
[
'genders' => 'Man',
]
]);//your wish to seed this gender in here
DB::table('users')->insert([
'gender_id' => rand(1,3),
'name' => 'authuser',
'email' => 'authuser#auth.com',
'email_verified_at' => now(),
'password' => Hash::make('auth123456'),
'age' => 18,
'remember_token' => Str::random(10),
'created_at' => Carbon::now(),
'updated_at' => Carbon::now(),
]);
}
