I have a base table named "Projects" And I have another table named "Project Blocks".
I have defined the relationship for projects to Project block as one to many. The Relationship is defined in this way :
namespace App;
use Illuminate\Database\Eloquent\Model;
class Projects extends Model
{
public function projectblocks(){
return $this->hasMany('App\ProjectBlocks','project_id','id');
}
}
I also have one table Named "Project Units" which has realtionship with project block table:
namespace App;
use Illuminate\Database\Eloquent\Model;
class ProjectBlocks extends Model
{
public function projects(){
return $this->belongsTo('App\Projects','project_id','id');
}
public function projectunits(){
return $this->hasMany('App\ProjectUnits');
}
}
I have also defined the table structure inside ModelFactory :
$factory->define(App\Projects::class, function (Faker\Generator $faker) {
return [
'name' => $faker->sentence(5),
...//All other required fields
];
});
And
$factory->define(App\ProjectBlocks::class, function (Faker\Generator $faker) {
return [
'name' => $faker->sentence(5),
... //All other fields comes here
];
});
And for Project Units :
$factory->define(App\ProjectUnits::class, function (Faker\Generator $faker) {
return [
'name' => $faker->sentence(5),
...//Other fields
];
});
Now When I try to seed the above tables I am getting errors :
This is the code to seed the table:
use Illuminate\Database\Seeder;
class ProjectsTableSeeder extends Seeder
{
public function run()
{
factory(App\Projects::class, 20)->create()->each(function($u) {
$u->projectblocks()->save(factory(App\ProjectBlocks::class)->make()->each(function($v) {
$v->projectunits()->save(factory(App\ProjectUnits::class)->create());
})
);//This is line number XXXXXX
});
}
}
I am getting the following error:
[Symfony\Component\Debug\Exception\FatalThrowableError]
Type error: Argument 1 passed to Illuminate\Database\Eloquent\Relations\Has
OneOrMany::save() must be an instance of Illuminate\Database\Eloquent\Model
, boolean given, called in /var/www/html/seederExample/database/seeds/Proje
ctsTableSeeder.php on line XXXXXX
Please Help me to know where I am making a mistake/s.
In case if more code is needed then please comment so that I can add the code.
