Laravel Eloquent saveMany does not accept second attribute - php

Question

As I think it is typically as the documentaion I have tried to use saveMany regarding its parameters as Model objects.
I have a model named Set and it hasMany Equipment so, from the from that creates a set I submit many fields of Equipment in-order to be saved as the following:
//Store method of SetController
$set = new Set();
$set->title = request('title');
$set->eqtype_id = request('eqtype');
$set->product_id = request('product');
$set->parts_count = request('parts_count');
$eq = request('equipments');
$set->equipments()->saveMany(array_map(function($n){return new \App\Equipment(['title' => $n, 'eqtype_id' => request('eqtype')]);}, $eq));
$set->save();
However, I always get the error message about that eqtype_id does not has a default value:
SQLSTATE[HY000]: General error: 1364 Field 'eqtype_id' doesn't have a
default value (SQL: insert into equipments (title, set_id,
updated_at, created_at) values (A-1, , 2017-03-18 12:07:30,
2017-03-18 12:07:30))
I thought that, may be, request('eqtype') is not accessible from the array_map callback, so I replaced it with a fixed number as follows:
$set->equipments()->saveMany(array_map(function($n){return new \App\Equipment(['title' => $n, 'eqtype_id' => 1]);}, $eq));
But also the error is same, it seems like a problem with either saveMany or array_map. I don't know how to fix this issue!
Notice
The model Equipment is related with the both model Set and Eqytpe as follows:
//Equipment model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
/**
* App\Equipment
*
* #mixin \Eloquent
*/
class Equipment extends Model
{
public $table = "equipments";
protected $fillable = ['title'];
public function set()
{
return $this->belongsTo(Set::class);
}
public function eqtype()
{
return $this->belongsTo(Eqtype::class);
}

I kind of had the same problem and this is what I did to fix it:
I had a One to Many relationship between a Product and Image and I wanted on a product creation add all the images related to it
// Create post
public function store(Request $request)
{
$newProduct = Product::create([
'name' => $request->name,
'description' => $request->description,
'price' => $request->price,
'stock_items' => $request->stock_items,
]);
for ($i = 0; $i < count($request->image_path); $i++) {
$newProduct->image()->saveMany([
new Image(['image_path' => $request->image_path[$i]])
]);
}
}
Don't forget the relationship functions & to create multiple input with the same name : name='image_path[]'
