Add a new item on laravel 4 using different tables - php

Question

This is my Items model . Now i want to add a new item but i get this error: SQLSTATE[23000]: Integrity constraint violation: 1048
<?php
class Items extends Eloquent
{
protected $guarded = [
'id',
];
protected $fillable = [
'name',
'description',
'price',
'brand',
];
protected $table = 'items';
public function user()
{
return $this->hasOne('User', 'user_ID', 'id');
}
public function size()
{
return DB::table('sizes')->select('size')
->where('id', $this->size_ID)->first()->size;
}
public function color()
{
return DB::table('colors')->select('color')
->where('id', $this->color_ID)->first()->color;
}
public function condition()
{
return DB::table('conditions')->select('type')
->where('id', $this->condition_ID)->first()->type;
}
public function category()
{
return DB::table('categories')->select('category')
->where('id', $this->category_ID)->first()->category;
}
public function images()
{
return DB::table('images')->select('image')
->where('item_id', $this->id)->first()->image;
}
}
And this is my post method to save item.
public function store()
{
$item = new Items;
$item->user_ID = Auth::id();
$item->name = Input::get('name');
$item->description = Input::get('description');
$item->price = Input::get('price');
$item->brand = Input::get('brand');
$item->category = Input::get('Category');
$item->condition = Input::get('Condition');
$item->color = Input::get('Color');
$item->save();
}
Here is a picture of category table , condition and color table has the same logic.

Answer 1

You are creating a relationship between User and Item while not using it.
You can set the populate the relationship manually by filling in the id yourself, but then you don't use the power of the Eloquent ORM.
What I would suggest is getting the current user.
And saving it like this.
$item->user()->save($user);
I suggest for the name of the class Item and not Items.
I find it having much more logic and so do most of the programmers.
The table can still be called items.
