Question

I have product and auction table. I want to add auction deadline on a specific table using form. when I submit the form the product_id in auction table is not populated and deadline shows time on which form is submited.
Here what I am trying:
I want that the create form get the deadline and store in auction table with product id so I can access it in show method of product.
create.blade.php
#extends('layouts.app')
#section('content')
<div class="mt-3" style="margin-left: 50px;">
<h2>Add new product</h2>
{!! Form::open(['action' => 'ProductsController#store', 'method' => 'POST', 'enctype' =>
'multipart/form-data', 'class' => 'w-50 py-3']) !!}
<div class="form-group">
{{Form::label('name', 'Product Name')}}
{{Form::text('name', '', ['class' => 'form-control', 'placeholder' => 'Product Name'])}}
</div>
<div class="form-group">
{{Form::label('description', 'Product Description')}}
{{Form::textarea('description', '', ['class' => 'form-control', 'placeholder' => 'Product Description', 'rows' => '4'])}}
</div>
<div class="form-group">
{!! Form::Label('category', 'Category') !!}
<select class="form-control" name="category_id">
#foreach($categories as $category)
<option value="{{$category->id}}">{{$category->name}}</option>
#endforeach
</select>
</div>
<div class="form-group">
{{Form::label('price', 'Product Price')}}
{{Form::number('price', '', ['class' => 'form-control', 'placeholder' => 'Product Price'])}}
</div>
<div class="form-group">
{{Form::label('deadline', 'Auction Deadline')}}
{{Form::date('{{$auction->deadline}}', '', ['class' => 'form-control'])}}
</div>
<div class="form-group">
{{Form::label('image', 'Product Image')}}

Product Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{
protected $fillable = [
'name', 'price', 'description', 'image',
];
public function category()
{
return $this->belongsTo('App\Category');
}
public function auction()
{
return $this->hasOne('App\Auction');
}
}
ProductsController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
use App\Product;
use App\Category;
use App\Auction;
class ProductsController extends Controller
{
public function index()
{
$categories = Category::all();
$products = Product::with('category')->latest()->paginate(3);
return view('products.index' ,compact('categories', 'products'));
}
public function create()
{
$categories = Category::all(['id', 'name']);
return view('products.create', compact('categories',$categories));
}
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required',
'description' => 'required',
'category_id' => 'required',
'price' => 'required',
'image' => 'image|nullable',
]);
// Create Product
$product = new Product();
$product->name = request('name');
$product->description = request('description');
$product->category_id = request('category_id');
$product->price = request('price');
$product->image = $fileNameToStore;
$product->save();
$auction = new Auction();
$auction->deadline = request('deadline');
$auction->save();
return redirect('/products')->with('success', 'Product Created');
}
public function show($id)
{
$product = Product::find($id);
return view('products.show', compact('product'));
}
}

Answer 1

you are just creating auction, where is the relation? Delete $product->save(); line. After the $auction->save(); add this line:
$product->auction()->associate($auction);
$product->save();
Final Store method
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required',
'description' => 'required',
'category_id' => 'required',
'price' => 'required',
'image' => 'image|nullable',
]);
// Create Product
$product = new Product();
$product->name = request('name');
$product->description = request('description');
$product->category_id = request('category_id');
$product->price = request('price');
$product->image = $fileNameToStore;
$auction = new Auction();
$auction->deadline = request('deadline');
$auction->save();
$product->auction()->associate($auction);
$product->save();
return redirect('/products')->with('success', 'Product Created');
}
Update for Irrelevant Blade problem
This line is wrong:
{{Form::date('{{$auction->deadline}}', '', ['class' => 'form-control'])}}
You are using blade close string tag in blade string tag.
Should be:
{{Form::date('deadline', '', ['class' => 'form-control'])}}
If auction variable has been passing from controller this will work
