UpdateOrCreate Model Object - php

Question

I am using Laravel 5.5 and I am declaring my model object the following:
$product = new product();
$product->name = $coinArr[$key];
$product->symbol = $symbolArr[$key];
$product->current_price = $priceArr[$key];
///save image to public folder
$fileName = basename($imgArr[$key]);
Image::make($imgArr[$key])->save(public_path('images/' . $fileName));
$product->asset_logo = $fileName;
//$product->updateOrCreate();
App/Product::updateOrCreate($product);
If the product does not exist in the database I would like to create it else just update it.
I tried the following two ways to use the updateOrCreate method. However, I receive the following error for App/Product::updateOrCreate($product);:
Type error: Too few arguments to function Illuminate\Database\Eloquent\Builder::updateOrCreate(), 0 passed in C:\Users\admin\Desktop\Coding Projects\laravel_proj\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Model.php on line 1455 and at least 1 expected
And the following error for $product->updateOrCreate();:
Type error: Too few arguments to function Illuminate\Database\Eloquent\Builder::updateOrCreate()
Any suggestions how to use updateOrCreate with my model object?
I appreciate your replies!

Answer 1

When you use updateOrCreate, you need to choose which attributes are used to determine if the product exists already. The function takes 2 arrays:
product::updateOrCreate([
'name' => $coinArr[$key] //Laravel will check if this model exists by name
],[
'symbol' => $symbolArr[$key] //if exists, will update symbol. if doesnt exist, will create new with this name and symbol
]);

That's not how the updateOrCreate() method works. In the first parameter you put an array with search conditions. If you want to search existing route by name for example, the correct syntax will be:
Product::updateOrCreate(
[
'name' => $coinArr[$key]
],
[
'symbol' => $symbolArr[$key],
'current_price' => $symbolArr[$key],
'asset_logo' => $fileName
]
);
The second parameter is array for creating a new object.
