I am having problem with available key in the map collection.
The available key use contains method. It should return true if the value of product id in $unavailableProducts does not contain in $products ($value->product_id == $product->id)
What did I do wrong?
$unavailableProducts = $this->unavailableProducts();
$products = $this->products->all();
$allProducts = $products->map(function ($product) use($unavailableProducts) {
return [
'id' => $product->id,
'title' => $product->title,
'available' => $unavailableProducts['result']->contains(function ($value, $key) use ($product) {
if ($value->product_id == $product->id) {
return false;
}
return true;
}),
];
});

First, make sure that $unavailableProductions['result'] is a collection.
Second, change your contains method like this:
$unavailableProducts = $this->unavailableProducts();
$products = $this->products->all();
$allProducts = $products->map(function ($product) use($unavailableProducts) {
return [
'id' => $product->id,
'title' => $product->title,
'available' => $unavailableProducts['result']->contains('id', $product->id),
];
});
The $unavailableProducts['result']->contains('id', $product->id) will determine if the $unaviableProductions['result'] collection has a key id where the value is $product->id
You can try this approach
$policyPackageDetails = PolicyPackage::where('isactive', '=', 1)->where('id', '=', $pid)
->with('policy_package_details')
->select('id',
'title',
'subtitle',
'shorttitle',
)
->get();
$policyPackageDetails = $policyPackageDetails ->map(function ($item){
return collect([
'id' => $item->id,
'title' => $item->title,
'subtitle' => $item->subtitle,
'short_title' => $item->shorttitle,
'policy_package_details' => $item->policy_package_details->map(function ($details){
return [
'attribute_name' => $details->attname,
'attribute_value' => $details->attvalue,
];
}),
]);
});
here fetching data from relational models, remaining & filtering them, the output will be like
[
{
"id": 61,
"title": " Health (Platinum)",
"subtitle": "for 1 year",
"short_title": "HL-SHP-1",
"policy_package_details": [
{
"attribute_name": "in",
"attribute_value": "180000"
},
{
"attribute_name": "out",
"attribute_value": "20000"
}
]
}
]
