laravel unique validation on foreign key - laravel

Question

I have database table streets in which I am storing name and block_id as foreign key from the blocks table. So I want the name of street should be unique in every block. for example if the name of street is street 1 with block_id 1, it should not be added again with block_id 1 but it should be allowed to add street 1 with block_id 2 or 3. How can I get it with Laravel validation?
My validation Code:
here you can see I am validating uniqueness only on those records which have delete = false.
$validatedValues = $request->validate([
'block' => 'required',
'street' => [
'required',
Rule::unique('streets', 'sName')->where(function ($query) {
return $query->where('delete', false);
})
],
'street_width' => 'required',
]);

Answer 1

Replace this with street key in your code
'name' => [
'required',
Rule::unique('streets')->where(function ($query) use($request) {
return $query->where('name', $request->name)
->where('block_id', $request->block_id);
}),
],

Answer 2

try this one
Create request -> PHP artisan make:request StreetsRequest
in ur controller find the store method or whatever the name u put for storing ur data, and change the (Request $request) to (StreetsRequest $request)
use App\Http\Requests\StreetsRequest;
....
public function store(StreetsRequest $request){
$request->validated();
// Do whatever u want after validate
}
Open your StreetsRequest file and inside the return [] put sth like this
use Illuminate\Validation\Rule;
...
'block_id' => [
'required',
Rule::unique('streets','block_id')->ignore(request('id')),
],
i hope it will work , let us know if u still have any problem, thx

You can try writing custom validation for that
$validator = $request->validate([
'block' => 'required',
'street' => [
function ($attribute, $value, $fail) use($request){
$street= Street::where('delete', false)->where(function ($query)use($request){
$query->where('sName',$request->sName);
$query->where('block_id',$request->block_id );
})->exists();
if($street){
$fail('The '.$attribute.' is invalid.');
}
},
],
]);
I hope for streets table you have Street model
if any issue let me know .
