Laravel updateOrCreate with hasMany relationship - php

Question

I have users that can have multiple parameters. These are called for example user_param_1, user_param_2, ..., user_param_n. This is dynamic. It is a separate table user_parameters, which stores id, user_id, name and value. The relationship is a belongsTo and hasMany between Users and UserParameters. The problem is:
When editing, I want to keep it dynamically and if the user has an user_param_n+1, it should be created. But I already have problems to write the condition for the existing parameters.
I create myself an userParameters array, which contains from the $request variable only the necessary parameters. The array looks like this:
[
0 => [
"name" => "par1"
"value" => "var1"
]
1 => [
"name" => "par2"
"value" => "var2"
]
2 => [
"name" => "par3"
"value" => "var3"
]
]
Then I want to save it. My controller knows the user, so I can access to $user->id.
foreach ($userParameters as $userParameter) {
$user->parameters()->updateOrCreate(['id' => $user->parameters->id, 'user_id' => $user->id], $userParameter);
}
The issue is, that $user->parameters is an array of eloquent models. The condition is wrong. I can't access id directly. But how I can solve it? I need something like "['id' => [IF-DATABASE-ID-EXISTS-IN-ARRAY-$user-parameters]"... but how in an eloquent way?
Thanks in advance!
Best regards

I think you need to get the existing parameter using user_id and parameter_name cuz it's the uniqueness of that parameter row, if there is no parameter with this name it will create it with user_id & parameter_name and parameter_value passed to updateOrCreate function
foreach ($parameters_from_request as $parameter) {
$user->parameters()
->updateOrCreate(
[
'name' => $parameter['name'] ,
'user_id' => $user->id
],[
'name' => $parameter['name'],
'value'=> $parameter['value']
]);
}
